6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) With one of its solar arrays deployed, NASA’s Lunar Trailblazer sits in a clean room at Lockheed Martin Space. The large silver grate attached to the spacecraft is the radiator for HVM³, one of two instruments that the mission will use to better understand the lunar water cycle.Lockheed Martin Space There’s water on the Moon, but scientists only have a general idea of where it is and what form it is in. A trailblazing NASA mission will get some answers. When NASA’s Lunar Trailblazer begins orbiting the Moon next year, it will help resolve an enduring mystery: Where is the Moon’s water? Scientists have seen signs suggesting it exists even where temperatures soar on the lunar surface, and there’s good reason to believe it can be found as surface ice in permanently shadowed craters, places that have not seen direct sunlight for billions of years. But, so far, there have been few definitive answers, and a full understanding of the nature of the Moon’s water cycle remains stubbornly out of reach. This is where Lunar Trailblazer comes in. Managed by NASA’s Jet Propulsion Laboratory and led by Caltech in Pasadena, California, the small satellite will map the Moon’s surface water in unprecedented detail to determine the water’s abundance, location, form, and how it changes over time. “Making high-resolution measurements of the type and amount of lunar water will help us understand the lunar water cycle, and it will provide clues to other questions, like how and when did Earth get its water,” said Bethany Ehlmann, principal investigator for Lunar Trailblazer at Caltech. “But understanding the inventory of lunar water is also important if we are to establish a sustained human and robotic presence on the Moon and beyond.” Future explorers could process lunar ice to create breathable oxygen or even fuel. And they could also conduct science. Using information from Lunar Trailblazer, future human or robotic scientific investigations could sample the ice for later study to determine where the water came from. For example, the presence of ammonia in ice samples may indicate the water came from comets; sulfur, on the other hand, could show that it was vented to the surface from the lunar interior when the Moon was young and volcanically active. This artist’s concept depicts NASA’s Lunar Trailblazer in lunar orbit about 60 miles (100 kilometers) from the surface of the Moon. The spacecraft weighs only 440 pounds (200 kilograms) and measures 11.5 feet (3.5 meters) wide when its solar panels are fully deployed.Lockheed Martin Space “In the future, scientists could analyze the ice in the interiors of permanently shadowed craters to learn more about the origins of water on the Moon,” said Rachel Klima, Lunar Trailblazer deputy principal investigator at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. “Like an ice core from a glacier on Earth can reveal the ancient history of our planet’s atmospheric composition, this pristine lunar ice could provide clues as to where that water came from and how and when it got there.” Understanding whether water molecules move freely across the surface of the Moon or are locked inside rock is also scientifically important. Water molecules could move from frosty “cold traps” to other locations throughout the lunar day. Frost heated by the Sun sublimates (turning from solid ice to a gas without going through a liquid phase), allowing the molecules to move as a gas to other cold locations, where they could form new frost as the Sun moves overhead. Knowing how water moves on the Moon could also lead to new insights into the water cycles on other airless bodies, such as asteroids Two Instruments, One Mission Two science instruments aboard the spacecraft will help unlock these secrets: the High-resolution Volatiles and Minerals Moon Mapper (HVM3) infrared spectrometer and the Lunar Thermal Mapper (LTM) infrared multispectral imager. Developed by JPL, HVM3 will detect and map the spectral fingerprints, or wavelengths of reflected sunlight, of minerals and the different forms of water on the lunar surface. The spectrometer can use faint reflected light from the walls of craters to see the floor of even permanently shadowed craters. The LTM instrument, which was built by the University of Oxford and funded by the UK Space Agency, will map the minerals and thermal properties of the same lunar landscape. Together they will create a picture of the abundance, location, and form of water while also tracking how its distribution changes over time. “The LTM instrument precisely maps the surface temperature of the Moon while the HVM3 instrument looks for the spectral signature of water molecules,” said Neil Bowles, instrument scientist for LTM at the University of Oxford. “Both instruments will allow us to understand how surface temperature affects water, improving our knowledge of the presence and distribution of these molecules on the Moon.” Weighing only 440 pounds (200 kilograms) and measuring 11.5 feet (3.5 meters) wide when its solar panels are fully deployed, Lunar Trailblazer will orbit the Moon about 60 miles (100 kilometers) from the surface. The mission was selected by NASA’s SIMPLEx (Small Innovative Missions for Planetary Exploration) program in 2019 and will hitch a ride on the same launch as the Intuitive Machines-2 delivery to the Moon through NASA’s Commercial Lunar Payload Services initiative. Lunar Trailblazer passed a critical operational readiness review in early October at Caltech after completing environmental testing in August at Lockheed Martin Space in Littleton, Colorado, where it was assembled. The orbiter and its science instruments are now being put through flight system software tests that simulate key aspects of launch, maneuvers, and the science mission while in orbit around the Moon. At the same time, the operations team led by IPAC at Caltech is conducting tests to simulate commanding, communication with NASA’s Deep Space Network, and navigation. More About Lunar Trailblazer Lunar Trailblazer is managed by JPL, and its science investigation and mission operations are led by Caltech with the mission operations center at IPAC.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Permafrost Tunnel north of Fairbanks, Alaska, was dug in the 1960s and is run by the U.S. Army’s Cold Regions Research and Engineering Laboratory. It is the site of much research into permafrost — ground that stays frozen throughout the year, for multiple years.NASA/Kate Ramsayer Earth’s far northern reaches have locked carbon underground for millennia. New research paints a picture of a landscape in change. A new study, co-authored by NASA scientists, details where and how greenhouse gases are escaping from the Earth’s vast northern permafrost region as the Arctic warms. The frozen soils encircling the Arctic from Alaska to Canada to Siberia store twice as much carbon as currently resides in the atmosphere — hundreds of billions of tons — and most of it has been buried for centuries. An international team, led by researchers at Stockholm University, found that from 2000 to 2020, carbon dioxide uptake by the land was largely offset by emissions from it. Overall, they concluded that the region has been a net contributor to global warming in recent decades in large part because of another greenhouse gas, methane, that is shorter-lived but traps significantly more heat per molecule than carbon dioxide. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Greenhouse gases shroud the globe in this animation showing data from 2021. Carbon dioxide is shown in orange; methane is shown in purple. Methane traps heat 28 times more effectively than carbon dioxide over a 100-year timescale. Wetlands are a significant source of such emissions.NASA’s Scientific Visualization Studio The findings reveal a landscape in flux, said Abhishek Chatterjee, a co-author and scientist at NASA’s Jet Propulsion Laboratory in Southern California. “We know that the permafrost region has captured and stored carbon for tens of thousands of years,” he said. “But what we are finding now is that climate-driven changes are tipping the balance toward permafrost being a net source of greenhouse gas emissions.” Carbon Stockpile Permafrost is ground that has been permanently frozen for anywhere from two years to hundreds of thousands of years. A core of it reveals thick layers of icy soils enriched with dead plant and animal matter that can be dated using radiocarbon and other techniques. When permafrost thaws and decomposes, microbes feed on this organic carbon, releasing some of it as greenhouse gases. Unlocking a fraction of the carbon stored in permafrost could further fuel climate change. Temperatures in the Arctic are already warming two to four times faster than the global average, and scientists are learning how thawing permafrost is shifting the region from being a net sink for greenhouse gases to becoming a net source of warming. They’ve tracked emissions using ground-based instruments, aircraft, and satellites. One such campaign, NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE), is focused on Alaska and western Canada. Yet locating and measuring emissions across the far northern fringes of Earth remains challenging. One obstacle is the vast scale and diversity of the environment, composed of evergreen forests, sprawling tundra, and waterways. This map, based on data provided by the National Snow and Ice Data Center, shows the extent of Arctic permafrost. The amount of permafrost underlying the surface ranges from continuous — in the coldest areas — to more isolated and sporadic patches.NASA Earth Observatory Cracks in the Sink The new study was undertaken as part of the Global Carbon Project’s RECCAP-2 effort, which brings together different science teams, tools, and datasets to assess regional carbon balances every few years. The authors followed the trail of three greenhouse gases — carbon dioxide, methane, and nitrous oxide — across 7 million square miles (18 million square kilometers) of permafrost terrain from 2000 to 2020. Researchers found the region, especially the forests, took up a fraction more carbon dioxide than it released. This uptake was largely offset by carbon dioxide emitted from lakes and rivers, as well as from fires that burned both forest and tundra. They also found that the region’s lakes and wetlands were strong sources of methane during those two decades. Their waterlogged soils are low in oxygen while containing large volumes of dead vegetation and