15 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) At the end of 2022, 65 percent of the Western United States was in severe drought, the result of a two decades long mega drought in the Colorado River Basin that had captured headlines around the world. However, it was flooding, not drought, that was making headlines when we began our research for this story about OpenET, a revolutionary new online platform geared towards helping farmers and water managers monitor and reduce water use in watersheds where supplies were not keeping up with demand. The start of 2023 brought flooding to many counties in California, leaving 68 percent of the state with suddenly little to no drought. And caused Forrest Melton, the NASA Project Scientist for OpenET and Associate Program Manager for agriculture and water resources with the NASA Earth Action program, to pause our video interview after a tree fell down outside his Bay Area home on a rainy day in March, 2023. Coming online again after calling the fire department, Melton didn’t seem all too optimistic that the wet conditions would last. “California tends to swing between the two extremes of drought and flood,” Melton said. He referenced the 2016/17 winter which had particularly high precipitation but was followed by dry conditions during the following years, before the relief brought by the heavy rains, and flooding, in early 2023. According to NOAA’s National Integrated Drought Information System it will take more than one wet winter to replenish groundwater in many parts of the western United States. Groundwater levels across the California Central Valley and many parts of the Ogallala Aquifer continue to decline. The need for better water management remains essential, and yet the data necessary to support new approaches has not been broadly available. Enter the OpenET project, a multi-disciplinary, collaborative effort to make satellite-based evapotranspiration (ET) data available to the public. Melton describes the project as providing invaluable and scientifically robust data at all scales, “that can be used to support day to day decision making and long range planning to try to solve some really long standing and important water management challenges in the West.” What is Evapotranspiration? Evapotranspiration is the combined process of evaporation and transpiration, both of which transfer water from the land surface to the atmosphere as water vapor. Evaporation transforms water from the surface of the ground or bodies of water into water vapor, while transpiration is water vapor that is evaporated from plant tissues and escapes through the stomata, the tiny pores in plant leaves and stems. It is a process that is happening all around us almost all the time, but because water vapor is invisible to the human eye, it is very hard to measure on the ground. A conceptual diagram of near-surface hydrology.M. W. Toews To understand the effect evapotranspiration has on a local water cycle, picture a large decorative fountain. Typically, these fountains recycle the same water over and over. As a fountain runs, water is pumped out of the fountain heads, falls back into the fountain’s basin, and then flows back through the pipe system before starting the process all over again. We can think of the water remaining within this fountain’s local water system as non-consumptive water use. Some water, however, will be lost from the fountain’s local water system by evaporating from the pool’s surface or mist from the fountain’s spray. Imagine the fountain also has lily pads growing in its basin. The lily pads will use the fountain’s water to survive and grow, losing some of that water to transpiration. The total water lost is evapotranspiration, and is considered consumptive water use, because it cannot be reused by the fountain. Tracking evapotranspiration can tell you how much water is removed or “depleted” from a local water system, and how much water needs to be added back in to support plant growth and maintain a healthy balance between water supply and water use. If too much water leaves the fountain, it will stop running. If too much water is added, it will overflow. These concepts can be applied more broadly to the hydrologic cycle as a whole, and evapotranspiration data can play an important part in designing and implementing sustainable water management practices to combat larger issues like drought, as well as both short and long-term reductions in water availability. Historically, ET data have been obtained from ground-based instruments and methods, such as weighing lysimeters, which weigh soil and plants to track the water volume lost by evaporation or transpiration. Another common method is called eddy covariance, which calculates the amount of water vapor transported away from the land surface by wind eddies as they move across the land surface. But both are expensive and difficult to install and maintain, and measurements are only representative of a small portion of an individual agricultural field. It is cost prohibitive to collect these measurements over larger areas. What makes OpenET different? The OpenET team saw the important niche left open by traditional evapotranspiration measurement methods and filled it. They built upon decades of research funded by NASA, USDA and USGS and developed a new platform that can take easily accessible and already available data from satellite programs, like Landsat, and combine it with weather data to calculate the ET for every quarter acre of land. Satellites can record information like the Earth’s surface temperature and how much of the incoming light from the sun is being reflected back out to space. OpenET is able to use physically-based mathematical models to combine the satellite and weather data and output accurate data on evapotranspiration rates and volumes. This information is then made easily accessible through OpenET’s Data Explorer, a free web-based tool that allows anyone with an internet connection to access the data OpenET provides. Users begin by selecting an area of interest from a map of the western United States that provides data at the satellite resolution of a quarter-acre, and also broken down into known areas of interest and individual agricultural fields, each color coded with a heat map of evapotranspiration. Cooler colors indicate higher rates of evapotranspiration while warmer colors indicate lower rates. Users can zoom into specific areas on the map, and with just a click, a chart pops up showing the evapotranspiration trends for a given area, for the current year and the past five years. The chart can show monthly ET trends, useful for understanding seasonal fluctuations, and also cumulative trends, useful for understanding year-to-year changes in evapotranspiration. “The OpenET team took a user-driven design approach from the beginning, and each element of the Data Explorer and the open data services is there because a water manager or farmer asked for it,” Melton explained. As we played around with the map, it became apparent how much work was put into developing this project. Scientists needed to improve models and assess the accuracy of data, programmers had to develop the user interface and data services, designers needed to make the interface intuitive enough to be impactful, agriculture and environmental groups needed to help validate the model’s accuracy, and users of all types needed to provide requirements and then test the product to make sure their needs were actually met. The OpenET consortium includes NASA, USGS, USDA Agricultural Research Service (ARS), Environmental Defense Fund (EDF), Google Earth Engine, California State University Monterey Bay (CSUMB), Desert Research Institute (DRI), Habitat Seven, Chapman University, Cornell University, University of Nebraska-Lincoln and close to a dozen other universities and experts across the U.S. NASA Ames Research Center and CSUMB have played key roles in the scientific and technical leadership of the effort from the outset, working closely with DRI, EDF and the recently formed non-profit OpenET, Inc. In addition, over 100 partners from the water management, agriculture and conservation community provided user requirements and assisted with the design and testing of the OpenET platform and tools. “OpenET would not be possible without the contributions of each one of those partners,” Melton said. “Both on the implementation side and those who are translating the data from OpenET into solutions to long standing challenges.” Map of farmlands showing ET data for 2024. The cooler colors represent higher levels of evapotranspiration (ET), while warmer colors indicate areas with less ET.OpenET Models like those built into OpenET can be extremely useful tools for understanding patterns in ET and water use, but are only helpful if their accuracy is known. The OpenET science team recently completed the largest accuracy assessment to date for field-scale satellite-based ET data, comparing the satellite data to ground-based measurements at more than 150 sites across the U.S. Led by John Volk of the Desert Research Institute, the study was published in Nature Water earlier this year. A key finding was that across all sites, an ensemble value computed from six different ET models performed the best overall, leveraging the strengths of each individual satellite-driven model. However, the study also found that some models performed best for particular crop types or regions, which is important information for water managers and farmers who need the most accurate data possible. Publishing the results as an open access study with all data and analysis made publicly available was also important to build trust in the data. While the study highlighted some limitations of the models and priorities for future research, the rigorous and reproducible accuracy assessment helps to build user confidence that they can use the data, while being aware of the expected accuracy for different applications of the data. Bridging the Gap Between Farmers and Resource Managers OpenET has already contributed to one significant win for farmers that affects how water use will be monitored and reported in the Sacramento-San Joaquin Delta. This inland river delta covers 750,000 acres and is an important water resource in California, but one where accelerated demand combined with habitat loss and water quality issues has led to major concerns. In the Delta, large portions of the agricultural land are below sea level. Levees protect the fields and contain the river channels that supply water for irrigation. In 2023, the state began requiring farmers to maintain a water meter or measuring device on each diversion, where water is diverted from a river for irrigation. However, this measurement proved challenging and costly as there are thousands of diversions in the Delta, and the measuring equipment was inaccurate and difficult to maintain in this environment. In addition, water users also had to pay for meters at the locations where water that drained from the fields was pumped back over the levees and into the river channels. The Sacramento-San Joaquin River Delta is a major water resource in California.Matthew Trump “Mostly, what the state was interested in was the consumptive use: how much (water) was actually removed from the supply in that region,” Melton said. “So, it’s the perfect place for using OpenET because evapotranspiration really is the majority of the consumptive use in the Delta, if not all of it.” After the launch of OpenET, farmers in the Delta worked with the Delta Watermaster, the California State Water Resources Control Board, the OpenET team and the Delta Measurement Consortium to develop an alternative compliance plan that used OpenET data to help streamline the water use required reporting for this complex region. Once the alternative compliance plan was approved, Forrest Melton and Will Carrara of NASA worked with the state Water Resources Control Board, the Delta Watermaster and water management agencies, and Jordan Harding of HabitatSeven to implement this solution. The Delta Alternative Compliance Plan, also known as the Delta ACP, allows farmers to use OpenET data to estimate their water usage; enabling farmers to complete their use reports in a matter of minutes. “It’s the first time that satellite-based evapotranspiration data has been automatically integrated with a state-managed water reporting system,” Melton said. Last year, more than 70% of farmers in the Bay-Delta region chose to use OpenET and to report their water use through the Delta ACP website, and they expect this percentage to continue to increase over time. “The best part is that it is saving farmers hundreds of hours on preparing and submitting reports, avoiding millions of dollars in costs for farmers to deploy and maintain meters, and giving the state consistent and reproducible data on water use that has been reviewed and approved by the water user,” Melton said. According to Delta Watermaster, Jay Ziegler, this approach has a clear benefit in the unique water flow setting of the Delta. “In reality, OpenET – and the use of publicly accessible data measuring ET is the only way to really discern consumptive use of water in the Delta on a reliable basis,” Ziegler said. “Candidly, we don’t really have a viable “plan B” in the absence of applying Open ET for water use reporting.” In reality, OpenET – and the use of publicly accessible data measuring ET is the only way to really discern consumptive use of water in the Delta on a reliable basis. Jay ziegler Sacramento-San Joaquin Delta Watermaster Water Beyond Borders As water scarcity is increasingly becoming an urgent issue all around the world, it’s easy to imagine how many countries could benefit from OpenET data. OpenET’s first international partnership is led by Anderson Ruhoff, a professor in Hydrology and Remote Sensing at the Federal University of Rio Grande do Sul, Brazil, where his team developed an evapotranspiration model called geeSEBAL for Brazil’s Water Agency. Ruhoff learned about OpenET while he was in the US on a visiting professorship in Nebraska. He was intrigued and reached out to Melton who encouraged him to attend an upcoming conference in Reno, Nevada, where OpenET would be featured. The conference was due to start in just a few days time. “So I had to find a last minute ticket to Reno and I’m glad I bought it, because when I arrived there they invited me to join Open ET. It was quite a coincidence,” Ruhoff said, smiling as he remembered the spontaneous decision. “We adapted our model for the US and started to participate in their work.” In March, 2024, Ruhoff and OpenET launched an extension of the tool, called OpenET Brazil, with financial support from the Agência Nacional de Águas e Saneamento Básico (ANA), the Brazilian national water agency. The tool, called OpenET Brazil, will have similar goals as OpenET in the U.S., and the data collected will help improve Open ET’s accuracy overall. Melton feels this will be a “great test case” for both working with new environmental conditions (in Brazil there frequently is more cloud cover than in the US during key parts of the growing season) and also developing new collaborations. “The partnership will help us figure out how we can work with international partners to make the ET data useful,” Melton said. “The key aspect of our approach to geographic expansion is that leading scientists in each country and region, like Dr. Ruhoff, will lead the implementation, accuracy assessment, and the development of applications and partnerships for their country.” Brazil has one of the world’s largest sources of freshwater, the Amazon River, and yet it can still be affected by drought. This is partly due to the fact that deforestation in the Amazon Rainforest has an impact on the entire region’s water cycle. Trees draw water up from the soil and during photosynthesis they release vapor into the atmosphere. This water vapor will accumulate and form precipitation. Trees are “basically a huge water pump,” Ruhoff said, and the Amazon Rainforest is large enough that it helps to produce the rainy season. But when deforestation is allowed to happen over large areas, that mechanism is interrupted. As a result of this disruption, the dry season is predicted to intensify, becoming longer and dryer, which in turn can affect crop production in Brazil as well as the rainfall that is critical for sustaining water supplies in Brazil and other areas of South America. “Water doesn’t see borders. It doesn’t follow our rules,” Ruhoff said. “Deforestation in one place can affect people thousands of kilometers away.” Water doesn’t see borders. It doesn’t follow our rules. Deforestation in one place can affect people thousands of kilometers away. Anderson Ruhoff Professor of Hydrology and Remote Sensing, Federal University of Rio Grande do Sul, Brazil Studying evapotranspiration can reveal the impacts of deforestation with even more clarity. And importantly, it’s also public information. “So not only the farmers and water managers but every citizen can check how much water is being used in their area, especially during drought. It’s democratic information in that way,” Ruhoff said. “I think it’s important to have this information openly available and to try and reach as many people as possible.” Melton feels there’s the potential to expand the project, if more people like Ruhoff are there to lead the way. “There’s huge potential, but there do need to be stakeholders that come to the table and say that this is something that they’re interested in,” Melton said. “Water is so important and at times so contentious that it’s really important the data is seen as trusted. When there is a local leader, that substantially increases the likelihood that it will be trusted, and most importantly, used to bring people together to develop solutions.” The geeSEBAL application that Anderson Ruhoff’s team developed, which now informs the OpenET platform. Science Direct/Anderson Ruhoff Even when you live in a water-scarce region like California it’s easy to take water for granted. What platforms like OpenET can do for us, however, is make water, even in its most diffuse form, more visible to everyone.

