NASA/JPL-Caltech Earth planning date: Friday, July 26, 2024 Today’s 2-sol weekend plan is our first taste of a new location for a potential sampling campaign. We call today’s plan type: Drill Sol 1 – triage contact science. We arrived this morning to a lovely new workspace. The science team has been eagerly observing these lighter-toned rocks first from orbital data, then from our drive direction imaging as we approached them, and now they are right in front of us! Because the science team had been contemplating the possibility of sampling these rocks, the drive that we planned on Wednesday ended in just the right orientation in case the team does decide to drill here. Variables that matter are the rover roll and pitch – so that we can both drill the rock safely but also then deliver sample to our two internal instruments, CheMin and SAM. Additionally, the rover heading needs to be just right so that we can communicate clearly with Earth – perhaps for several weeks if we remain for a campaign! We have specially certified Rover Planners called Sampling Campaign Rover Planners (SCaRPs) and they go into action on Drill Sol 1 to confirm that all those special considerations for drilling are met including finding the actual target on the ground that we want to assess. This morning, the SCaRPs swiftly found a great target and we named it “Kings Canyon.” Kings Canyon National Park is in the southern Sierra Nevada range in California. Kings Canyon itself is a glacially carved canyon more than a mile deep! The national park also contains some of the world’s largest stands of Giant Sequoia trees. The Drill Sol 1 plan has two purposes – first to determine if our target, Kings Canyon, meets the science teams criteria for sampling – for example, is it compositionally interesting? The second objective is to determine if the rock and specific target, are safe to drill; can it handle the forces from the drill, for example. We call this activity a “drill preload test.” Therefore, the primary activities in today’s plan are the preload test and contact science on Kings Canyon – we will first brush the target to remove surface dust and then take close-up imaging with our MAHLI instrument and compositional data with our APXS instrument. In anticipation of a notional full drill on Monday, today’s team was very conservative with the amount of power we used. This meant limiting our remote sensing observations to only those that the team thought were most important to get down timely to support a drill campaign. We’ll use our ChemCam instrument to also study Kings Canyon, ChemCam provides complementary compositional data to the APXS observations. Together these observations will help inform the science about whether they want to proceed with sampling. Today’s plan also includes our typical environmental monitoring observations that we take at a regular cadence. Hope your weekend is as busy and fun as Curiosity’s!

We wrapped up our Mammoth Lakes drill campaign only three weeks ago and are already looking for our next drill site. This will be the last drill campaign in the Gediz Vallis region, an area on Mars the Curiosity team has had their eyes on since sol 0, just under 12 years ago! This upcoming campaign is even more exciting after the elemental sulfur we found at Mammoth Lakes. And while sulfur on its own doesn’t smell, I’ve always wondered… what does Mars smell like? Finding ourselves less than a meter from our hopeful end-of-drive on Monday, we started on a very familiar plan: Starting with an arm backbone for removing dust and using APXS to investigate a bedrock target named “Russell Pass,” placing the arm out of the way for imaging, spending just over an hour on Mastcam imaging and ChemCam LIBS on Russell Pass, then one more arm backbone for MAHLI images of Russell Pass, and finally a drive in the afternoon. These plans, dubbed “touch-and-go” plans, are usually busy at the start and slow at the end. Our drive this time is planned to go ~10 meters almost perfectly east and leaving our heading almost perfectly west. If on Friday, our wheels are solidly on the Martian ground and there is a flat-enough bedrock surface to place our drill, we might be staying put for another two weeks while we try and collect another Gediz Vallis channel sample. And since we drive backwards with the arm taking up the rear, we might even have a workspace we’ve already driven over – hopefully exposing some internal bedrock even before drilling.

Long before Apollo astronauts set foot upon the Moon, much remained unknown about the lunar surface. While most scientists believed the Moon had a solid surface that would support astronauts and their landing craft, some believed a deep layer of dust covered it that would swallow any visitors. Until 1964, no closeup photographs of the lunar surface existed, only those obtained by Earth-based telescopes and grainy low-resolution images of the Moon’s far side obtained in 1959 by the Soviet Luna 3 robotic spacecraft. On July 28, 1964, Ranger 7 launched toward the Moon, and three days later returned not only the first images of the Moon taken by an American spacecraft but also the first high resolution close-up photographs of the lunar surface. The mission marked a turning point in America’s lunar exploration program, taking the country one step closer to a human Moon landing. Left: Block I Ranger 1 spacecraft under assembly at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. Middle: Block II Ranger spacecraft, showing the black-and-white spherical landing capsule. Right: Block III Ranger 7 spacecraft under assembly at JPL. The Ranger program, initiated in 1960 and managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, sought to acquire the first high resolution close-up images of the lunar surface. The program consisted of three phases of increasing complexity. The first phase of the program, designated “Block I,” intended to test the Atlas-Agena launch vehicle by placing a Ranger spacecraft in a highly elliptical Earth orbit where its equipment could be tested. The second “Block II” phase built on the lessons of Block I to send three spacecraft to the Moon to collect images and data and transmit them back to Earth. Each Block II Ranger carried a television camera for collecting images, a gamma-ray spectrometer for studying the minerals in the lunar rocks and soil, and a radar altimeter for studying lunar topography. These spacecraft carried a capsule, encased in balsa wood to protect it from the impact of landing, containing a seismometer and transmitter that would be able to operate for up to 30 days after being dropped on the lunar surface. The final “Block III” phase consisted of four spacecraft that each carried a high-resolution imaging system consisting of six television cameras with wide- and narrow-angle capabilities. They could take 300 pictures per minute. The Block I and II Rangers met with limited success. Neither Ranger 1 nor 2 left low Earth orbit due to booster problems. Ranger 3, the first Block II spacecraft, missed the Moon by 22,000 miles and sailed on into solar orbit, returning no photographs but taking the first measurements of the interplanetary gamma ray flux. Ranger 4 has the distinction as the first American spacecraft to impact the Moon, and on its far side to boot, but due to a power failure in its central computer could not return any images or data. Ranger 5 missed the Moon by 450 miles but also failed to return images due to a power failure and entered solar orbit. None of the Block II Rangers delivered their seismometer-carrying capsules to the Moon’s surface. Ranger 6, the first Block III spacecraft, successfully impacted on the Moon in January 1964, but its television system failed to return any images due to a short circuit. NASA and JPL delayed the next mission until a thorough investigation identified the source of the problem and engineers completed corrective actions. All hopes rested on Ranger 7 to redeem the program. Left: Schematic diagram of a Block III Ranger, showing its major components. Middle: The television camera system aboard Ranger 7. Right: Launch of Ranger 7. On July 28, 1964, Ranger 7 launched from Cape Canaveral, Florida. The Atlas-Agena rocket first placed the spacecraft into Earth orbit before sending it on a lunar trajectory. The next day, the spacecraft successfully carried out a mid-course correction, and on July 31, Ranger 7 reached the Moon. This time, the spacecraft’s cameras turned on as planned. During its final 17 minutes of flight, the spacecraft sent back 4,308 images of the lunar surface. The last image, taken 2.3 seconds before Ranger 7 impacted at 1.62 miles per second, had a resolution of just 15 inches. Scientists renamed the area where it crashed – between Mare Nubium and Oceanus Procellarum – as Mare Cognitum, Latin for “The Known Sea,” to commemorate the first spot on the Moon seen close-up.