animal matter — ripe conditions for hungry microbes. Compared to carbon dioxide, methane can drive significant climate warming in short timescales before breaking down relatively quickly. Methane’s lifespan in the atmosphere is about 10 years, whereas carbon dioxide can last hundreds of years. The findings suggest the net change in greenhouse gases helped warm the planet over the 20-year period. But over a 100-year period, emissions and absorptions would mostly cancel each other out. In other words, the region teeters from carbon source to weak sink. The authors noted that events such as extreme wildfires and heat waves are major sources of uncertainty when projecting into the future. Bottom Up, Top Down The scientists used two main strategies to tally greenhouse gas emissions from the region. “Bottom-up” methods estimate emissions from ground- and air-based measurements and ecosystem models. Top-down methods use atmospheric measurements taken directly from satellite sensors, including those on NASA’s Orbiting Carbon Observatory-2 (OCO-2) and JAXA’s (Japan Aerospace Exploration Agency)Greenhouse Gases Observing Satellite. Regarding near-term, 20-year, global warming potential, both scientific approaches aligned on the big picture but differed in magnitude: The bottom-up calculations indicated significantly more warming. “This study is one of the first where we are able to integrate different methods and datasets to put together this very comprehensive greenhouse gas budget into one report,” Chatterjee said. “It reveals a very complex picture.” News Media Contacts Jane J.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Kathy Clark (left) and Ryan D. Brown have both served as chairs of NASA Glenn Research Center’s Disability Awareness Advisory Group, which works to help provide individuals with disabilities equal opportunities in all aspects of employment.Credit: NASA/Jef Janis Kathy Clark started her career at NASA’s Glenn Research Center in Cleveland straight out of high school, and when offered either a job as an accountant or a job in training, the choice was crystal clear. “I started in training, I’ve stayed in training, and I’ll probably retire in training,” said Clark, now a human resources specialist and program manager of NASA Glenn’s mentoring program, Shaping Professionals and Relating Knowledge (SPARK). “I just love people.” Celebrating 41 years at NASA this October, Clark has long been an advocate for employees. For over 12 years, she served as chair of the center’s Disability Awareness Advisory Group (DAAG), which works to help provide individuals with disabilities equal opportunities in all aspects of employment. The group also strives to identify and eliminate workplace barriers, raise awareness, and ensure accessible facilities. After recently stepping down, Clark reflects on her legacy of creating change with the group and looks to the next generation of leadership, including longtime member and new chair Ryan D. Brown, to continue its important mission. “Don’t Let a Disability Stop You” Clark joined DAAG around 12 years into her career, after she was diagnosed with multiple sclerosis. She was later asked to serve as chair after she helped bring a traveling mural to the center that showcased Ohio artists with disabilities. During Clark’s time as chair, the group helped secure reserved parking spaces for employees with disabilities, instead of just relying on a first-come first-serve system for accessible spots. She recalls DAAG championing other facility issues, such as fixing a broken elevator and faulty door that presented challenges for folks with disabilities. The group has also worked with human resources to compile best practices for interviews, hosted various speakers, and offered a space for members to share about their disabilities. “I was honored to be the chair and just be there for the people and to try to make a difference, to let them know, if you need something, reach out,” Clark said. “Don’t let a disability stop you.” “I was honored to be the chair and just be there for the people and to try to make a difference, to let them know, if you need something, reach out." Kathy clark “Let’s Go Above and Beyond” When it was time to choose Clark’s successor, she said, another supportive and vocal member stood out: Brown. Thanks to an Ohio program for individuals with disabilities, Brown was placed at NASA as an intern in 2006, later completing a co-op that led to a full-time accounting position at the center, where he now works as a lead in the financial systems branch. More than one in four adults in the United States have some type of disability, according to the U.S. Centers for Disease Control and Prevention, and some are not always easy to see, Brown says. For instance, Brown has an invisible disability: a learning disability related to reading and writing. After connecting with a coworker early in his career who was a member of DAAG, Brown reached out to Clark to join. “Everyone has their challenges, regardless of if you have a disability or not, so making people comfortable talking about it and bringing it up is always good,” he said. “I think I’ve always liked speaking up for individuals and trying to spread that awareness, which has been great with DAAG.” Now the chair, Brown has supported the group in developing a job aid to help employees understand how to self-identify as having a disability. They’ve also recently organized awareness events to help other employees understand the experiences and challenges of individuals with disabilities. DAAG also continues to champion facility updates. For example, the group is currently working to get automatic door openers installed for bathrooms in buildings at the center where many employees gather. “Let’s try to go above and beyond and really make it easier on individuals,” Brown said. “Let’s try to go above and beyond and really make it easier on individuals." ryan D. brown “Make a Difference” Membership in the group is growing, and Clark looks forward to its future. “I could not have turned over the chair role to a better person than Ryan,” she said. Brown’s vision is to continue spreading the word that the group is available as a resource for employees, and for others throughout the center to be more aware of the experiences of individuals with disabilities. The work he does to help others inspires him every day, he says. “We’re here for individuals that don’t want to speak up, we’re here for individuals if they run into issues – they can always contact us,” Brown said. “It’s all about getting up there and trying to make a difference.” Explore More 4 min read Destacado de la NASA: Felipe Valdez, un ingeniero inspirador Article 4 days ago 3 min read Event Details Article 4 days ago 5 min read October Transformer of the Month: Nipa Phojanamongkolkij Article 6 days ago View the full article

Credit: NASA In an effort to grow new commercial markets that support the future of space exploration, scientific discovery, and aeronautics research, NASA is preparing to relaunch its Mentor-Protégé Program for contractors on Friday, Nov. 1. The program originally was launched to encourage NASA prime contractors, or mentors, to enter into agreements with eligible small businesses, or protégés. These agreements were created to enhance the protégés’ performance on NASA contracts and subcontracts, foster the establishment of long-term business relationships between small businesses and NASA prime contractors, and increase the overall number of small businesses that receive NASA contracts and subcontract awards. “The NASA Mentor-Protégé Program is a critical enabling tool that allows experienced companies to provide business developmental assistance to emerging firms,” said Dwight Deneal, assistant administrator for NASA’s Office of Small Business Programs (OSBP). “The program enables NASA to expand its industrial base of suppliers, as prime and subcontractors, to assist in executing the mission and programs throughout the agency.” The program’s relaunch follows an assessment of its policies and procedures by OSBP to ensure it continues to support NASA’s missions and addresses any supply chain gaps at an optimal level. To provide more information about the program and its relaunch, OSBP will host an online lunch and learn event on Thursday, Nov. 7, at 1:00 p.m. EST. The event is open to all current and potential mentors and protégés who want to learn more about changes in the program, qualifications to participate, and how to apply. “We are excited about rolling out the enhanced NASA Mentor-Protégé Program,” said David Brock, lead small business specialist for OSBP. “The program’s new focus will allow large businesses to mentor smaller firms in key areas that align with NASA’s mission and opportunities within the agency’s supply chain.” One key change expands eligibility to all small businesses, in addition to minority-serving institutions, including Historically Black Colleges and Universities, and Ability One entities. This expansion enables the program to support an inclusive environment for more small businesses and underserved communities to interact with NASA and its contractors. The program also will focus on engaging businesses within a select number of North American Industry Classifications System (NAICS) codes and specific industry sectors, such as research and development and aerospace manufacturing. These adjustments will allow the program to better support NASA’s long-term strategic goals and mission success. The program is designed to benefit both the mentor and the protégé by fostering productive networking and contract opportunities. In a mentor-protégé agreement, mentors build relationships with small businesses, developing a subcontracting base and accruing credit toward their small business subcontracting goals. In addition, protégés receive technical and developmental assistance while also gaining sole-source contracts from mentors and additional contracting opportunities. NASA is responsible for the administration and management of each agreement. The OSBP oversees the program and conducts semi-annual performance reviews to monitor progress and accomplishments made as a result of the mentor-protégé agreement. To apply to be a mentor, companies must be a current NASA prime contractor with an approved small business contracting plan. Companies also must be eligible for the receipt of government contracts and be categorized under certain NAICS codes. Potential protégés must certify as a small business within NAICS size standards.