A SpaceX Falcon Heavy rocket carrying NASA’s Europa Clipper spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 12:06 p.m. EDT on Monday, Oct. 14, 2024. After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.Credit: NASA/Kim Shiflett NASA’s Europa Clipper has embarked on its long voyage to Jupiter, where it will investigate Europa, a moon with an enormous subsurface ocean that may have conditions to support life. The spacecraft launched at 12:06 p.m. EDT Monday aboard a SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida. The largest spacecraft NASA ever built for a mission headed to another planet, Europa Clipper also is the first NASA mission dedicated to studying an ocean world beyond Earth. The spacecraft will travel 1.8 billion miles (2.9 billion kilometers) on a trajectory that will leverage the power of gravity assists, first to Mars in four months and then back to Earth for another gravity assist flyby in 2026. After it begins orbiting Jupiter in April 2030, the spacecraft will fly past Europa 49 times. “Congratulations to our Europa Clipper team for beginning the first journey to an ocean world beyond Earth,” said NASA Administrator Bill Nelson. “NASA leads the world in exploration and discovery, and the Europa Clipper mission is no different. By exploring the unknown, Europa Clipper will help us better understand whether there is the potential for life not just within our solar system, but among the billions of moons and planets beyond our Sun.” Approximately five minutes after liftoff, the rocket’s second stage fired up and the payload fairing, or the rocket’s nose cone, opened to reveal Europa Clipper. About an hour after launch, the spacecraft separated from the rocket. Ground controllers received a signal soon after, and two-way communication was established at 1:13 p.m. with NASA’s Deep Space Network facility in Canberra, Australia. Mission teams celebrated as initial telemetry reports showed Europa Clipper is in good health and operating as expected. “We could not be more excited for the incredible and unprecedented science NASA’s Europa Clipper mission will deliver in the generations to come,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Everything in NASA science is interconnected, and Europa Clipper’s scientific discoveries will build upon the legacy that our other missions exploring Jupiter — including Juno, Galileo, and Voyager — created in our search for habitable worlds beyond our home planet.” The main goal of the mission is to determine whether Europa has conditions that could support life. Europa is about the size of our own Moon, but its interior is different. Information from NASA’s Galileo mission in the 1990s showed strong evidence that under Europa’s ice lies an enormous, salty ocean with more water than all of Earth’s oceans combined. Scientists also have found evidence that Europa may host organic compounds and energy sources under its surface. If the mission determines Europa is habitable, it may mean there are more habitable worlds in our solar system and beyond than imagined. “We’re ecstatic to send Europa Clipper on its way to explore a potentially habitable ocean world, thanks to our colleagues and partners who’ve worked so hard to get us to this day,” said Laurie Leshin, director, NASA’s Jet Propulsion Laboratory in Southern California. “Europa Clipper will undoubtedly deliver mind-blowing science. While always bittersweet to send something we’ve labored over for years off on its long journey, we know this remarkable team and spacecraft will expand our knowledge of our solar system and inspire future exploration.” In 2031, the spacecraft will begin conducting its science-dedicated flybys of Europa. Coming as close as 16 miles (25 kilometers) to the surface, Europa Clipper is equipped with nine science instruments and a gravity experiment, including an ice-penetrating radar, cameras, and a thermal instrument to look for areas of warmer ice and any recent eruptions of water. As the most sophisticated suite of science instruments NASA has ever sent to Jupiter, they will work in concert to learn more about the moon’s icy shell, thin atmosphere, and deep interior. To power those instruments in the faint sunlight that reaches Jupiter, Europa Clipper also carries the largest solar arrays NASA has ever used for an interplanetary mission. With arrays extended, the spacecraft spans 100 feet (30.5 meters) from end to end. With propellant loaded, it weighs about 13,000 pounds (5,900 kilograms). In all, more than 4,000 people have contributed to Europa Clipper mission since it was formally approved in 2015. “As Europa Clipper embarks on its journey, I’ll be thinking about the countless hours of dedication, innovation, and teamwork that made this moment possible,” said Jordan Evans, project manager, NASA JPL. “This launch isn’t just the next chapter in our exploration of the solar system; it’s a leap toward uncovering the mysteries of another ocean world, driven by our shared curiosity and continued search to answer the question, ‘are we alone?’” More About Europa Clipper Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet. Managed by Caltech in Pasadena, California, NASA JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with NASA JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NASA’s Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at NASA Kennedy, managed the launch service for the Europa Clipper spacecraft.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Felipe Valdez, a NASA engineer at Armstrong Flight Research Center’s Dale Reed Subscale Flight Research Laboratory, stands next to a subscale model of the Hybrid Quadrotor (HQ-90) aircraft. NASA / Charles Genaro Vavuris Felipe Valdez is someone who took advantage of every possible opportunity at NASA, working his way from undergraduate intern to his current job as a flight controls engineer. Born in the United States but raised in Mexico, Valdez faced significant challenges growing up. “My mom worked long hours, my dad battled addiction, and eventually, school became unaffordable,” Valdez said. Determined to continue his education, Valdez made the difficult choice to leave his family and return to the U.S. But as a teenager, learning English and adapting to a new environment was a culture shock for him. Despite these changes, his curiosity for subjects such as math and science never wavered. “As a kid, I’d always been good with numbers and fascinated by how things worked. Engineering combined both,” Valdez said. “This sparked my interest.” While he pursued an undergraduate degree in mechanical engineering from California State University, Sacramento, guidance from his professor, Jose Granda, proved to be pivotal. “He encouraged me to apply for a NASA internship,” Valdez said. “He’d actually been a Spanish-language spokesperson for a [space] shuttle mission, so hearing about someone with my background succeed gave me the confidence I needed to take that step.” Valdez’s hard work paid off – he was selected as a NASA Office of STEM Engagement intern at the agency’s Johnson Space Center in Houston. There, he worked on software development for vehicle dynamics, actuators, and controller models for a space capsule in computer simulations. “I couldn’t believe it,” Valdez said. “Getting that opportunity changed everything.” This internship opened the door to a second with NASA this time at the agency’s Armstrong Flight Research Center in California. He had the chance to work on flight computer development for the Preliminary Research Aerodynamic Design to Lower Drag, an experimental flying wing design. After these experiences, he was later accepted as an intern for NASA’s Pathways Program, a work-study program that offers the possibly of full-time employment at NASA after graduation. “That was the start of my career at NASA, where my passion for aeronautics really took off,” he said. Valdez was the first in his family to pursue higher education, earning his bachelor’s degree from Sacramento State and his master’s in mechanical and aerospace engineering from the University of California, Davis. Today, he works as a NASA flight controls engineer under the Dynamics and Controls branch at Armstrong. Most of his experience has focused on flight simulation development and flight control design, particularly for distributed electric propulsion aircraft. “It’s rewarding to be part of a group that’s focused on making aviation faster, quieter, and more sustainable,” Valdez said. “As a controls engineer, working on advanced aircraft concepts like distributed electric propulsion allows me design algorithms to directly control multiple motors, enhancing safety, controllability, and stability, while enabling cleaner, and quieter operations that push the boundaries of sustainable aviation.” Throughout his career, Valdez has remained proud of his heritage. “I feel a strong sense of pride knowing that inclusion is one of our core values, opportunities are within reach for anyone at NASA.” Facebook logo @NASA@NASAaero@NASA_es @NASA@NASAaero@NASA_es Instagram logo @NASA@NASAaero@NASA_es Linkedin logo @NASA Explore More 2 min read A Serendipitous NASA Family Reunion Article 1 day ago 2 min read Una reunión familiar de la NASA por casualidad Article 1 day ago 24 min read NASA Celebrates Hispanic Heritage Month 2024 Article 3 days ago Keep Exploring Discover More Topics From NASA Missions Artemis Aeronautics STEM Explore NASA’s History Share Details Last Updated Oct 13, 2024 EditorJim BankeContactJessica Arreolajessica.arreola@nasa.govLocationArmstrong Flight Research Center Related TermsAeronauticsArmstrong Flight Research CenterHispanic Heritage Month View the full article

Curiosity captured this long-distance Remote Micro Imager (RMI) image using the Chemistry & Camera (ChemCam) aboard the rover on sol 4329 — Martian day 4,329 of the Mars Science Laboratory mission — on Oct. 10, 2024 at 02:30:12 UTC. NASA/JPL-Caltech/LANL Earth planning date: Friday, Oct. 11, 2024 This blogger is in the United Kingdom, just north of London, where we yesterday had beautiful night skies with a red aurora that was even visible with the unaided eye, and looked stunning on photographs. That reminded me of the solar storm that made it all the way to Mars earlier this year. Here is my colleague Deborah’s blog about it: “Aurora Watch on Mars.” And, of course, that was a great opportunity to do atmospheric science and prepare for future crewed missions, to assess radiation that future astronauts might encounter. You can read about it in the article, “NASA Watches Mars Light Up During Epic Solar Storm.” But now, back from shiny red night skies north of London, and auroras on Mars six months ago, to today’s planning! Power — always a negotiation! Today, I was the Science Operations Working Group chair, the one who has to watch for the more technical side of things, such as the question if all the activities will fit into the plan. Today there were many imaging ideas to capture the stunning landscape in detail with Mastcam and very close close-ups with the long-distance imaging capability of ChemCam (RMI). Overall, we have two long-distance RMIs in the plan to capture the details of the ridge we are investigating. You can see in the accompanying image an example from last sol of just how many stunning details we can see. I so want to go and pick up that smooth white-ish looking rock to find out if it is just the light that makes it so bright, or if the surface is different from the underside… but that’s just me, a mineralogist by training, used to wandering around a field site! Do you notice the different patterns — textures as we call them in geology — on the rocks to the left of that white-ish rock and the right of it? So much stunning detail, and we are getting two more RMI observations of 10 frames each in today’s plan! In addition there are more than 80 Mastcam frames planned. Lots of images to learn from! Chemistry is also featuring in the plan. The rover is stable on its wheels, which means we can get the arm out and do an APXS measurement on the target “Midnight Lake,” which MAHLI also images. The LIBS investigations are seconding the APXS investigation on Midnight Lake, and add another target to the plan, “Pyramidal Pinnacle.” On the third sol there is an AEGIS, the LIBS measurement where the rover picks its own target before we here on Earth even see where it is! Power was especially tight today, because the CheMin team does some housekeeping, in particular looking at empty cells in preparation for the next drill. The atmosphere team adds many investigations to look out for dust devils and the dustiness of the atmosphere, and APXS measures the argon content of the atmosphere. This is a measure for the seasonal changes of the atmosphere, as argon is an inert gas that does not react with other components of the atmosphere. It is only controlled by the temperature in various places of the planet — mainly the poles. DAN continues to monitor water in the subsurface, and RAD — prominently featured during the solar storm I was talking about earlier — continues to collect data on the radiation environment. Let’s close with a fun fact from planning today: During one of the meetings, the rover drivers were asked, “Are you driving backwards again?” … and the answer was yes! The reason: We need to make sure that in this rugged terrain, with its many interesting walls (interesting for the geologists!), the antenna can still see Earth when we want to send the plan. So the drive on sol 4332 is all backwards. I am glad we have hazard cameras on the front and the back of the vehicle!