The Rocky Mountains in Colorado, as seen from the International Space Station. Snowmelt from the mountainous western United States is an essential natural resource, making up as much as 75% of some states’ annual freshwater supply. Summer heat has significant effects in the mountainous regions of the western United States. Melted snow washes from snowy peaks into the rivers, reservoirs, and streams that supply millions of Americans with freshwater—as much as 75% of the annual freshwater supply for some states. But as climate change brings winter temperatures to new highs, these summer rushes of freshwater can sometimes slow to a trickle. “The runoff supports cities most people wouldn’t expect,” explained Chris Derksen, a glaciologist and Research Scientist with Environment and Climate Change Canada. “Big cities like San Francisco and Los Angeles get water from snowmelt.” To forecast snowmelt with greater accuracy, NASA’s Earth Science Technology Office (ESTO) and a team of researchers from the University of Massachusetts, Amherst, are developing SNOWWI, a dual-frequency synthetic aperture radar that could one day be the cornerstone of future missions dedicated to measuring snow mass on a global scale – something the science community lacks. SNOWWI aims to fill this technology gap. In January and March 2024, the SNOWWI research team passed a key milestone, flying their prototype for the first time aboard a small, twin-engine aircraft in Grand Mesa, Colorado, and gathering useful data on the area’s winter snowfields. “I’d say the big development is that we’ve gone from pieces of hardware in a lab to something that makes meaningful data,” explained Paul Siqueira, professor of engineering at the University of Massachusetts, Amherst, and principal investigator for SNOWWI. SNOWWI stands for Snow Water-equivalent Wide Swath Interferometer and Scatterometer. The instrument probes snowpack with two Ku-band radar signals: a high-frequency signal that interacts with individual snow grains, and a low-frequency signal that passes through the snowpack to the ground. The high-frequency signal gives researchers a clear look at the consistency of the snowpack, while the low-frequency signal helps researchers determine its total depth. “Having two frequencies allows us to better separate the influence of the snow microstructure from the influence of the snow depth,” said Derksen, who participated in the Grand Mesa field campaign. “One frequency is good, two frequencies are better.” The SNOWWI team in Grand Mesa, preparing to flight test their instrument. From an altitude of 4 kilometers (2.5 miles), SNOWWI can map 100 square kilometers (about 38 square miles) in just 30 minutes. As both of those scattered signals interact with the snowpack and bounce back towards the instrument, they lose energy. SNOWWI measures that lost energy, and researchers later correlate those losses to features within the snowpack, especially its depth, density, and mass. From an airborne platform with an altitude of 2.5 miles (4 kilometers), SNOWWI could map 40 square miles (100 square kilometers) of snowy terrain in just 30 minutes. From space, SNOWWI’s coverage would be even greater. Siqueira is working with Capella Space to develop a space-ready SNOWWI for satellite missions. But there’s still much work to be done before SNOWWI visits space. Siqueira plans to lead another field campaign, this time in the mountains of Idaho. Grand Mesa is relatively flat, and Siqueira wants to see how well SNOWWI can measure snowpack tucked in the folds of complex, asymmetrical terrain. For Derksen, who spends much of his time quantifying the freshwater content of snowpack in Canada, having a reliable database of global snowpack measurements would be game-changing. “Snowmelt is money. It has intrinsic economic value,” he said. “If you want your salmon to run in mountain streams in the spring, you must have snowmelt. But unlike other natural resources, at this time, we really can’t monitor it very well.” For information about opportunities to collaborate with NASA on novel, Earth-observing instruments, see ESTO’s catalog of open solicitations with its Instrument Incubator Program here.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Stephanie Dudley, Gateway’s mission integration and utilization manager, sits inside a high-fidelity HALO (Habitation and Logistics Outpost) mockup at NASA’s Johnson Space Center.NASA/Josh Valcarcel Stephanie Dudley sits at the intersection of human spaceflight and science for Gateway, humanity’s first lunar space station that will host astronauts and unique scientific investigations. Gateway’s mission integration and utilization manager, Dudley recently posed for this photo in a high-fidelity mockup of the space station’s HALO (Habitation and Logistics Outpost), where astronauts will live, conduct science, and prepare for missions to investigate the lunar South Pole region. Dudley works with NASA’s partner space agencies and academia to identify science opportunities on Gateway. HALO will host various science experiments, including the Heliophysics Environmental and Radiation Measurement Experiment Suite, led by NASA, and the Internal Dosimeter Array, led by ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency). The heliophysics experiment will fly on HALO’s exterior, and the dosimeter will be housed inside Gateway in a series of racks, mockups of which are shown to the right of Dudley in the image above. Both experiments will study solar and cosmic radiation to help the science community better understand how to protect astronauts and hardware during deep space travels to places like Mars. “We are building [Gateway] for a 15-year lifespan, but definitely hope that we go longer than that,” Dudley recently said on Houston We Have a Podcast. “And so that many years of scientific study in a place where humans have never worked and lived long-term, Gateway is going to allow us to do that.” Dudley pulls double duty as a deputy director for the Exploration Operations Office within NASA’s Moon to Mars Program, a role that connects her to Artemis science beyond Gateway, including science investigations on the Orion and Human Landing System spacecraft and lunar terrain vehicle. “My work…is helping to make sure that across all of the six [Artemis] programs, including Gateway, we’re all focusing on utilization in the same way,” Dudley said. Dudley’s team coordinates science payloads for Artemis II, the first mission to send humans to the Moon since 1972, and Artemis III, the first landing in the lunar South Pole region that is of keen interest to the global science community. Gateway’s HALO will launch with the space station’s Power and Propulsion Element ahead of the Artemis IV mission in 2028, the first lunar mission to include an orbiting space station. “Gateway sounds so science fiction, but it’s real,” Dudley recently said. “And we’re building it. And in a few years, it’s going to be around the Moon and that’s when the real work, the fun work in my opinion, is going to begin and science will never be the same.” Gateway is humanity’s first lunar space station as a central component of the Artemis campaign that will return humans to the Moon for scientific discovery and chart a path for the first human missions to Mars.