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A SpaceX Falcon Heavy rocket with the Europa Clipper spacecraft aboard is seen at Launch Complex 39A as preparations continue for the mission, Sunday, Oct. 13, at NASA’s Kennedy Space Center in Florida. NASA Find details about the launch sequences for the orbiter, which is targeting an Oct. 14 liftoff on its mission to search for ingredients of life at Jupiter’s moon Europa. In less than 24 hours, NASA’s Europa Clipper spacecraft is slated to launch from the agency’s Kennedy Space Center in Florida aboard a Falcon Heavy rocket. Its sights are set on Jupiter’s ice-encased moon Europa, which the spacecraft will fly by 49 times, coming as close as 16 miles (25 kilometers) from the surface as it searches for ingredients of life. Launch is set for 12:06 p.m. EDT on Monday, Oct. 14, with additional opportunities through Nov 6. Each opportunity is instantaneous, meaning there is only one exact time per day when launch can occur. Plans to launch Europa Clipper on Oct. 10 were delayed due to impacts of Hurricane Milton. NASA’s Europa Clipper is the first mission dedicated to studying Jupiter’s icy moon Europa, one of the most promising places in our solar system to find an environment suitable for life outside of Earth. With its massive solar arrays extended, Europa Clipper could span a basketball court (100 feet, or 30.5 meters, tip to tip). In fact, it’s the largest spacecraft NASA has ever built for a planetary mission. The journey to Jupiter is a long one — 1.8 billion miles (2.9 billion kilometers) — and rather than taking a straight path there, Europa Clipper will loop around Mars and then Earth, gaining speed as it swings past. The spacecraft will begin orbiting Jupiter in April 2030, and in 2031 it will start making those 49 science-focused flybys of Europa while looping around the gas giant. The orbit is designed to maximize the science Europa Clipper can conduct and minimize exposure to Jupiter’s notoriously intense radiation. But, of course, before any of that can happen, the spacecraft has to leave Earth behind. The orbiter’s solar arrays are folded and stowed for launch. Testing is complete on the spacecraft’s various systems and its payload of nine science instruments and a gravity science investigation. Loaded with over 6,060 pounds (2,750 kilograms) of the propellant that will get Europa Clipper to Jupiter, the spacecraft has been encapsulated in the protective nose cone, or payload fairing, atop a SpaceX Falcon Heavy rocket, which is poised for takeoff from historic Launch Complex 39A. Launch Sequences The Falcon Heavy has two stages and two side boosters. After the side boosters separate, the core stage will be expended into the Atlantic Ocean. Then the second stage of the rocket, which will help Europa Clipper escape Earth’s gravity, will fire its engine. Technicians encapsulated NASA’s Europa Clipper spacecraft inside payload fairings on Wednesday, Oct. 2, at NASA’s Kennedy Space Center in Florida. The fairings will protect the spacecraft during launch as it begins its journey to explore Jupiter’s icy moon Europa. NASA/Ben Smegelsky Once the rocket is out of Earth’s atmosphere, about 50 minutes after launch, the payload fairing will separate from its ride, split into two halves, and fall safely back to Earth, where it will be recovered and reused. The spacecraft will then separate from the upper stage about an hour after launch. Stable communication with the spacecraft is expected by about 19 minutes after separation from the rocket, but it could take somewhat longer. About three hours after launch, Europa Clipper will deploy its pair of massive solar arrays, one at a time, and direct them at the Sun. Mission controllers will then begin to reconfigure the spacecraft into its planned operating mode. The ensuing three months of initial checkout include a commissioning phase to confirm that all hardware and software is operating as expected. While Europa Clipper is not a life-detection mission, it will tell us whether Europa is a promising place to pursue an answer to the fundamental question about our solar system and beyond: Are we alone? Scientists suspect that the ingredients for life — water, chemistry, and energy — could exist at the moon Europa right now. Previous missions have found strong evidence of an ocean beneath the moon’s thick icy crust, potentially with twice as much liquid water as all of Earth’s oceans combined. Europa may be home to organic compounds, which are essential chemical building blocks for life. Europa Clipper will help scientists confirm whether organics are there, and also help them look for evidence of energy sources under the moon’s surface. This artist’s concept depicts NASA’s Europa Clipper spacecraft in orbit at Jupiter as it passes over the gas giant’s icy moon Europa (lower right). Scheduled to arrive at Jupiter in April 2030, the mission will be the first to specifically target Europa for detailed science investigation. NASA/JPL-Caltech More About Europa Clipper Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet. Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) for NASA’s Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland; NASA’s Marshall Space Flight Center in Huntsville, Alabama; and NASA’s Langley Research Center in Hampton, Virginia.

Credit: NASA While in Milan for international meetings, NASA Administrator Bill Nelson was among the witnesses as Estonia signed the Artemis Accords and became the 45th nation to join the United States and other signatories agreeing to the safe, transparent, and responsible exploration of the Moon, Mars, and beyond. The signing ceremony took place ahead of Italy hosting the 75th International Astronautical Congress beginning Monday, Oct. 14, where government and space officials from signatory countries will discuss advancing implementation of the Artemis Accords, among other topics. “We welcome Estonia’s signing of the Artemis Accords, which will open the door for more international collaboration,” said Nelson. “This decision also strengthens our family of nations, united by a common cause, and builds on our commitment to explore space for the benefit of humanity under the sound principles of the accords.” Erkki Keldo, Estonia’s minister of economy and industry, signed the Artemis Accords. Rahima Kandahari, deputy assistant secretary for the U.S. State Department and Lisa Campbell, CSA (Canadian Space Agency) president, also participated in the event. “Estonia is well known as the leading country in e-governance, and it is a great honor for us to enter a next level in space exploration, said Keldo. “We are more than interested to share our knowledge with the global space community to make future collaboration in space exploration a success for humankind. I am sure that joining the Artemis Accords will open attractive opportunities to Estonian enterprises too, to share their valuable knowledge and competences.” In 2020, the United States and seven other nations were the first to sign the Artemis Accords, which identified an early set of principles promoting the beneficial use of space for humanity. The accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data. The commitments of the Artemis Accords and efforts by the signatories to advance implementation of these principles support the safe and sustainable exploration of space. More countries are expected to sign in the coming weeks and months.

Martinez-Cruz is serving in the United States Marine Corps and is stationed at Marine Corps Air Station Miramar.NASA / Jessica Arreola Growing up in Puerto Rico, Yomayra Cruz-Diaz didn’t imagine that one day she would work at NASA. Today, she serves as technical project coordinator at NASA’s Langley Research Center in Virginia, supporting its Aeronautics Research Directorate. Cruz-Diaz’s position requires her to travel in support of public engagement events and recently she supported NASA’s presence at the Miramar Airshow in San Diego, California where the agency’s booth featured Spanish-language STEM materials. Something, or rather, someone, made this event especially unique for Cruz-Diaz: Her son, Israel Martinez-Cruz, is currently serving in the United States Marine Corps and is stationed at Marine Corps Air Station Miramar. In a stroke of serendipity, they were both working the same event for their respective employers. Living on opposite sides of the country, they hadn’t seen each other in person for nearly a year. With surprise and joy, they hugged. Growing up in a Puerto Rican household, conversations about core values revolved around family, Martinez-Cruz said. He recalled seeing his mom work at NASA and feeling inspired by her work ethic. That level of commitment ran in the family. “Israel and I would carpool,” she said. “He would drop me off at Langley and then he would go on his way to his aircraft mechanic school.” Martinez-Cruz serves as an air traffic controller, work that Cruz-Diaz knew about but had never seen in person. “He’s explained to me what his job entails but taking a tour of his job site gives me a whole new understanding,” she said after a tour of the air traffic control tower.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The puzzling surface of Jupiter’s icy moon Europa looms large in this reprocessed color view made from images taken by NASA’s Galileo spacecraft in the late 1990s. The images were assembled into a realistic color view of the surface that approximates how Europa would appear to the human eye. NASA/JPL-Caltech/SETI Institute With a spacecraft launching soon, the mission will try to answer the question of whether there are ingredients suitable for life in the ocean below Europa’s icy crust. Deep down, in an ocean beneath its ice shell, Jupiter’s moon Europa might be temperate and nutrient-rich, an ideal environment for some form of life — what scientists would call “habitable.” NASA’s Europa Clipper mission aims to find out. NASA now is targeting launch no earlier than Monday, Oct. 14, on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Europa Clipper’s elongated, looping orbit around Jupiter will minimize the spacecraft’s exposure to intense radiation while allowing it to dive in for close passes by Europa. Using a formidable array of instruments for each of the mission’s 49 flybys, scientists will be able to “see” how thick the moon’s icy shell is and gain a deeper understanding of the vast ocean beneath. They’ll inventory material on the surface that might have come up from below, search for the fingerprints of organic compounds that form life’s building blocks, and sample any gases ejected from the moon for evidence of habitability. Mission scientists will analyze the results, probing beneath the moon’s frozen shell for signs of a water world capable of supporting life. This artist’s concept (not to scale) depicts what Europa’s internal structure could look like: an outer shell of ice, perhaps with plumes of material venting from beneath the surface; a deep, global layer of liquid water; and a rocky interior, potentially with hydrothermal vents on the seafloor.NASA/JPL-Caltech “It’s important to us to paint a picture of what that alien ocean is like — the kind of chemistry or even biochemistry that could be happening there,” said Morgan Cable, an astrobiologist and member of the Europa Clipper science team at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission. Ice Investigation Central to that work is hunting for the types of salts, ices, and organic material that make up the key ingredients of a habitable world. That’s where an imager called MISE (Mapping Imaging Spectrometer for Europa) comes in. Operating in the infrared, the spacecraft’s MISE divides reflected light into various wavelengths to identify the corresponding atoms and molecules. The mission will also try to locate potential hot spots near Europa’s surface, where plumes could bring deep ocean material closer to the surface, using an instrument called E-THEMIS (Europa Thermal Emission Imaging System), which also operates in the infrared. Europa Clipper Press Kit Capturing sharply detailed pictures of Europa’s surface with both a narrow and a wide-image camera is the task of the EIS (Europa Imaging System). “The EIS imagers will give us incredibly high-resolution images to understand how Europa’s surface evolved and is continuing to change,” Cable said. Gases and Grains NASA’s Cassini mission spotted a giant plume of water vapor erupting from multiple jets near the south pole of Saturn’s ice-covered moon Enceladus. Europa may also emit misty plumes of water, pulled from its ocean or reservoirs in its shell. Europa Clipper’s instrument called Europa-UVS (Europa Ultraviolet Spectrograph) will search for plumes and can study any material that might be venting into space. Whether or not Europa has plumes, the spacecraft carries two instruments to analyze the small amount of gas and dust particles ejected from the moon’s surface by impacts with micrometeorites and high-energy particles: MASPEX (MAss SPectrometer for Planetary EXploration/Europa) and SUDA (SUrface Dust Analyzer) will capture the tiny pieces of material ejected from the surface, turning them into charged particles to reveal their composition. “The spacecraft will study gas and grains coming off Europa by sticking out its tongue and tasting those grains, breathing in those gases,” said Cable. Inside and Out The mission will look at Europa’s external and internal structure in various ways, too, because both have far-reaching implications for the moon’s habitability. To gain insights into the ice shell’s thickness and the ocean’s existence, along with its depth and salinity, the mission will measure the moon’s induced magnetic field with the ECM (Europa Clipper Magnetometer) and combine that data with measurements of electrical currents from charged particles flowing around Europa — data provided by PIMS (Plasma Instrument for Magnetic Sounding). In addition, scientists will look for details on everything from the presence of the ocean to the structure and topography of the ice using REASON (Radar for Europa Assessment and Sounding to Near-surface), which will peer up to 18 miles (29 kilometers) into the shell — itself a potentially habitable environment. Measuring the changes that Europa’s gravity causes in radio signals should help nail down ice thickness and ocean depth. “Non-icy materials on the surface could get moved into deep interior pockets of briny water within the icy shell,” said Steve Vance, an astrobiologist and geophysicist who also is a member of the Europa Clipper science team at JPL. “Some might be large enough to be considered lakes, or at least ponds.” Using the data gathered to inform extensive computer modeling of Europa’s interior structure also could reveal the ocean’s composition and allow estimates of its temperature profile, Vance said. Whatever conditions are discovered, the findings will open a new chapter in the search for life beyond Earth. “It’s almost certain Europa Clipper will raise as many questions or more than it answers — a whole different class than the ones we’ve been thinking of for the last 25 years,” Vance said. More About Europa Clipper Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology.

NASA canvases the areas impacted by Hurricane Milton using cloud-penetrating L-band radar providing responders insight into flooding across Florida.NASA In the wake of Hurricane Milton, NASA is deploying resources to support Federal Emergency Management Agency (FEMA) and state emergency management agencies to aid their response effort including satellite and aerial data collection. The agency’s Disasters Response Coordination System and Airborne Science Program are began conducting flights Friday to provide emergency responders with better insight into flooding, damage in Florida, and debris. “After the devastating impact from hurricanes Helene and Milton, NASA immediately sprang into action,” said Karen St. Germain, director, Earth Sciences Division at NASA Headquarters in Washington. “Whether it is through observations from space or from airplanes, NASA is ready to assist communities affected by severe storms. We are working together with our federal and state partners to provide a better understanding of what is happening on the ground, in real time. NASA’s Disasters Response Coordination System was designed with the goal of delivering trusted, actionable Earth science information, where and when people need it, to enable effective response when these events strike.” NASA’s Uninhabited Aerial Synthetic Aperture Radar Vehicle (UAVSAR) instrument is gathering rapid wide area L-Band synthetic aperture radar data shared directly with FEMA and other organizations. Flights are coordinated directly with FEMA to augment their existing satellite and aerial data collection. Since Hurricane Milton struck, persistent cloud cover over the State of Florida has made it challenging to obtain optical satellite observations of conditions in the region. Synthetic aperture radar instruments, such as those aboard UAVSAR, can see through the clouds to observe changes on the ground. This provides much-needed observations of flood inundation across communities in Florida, as well as the extent of inland river flooding and resource deployment. The Disaster Response Coordination System has been working closely with FEMA and state emergency management agencies to aid response efforts as Hurricane Milton approached and impacted Florida. The team is actively sharing resources with other agency partners, the state of Florida, and disaster response non-profit organizations. NASA continues to determine the needs of its partners and is sharing maps and data on the NASA Disasters Mapping Portal as they become available. Hurricane Milton caused significant wind, flooding, power outages, and damage across central Florida, from Sarasota and Tampa to Palm Springs and the Space Coast. Impacts are currently being assessed alongside lifesaving operations and emergency repairs. The Disasters Response Coordination System is collaborating directly with FEMA, the State of Florida Geospatial Information Office, U.S. Geological Survey, NOAA (National Oceanic and Atmospheric Administration), and the American Red Cross. The Disasters Response Coordination System is also sharing any available Earth observation data with NASA’s Kennedy Space Center emergency managers to support their damage assessment process. By using tools like NASA’s Black Marble, and updating daily with differential analysis done to highlight areas with extended power outages, the agency provides FEMA, states, and non-profits the opportunity to distribute temporary generators, life-sustaining resources, and damage assessments. The UAVSAR flights are being conducted with support from NASA’s Disasters Program, NASA’s Earth Action Program, and NASA’s Research and Analysis Program, and are being managed by NASA’s Armstrong Flight Research Center in Edwards, California, a NASA’s Jet Propulsion Laboratory in Southern and California, and the California Institute of Technology.

The right front wheel is parked on top of a rock, which altered the science team’s plan for the day. This image was taken by the Front Hazard Avoidance Camera (Front Hazcam) aboard Curiosity on sol 4328 — Martian day 4,328 of the Mars Science Laboratory mission — on Oct. 9, 2024, at 02:30:55 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Oct. 9, 2024 Curiosity is continuing to make good progress downhill along the western edge of the Gediz Vallis channel, allowing us to take another look from a different perspective at this area we’ve spent many months exploring. The drive from Monday’s plan executed as expected, positioning us about 30 meters (about 98 feet) north of our last location. Unfortunately, the rover parked with its right front wheel atop an unstable-looking rock, so we decided to keep the arm stowed rather than risk having the wheel slip with the arm unstowed. As a consequence, our plan today is all remote sensing, kicking off with a LIBS activity on a bedrock target “Sapphire Lake” and long distance RMI mosaics of “Pinnacle Ridge,” which avid readers may remember was a focus of an imaging campaign while we were still in the channel. Mastcam gets its turn on both Sapphire Lake and Pinnacle Ridge, as well as a Mastcam-exclusive target, “Wuksachi,” to document some rover-disturbed regolith and a wheel-scuffed rock surface. This plan’s drive is also in the first sol, which will hopefully bring us nearly 40 meters (about 131 feet) further north, closer to our eventual exit from Gediz Vallis. The first sol also sees a small collection of environmental science observations, including Navcam images to monitor dust and sand on the rover deck as well as a Navcam movie looking out over the northern horizon to look for clouds. We haven’t been seeing many clouds lately, but we are rapidly approaching the end of the current Mars Year, and the end of the dusty season. (The new year, numbered 38, begins Nov. 12; a Martian year is much longer than one on Earth, taking 687 Earth days to orbit the Sun.) Though the cloudy season won’t really pick up steam until February, the “noctilucent cloud season” will be taking place in December and January, which has produced some spectacular images in the past. Today’s plan also features an “UltraSPENDI,” or “Shunt Prevention ENV Navcam Drop-In.” This activity takes 18 cloud movies and dust devil movies over three hours and serves to prevent the rover’s batteries from remaining fully charged for an extended period of time, which would hurt their long-term health. The second sol of this plan is pretty simple, featuring a Mastcam tau to measure the amount of dust in the atmosphere, a ChemCam AEGIS activity, some more Navcam deck monitoring, and a 360-degree Navcam survey for dust devils around the rover. As always, REMS, RAD, and DAN will be continuing with their usual activities.