3 min read Sols 4345-4347: Contact Science is Back on the Table NASA’s Mars rover Curiosity acquired this image using its Right Navigation Camera on sol 4343 — Martian day 4,343 of the Mars Science Laboratory mission — on Oct. 24, 2024 at 15:26:28 UTC. NASA/JPL-Caltech Earth planning date: Friday, Oct. 25, 2024 The changes to the plan Wednesday, moving the drive a sol earlier, meant that we started off planning this morning about 18 meters (about 59 feet) farther along the western edge of Gediz Vallis and with all the data we needed for planning. This included the knowledge that once again one of Curiosity’s wheels was perched on a rock. Luckily, unlike on Wednesday, it was determined that it was safe to still go ahead with full contact science for this weekend. This consisted of two targets “Mount Brewer” and “Reef Lake,” two targets on the top and side of the same block. Aside from the contact science, Curiosity has three sols to fill with remote imaging. The first two sols include “targeted science,” which means all the imaging of specific targets in our current workspace. Then, after we drive away on the second sol, we fill the final sol of the plan with “untargeted science,” where we care less about knowing exactly where the rover is ahead of time. A lot of the environmental team’s (or ENV) activities fall under this umbrella, which is why our dedicated “ENV Science Block” (about 30 minutes of environmental activities one morning every weekend) tends to fall at the end of a weekend plan. But that’s getting ahead of myself. The weekend plan starts off with two ENV activities — a dust devil movie and a suprahorizon cloud movie. While cloud movies are almost always pointed in the same direction, our dust devil movie has to be specifically targeted. Recently we’ve been looking southeast toward a more sandy area (which you can see above), to see if we can catch dust lifting there. After those movies we hand the reins back over to the geology team (or GEO) for ChemCam observations of Reef Lake and “Poison Meadow.” Mastcam will follow this up with its own observations of Reef Lake and the AEGIS target from Wednesday’s plan. The rover gets some well-deserved rest before waking up for the contact science I talked about above, followed by a late evening Mastcam mosaic of “Fascination Turret,” a part of Gediz Vallis ridge that we’ve seen before. We’re driving away on the second sol, but before that we have about another hour of science. ChemCam and Mastcam both have observations of “Heaven Lake” and the upper Gediz Vallis ridge, and ENV has a line-of-sight observation, to see how much dust is in the crater, and a pre-drive deck monitoring image to see if any dust moves around on the rover deck due to either driving or wind. Curiosity gets a short nap before a further drive of about 25 meters (about 82 feet). The last sol of the weekend is a ChemCam special. AEGIS will autonomously choose a target for imaging, and then ChemCam has a passive sky observation to examine changing amounts of atmospheric gases. The weekend doesn’t end at midnight, though — we wake up in the morning for the promised morning ENV block, which we’ve filled with two cloud movies, another line-of-sight, and a tau observation to see how dusty the atmosphere is.

X-ray: NASA/CXC/SAO/J. Drake et al, IR: NASA/JPL-Caltech/Spitzer; Image Processing: NASA/CXC/SAO/N. Wolk Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets. A team of astronomers used NASA’s Chandra X-ray Observatory, in combination with ultraviolet, optical, and infrared data, to show where some of the most treacherous places in a star cluster may be, where planets’ chances to form are diminished. The target of the observations was Cygnus OB2, which is the nearest large cluster of stars to our Sun — at a distance of about 4,600 light-years. The cluster contains hundreds of massive stars as well as thousands of lower-mass stars. The team used long Chandra observations pointing at different regions of Cygnus OB2, and the resulting set of images were then stitched together into one large image. The deep Chandra observations mapped out the diffuse X-ray glow in between the stars, and they also provided an inventory of the young stars in the cluster. This inventory was combined with others using optical and infrared data to create the best census of young stars in the cluster. In this new composite image, the Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region. In these crowded stellar environments, copious amounts of high-energy radiation produced by stars and planets are present. Together, X-rays and intense ultraviolet light can have a devastating impact on planetary disks and systems in the process of forming. Planet-forming disks around stars naturally fade away over time. Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a wind. The latter process, known as “photoevaporation,” usually takes between 5 and 10 million years with average-sized stars before the disk disappears. If massive stars, which produce the most X-ray and ultraviolet radiation, are nearby, this process can be accelerated. The researchers using this data found clear evidence that planet-forming disks around stars indeed disappear much faster when they are close to massive stars producing a lot of high-energy radiation. The disks also disappear more quickly in regions where the stars are more closely packed together. For regions of Cygnus OB2 with less high-energy radiation and lower numbers of stars, the fraction of young stars with disks is about 40%. For regions with more high-energy radiation and higher numbers of stars, the fraction is about 18%. The strongest effect — meaning the worst place to be for a would-be planetary system — is within about 1.6 light-years of the most massive stars in the cluster. A separate study by the same team examined the properties of the diffuse X-ray emission in the cluster. They found that the higher-energy diffuse emission comes from areas where winds of gas blowing away from massive stars have collided with each other. This causes the gas to become hotter and produce X-rays. The less energetic emission probably comes from gas in the cluster colliding with gas surrounding the cluster. Two separate papers describing the Chandra data of Cygnus OB2 are available. The paper about the planetary danger zones, led by Mario Giuseppe Guarcello (National Institute for Astrophysics in Palermo, Italy), appeared in the November 2023 issue of the Astrophysical Journal Supplement Series, and is available here. The paper about the diffuse emission, led by Juan Facundo Albacete-Colombo (University of Rio Negro in Argentina) was published in the same issue of Astrophysical Journal Supplement, and is available here.

The center of the square image is dominated by purple haze. This haze represents diffuse X-ray emissions, and young stars, detected by the Chandra X-ray observatory. Surrounding the purple haze is a mottled, streaky, brick orange cloud. Another cloud resembling a tendril of grey smoke stretches from our lower left to the center of the image. These clouds represent relatively cool dust and gas observed by the Spitzer Space Telescope. Although the interwoven clouds cover most of the image, the thousands of stars within the cluster shine through. The lower-mass stars present as tiny specks of light. The massive stars gleam, some with long refraction spikes.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This enhanced-color mosaic was taken on Sept. 27 by the Perseverance rover while climbing the western wall of Jezero Crater. Many of the landmarks visited by the rover during its 3½-year exploration of Mars can be seen.NASA/JPL-Caltech/ASU/MSSS On its way up the side of Jezero Crater, the agency’s latest Red Planet off-roader peers all the way back to its landing site and scopes the path ahead. NASA’s Perseverance Mars rover is negotiating a steeply sloping route up Jezero Crater’s western wall with the aim of cresting the rim in early December. During the climb, the rover snapped not only a sweeping view of Jezero Crater’s interior, but also imagery of the tracks it left after some wheel slippage along the way. An annotated version of the mosaic captured by Perseverance highlights nearly 50 labeled points of interest across Jezero Crater, including the rover’s landing site. The 44 images that make up the mosaic were taken Sept. 27.NASA/JPL-Caltech/ASU/MSSS Stitched together from 44 frames acquired on Sept. 27, the 1,282nd Martian day of Perseverance’s mission, the image mosaic features many landmarks and Martian firsts that have made the rover’s 3½-year exploration of Jezero so memorable, including the rover’s landing site, the spot where it first found sedimentary rocks, the location of the first sample depot on another planet, and the final airfield for NASA’s Ingenuity Mars Helicopter. The rover captured the view near a location the team calls “Faraway Rock,” at about the halfway point in its climb up the crater wall. “The image not only shows our past and present, but also shows the biggest challenge to getting where we want to be in the future,” said Perseverance’s deputy project manager, Rick Welch of NASA’s Jet Propulsion Laboratory in Southern California. “If you look at the right side of the mosaic, you begin to get an idea what we’re dealing with. Mars didn’t want to make it easy for anyone to get to the top of this ridge.” Visible on the right side of the mosaic is a slope of about 20 degrees. While Perseverance has climbed 20-degree inclines before (both NASA’s Curiosity and Opportunity rovers had crested hills at least 10 degrees steeper), this is the first time it’s traveled that steep a grade on such a slippery surface. This animated orbital-map view shows the route NASA’s Perseverance Mars rover has taken since its February 2021 landing at Jezero Crater to July 2024, when it took its “Cheyava Falls” sample. As of October 2024, the rover has driven over 30 kilometers (18.65 miles), and has collected 24 samples of rock and regolith as well as one air sample. NASA/JPL-Caltech Soft, Fluffy During much of the climb, the rover has been driving over loosely packed dust and sand with a thin, brittle crust. On several days, Perseverance covered only about 50% of the distance it would have on a less slippery surface, and on one occasion, it covered just 20% of the planned route. “Mars rovers have driven over steeper terrain, and they’ve driven over more slippery terrain, but this is the first time one had to handle both — and on this scale,” said JPL’s Camden Miller, who was a rover planner, or “driver,” for Curiosity and now serves the same role on the Perseverance mission. “For every two steps forward Perseverance takes, we were taking at least one step back. The rover planners saw this was trending toward a long, hard slog, so we got together to think up some options.” On Oct. 3, they sent commands for Perseverance to test strategies to reduce slippage. First, they had it drive backward up the slope (testing on Earth has shown that under certain conditions the rover’s “rocker-bogie” suspension system maintains better traction during backward driving). Then they tried cross-slope driving (switchbacking) and driving closer to the northern edge of “Summerland Trail,” the name the mission has given to the rover’s route up the crater rim. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video NASA’s Perseverance drives first backward then forward as it negotiates some slippery terrain found along a route up to the rim of Jezero Crater on Oct. 15. The Mars rover used one of its navigation cameras to capture the 31 images that make up this short video.NASA/JPL-Caltech Data from those efforts showed that while all three approaches enhanced traction, sticking close to the slope’s northern edge proved the most beneficial. The rover planners believe the presence of larger rocks closer to the surface made the difference. “That’s the plan right now, but we may have to change things up the road,” said Miller. “No Mars rover mission has tried to climb up a mountain this big this fast. The science team wants to get to the top of the crater rim as soon as possible because of the scientific opportunities up there. It’s up to us rover planners to figure out a way to get them there.” Tube Status In a few weeks, Perseverance is expected to crest the crater rim at a location the science team calls “Lookout Hill.” From there, it will drive about another quarter-mile (450 meters) to “Witch Hazel Hill.” Orbital data shows that Witch Hazel Hill contains light-toned, layered bedrock. The team is looking forward to comparing this new site to “Bright Angel,” the area where Perseverance recently discovered and sampled the “Cheyava Falls” rock. Tracks shown in this image indicate the slipperiness of the terrain Perseverance has encountered during its climb up the rim of Jezero Crater. The image was taken by one of rover’s navigation cameras on Oct. 11. NASA/JPL-Caltech The rover landed on Mars carrying 43 tubes for collecting samples from the Martian surface. So far, Perseverance has sealed and cached 24 samples of rock and regolith (broken rock and dust), plus one atmospheric sample and three witness tubes. Early in the mission’s development, NASA set the requirement for the rover to be capable of caching at least 31 samples of rock, regolith, and witness tubes over the course of Perseverance’s mission at Jezero. The project added 12 tubes, bringing the total to 43. The extras were included in anticipation of the challenging conditions found at Mars that could result in some tubes not functioning as designed. NASA decidedto retire two of the spare empty tubes because accessing them would pose a risk to the rover’s small internal robotic sample-handling arm needed for the task: A wire harness connected to the arm could catch on a fastener on the rover’s frame when reaching for the two empty sample tubes. With those spares now retired, Perseverance currently has 11 empty tubes for sampling rock and two empty witness tubes. More About Perseverance A key objective of Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, to help pave the way for human exploration of the Red Planet and as the first mission to collect and cache Martian rock and regolith. NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Roman Coronagraph is integrated with the Instrument Carrier for NASA’s Nancy Grace Roman Space Telescope in a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Md., in October 2024.NASA/Sydney Rohde NASA’s Nancy Grace Roman Space Telescope team has successfully completed integration of the Roman Coronagraph Instrument onto Roman’s Instrument Carrier, a piece of infrastructure that will hold the mission’s instruments, which will be integrated onto the larger spacecraft at a later date. The Roman Coronagraph is a technology demonstration that scientists will use to take an important step in the search for habitable worlds, and eventually life beyond Earth. This integration took place at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where the space telescope is located and in development. This milestone follows the coronagraph’s arrival at the center earlier this year from NASA’s Jet Propulsion Laboratory (JPL) in Southern California where the instrument was developed, built, and tested. In a clean room at NASA’s Jet Propulsion Laboratory in Southern California in October 2023, scientist Vanessa Bailey stands behind the Roman Coronagraph, which has been undergoing testing at the lab. Designed to block starlight and allow scientists to see the faint light from planets outside our solar system, the Coronagraph is a technology demonstration that will be part of the Roman telescope.NASA/JPL-Caltech The Roman Coronagraph Instrument is a technology demonstration that will launch aboard the Nancy Grace Roman Space Telescope, NASA’s next flagship astrophysics mission. Roman will have a field of view at least 100 times larger than the agency’s Hubble Space Telescope and explore scientific mysteries surrounding dark energy, exoplanets, and infrared astrophysics. Roman is expected to launch no later than May 2027. The mission’s coronagraph is designed to make direct observations of exoplanets, or planets outside of our solar system, by using a complex suite of masks and active mirrors to obscure the glare of the planets’ host stars, making the planets visible. Being a technology demonstration means that the coronagraph’s goal is to test this technology in space and showcase its capabilities. The Roman Coronagraph is poised to act as a technological stepping stone, enabling future technologies on missions like NASA’s proposed Habitable Worlds Observatory, which would be the first telescope designed specifically to search for signs of life on exoplanets. “In order to get from where we are to where we want to be, we need the Roman Coronagraph to demonstrate this technology,” said Rob Zellem, Roman Space Telescope deputy project scientist for communications at NASA Goddard. “We’ll be applying those lessons learned to the next generation of NASA flagship missions that will be explicitly designed to look for Earth-like planets.” A team member works underneath the Instrument Carrier for Roman during the integration of the Coronagraph in a clean room at NASA Goddard in October 2024.NASA/Sydney Rohde A Major Mission Milestone The coronagraph was successfully integrated into Roman’s Instrument Carrier, a large grid-like structure that sits between the space telescope’s primary mirror and spacecraft bus, which will deliver the telescope to orbit and enable the telescope’s functionality upon arrival in space. Assembly of the mission’s spacecraft bus was completed in September 2024. The Instrument Carrier will hold both the coronagraph and Roman’s Wide Field Instrument, the mission’s primary science instrument, which is set to be integrated later this year along with the Roman telescope itself. “You can think of [the Instrument Carrier] as the skeleton of the observatory, what everything interfaces to,” said Brandon Creager, lead mechanical engineer for the Roman Coronagraph at JPL. The integration process began months ago with mission teams from across NASA coming together to plan the maneuver. Additionally, after its arrival at NASA Goddard, mission teams ran tests to prepare the coronagraph to be joined to the spacecraft bus. The Instrument Carrier for Roman is lifted during the integration of the Coronagraph in October 2024 at NASA Goddard.NASA/Sydney Rohde During the integration itself, the coronagraph, which is roughly the size and shape of a baby grand piano (measuring about 5.5 feet or 1.7 meters across), was mounted onto the Instrument Carrier using what’s called the Horizontal Integration Tool. First, a specialized adapter developed at JPL was attached to the instrument, and then the Horizontal Integration Tool was attached to the adapter. The tool acts as a moveable counterweight, so the instrument was suspended from the tool as it was carefully moved into its final position in the Instrument Carrier. Then, the attached Horizontal Integration Tool and adapter were removed from the coronagraph. The Horizontal Integration Tool previously has been used for integrations on NASA’s Hubble and James Webb Space Telescope. As part of the integration process, engineers also ensured blanketing layers were in place to insulate the coronagraph within its place in the Instrument Carrier. The coronagraph is designed to operate at room temperature, so insulation is critical to keep the instrument at the right temperature in the cold vacuum of space. This insulation also will provide an additional boundary to block stray light that could otherwise obscure observations. Following this successful integration, engineers will perform different checks and tests to ensure that everything is connected properly and is correctly aligned before moving forward to integrate the Wide Field Instrument and the telescope itself. Successful alignment of the Roman Coronagraph’s optics is critical to the instrument’s success in orbit. Team members stand together during the integration of the Roman Coronagraph in a clean room at NASA Goddard in October 2024. NASA/Sydney Rohde This latest mission milestone is the culmination of an enduring collaboration between a number of Roman partners, but especially between NASA Goddard and NASA JPL. “It’s really rewarding to watch these teams come together and build up the Roman observatory. That’s the result of a lot of teams, long hours, hard work, sweat, and tears,” said Liz Daly, the integrated payload assembly integration and test lead for Roman at Goddard. “Support and trust were shared across both teams … we were all just one team,” said Gasia Bedrosian, the integration and test lead for the Roman Coronagraph at JPL. Following the integration, “we celebrated our success together,” she added. The Roman Coronagraph Instrument was designed and built at NASA JPL, which manages the instrument for NASA. Contributions were made by ESA (European Space Agency), JAXA (Japan Aerospace Exploration Agency), the French space agency CNES (Centre National d’Études Spatiales), and the Max Planck Institute for Astronomy in Germany. Caltech, in Pasadena, California, manages NASA JPL for the agency. The Roman Science Support Center at Caltech/IPAC partners with NASA JPL on data management for the Coronagraph and generating the instrument’s commands. Virtually tour an interactive version of the telescope The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions.