29 Min Read The Next Full Moon is a Supermoon, and the Hunter’s Moon A supermoon rises behind the U.S. Capitol, on March 9, 2020, in Washington. Credits: NASA/Joel Kowsky The Next Full Moon is a Supermoon; the Hunter’s Moon; the Travel Moon, the Dying Grass Moon, or the Sanguine or Blood Moon; the start of Sukkoth; Sharad Purnima, Kumara Purnima, Kojagari Purnima, Navanna Purnima Kojagrat Purnima, or Kaumudi Purnima; the end of Vassa and Pavarana; the Thadingyut Festival Moon; the end of the Phaung Daw U Pagoda Festival; and Vap Poya. The next full Moon will be Thursday morning, Oct. 17, 2024, at 7:26 a.m. EDT. This will be late Wednesday night for the International Date Line West time zone and early Friday morning from New Zealand Time eastwards to the International Date Line. The Moon will appear full for about three days around this time, from Tuesday evening through Friday morning. This will be the third of four consecutive supermoons (and the brightest by a tiny margin). As the full Moon after the Harvest Moon, this will be the Hunter’s Moon. The earliest written use of the term “Hunter’s Moon” identified in the Oxford English Dictionary is from 1710. According to the Farmer’s Almanac, with the leaves falling and the deer fattened, it is time to hunt. Since the harvesters have reaped the fields, hunters can easily see the animals that have come out to glean (and the foxes that have come out to prey upon them). The Maine Farmer’s Almanac first published Native American names for the full Moons in the 1930s. Over time these names have become widely known and used. According to this almanac, as the full Moon in October the Algonquin tribes in what is now the northeastern United States called this the Travel Moon, the Dying Grass Moon, or the Sanguine or Blood Moon. Some sources indicate that the Dying Grass, Sanguine, and Blood Moon names are related to the turning of the leaves and dying back of plants with the start of fall. Others indicate that the names Sanguine and Blood Moon are associated with hunting to prepare for winter. I have read that the name “Travel Moon” comes from observing the migration of birds and other animals preparing for the winter. I don’t know, but this name may also refer to the season when the more northern tribes would move down from the mountains for the winter. For example, both the Iroquois and Algonquin would hunt in the Adirondack Mountains during the summertime but leave in fall to avoid the harsh mountain winters. As the full Moon in the Hebrew month of Tishrei, this full Moon falls near the start of Sukkoth, a 7-day holiday starting on the 15th day of the month. Sukkoth is also known as the Feast of Tabernacles or the Feast of the Ingathering. Sukkoth honors both the sheltering of the People of Israel during the 40 years in the wilderness in the Book of Leviticus as well as an ancient harvest festival in the Book of Exodus. Sukkot is named for the sukkah (booths or huts) traditionally built for the occasion that represent the temporary huts in which Israelites lived after escaping from Egypt. Families symbolically invite ancestors to share meals in the sukkah and spend as much time as possible there throughout the week. This year Sukkoth starts at sunset on October 16 and ends at sunset on October 23. See https://en.wikipedia.org/wiki/Sukkot for more information. For Hindus, this is Sharad Purnima, also known as Kumara Purnima, Kojagari Purnima, Navanna Purnima Kojagrat Purnima, or Kaumudi Purnima. This is a harvest festival celebrated in a variety of ways. See https://en.wikipedia.org/wiki/Sharad_Purnima for more information. For Buddhists, this Moon marks the end of Vassa, the three-month period of fasting for monks tied to the monsoons (Vassa is sometimes given the English names “Rains Retreat” or “Buddhist Lent”). There are numerous festivals and holy days associated with this Moon at the end of Vassa. Many Buddhists observe the holy day Pavarana on this day. In Myanmar, this full Moon corresponds with the three-day Thadingyut Festival of Lights, also known as the Lighting Festival of Myanmar. Also in Myanmar, this full Moon is near the end of the Phaung Daw U Pagoda Festival. This festival began on the first Waxing Moon day of the month of Thadingyut and will end a few days past this full Moon. In Sri Lanka, this is Vap Poya, which is followed (usually within the lunar month) by the Kathina festival, during which people give gifts to the monks, particularly new robes (so this lunar month is sometimes called the Month of Robes). In many traditional Moon-based calendars the full Moons fall on or near the middle of each month. This full Moon is near the middle of the ninth month of the Chinese year of the Dragon and Rabi’ al-Thani, also called Rabiʽ al-Akhir, the fourth month of the Islamic year. As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the full Moon. Enjoy this harvest season, remember your ancestors, and consider camping out with your family. Here’s wishing you safe travels! Summary of Key Celestial Events Here are more celestial events between now and the full Moon after next (with specific times and angles based on the location of NASA Headquarters in Washington, D.C.): As Autumn continues the daily periods of sunlight continue shortening. On Thursday, Oct. 17, (the day of the full Moon), morning twilight will begin at 6:22 a.m. EDT, sunrise will be at 7:20 a.m., solar noon will be at 12:53 p.m. when the Sun will reach its maximum altitude of 41.5 degrees, sunset will be at 6:26 p.m., and evening twilight will end at 7:24 p.m.. By Friday, Nov. 15, (the day of the full Moon after next), we will have switched from Daylight Saving to Standard Time. Morning twilight will begin at 5:51 a.m. EST, sunrise will be at 6:51 AM, solar noon will be at 11:53 a.m. when the Sun will reach its maximum altitude of 32.4 degrees, sunset will be at 4:54 p.m., and evening twilight will end at 5:55 p.m. This should be a good season for Saturn viewing, especially through a backyard telescope. Saturn was at its closest and brightest the night of September 7. It will be shifting west each evening, making it higher in the sky and friendlier for evening viewing (particularly for children with earlier bedtimes). Through a telescope you should be able to see Saturn’s bright moon Titan and its rings. The rings are appearing thinner and will be edge-on to the Earth by early 2025. We won’t get the “classic” view of Saturn with its rings again until 2026. Comets Two comets might be visible during this lunar cycle. For both of these comets I recommend paying attention to the news and checking out local astronomy websites, as we should have better forecasts of how these comets are behaving as we get closer to the opportunities for prime viewing. Particularly for the newly discovered Comet C/2024 S1 (ATLAS), others (with newer information and better modeling tools) should be able to provide better guidance on when and where to look. Comet C/2023 A3 (Tsuchinshan-ATLAS) has already survived its close pass by the Sun and will be its closest to the Earth on October 12 (five days before the full Moon). After its closest approach it will be in the evening sky as twilight ends. If it continues on its current brightness curve it should be visible with binoculars and (under good conditions) with the unaided eye for at least a few evenings after the 12th, dimming as it moves away from the Sun and the Earth. On October 12, as evening twilight ends (at 7:31 p.m. EDT) the comet will be 4 degrees above the western horizon to the right of Venus (at an estimated visual magnitude of 2.9). As twilight ends on October 13 it will be 10 degrees above the western horizon (magnitude 3), 12 degrees on October 14 (magnitude 3.2), 16 degrees on October 15 (magnitude 3.3), etc. Current brightness curves predict it will dim to magnitude 6.2 by the end of October (nearing the edge of visibility with the unaided eye under dark and clear conditions). Comet C/2024 S1 (ATLAS) was discovered recently. It’s gotten a lot of attention because if it doesn’t break up as it approaches the Sun, it may become bright enough to see during the daytime. However, I want to avoid raising unrealistic expectations. From the information I’ve been able to find so far, I expect that at night this comet will only be visible with binoculars or a telescope, as its path will not bring it very close to the Earth. For the Washington, D.C. area (and similar latitudes) this comet will be above the horizon before morning twilight begins from now to October 21 as the comet falls towards the Sun. If it doesn’t break into pieces too small to see around closest approach, it should also be visible (with binoculars or a telescope) from November 2 to December 19 as the comet speeds away from the Sun. However, it is a sungrazing comet and will be passing just a few solar radii from the surface of the Sun. This is so close that the sunlight will be more than 14,000 times brighter than at Earth. Sunlight this intense may cause it to break up and evaporate. But if it remains intact, based on the estimates I have while writing this, the comet will be bright enough to see during the daylight for about an hour or two around closest approach. One brightness model estimates this comet will be brighter than magnitude -5 from 7:12 a.m. to 8:06 a.m. EDT. Based on this timing, Africa, Europe, and South America are best situated to see this daylight comet. From the East Coast of North America the comet at its brightest will be to the lower left of the Sun just after sunrise, which means we will be viewing it through more air, increasing the chance of interference from scattered sunlight and clouds. To look for this comet during the short period when it is very close to the Sun, find out for your location which side of the Sun the comet will be on, then find something to block the Sun (e.g., a house or building, etc., the farther away the better) so you can look for the comet without staring at the Sun. Be careful and plan ahead, as it may be difficult to find a location that has both a clear view to the right part of the east-southeastern horizon and a large overhanging object to block the Sun while allowing you to see to the lower left of the Sun. I strongly recommend AGAINST using binoculars or a telescope because accidentally using high powered lenses to focus intense sunlight into your eyes is a blindingly bad idea. If you are interested, here is some more background on Comet C/2024 S1 (ATLAS). Otherwise, skip this paragraph. This comet was discovered on Sept. 27, 2024, by one of the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescopes in Hawaii. This comet’s orbit suggests it is part of a family of comets called Kreutz sungrazers that pass very close to the Sun. These comets are thought to be fragments of a large sungrazing comet, the Great Comet of 1106, that broke up as it swung around the Sun 918 years ago. This 1106 comet might itself be a fragment of an even larger sungrazing comet, possibly the Great Comet of 371 BC (also known as Aristotle’s Comet). This comet was so bright it cast shadows at night like the full Moon. Several other members of this comet family have been great comets, including the Great Comet of 1843 and the Great Comet of 1882. The most recent great comet from this family was Comet Ikeya–Seki in 1965. Since its launch in 1995, the Solar and Heliospheric Observatory (SOHO) satellite has observed more than 4000 smaller Kreutz sungrazers, some only a few meters across, with none of these smaller comets surviving their close pass by the Sun. Meteor Showers Five meteor showers are predicted to peak during this lunar cycle. Three meteor showers peak between October 18 and 24 when the light of the waning Moon will interfere, the most significant being the Orionids peaking on October 21. While the Orionids tend to be brighter than average and to peak at about 20 meteors per hour (under ideal conditions), the light of the waning gibbous Moon will make these harder to see this year, especially from our light-polluted urban areas. Two minor meteor showers will peak in early November. These showers are the Southern Taurids (peaking at 7 meteors per hour on November 5) and the Northern Taurids (peaking at 5 meteors per hour on November 12). These showers overlap to produce their highest combined rate around November 5, but this rate is low enough that seeing these meteors from urban locations will be difficult. Evening Sky Highlights On the evening of Thursday, Oct. 17, 2024 (the evening of the full Moon), as twilight ends (at 7:24 p.m. EDT), the rising Moon will be 9 degrees above the eastern horizon. Saturn will be 27 degrees above the southeastern horizon. Bright Venus will be 6 degrees above the west-southwestern horizon. Comet C/2023 A3 (Tsuchinshan-ATLAS) will be to the upper right of Venus at 22 degrees above the western horizon (at a visual magnitude of 3.7 if it continues to follow its current brightness curve). The bright star closest to overhead will be Deneb at 80 degrees above the northeastern horizon. Deneb (visual magnitude 1.3) is the 19th brightest star in our night sky and is the brightest star in the constellation Cygnus the swan. Deneb is one of the three bright stars of the “Summer Triangle” (along with Vega and Altair). Deneb is about 20 times more massive than our Sun but has used up its hydrogen, becoming a blue-white supergiant about 200 times the diameter of the Sun. If Deneb were where our Sun is, it would extend to about the orbit of the Earth. Deneb is about 2,600 light years from us. As this lunar cycle progresses, Saturn and the background of stars will appear to shift westward each evening (as the Earth moves around the Sun). Bright Venus will shift to the left along the southwestern horizon in the opposite direction as the stars, passing above the bright star Antares (they will appear 3 degrees apart at their closest on October 25). October 21 will be the first evening the planet Mercury will be above the west-southwestern horizon 30 minutes after sunset (an estimate of when it will first be visible in the glow of dusk). The waxing Moon will pass by Antares on November 3, Venus on November 4, and Saturn on November 10. November 11 will be when Mercury will first appear above the horizon as twilight ends. By the evening of Friday, November 15 (the evening of the full Moon after next), as twilight ends at 5:55 p.m. EST, the rising Moon will be 14 degrees above the east-northeastern horizon with the Pleiades star cluster 5 degrees to the lower left. The brightest planet in the sky will be Venus at 12 degrees above the southwestern horizon. Next in brightness will be Mercury at less than a degree above the west-southwestern horizon. Saturn will be 38 degrees above the south-southeastern horizon. Comet C/2023 A3 (Tsuchinshan-ATLAS) will be 39 degrees above the west-southwestern horizon, with its current brightness curve predicting it will have faded to magnitude 8, too faint to see with the unaided eye. The bright star closest to overhead will still be Deneb at 79 degrees above the northwestern horizon. Morning Sky Highlights On the morning of Thursday, October 17, 2024 (the morning of the full Moon), as twilight begins at 6:22 a.m. EDT, the setting Moon will be 11 degrees above the western horizon. The brightest planet in the sky will be Jupiter at 63 degrees above the west-southwestern horizon. Mars will be at 72 degrees above the south-southeastern horizon. Comet C/2024 S1 (ATLAS) will be 6 degrees above the east-southeastern horizon but will likely be too dim to be seen without a telescope (current projection, magnitude 12.7). The bright star appearing closest to overhead will be Pollux, the 17th brightest star in our night sky and the brighter of the twin stars in the constellation Gemini, at 75 degrees above the southeastern horizon. Pollux is an orange tinted star about 34 lightyears from Earth. It is not quite twice the mass of our Sun but about 9 times the diameter and 33 times the brightness. As this lunar cycle progresses, Jupiter, Mars, and the background of stars will appear to shift westward each evening. Comet C/2024 S1 (ATLAS), visible with binoculars or a telescope, will brighten but shift lower as it races towards the Sun, with October 21 the last morning it will be above the horizon as morning twilight begins (estimated magnitude of 11.2). The waning Moon will pass by the Pleiades star cluster on October 19, Jupiter on October 21, Mars and Pollux on October 23, Regulus on October 26, and Spica on October 31. Comet C/2024 S1 (ATLAS) will pass its closest to the Sun on the morning of October 28 (when, if the sky is very clear, it might be bright enough to see in the daylight for an hour or so around 7:39 a.m.). If this comet survives its close pass by the Sun, it may reemerge in the morning sky. November 2 will be the first morning it will be above the horizon as morning twilight begins (with an estimated magnitude of 10.5, visible with binoculars or a telescope). By the morning of Friday, November 15 (the morning of the full Moon after next), as twilight begins (at 5:51 a.m. EST), the setting full Moon will be 7 degrees above the west-northwestern horizon. The brightest planet in the sky will be Jupiter at 35 degrees above the western horizon. Mars will be at 68 degrees above the southwestern horizon. Comet C/2024 S1 (ATLAS) will be 13 degrees above the southeastern horizon (estimated magnitude 14.2). The bright star appearing closest to overhead will still be Pollux at 69 degrees above the west-southwestern horizon (higher than Mars by about a half degree). Detailed Daily Guide .Here for your reference is a day-by-day listing of celestial events between now and the full Moon on October 17, 2024. The times and angles are based on the location of NASA Headquarters in Washington, D.C, and some of these details may differ for where you are (I use parentheses to indicate times specific to the D.C. area). If your latitude is significantly different than 39 degrees north (and especially for my Southern Hemisphere readers), I recommend using an astronomy app or a star-watching guide from a local observatory, news outlet, or astronomy club. Saturday morning, October 12: At 11:10 a.m. EDT, Comet C/2023 A3 (Tsuchinshan-ATLAS) will be at its closest to Earth. Although it will be on the horizon as evening twilight ends the evening before (Friday), it may be hard to see. Our first chance to see it above the horizon as evening twilight ends (at 7:31 PM) will likely be Saturday evening, when the comet will be 4 degrees above the western horizon, similar in altitude and to the right of Venus. As of September 28 this comet is still following a brightness curve that predicts it to be quite bright near closest approach and remain visible to unaided human eyes (under clear dark sky conditions) through the end of October. How bright the comet will be and how quickly it actually dims will depend upon the gas and dust it is giving off, which can vary quickly and unpredictably, but it should be an impressive show in the evenings after October 12. The comet will likely dim as it moves away from the Earth, but also appear higher in the sky and set later each evening, giving us more time and darker skies to look for it. As evening twilight ends on October 13 it will be 10 degrees above the western horizon, 12 degrees on October 14, 16 degrees on October 15, etc. Current brightness curves predict it will still be around magnitude 6 by the end of October (still visible to the unaided eye under good conditions). Monday evening, October 14: The planet Saturn will appear near the waxing gibbous Moon. As evening twilight ends (at 7:28 p.m. EDT) Saturn will be 4 degrees to the upper right. The Moon will reach its highest for the night about 3.5 hours later (at 10:53 p.m.) with Saturn 5 degrees to the lower right. The pair will continue to separate, with Saturn setting first 5 hours after that (at 4:09 a.m.). For parts of Southern Asia and Africa the Moon will block Saturn from view. Wednesday evening, October 16: At 8:57 p.m. EDT (CSG 8:47), the Moon will be at perigee, its closest to the Earth for this orbit. As mentioned above, the full Moon will be Thursday morning, Oct. 17, at 7:26 a.m. EDT. This will be late Wednesday night for the International Date Line West time zone and early Friday morning from New Zealand Time eastwards to the International Date Line. This will be the third of four consecutive supermoons (and the brightest by a tiny margin). The Moon will appear full for about 3 days around this time, from Tuesday evening through Friday morning. Saturday night into Sunday morning, October 19 to 20: The Pleiades star cluster will appear near the waning gibbous Moon. At moonrise (7:42 p.m. EDT) on the east-northeastern horizon the Pleiades will be 3 degrees to the upper right. By the time the Moon reaches its highest for the night at 3:28 a.m., the Pleiades will be 7 degrees to the lower right. Sunday night into Monday morning, October 20 to 21: The planet Jupiter will appear near the waning gibbous Moon. As Jupiter rises on the east-northeastern horizon at 9:08 p.m. EDT, it will be 6 degrees to the lower right of the Moon. As the Moon reaches its highest in the sky at 4:29 a.m., Jupiter will be 6 degrees below the Moon, and it will be to the lower left by the time morning twilight begins at 6:26 a.m. As mentioned above, the Orionid meteor shower will peak the early morning of Monday, October 21. Conditions are not good as moonlight will interfere with seeing these meteors, but if you happen to be out keep an eye on the sky, as you might see a meteor or two. For the Washington DC area and similar latitudes, Monday morning, October 21: This will be the last morning Comet C/2024 S1 (ATLAS), visible with binoculars or a telescope (estimated magnitude 11.2), will be above the horizon as morning twilight begins (at 6:27 AM EDT) as it rushes towards its close passage by the Sun a week later. Monday evening, October 21: This will be the first evening the planet Mercury will be above the west-southwestern horizon 30 minutes after sunset (an estimate of when it will start being visible in the glow of dusk). Tuesday night into Wednesday morning, October 22 to 23: The waning gibbous Moon, the bright star Pollux, and the planet Mars will form a triangle in the night sky. As Pollux rises on the northeastern horizon at 11 p.m. EDT, it will be 8 degrees to the lower left of the Moon. Mars will rise below the Moon 30 minutes later at 11:30 p.m. As the Moon reaches its highest for the night and morning twilight begins at 6:28 a.m., Pollux will be 4 degrees to the upper left and Mars will be 7 degrees to the lower left of the Moon. Thursday morning, October 24: The waning Moon will appear half-full as it reaches its last quarter at 4:03 a.m. EDT. If you find you are having trouble waking up in late October and early November, the dark mornings may be the reason (or at least a plausible excuse). Since 2007 when Congress moved the start of Daylight Saving Time from the end of October to the beginning of November, the latest sunrises of the year have been in late October and early November. In 2024, for the Washington, D.C. area and similar latitudes, the time of sunrise (in EDT) from Thursday, October 24 to Saturday, November 2 will be later than the latest sunrise of winter at 7:27 a.m. EST on January 5. In the evening sky during this lunar cycle the bright planet Venus will be shifting to the upper left along the southwestern horizon in the opposite direction as the background of stars. Friday, October 25: This will be when Venus and the bright star Antares will pass at their closest, with Antares 3 degrees to the lower left of Venus. Saturday morning, October 26: The bright star Regulus will appear below the waning crescent Moon. As Regulus rises on the east-northeastern horizon at 2:15 a.m. EDT, it will be 5 degrees below the Moon. Morning twilight will begin more than 4 hours later at 6:31 a.m. with Regulus 4 degrees to the lower right of the Moon. Monday morning, October 28: At about 7:39 a.m. EDT, Comet C/2024 S1 (ATLAS) will pass its closest to the Sun. If the sky is very clear, it might be bright enough to see in the daylight for an hour or so around closest approach. For the Washington, D.C. area, closest approach will only be 7 minutes after sunrise, so our only chance of seeing this is if the sky on the east-southeastern horizon is unusually clear. The comet will be to the lower left of the Sun, and since the tail points away from the Sun, it may be hidden by the horizon until the comet rises higher in the sky. Europe, Africa, and South America are better positioned to look for this comet near the Sun. Be careful and plan ahead, as it may be difficult to find a location that has both a clear view to the right part of the east-southeastern horizon and a large overhanging object to block the Sun while allowing you to see to the lower left of the Sun. Pay attention to the news as the predictions may change, but the brightness predictions I have as of writing this are that this comet will be brighter than magnitude -5 until 8:06 a.m. (when the Sun will be 5.6 degrees above the horizon). Magnitude -4 is generally considered the brightness limit for visibility of an object during the day, and the comet is predicted to be above this magnitude until 8:39 AM, but because it will be close to the Sun it is hard to say what the actual visibility limit will be, as the glare near the Sun depends on atmospheric conditions and can be quite bright. Tuesday, October 29: At 6:51 p.m. EDT, the Moon will be at apogee, its farthest from the Earth for this orbit. Thursday morning, October 31: You might be able to see the thin, waxing crescent Moon low on the east-southeastern horizon 3.5 degrees to the lower left of the bright star Spica. You will need to look for them in the glow of dawn, as the Moon will rise at 6:43 a.m. EDT 7 minutes after twilight begins at 6:36 a.m. Thursday, October 31, is Halloween: We currently divide the year into four seasons based upon the solstices and equinoxes, with winter beginning on the winter solstice in December. This approximates winter as the quarter of the year with the coldest temperatures. Much of pre-Christian northern Europe celebrated “cross-quarter days” halfway between the solstices and equinoxes, and divided the seasons on these days. Using this older definition, winter was the quarter of the year with the shortest daily periods of daylight, with autumn ending and winter beginning on Samhain, traditionally celebrated on October 31st or November 1st (the middle of our fall). Our Halloween customs are thought to have come from these earlier celebrations of fall’s end and winter’s start. Friday morning, November 1, at 8:47 AM EDT: This will be the new Moon, when the Moon passes between the Earth and the Sun and will not be visible from the Earth. This new Moon is considered the darkest night of the Hindu lunisolar calendar. Diwali or Divali, also known as Dipawali or Deepavali, is an important five or six day festival of lights centered on this new Moon, celebrated by Hindus and other faiths including Jains, Sikhs, and Newar Buddhists. The name comes from the row (avali) of clay lamps (deepa) celebrants light to symbolize the inner light that protects from spiritual darkness. Lakshmi Puja or Kali Puja, venerating the goddess of prosperity, Lakshmi, is the central day of the festival (November 1 this year). It is a public holiday in many countries with large Hindu, Sikh, and/or Jain populations, including Fiji, Guyana, India, Malaysia, Mauritius, Myanmar, Nepal, Pakistan, Singapore, Sri Lanka, Suriname, and Trinidad and Tobago. The day of or the day after the New Moon: This marks the start of the new month for most lunisolar calendars. The tenth month of the Chinese year of the Dragon starts on Friday, November 1. Sundown on Friday, November 1, marks the start of Marcheshvan in the Hebrew calendar, a name often shortened to Cheshvan or Heshvan. If Comet C/2024 S1 (ATLAS) survives its close pass by the Sun, Saturday, November 2, will be the first morning it will be above the horizon as morning twilight begins at 6:38 a.m. EDT, appearing with an estimated magnitude of 10.5 (only visible with binoculars or a telescope). Because of Daylight Saving Time, Saturday morning, November 2, will be the latest sunrise of the year. Morning twilight will begin at 6:38 a.m. EDT, sunrise will be at 7:37 a.m., solar noon will be at 12:51 p.m. when the Sun will reach its maximum altitude of 35.1 degrees, sunset will be at 6:06 p.m., and evening twilight will end at 7:05 p.m. In the Islamic calendar the months traditionally start with the first sighting of the waxing crescent Moon. Many Muslim communities now follow the Umm al-Qura Calendar of Saudi Arabia, which uses astronomical calculations to start months in a more predictable way. Using this calendar, sundown on Saturday, November 2, will probably mark the beginning of Jumādā al-ʾŪlā. Early on Sunday morning, November 3: We “Fall Back” from 1:59 a.m. EDT to 1 a.m. EST. While most of us will be gaining an hour of sleep, if you want to do something for 2 hours but are only supposed to do it for one, consider doing it for the “clock hour” from 1 a.m. EDT to 2 a.m. EST. Be careful though, as about twice as many accidents tend to happen during this “clock hour” compared to other mornings of the year! Regardless, on Sunday morning you will need to reset any clocks that didn’t reset themselves! On Sunday, twilight will begin at 5:39 a.m. EST, sunrise will be at 6:38 a.m., solar noon will be at 11:51 a.m. when the Sun will reach its maximum altitude of 35.8 degrees, sunset will be at 5:05 p.m., and evening twilight will end at 6:04 p.m. It may be difficult to see, but on Sunday evening, November 3, the bright star Antares will appear 2 degrees above the thin, waxing crescent Moon. You will need to look for the Moon in the glow of dusk as it will set on the southwestern horizon just 1 minute after evening twilight ends (at 6:04 p.m. EST). Monday evening, November 4: The bright planet Venus will appear 4 degrees to the upper right of the thin, waxing crescent Moon. The Moon will be 6 degrees above the southwestern horizon as evening twilight ends at 6:03 p.m. EST, and will set first 46 minutes later at 6:49 p.m. Tuesday morning, November 5: Two minor meteor showers, the Southern Taurids (peaking at 7 meteors per hour on November 5) and the Northern Taurids (peaking at 5 meteors per hour on November 12), overlap to produce their highest combined rate. Although the light of the waxing crescent Moon will not interfere, even this combined rate will be low enough to make seeing these meteors from urban areas difficult due to light pollution. Still, if you are out after midnight and the sky is clear, you might see a meteor or two. Early Saturday morning, November 9: The Moon will appear half-full as it reaches its first quarter at 12:56 a.m. EST. In the evenings during much of this lunar cycle, the planet Mercury will be shifting to the upper left along the southwestern horizon, moving in the opposite direction from the background of stars. On Saturday and Sunday evenings, November 9 and 10, Mercury and the bright star Antares will pass their closest, less than 2 degrees apart, with Antares to the lower left of Mercury. You will need to look low on the southwestern horizon while dusk is in the sky, as they both will have set by the time evening twilight ends. Saturday evening into early Sunday morning, November 9 to 10: The planet Saturn will appear near the waxing gibbous Moon. As evening twilight ends at 5:58 p.m. EST, Saturn will be 2 degrees to the upper left. The Moon will reach its highest point for the night about 1 hour 45 minutes later at 7:43 p.m., with Saturn 1 degree to the upper left. For the Washington, D.C. area, Saturn will be at its closest, about 0.1 degree to the upper right of the Moon, at about 9:55 p.m. (times and angles will differ for different locations). For the southern tip if Florida and parts of the Caribbean, Central America, and Northwestern South America, the Moon will block Saturn from view. The Moon will continue passing by Saturn, with Saturn setting first on the western horizon a little less than 3.5 hours later at 1:19 a.m. Monday evening, November 11: This will be the first evening that the planet Mercury will be above the west-southwestern horizon as evening twilight ends at 5:57 p.m. EST. Thursday morning, November 14: At 6:18 EST, the Moon will be at perigee, its closest to the Earth for this orbit. The full Moon after next will be Friday afternoon, November 15, 2024 at 4:29 PM EST. This will be early Saturday morning from Kamchatka and Fiji Time eastwards to the International Date Line. This will be the last of four consecutive supermoons. The Pleiades star cluster will appear near the full Moon. The Moon will appear full for about three days around this time, from a few hours before sunrise Thursday morning into a few hours before sunrise Sunday morning. View the full article

In honor of Hispanic Heritage Month, we recognize Hispanic astronauts who have flown in space. The table below lists these individuals of various nationalities who have made significant contributions to their space programs. The first Hispanic astronauts completed short flights to a Soviet space station and aboard the space shuttle. In the past 23 years, many more have completed flights to the International Space Station and contributed to its assembly, operations, and research activities. Table of Hispanic astronauts who have flown in space. Arnaldo Tamayo Méndez of Cuba holds the title of the first person of Hispanic heritage to fly in space. He spent eight days aboard the Salyut-6 space station in September 1980 as part of the Soviet Union’s Interkosmos program to fly cosmonauts from friendly socialist countries. The first Hispanic to fly on the space shuttle, Payload Specialist Rodolfo Neri Vela of Mexico, also introduced tortillas to astronauts’ on board menus during his flight on STS-61B in November 1985. Tortillas continue to be a staple on the space station today, for everything from breakfast tacos, to burgers, sandwiches, and pizzas. Selected as an astronaut in 1980, Costa Rican-born Franklin R. Chang-Díaz holds the honor as the first Hispanic American in space. He flew in space a record-tying seven times, including one visit to the Russian space station Mir and one to the International Space Station. Left: Portrait of Cuban cosmonaut Arnaldo Tamayo Méndez. Middle: Mexican payload specialist Rodolfo Neri Vela enjoys a trend-setting tortilla during the STS-61B mission. Right: Portrait of NASA astronaut Franklin R. Chang-Díaz. Franklin R. Chang-Díaz Chang-Díaz’s first flight, STS-61C aboard space shuttle Columbia, took place in January 1986, a six-day flight to deploy a communications satellite and to remotely observe Halley’s comet. The crew included two future NASA administrators, NASA astronauts Charles F. Bolden and U.S. Senator (D-FL) C. William “Bill” Nelson. The flight landed just 10 days before the tragic loss of space shuttle Challenger. His next mission, STS 34 aboard Atlantis, in October 1989 saw the deployment of the Galileo spacecraft to explore Jupiter with an orbiter and an atmospheric probe. Chang-Díaz launched on his third mission, STS 46 in July 1992, an eight-day flight aboard Atlantis to test fly the first Tethered Satellite System (TSS-1). Left: Franklin R. Chang-Díaz, center, the first Hispanic American astronaut, with his fellow STS-61C crew members. Middle: Chang-Díaz, center, and the STS-34 crew. Right: Chang-Díaz, upper right, with the STS-46 crew. Chang-Díaz returned to space for his fourth mission in January 1994 aboard Discovery. The eight-day STS-60 flight comprised the first flight in the Shuttle-Mir program, with Russian cosmonaut Sergey K. Krikalev a member of the crew. Chang-Díaz launched on his fifth flight in February 1996, the 16-day STS-75 mission aboard Columbia to refly the TSS. On his sixth mission in June 1998, the STS-91 crew docked Discovery with the Russian space station Mir and returned astronaut Andrew S.W. Thomas to earth, the final Shuttle-Mir mission. Left: Franklin R. Chang-Díaz, lower left, with the STS-60 crew. Middle: Chang-Díaz, left, with his STS-75 crew mates. Right: Chang-Díaz, with the STS-91 and Mir 25 crews. During his record-tying seventh trip into space, Chang-Díaz made his only visit to the space station. The main goals of Endeavour’s STS-111 mission in June 2002 included the exchange of the Expedition 4 and 5 crews and the resupply of the station using the Leonardo Multi-Purpose Logistics Module (MPLM). Two new research facilities rode in the MPLM, the fifth Expedite the Processing of Experiments to the Space Station (EXPRESS) rack and the Microgravity Sciences Glovebox. Chang-Díaz completed three spacewalks with his fellow mission specialist, French astronaut Philippe Perrin, to install the Mobile Base System portion of the Canadarm2’s remote manipulator system and perform maintenance tasks on the station.

On his first mission in June 1991, he served as the pilot of Columbia on the STS-40 Spacelab Life Sciences-1 mission, a nine-day flight dedicated to investigating the responses of the human body to weightlessness. He also served as a test subject for several of the experiments. During his second mission in April 1994, Gutierrez served as the commander of STS-59, the Space Radar Laboratory-1 flight, an 11-day mission aboard Endeavour. The payload included a synthetic aperture imaging radar. Left: NASA astronaut Sidney M. Gutierrez, center, with his STS-40 crew mates. Right: Gutierrez, center, with the STS-59 crew. Ellen Ochoa Selected as the first female Hispanic astronaut in 1990, Ellen Ochoa completed four spaceflights and then served as the first Hispanic director of NASA’s Johnson Space Center in Houston. On her first mission in April 1993, she served as a mission specialist on the nine-day STS-56 flight, the second Atmospheric Laboratory for Applications and Science (ATLAS) mission aboard Discovery. An accomplished flautist, she played her flute during the flight. On her second flight, STS-66 in March 1994, Ochoa flew aboard Atlantis and operated the experiments of the ATLAS-3 payload during the 11-day mission. Left: Ellen Ochoa, top left, and the rest of the STS-56 crew. Middle: Ochoa plays the flute on Discovery’s flight deck. Right: Ochoa, top left, and the rest of the STS-66 crew. Ochoa holds the distinction as the first Hispanic astronaut to visit the space station, making her first visit in May 1999 as a mission specialist aboard Discovery’s 10-day STS-96 mission. The goals of the mission – only the second shuttle flight to the station that, at the time, comprised only two modules – included the transfer of two tons of logistics to the station, launched inside a Spacehab double module, and the delivery of the Russian Strela cargo crane.