This image shows nine candidate landing regions for NASA’s Artemis III mission, with each region containing multiple potential sites for the first crewed landing on the Moon in more than 50 years. The background image of the lunar South Pole terrain within the nine regions is a mosaic of LRO (Lunar Reconnaissance Orbiter) WAC (Wide Angle Camera) images.Credit: NASA As NASA prepares for the first crewed Moon landing in more than five decades, the agency has identified an updated set of nine potential landing regions near the lunar South Pole for its Artemis III mission. These areas will be further investigated through scientific and engineering study. NASA will continue to survey potential areas for missions following Artemis III, including areas beyond these nine regions. “Artemis will return humanity to the Moon and visit unexplored areas. NASA’s selection of these regions shows our commitment to landing crew safely near the lunar South Pole, where they will help uncover new scientific discoveries and learn to live on the lunar surface,” said Lakiesha Hawkins, assistant deputy associate administrator, Moon to Mars Program Office. NASA’s Cross Agency Site Selection Analysis team, working closely with science and industry partners, added, and excluded potential landing regions, which were assessed for their science value and mission availability. The refined candidate Artemis III lunar landing regions are, in no priority order: Peak near Cabeus B Haworth Malapert Massif Mons Mouton Plateau Mons Mouton Nobile Rim 1 Nobile Rim 2 de Gerlache Rim 2 Slater Plain These regions contain diverse geological characteristics and offer flexibility for mission availability. The lunar South Pole has never been explored by a crewed mission and contains permanently shadowed areas that can preserve resources, including water. “The Moon’s South Pole is a completely different environment than where we landed during the Apollo missions,” said Sarah Noble, Artemis lunar science lead at NASA Headquarters in Washington. “It offers access to some of the Moon’s oldest terrain, as well as cold, shadowed regions that may contain water and other compounds. Any of these landing regions will enable us to do amazing science and make new discoveries.” To select these landing regions, a multidisciplinary team of scientists and engineers analyzed the lunar South Pole region using data from NASA’s Lunar Reconnaissance Orbiter and a vast body of lunar science research. Factors in the selection process included science potential, launch window availability, terrain suitability, communication capabilities with Earth, and lighting conditions. Additionally, the team assessed the combined trajectory capabilities of NASA’s SLS (Space Launch System) rocket, the Orion spacecraft, and Starship HLS (Human Landing System) to ensure safe and accessible landing sites. The Artemis III geology team evaluated the landing regions for their scientific promise. Sites within each of the nine identified regions have the potential to provide key new insights into our understanding of rocky planets, lunar resources, and the history of our solar system. “Artemis III will be the first time that astronauts will land in the south polar region of the Moon. They will be flying on a new lander into a terrain that is unique from our past Apollo experience,” said Jacob Bleacher, NASA’s chief exploration scientist. “Finding the right locations for this historic moment begins with identifying safe places for this first landing, and then trying to match that with opportunities for science from this new place on the Moon.” NASA’s site assessment team will engage the lunar science community through conferences and workshops to gather data, build geologic maps, and assess the regional geology of eventual landing sites. The team also will continue surveying the entire lunar South Pole region for science value and mission availability for future Artemis missions. This will include planning for expanded science opportunities during Artemis IV, and suitability for the LTV (Lunar Terrain Vehicle) as part of Artemis V. The agency will select sites within regions for Artemis III after it identifies the mission’s target launch dates, which dictate transfer trajectories, or orbital paths, and surface environment conditions. Under NASA’s Artemis campaign, the agency will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

The eastern wall of the Gediz Vallis channel can be seen in the distance. This image was taken on sol 4342 — Martian day 4,342 of the Mars Science Laboratory mission — on Oct. 23, 2024, at 12:29:34 UTC. NASA/JPL-Caltech Earth planning date: Wednesday, Oct. 23, 2024 Curiosity is driving along the western edge of the Gediz Vallis channel, heading for a good vantage point before turning westward and leaving the channel behind to explore the canyons beyond. The contact science for “Chuck Pass” on sol 4341 and backwards 30-meter drive (about 98 feet) on sol 4342 completed successfully. This morning, planning started two hours later than usual. At the end of each rover plan is a baton pass involving Curiosity finishing its activities from the previous plan, transmitting its acquired data to a Mars-orbiting relay satellite passing over Gale Crater, and having that satellite send this data to the Deep Space Network on Earth. This dataset is crucial to our team’s decisions on Curiosity’s next activities. It is not always feasible for us to get our critical data transmitted before the preferred planning shift start time of 8 a.m. This leads to what we call a “late slide,” when our planning days start and end later than usual. Today’s shift began as the “decisional downlink” arrived just before 10 a.m. PDT. The science planning team jumped into action as the data rolled in, completed plans for two sols of science activities, then had to quickly change those plans completely as the Rover Planners perusing new images from the decisional downlink determined that the position of Curiosity’s wheels after the drive would not support deployment of its arm, eliminating the planned use of APXS, MAHLI, and the DRT on interesting rocks in the workspace. However, the science team was able to pivot quickly and create an ambitious two-sol science plan for Curiosity with the other science instruments. On sols 4343-4344, Curiosity will focus on examining blocks of finely layered or “laminated” bedrocks in its workspace. The “Backbone Creek” target, which has an erosion resistant vertical fin of dark material, will be zapped by the ChemCam laser to determine composition, and photographed by Mastcam. “Backbone Creek” is named for a stream in the western foothills of the Sierra Nevada of California flowing through a Natural Research Area established to protect the endangered Carpenteria californica woodland shrub. Curiosity is currently in the “Bishop” quadrangle on our map, so all targets in this area of Mount Sharp are named after places in the Sierra Nevada and Owens Valley of California. A neighboring target rock, “Fantail Lake,” which has horizontal fins among its layers, will also be imaged at high resolution by Mastcam. This target name honors a large alpine lake at nearly 10,000 feet just beyond the eastern boundary of Yosemite National Park. A fractured rock dubbed “Quarter Dome,” after a pair of Yosemite National Park’s spectacular granitic domes along the incomparable wall of Tenaya Canyon between Half Dome and Cloud’s Rest, will be the subject of mosaic images for both Mastcam and ChemCam RMI to obtain exquisite detail on delicate layers across its broken surface (see image). The ChemCam RMI telescopic camera will look at light toned rocks on the upper Gediz Vallis ridge. Curiosity will also do a Navcam dust devil movie and mosaic of dust on the rover deck, then determine dust opacity in the atmosphere using Mastcam. Following this science block, Curiosity will drive about 18 meters (about 59 feet) and perform post-drive imaging, including a MARDI image of the ground under the rover. On sol 4344, the rover will do Navcam large dust devil and deck surveys. It will then use both Navcam and ChemCam for an AEGIS observation of the new location. Presuming that Curiosity ends the drive on more solid footing than today’s location, it will do contact science during the weekend plan, then drive on towards the next fascinating waypoint on our journey towards the western canyons of Mount Sharp.

From left to right, Chilean Ambassador to the United States Juan Gabriel Valdés, Chilean Minister of Science, Technology, Knowledge, and Innovation Aisén Etcheverry Escudero, NASA Administrator Bill Nelson, and United States Department of State Acting Assistant Secretary in the Bureau of Oceans and International Environmental and Scientific Affairs Jennifer R. Littlejohn pose for a photo after the signing of the Artemis Accords, Friday, Oct. 25, 2024, at the Mary W. Jackson NASA Headquarters building in Washington. The Republic of Chile is the 47th country to sign the Artemis Accords, which establish a practical set of principles to guide space exploration cooperation among nations participating in NASA’s Artemis program. NASA/Keegan Barber Chile signed the Artemis Accords Friday during a ceremony hosted by NASA Administrator Bill Nelson at the agency’s headquarters in Washington, becoming the 47th nation and the seventh South American country to commit to the responsible exploration of space for all humanity. “Today we welcome Chile’s signing of the Artemis Accords and its commitment to the shared values of all the signatories for the exploration of space,” said Nelson. “The United States has long studied the stars from Chile’s great Atacama Desert. Now we will go to the stars together, safely, and responsibly, and create new opportunities for international cooperation and the Artemis Generation.” Aisén Etcheverry, minister of science, technology, knowledge and innovation, signed the Artemis Accords on behalf of Chile. Jennifer Littlejohn, acting assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, U.S. Department of State, and Juan Gabriel Valdés, ambassador of Chile to the United States, also participated in the event. “The signing marks a significant milestone for Chile, particularly as our government is committed to advancing technological development as a key pillar of our national strategy,” said Etcheverry. “Chile has the opportunity to engage in the design and development of world-leading scientific and technological projects. Moreover, this collaboration allows us to contribute to areas of scientific excellence where Chile has distinguished expertise, such as astrobiology, geology, and mineralogy, all of which are critical for the exploration and colonization of space.” Earlier in the day, Nelson also hosted the Dominican Republic at NASA Headquarters to recognize the country’s signing of the Artemis Accords Oct. 4. Sonia Guzmán, ambassador of the Dominican Republic to the United States, delivered the signed Artemis Accords to the NASA administrator. Mike Overby, acting deputy assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, U.S. Department of State, and other NASA officials attended the event. In 2020, the United States, led by NASA and the U.S. Department of State, and seven other initial signatory nations established the Artemis Accords, identifying an early set of principles promoting the beneficial use of space for humanity. The Artemis 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.

The diameter of the abrasion patch is 5 centimeters (about 2 inches) and the large green spot in the upper center left of the image is approximately 2 millimeters (about 0.08 inch) in diameter. Mosaic source images have been debayered, flat-fielded, and linearly color stretched. This image was acquired on Aug. 19, 2024 (sol 1243, or Martian day 1,243 of the Mars 2020 mission) at the local mean solar time of 19:45:30. NASA/JPL-Caltech After discovering and sampling the “leopard spots” of “Bright Angel,” it became apparent that Perseverance’s journey of discovery in this region was not yet finished. Approximately 20 sols (Martian days) after driving south across Neretva Vallis from Bright Angel, the rover discovered the enigmatic and unique red rocks of “Serpentine Rapids.” At Serpentine Rapids, Perseverance used its abrading bit to create an abrasion patch in a red rock outcrop named “Wallace Butte.” The 5-cm diameter abrasion patch revealed a striking array of white, black, and green colors within the rock. One of the biggest surprises for the rover team was the presence of the drab-green-colored spots within the abrasion patch, which are composed of dark-toned cores with fuzzy, light green rims. On Earth, red rocks — sometimes called “red beds” — generally get their color from oxidized iron (Fe3+), which is the same form of iron that makes our blood red, or the rusty red color of metal left outside. Green spots like those observed in the Wallace Butte abrasion are common in ancient “red beds” on Earth and form when liquid water percolates through the sediment before it hardens to rock, kicking off a chemical reaction that transforms oxidized iron to its reduced (Fe2+) form, resulting in a greenish hue. On Earth, microbes are sometimes involved in this iron reduction reaction. However, green spots can also result from decaying organic matter that creates localized reducing conditions. Interactions between sulfur and iron can also create iron-reducing conditions without the involvement of microbial life. Unfortunately, there was not enough room to safely place the rover arm containing the SHERLOC and PIXL instruments directly atop one of the green spots within the abrasion patch, so their composition remains a mystery. However, the team is always on the lookout for similar interesting and unexpected features in the rocks. The science and engineering teams are now dealing with incredibly steep terrain as Perseverance ascends the Jezero Crater rim. In the meantime, the Science Team is hanging on to the edge of their seats with excitement and wonder as Perseverance makes the steep climb out of the crater it has called home for the past two years. There is no shortage of wonder and excitement across the team as we contemplate what secrets the ancient rocks of the Jezero Crater rim may hold.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Felipe Valdez, ingeniero de la NASA en el Laboratorio de Investigación de Vuelo a Subescala Dale Reed del Centro de Investigación de Vuelo Armstrong, junto a un modelo a subescala de la aeronave Hybrid Quadrotor (HQ-90).NASA / Charles Genaro Vavuris Read this story in English here. Felipe Valdez es una persona que aprovechó todas las oportunidades posibles en la NASA, trabajando desde que inicio como pasante universitario hasta su trabajo actual como ingeniero de controles de vuelo. Nacido en los Estados Unidos pero criado en México, Valdez enfrentó grandes desafíos mientras crecía. “Mi madre trabajaba por largas horas, mi padre batallaba contra la adicción, y eventualmente la escuela se volvió inaccesible,” dijo Valdez. Determinado a continuar su educación, Valdez tomó la difícil decisión de dejar a su familia y regresar a EE. UU. Pero en su adolescencia, aprender inglés y adaptarse a un nuevo ambiente fue un choque cultural para él. A pesar de estos cambios, su curiosidad por materias como las matemáticas y la ciencia nunca decayó. “De niño, siempre se me ha facilitado trabajar con los números y me fascinaba cómo funcionaban las cosas. La ingeniería combinó ambas cosas,” dijo Valdez. “Eso despertó mi interés.” Mientras estudiaba ingeniería mecánica en la Universidad Estatal de California en Sacramento, la orientación de su profesor, José Granda, resultó fundamental. “Él me animó a solicitar una pasantía en la NASA,” dijo Valdez. “Él había sido portavoz en español para una misión de transbordador [espacial], así que al escuchar que alguien con mis antecedentes tuvo éxito me dio la confianza que yo necesitaba para dar ese paso”. El esfuerzo de Valdez valió la pena – él fue seleccionado como pasante en la Oficina de STEM de la NASA en el Centro Espacial Johnson en Houston. Allí, él trabajó en el desarrollo de software para la dinámica de vehículos, actuadores y modelos de controladores para una cápsula espacial en simulaciones por computadora. “No podía creerlo,” dijo