Right: Ochoa, bottom, with fellow STS-96 crewmembers Julie Payette of the Canadian Space Agency in the Zarya module. Ochoa returned to a much-enlarged space station aboard space shuttle Atlantis in April 2002 during the STS-110 mission that delivered the 13-ton S0 truss – the center segment section to which future truss segments were later attached. Ochoa operated the Space Station Remote Manipulator System (SSRMS), also known as Canadarm2, to lift the S0 truss from the shuttle’s payload bay and attach it atop the Destiny module. The S0 truss also contained the Mobile Transporter to allow the SSRMS to translate up and down the trusses. Ochoa was named as JSC’s deputy director in 2007, then as JSC’s first Hispanic director in 2013. She served in that position until her retirement from NASA in 2018.

On his first spaceflight, he served as a mission specialist on STS-73, the second flight of the United States Microgravity Laboratory. The 16-day mission aboard Columbia in October 1995 included 37 investigations supported by 11 facilities, with the seven-member crew working around the clock in two shifts in a Spacelab module. Left: Michael E. Lopez-Alegria, center, with the rest of the STS-73 crew inside the Spacelab module. Right: Lopez-Alegria working on biological experiment in the Spacelab module. Lopez-Alegria served as a mission specialist on STS-92 during his first visit to the space station. He and his six crewmates launched aboard Discovery in October 2000, the 100th launch of the program and the last to visit an unoccupied station. At the time, the station comprised just three modules. During the mission, the STS-92 crew installed the Z1 truss atop the Unity module, four Control Moment Gyros, and the third Pressurized Mating Adaptor. The Z1 truss enabled the addition of solar arrays and radiators on the subsequent assembly flight and also contained high-rate communications equipment including the first Space-to-Ground antenna. Lopez-Alegria participated in two of the mission’s four spacewalks with Peter J. “Jeff” Wisoff to complete the assembly tasks. During their last spacewalk, the two conducted the first flight evaluation at the station of the Simplified Aid for EVA Rescue (SAFER), a propulsive backpack to be used by astronauts should they become detached from the spacecraft. The STS-92 crew left the station ready for its first inhabitants, and indeed less than two weeks later, the first Expedition crew arrived to begin permanent residency in low Earth orbit. Left: NASA astronaut Michael E. Lopez-Alegria working outside the space station during STS-92. Middle: Lopez-Alegria, left, tests the Simplified Aid for EVA Rescue as fellow NASA astronaut Peter J. “Jeff” Wisoff looks on. Right: The space station as seen from Discovery shortly after undocking, showing the Z1 Truss with the Space-to-Ground Antenna at top and the third Pressurized Mating Adaptor at bottom. For his third flight into space, Lopez-Alegria returned to the station in November 2002 during the STS-113 mission, the facility now permanently occupied and having grown significantly in the intervening two years. The primary tasks for the STS-113 crew included adding the P1 truss on the station’s port side, installing the Crew Equipment Translation Aid (CETA) cart, and assisting in the exchange between the Expedition 5 and 6 crews. Lopez-Alegria and fellow STS-113 mission specialist John B. Harrington conducted three spacewalks to complete the installation of the P1 truss and the CETA cart. After STS-113, assembly of the station came to a temporary halt following the Feb. 1, 2003, Columbia accident, and the subsequent grounding of the space shuttle fleet. Flights did not resume until September 2006. Left: NASA astronaut Michael E. Lopez-Alegria during the first STS-113 spacewalk. Middle: Lopez-Alegria, second from right in the middle row, posing in the Destiny module with his STS-113 crewmates, as well as the Expedition 5 and 6 crews. Right: The space station as seen by the departing STS-113 crew, with the newly installed P1 truss visible at right. Lopez-Alegria returned to the space station again shortly after assembly resumed. For his fourth spaceflight, he launched aboard Soyuz TMA9 in September 2006, from the Baikonur Cosmodrome in Kazakhstan,. Mikhail V. Tyurin of Roscosmos accompanied him during the 215-day mission, to that time the longest space station expedition, was Mikhail V. Tyurin of Roscosmos. European Space Agency (ESA) astronaut Thomas A. Reiter, onboard the station since July 2006, became part of the Expedition 14 crew. As Commander of Expedition 14, Lopez-Alegria oversaw one of the most complex set of activities in the assembly of the station – the reconfiguration of its power and cooling systems. A week before his arrival, the STS-115 mission had delivered the second set of solar arrays to the station as part of the P3/P4 truss segment, positioning them outboard of the P1 segment. As part of the reconfiguration, the port side P6 array mounted atop the Z1 truss needed to be retracted to prevent interference with the rotation of the new arrays, a task that was completed during the visiting STS-116 mission in December that also added the P5 short spacer to the port side truss. That mission brought NASA astronaut Sunita L. “Suni” Williams to the station as a new addition to Expedition 14 and returned Reiter back to Earth. During Expedition 14, Lopez-Alegria took part in five spacewalks, two in Orlan spacesuits with Tyurin to conduct work on the outside of the Russian segment and three in American spacesuits, with Williams to reconfigure the cooling system of the U.S. segment. He accumulated a total of 67 hours and 40 minutes over 10 spacewalks – still the record among American astronauts. Lopez-Alegria also conducted a variety of scientific experiments.

In April 2022, he commanded the Ax-1 mission, the first commercial astronaut mission to the space station. He and his three crewmates spent 17 days aboard, conducting a variety of experiments. Lopez-Alegria returned to space as commander of the Ax-3 mission in January 2024. He and his three multi-national crewmates spent 22 days aboard the space station conducting numerous experiments. Across his six missions, Lopez-Alegria accumulated a total of 297 days in space. Left: Axiom Space astronaut Michael E. Lopez-Alegria floats into the space station during the Ax-1 mission.

On his first spaceflight in May 1997, he served as a mission specialist aboard STS-84, the sixth Shuttle-Mir docking mission. During the nine-day flight, the crew resupplied the Mir space station, brought NASA astronaut C. Michael Foale to the Russian outpost, and returned Jerry M. Linenger to Earth. Left: Carlos I. Noriega sets up an experiment during the STS-84 mission. Middle: Noriega working on an experiment in the Spacecab module. Right: The 10 members of the STS-84 and Mir resident crew, with Noriega at upper right. In December 2000, Noriega launched on his second mission, aboard Endeavour with his four crewmates on STS-97, their primary goal to install the P6 truss segment with the first set of solar arrays and radiators atop the Z1 truss. STS-97 marked the first time a shuttle visited the station after its occupancy began, but given the busy spacewalk schedule, the hatches between the two vehicles were only open for 24 hours. Noriega and fellow mission specialist Joseph R. Tanner conducted three spacewalks to complete the P6 installation and other assembly tasks. The new solar arrays generated enough power for the arrival of the U.S. laboratory module Destiny early in 2001 and the start of intensive research aboard the space station.

Pedro Duque The European Space Agency (ESA) selected Pedro Duque, born in Madrid, Spain, as an astronaut in 1992. Four years later, he joined NASA’s astronaut class of 1996 in training and two years later certified as a mission specialist. His first launch into space took place in October 1998 on Discovery’s STS-95 mission, the nine-day flight that saw astronaut John H. Glenn’s return to space. Duque returned to space in October 2003 aboard Soyuz TMA3, conducting experiments aboard the space station as part of his Cervantes visiting mission. He returned to Earth 10 days later aboard Soyuz TMA2. Left: Spanish astronaut Pedro Duque, lower left, representing the European Space Agency, with his STS-95 crewmates. Middle: Duque conducting an experiment in the Microgravity Science Glovebox aboard the space station. Right: Duque, center, with his Expedition 7 and 8 crewmates. Marcos C. Pontes The Brazilian Space Agency selected Marcos C. Pontes as an astronaut in 1998. He trained with NASA’s astronaut class of 1998 and certified as a mission specialist two years later. Pontes made his one and only spaceflight in March 2006 aboard Soyuz TMA8, carrying out eight experiments. He returned to Earth 10 days later aboard Soyuz TMA7. Left: Brazilian astronaut Marcos Pontes, center at rear, with his Expedition 12 and 13 crewmates. Middle: Pontes works on an experiment in the Destiny Laboratory Module. Right: Pontes at work on an experiment in the Russian Zvezda module. John D. “Danny” Olivas Selected as a member of NASA’s Astronaut Class of 1998, John D. “Danny” Olivas visited the space station on two occasions as a shuttle mission specialist. His first visit took place aboard Atlantis during the STS-117 mission in June 2007. During the flight, Olivas and fellow mission specialist James F. Reilly conducted two of the four spacewalks to install the S3/S4 truss segment that included the third set of solar arrays. To prevent interfering with the rotation of the new arrays, the crew retracted the starboard P6 array mounted atop the Z1 truss. The STS-117 mission also served as a crew exchange flight, with NASA astronaut Clayton C. Anderson replacing Suni Williams as a member of Expedition 15. Left: NASA astronaut John D. “Danny” Olivas during an STS-117 spacewalk working on the S3/S4 truss installation. Middle: Olivas, back row at right, with the STS-117 and Expedition 15 crews. Right: The space station as seen by the departing STS-117 crew, showing the new set of starboard solar arrays at right. On his return to the station, Olivas found it a bit more crowded – three months earlier, the permanent crew aboard the station had expanded from three to six. He and his crewmates launched aboard Discovery on the STS-128 mission in August 2009. The shuttle’s payload bay contained the Leonardo MPLM bringing supplies to help maintain a 6-person crew on the space station, including three systems racks: a crew quarters, an Air Revitalization System rack, and the Combined Operational Load Bearing External Resistance Treadmill (COLBERT) for crew exercise – as well as three research racks – the Fluid Integrated Rack , the Materials Science Research Rack, and the second Minus Eighty-degree Laboratory Freezer for ISS (MELFI). Olivas participated in three spacewalks to replace the Ammonia Tank Assembly on the P1 truss and to retrieve two experiments from the European Columbus module’s External Payload Facility. STS-128 also completed the final shuttle-based crew exchange, with NASA astronauts Nicole P. Stott and Timothy L. Kopra exchanging places as Expedition 20 crewmembers.

Right: Olivas, at center, with the STS-128 and Expedition 20 crews. George D. Zamka Selected as a NASA astronaut in 1998, George D. Zamka completed his first space flight as pilot on Discovery’s STS-120 mission. Launching in October 2007, Zamka and his crewmates brought the Harmony Node 2 module to the station, temporarily berthing it on the Unity Node 1’s port side until the Expedition 16 crew relocated it to Destiny’s forward hatch. In its final location, Harmony enabled the later installation of the European and Japanese elements. The crew also relocated the P6 truss segment from atop Z1 to the outboard port truss. During the redeployment of the P6 solar arrays, one of the arrays developed a tear that required repair using a cufflink-like device to sew up the gap in the panel. STS-120 also conducted a crew exchange, with NASA astronauts Daniel M. Tani and Clay Anderson exchanging places as members of Expedition 16. As the STS-120 pilot, Zamka completed the undocking from the station and the departure fly-around maneuver. Left: NASA astronaut George D. Zamka holding the cufflink device used to repair the torn solar array. Middle: Zamka, lower right, with the STS-120 and Expedition 16 crews. Right: The space station as seen from STS-120 departing, showing the newly delivered Harmony Node 2 module temporarily berthed at the Unity Node 1 and the relocated and redeployed P6 truss segment and solar arrays at left. When he returned to the orbiting lab in February 2010, Zamka did so as commander of space shuttle Endeavour’s STS-130 mission. After guiding the shuttle to a successful docking with the station, Zamka and his crewmates, along with the Expedition 22 crew, installed the Tranquility Node 3 module to Unity’s port side and activated the new element. The new module provided accommodations for life support and habitation facilities for the station’s six-person crew. The crew removed the Cupola from its launch position at the end of Tranquility and relocated it to the module’s Earth-facing port. The Cupola’s six trapezoidal and one circular center window provide crews not only visibility for approaching visiting vehicles, but also spectacular views of their home planet passing by below.