Valdez. “Conseguir esa oportunidad cambió todo.” Esta pasantía abrió la puerta a una segunda oportunidad con la NASA, esta vez en el Centro de Investigación de Vuelo Armstrong de la agencia en California. Tuvo la oportunidad de trabajar en el desarrollo de computadoras de vuelo para el Diseño Aerodinámico de Investigación Preliminar para Disminuir la Resistencia, un diseño experimental de ala volante. Después de estas experiencias, fue aceptado como un pasante en el Programa Pathways de la NASA, un programa de trabajo y estudio que ofrece la posibilidad de trabajar a tiempo completo en la NASA después de graduarse. “Eso fue el comienzo de mi carrera en la NASA, donde realmente despego mi pasión por la aeronáutica,” dijo Valdez. Valdez fue el primero en su familia en seguir una educación superior, obteniendo su licenciatura en la Universidad Estatal de Sacramento y su maestría en ingeniería mecánica y aeroespacial en la Universidad de California, Davis. Hoy en día, trabaja como ingeniero de controles de vuelo de la NASA en la rama de Dinámica y Controles del centro Armstrong. La mayor parte de su experiencia se ha centrado en el desarrollo de simulaciones de vuelo y diseño de sistemas de control, particularmente para aviones de propulsión eléctrica distribuida. “Es gratificante formar parte de un grupo que se centra en hacer que la aviación sea más rápida, más silenciosa, y más sostenible,” dijo Valdez. “Como ingeniero de controles, trabajar en conceptos avanzados de aeronaves como la propulsión eléctrica distribuida me permite diseñar algoritmos para controlar directamente múltiples motores, mejorando la seguridad, la controlabilidad y la estabilidad, al tiempo que permite operaciones más limpias y silenciosas que amplían los límites de la aviación sostenible.” A lo largo de su carrera, Valdez se ha sentido orgulloso de su herencia. “Siento un fuerte orgullo de saber que la inclusión es uno de nuestros valores fundamentales aquí en la NASA y que las oportunidades están abiertas para todos.” Crédito: NASA / Charles Genaro Vavuris Entrevistadora: NASA/ Lupita L Alcala Facebook logo @NASA@NASAaero@NASA_es @NASA@NASAaero@NASA_es Instagram logo @NASA@NASAaero@NASA_es Linkedin logo @NASA Explore More 3 min read Sacrifice and Success: NASA Engineer Honors Family Roots Article 1 week ago 4 min read Sacrificio y Éxito: Ingeniero de la NASA honra sus orígenes familiares Article 1 week ago 3 min read NASA Spotlight: Felipe Valdez, an Inspiring Engineer Article 2 weeks ago Keep Exploring Discover More Topics From NASA Missions Artemis Aeronautics STEM Explore NASA’s History Share Details Last Updated Oct 25, 2024 EditorLillian GipsonContactJessica Arreolajessica.arreola@nasa.govLocationArmstrong Flight Research Center Related TermsNASA en españolAeronáuticaHispanic Heritage Month View the full article

ESA/Hubble & NASA, M. Sun The spiral galaxy in this NASA/ESA Hubble Space Telescope image is IC 3225. It looks remarkably as if it was launched from a cannon, speeding through space like a comet with a tail of gas streaming from its disk behind it. The scenes that galaxies appear in from Earth’s point of view are fascinating; many seem to hang calmly in the emptiness of space as if hung from a string, while others star in much more dynamic situations! Appearances can be deceiving with objects so far from Earth — IC 3225 itself is about 100 million light-years away — but the galaxy’s location suggests some causes for this active scene, because IC 3225 is one of over 1,300 members of the Virgo galaxy cluster. The density of galaxies in the Virgo cluster creates a rich field of hot gas between them, called ‘intracluster medium’, while the cluster’s extreme mass has its galaxies careening around its center in some very fast orbits. Ramming through the thick intracluster medium, especially close to the cluster’s center, places enormous ‘ram pressure’ on the moving galaxies that strips gas out of them as they go. As a galaxy moves through space, the gas and dust that make up the intracluster medium create resistance to the galaxy’s movement, exerting pressure on the galaxy. This pressure, called ram pressure, can strip a galaxy of its star-forming gas and dust, reducing or even stopping the creation of new stars. Conversely, ram pressure can also cause other parts of the galaxy to compress, which can boost star formation. IC 3225 is not so close to the cluster core right now, but astronomers have deduced that it has undergone ram pressure stripping in the past. The galaxy looks compressed on one side, with noticeably more star formation on that leading edge (bottom-left), while the opposite end is stretched out of shape (upper-right). Being in such a crowded field, a close call with another galaxy may also have tugged on IC 3225 and created this shape. The sight of this distorted galaxy is a reminder of the incredible forces at work on astronomical scales, which can move and reshape entire galaxies! View the full article

Earth Observer Earth Home Earth Observer Home Editor’s Corner Feature Articles Meeting Summaries News Science in the News Calendars In Memoriam More Archives 3 min read Autumn Leaves – Call for Volunteers The Global Learning and Observations to Benefit the Environment (GLOBE) Program is calling on volunteers of all ages to help students and citizen scientists document seasonal change through leaf color and land cover. The data collection event will support students across North America, Latin America, Central America, and Europe, who are working together to document the seasonal changes taking place from September through December – see Figure. The observations will also provide vital data for GLOBE students creating student research projects for the GLOBE 2025 International Virtual Science Symposium (IVSS). The project is part of GLOBE’s Intensive Observation Period (IOP), which collects data during a focused period to assess how climate change is unfolding in different regions of the world. Figure. Locations Green-Down observations being entered into the GLOBE database. Figure credit: GLOBE Green down is the seasonal change when leaves change from green to brown and then fall to the ground. During green-down data collection, volunteers take regular, daily photos of trees to document the transition in color. Regular observations of land cover and tree height capture the broader changes happening around the tree. By gathering this data, you can provide important information about when a single tree changes ahead of or behind the others in your region. When this data is paired with satellite observations, researchers gain a much stronger picture of how seasonal and climate variations impact the life cycles of plants and animals. The GLOBE European Phenology Campaign has created materials to assist educators in these efforts. This includes a series of YouTube videos that volunteers can use to select a tree for the phenology project, estimate tree height, and assess land cover. In addition, volunteers can refer to the green-down protocol for guidance at the beginning of the survey. Educators can learn more about the importance of the green-down study by registering as a GLOBE Educator at the GLOBE “Create an Account” website. GLOBE students have been collecting seasonal variability in plant and animal data for decades. This work will augment global databases to help students, educators, and scientists around the world study climate change. These observations are taking place around the world. This IOP is being conducted in conjunction with the GLOBE North America Phenology Campaign and the European Phenology Campaign, which focus on monitoring and reporting of cycles in plants and animals to help validate the timing of changes in growing season and habitat. The work is also being conducted in conjunction with the Trees Within LAC Campaign, which is collecting information about tree species and their dynamics over time.