Joseph M. “Joe” Acaba Joseph M. “Joe” Acaba was selected in 2004 as part of NASA’s Educator Astronaut Program and qualified as a mission specialist. His first flight into space was aboard STS-119 in March 2009. Discovery brought up the S6 final truss segment with the fourth and final set of solar arrays, bringing the U.S. segment of the station’s useable power generating capability between 42 and 60 kilowatts. Acaba completed two of the mission’s three spacewalks, one with fellow mission specialist Steven R. Swanson and the other with fellow educator-astronaut and mission specialist Richard R. “Ricky” Arnold. During the STS-119 mission, Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) replaced NASA astronaut Sandra H. Magnus as a member of the Expedition 18 crew.

Hernández Selected in 2004 as a NASA astronaut, José M. Hernández made his single visit to the space station during the STS-128 mission. Launched aboard space shuttle Discovery in August 2009, Hernández operated both the shuttle and station robotic arms to move the Leonardo MPLM back and forth and translate astronauts during the mission’s three spacewalks. He participated in the transfer and installation of the three systems racks and the three research racks aboard the orbiting laboratory. STS-128 also completed the final shuttle-based crew exchange, with Stott replacing Kopra as an Expedition 20 crew member. In collaboration with Amazon Studios, NASA is helping chronicle Hernández’ life and career through the film “A Million Miles Away,” telling the story of his journey from migrant farmer to NASA space explorer.

NASA/Matthew Dominick NASA astronaut Matthew Dominick captured this timelapse photo of Comet C/2023 A3 (Tsuchinshan-ATLAS) International Space Station as it orbited 272 miles above the South Pacific Ocean southeast of New Zealand just before sunrise on Sept. 28, 2024. At the time, the comet was about 44 million miles away from Earth. Though the comet is very old, it was just discovered in 2023, when it approached the inner solar system on its highly elliptical orbit for the first time in documented human history. Beginning in mid-October 2024, Comet C/2023 A3 (Tsuchinshan-ATLAS) will become visible low in the west following sunset. If the comet’s tail is well-illuminated by sunlight, it could be visible to the unaided eye. Oct. 14-24 is the best time to observe, using binoculars or a small telescope. The comet hails from the Oort Cloud, which scientists think is a giant spherical shell surrounding our solar system. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt and may contain billions, or even trillions, of objects. Image Credit: NASA/Matthew Dominick View the full article

2 min read ESA/NASA’s SOHO Spies Bright Comet Making Debut in Evening Sky The tail of comet C/2023 A3 Tsuchinshan-ATLAS spanned the view of the Solar and Heliospheric Observatory (SOHO) on Oct. 10, 2024. ESA/NASA The ESA (European Space Agency) and NASA Solar and Heliospheric Observatory (SOHO) has captured images of the second-brightest comet to ever pass through its field of view during the spacecraft’s nearly 29-year career. The bright comet is C/2023 A3 Tsuchinshan-ATLAS, which has been garnering a lot of attention from skywatchers recently, displaying a long, dusty tail in pre-dawn skies throughout late September and early October. (Comet McNaught, viewed in 2007, holds the record as the brightest comet SOHO has seen.) Between Oct. 7 and 11, the comet blazed through the view of SOHO’s LASCO (Large Angle and Spectrometric Coronagraph Experiment) instrument, which uses a disk to block out the bright light of the Sun so it’s easier to see details and objects near the Sun. This image, taken by SOHO on Oct. 10, 2024, shows the comet and its bright tail streaming from the upper left to the right. Mercury appears as a bright dot on the left. After crossing through SOHO’s field of view, the comet will begin putting on an evening show for skywatchers around the world just after sunset starting Saturday, Oct. 12. Each day throughout October, the comet will gradually rise higher and higher in the western sky as it moves farther away from the Sun. But as it does, it will become fainter and fainter. Eagle-eyed skywatchers may be able to spot it with the naked eye for a few days, but after that, observers will likely need binoculars or a telescope to see it as it grows fainter. Even if you are unable to spot this comet yourself, you can help SOHO search for others.

Exploring beyond the Earth’s surface exposes humans to conditions that can impact blood pressure, bone density, immune health, and much more. With this in mind, two NASA inventors joined forces 20 years ago to create a way to someday monitor astronaut heart health on long-duration spaceflight missions. This technology is now being used to monitor the health of patients with heart failure on Earth through a commercial product that is slated to launch in late 2024. NASA inventors Dr. Rainee Simons, senior microwave communications engineer, and Dr. Félix Miranda, deputy chief of the Communications and Intelligent Systems Division, applied their expertise in radio frequency integrated circuits and antennas to create a miniature implantable sensor system to keep track of astronaut health in space. The technology, which was created at NASA’s Glenn Research Center in Cleveland with seed funds from the agency’s Technology Transfer Office, consists of a small bio-implanted sensor that can transmit a person’s health status from a sensor to a handheld device. The sensor is battery-less and wireless. “You’re able to insert the sensor and bring it up to the heart or the aorta like a stent – the same process as in a stent implant,” Simons said. “No major surgery is needed for implantation, and operating the external handheld device, by the patient, is simple and easy.” After Glenn patented the invention, Dr. Anthony Nunez, a heart surgeon, and Harry Rowland, a mechanical engineer, licensed the technology and founded a digital health medical technology company in 2007 called Endotronix, now an Edwards Lifesciences company. The company focuses on enabling proactive heart failure management with data-driven patient-to-physician solutions that detect dangers, based on the Glenn technology. The Endotronix primary monitoring system is called the Cordella Pulmonary Artery (PA) Sensor System. Dr. Nunez became aware of the technology while reading a technical journal that featured the concept, and he saw parallels that could be used in the medical technology industry. The concept has proven to be an aid for heart failure management through several clinical trials, and patients have experienced improvements in their quality of life. Based on the outcome of Endotronix’s clinical testing to demonstrate safety and effectiveness, in June 2024 the U.S. Food and Drug Administration granted premarket approval to the Cordella PA Sensor System. The system is meant to help clinicians remotely assess, treat, and manage heart failure in patients at home with the goal of reducing hospitalizations. “If you look at the statistics of how many people have congestive heart failure, high blood pressure… it’s a lot of people,” Miranda said. “To have the medical community saying we have a device that started from NASA’s intellectual property – and it could help people worldwide to be healthy, to enjoy life, to go about their business – is highly gratifying, and it’s very consistent with NASA’s mission to do work for the benefit of all.” Explore More 2 min read Controlled Propulsion for Gentle Landings A valve designed for NASA rover landings enables effective stage separations for commercial spaceflight Article 40 mins ago 2 min read Sail Along with NASA’s Solar Sail Tech Demo in Real-Time Simulation NASA invites the public to virtually sail along with the Advanced Composite Solar Sail System‘s space… Article 21 hours ago 4 min read Lunar Autonomy Mobility Pathfinder: An OTPS-Sponsored Workshop Article 1 day ago View the full article

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The controlled descent of the Mars Curiosity rover included the use of propulsion rockets pointing to the surface to allow a gentle landing. The engine, shown firing in this illustration of Perseverance and the sky crane landing system relied on a pyrovalve that released the rocket fuel.Credit: NASA /JPL-Caltech The Curiosity and Perseverance Mars rovers continue to provide a wealth of information about the Red Planet. This was made possible in part by the sky crane landing systems that safely lowered them to the planet’s surface. Their successful descent, managed by eight powerful engines, depended on one small part – a valve. The engines produced about 750 pounds of thrust each, so they required more fuel than a conventional valve could deliver, said Carl Guernsey, propulsion subsystem chief engineer for the Mars Sample Laboratory Mission. “With the engines pointing down, we throttle up and increase the thrust, so we slow down,” said Guernsey. “At a certain altitude above the surface, you hold at a constant velocity to collect more sensor data, and then proceed with the rest of the descent.” With only seconds for sensor data to identify the landing area and direct any last-minute diversion maneuvers, landing requires fuel available at the right time. To build the valve to help accomplish this task, NASA turned to a company that has provided the space program with reliable gas regulators since the 1950s. Through a series of mergers, by 2021, the original company, called Conax Florida, became part of Eaton based in Orchard Park, New York. Working under contract with NASA’s Jet Propulsion Laboratory in Southern California, the company developed a new one-time-use pyrovalve to sit between the hydrazine fuel tank and engines. The zero-leak valve was the largest ever made of its type at the time, at three-fourths of an inch. This one-time-use pyrovalve sat between the hydrazine fuel tank and the controlled-descent engines on the sky crane for the Curiosity and Perseverance Mars rovers. The zero-leak valve developed by Eaton also ensured no fuel was lost on the long flight to Mars.Credit: Eaton Corp. The Y-shaped pipe with a pair of leak-proof solid metal barriers prevented propellant from flowing. The valve contains a pyrotechnic charge that activates a piston called a flying ram, which shears off the barriers, allowing fuel to flow. But a problem arose during flight qualification testing. Sometimes the ram didn’t stay wedged in place at the bottom, posing a blockage risk. The solution the team came up with had never been tried before – magnets at the bottom of the valve. But the successful Perseverance landing in 2021 proved it works. The same valve is included in the Perseverance rover and now enables commercial rocket-stage separation in space.

“My mom had to leave school after 9th grade to support her family, but she always emphasized the importance of education. And with a lot of sacrifices, got us an encyclopedia in Spanish, ‘Enciclopedia de Las Ciencias’. By getting that encyclopedia for us, without knowing it, my mom was my first mentor because she introduced me to science. So that’s what helped fall in love with physics. “I was the first of many things. I was the only one in my whole class that decided to study physics at the University of Puerto Rico at Mayagüez. I was the first master student to do a thesis related to atmospheric physics. There was no atmospheric sciences and meteorology in Puerto Rico, I saw the need and potential, so I started the first student chapter of the American Meteorological Society in Puerto Rico. I was the first one to get a PhD in atmospheric physics from the program and there have been so many firsts since then. “I’m leading by example. I don’t want the people who look like me to experience what I experienced because I was alone many times. And there’s a saying that says you cannot be what you can’t see. “So, I’m not just doing science. I’m doing Science with Purpose, and my purpose is to be the voice for those who are underrepresented in science, open doors and opportunities and help them understand that they have a space in science.” – Dr. Yaíta Luna-Cruz, Program Executive, Earth Science Division, NASA Headquarters Image Credit: NASA/Keegan Barber Interviewer: NASA/Jessica Salani Lee esta historia en español aquí.

ESA/Hubble & NASA, F. Belfiore, J. Lee and the PHANGS-HST Team The sparkling scene depicted in this NASA/ESA Hubble Space Telescope image is of the spiral galaxy NGC 5248, located 42 million light-years from Earth in the constellation Boötes. It is also known as Caldwell 45. The Caldwell catalog holds visually interesting celestial objects that are not as commonly observed by amateur astronomers as the more famous Messier objects. NGC 5248 is one of the so-called ‘grand design’ spirals, with prominent spiral arms that reach from near the core out through the disk. It also has a faint bar structure at its center, between the inner ends of the spiral arms, which is not quite so obvious in this visible-light portrait from Hubble. Features like these which break the rotational symmetry of a galaxy have a huge influence on how matter moves through it, and eventually its evolution through time. They feed gas from a galaxy’s outer reaches to inner star-forming regions, and even to a galaxy’s central black hole where it can kick-start an active galactic nucleus. These flows of gas have shaped NGC 5248 in a big way; it has many bright ‘starburst regions’ of intense star formation spread across its disk, which a population of young stars dominates. The galaxy even has two very active, ring-shaped starburst regions around its nucleus, filled with young clusters of stars. These ‘nuclear rings’ are remarkable enough, but normally a nuclear ring tends to block gas from getting further into the core of a galaxy. NGC 5248 having a second ring inside the first is a marker of just how forceful its flows of matter and energy are! Because the galaxy is relatively nearby, its highly visible starburst regions make the galaxy a target for professional and amateur astronomers alike.

Unable to render the provided source NASA invites the public to virtually sail along with the Advanced Composite Solar Sail System‘s space journey using NASA’s “Eyes on the Solar System” visualization tool, a digital model of the solar system. This simulation shows the real-time positions of the planets, moons, and spacecraft – including NASA’s Advanced Composite Solar Sail System. Solar sails use the pressure of sunlight for propulsion, angling toward or away from the Sun so that photons bounce off the reflective sail to push a spacecraft. This eliminates the need for heavy propulsion systems and could enable longer duration and lower cost missions. The results from this technology demonstration – including the test of the sail’s composite boom system – will advance future space exploration to expand our understanding of our Sun and solar system. The Advanced Composite Solar Sail System, which launched in April 2024, and deployed its reflective sail in August, is currently orbiting approximately 600 miles (1,000 kilometers) above Earth and is frequently visible in the night sky to observers in the Northern Hemisphere. Fans of the spacecraft can look for the sail in the night sky using a new feature in the NASA mobile app. Visibility may be intermittent, and the spacecraft could appear at variable levels of brightness as it moves in orbit.