Right: Lunar Reconnaissance Orbiter image of the Ranger 7 impact crater, taken in 2010 at a low sun angle. Two more Ranger missions followed. Ranger 8 returned more than 7,000 images of the Moon. NASA and JPL broadcast Ranger 9’s images of the Alphonsus crater and the surrounding area “live” as the spacecraft approached its crash site in the crater – letting millions of Americans see the Moon up-close as it happened. Based on the photographs returned by the last three Rangers, scientists felt confident to move on to the next phase of robotic lunar exploration, the Surveyor series of soft landers. The Ranger photographs provided confidence that the lunar surface could support a soft-landing. Just under five years after Ranger 7 returned its historic images, Apollo 11 landed the first humans on the Moon. Enjoy a brief video about Ranger 7, or a more detailed video of the entire mission.

Daily global average temperature values from MERRA-2 for the years 1980-2022 are shown in white, values for the year 2023 are shown in pink, and values from 2024 through June are shown in red. Daily global temperature values from July 1-July 23, 2024, from GEOS-FP are shown in purple. NASA/Global Modeling and Assimilation Office/Peter Jacobs July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-term warming trend driven by human activities, primarily the emission of greenhouse gases. As part of its mission to expand our understanding of Earth, NASA collects critical long-term observations of our changing planet. “In a year that has been the hottest on record to date, these past two weeks have been particularly brutal,” said NASA Administrator Bill Nelson. “Through our over two dozen Earth-observing satellites and over 60 years of data, NASA is providing critical analyses of how our planet is changing and how local communities can prepare, adapt, and stay safe. We are proud to be part of the Biden-Harris Administration efforts to protect communities from extreme heat.” This preliminary finding comes from data analyses from Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) and Goddard Earth Observing System Forward Processing (GEOS-FP) systems, which combine millions of global observations from instruments on land, sea, air, and satellites using atmospheric models. GEOS-FP provides rapid, near-real time weather data, while the MERRA-2 climate reanalysis takes longer but ensures the use of best quality observations. These models are run by the Global Modeling and Assimilation Office (GMAO) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Daily global average temperature values from MERRA-2 for the years 1980-2022 are shown in white, values for the year 2023 are shown in pink, and values from 2024 through June are shown in red. Daily global temperature values from July 1 to 23, 2024, from GEOS-FP are shown in purple. The results agree with an independent analysis from the European Union’s Copernicus Earth Observation Programme. While the analyses have small differences, they show broad agreement in the change in temperature over time and hottest days. The latest daily temperature records follow 13 months of consecutive monthly temperature records, according to scientists from NASA’s Goddard Institute for Space Studies in New York. Their analysis was based on the GISTEMP record, which uses surface instrumental data alone and provides a longer-term view of changes in global temperatures at monthly and annual resolutions going back to the late 19th century.

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Science in Space: July 2024 This time of year, managing heat is on everyone’s mind. Especially now, as May 2024 marked a full year of record-high monthly temperatures – an unprecedented streak, according to scientists from NASA’s Goddard Institute for Space Studies in New York. NASA experts analyze data from thousands of land-, sea-, and sky-based instruments to calculate Earth’s global temperature. Knowing how hot it is helps scientists, health care workers, and public officials plan for and respond to the heat’s effects on people and infrastructure. Crew members on the International Space Station deal with a different type of heat – that generated by electronics, life support systems, and other equipment. Managing this heat is essential to the operation of the spacecraft and the health and safety of its occupants. Taking out the heat Hardware for the packed bed water recovery reactor experiment. The packing media is visible in the long clear tube.NASA Packed bed reactors (PBRs) are structures packed with beads of different materials to increase contact between a liquid and a gas flowing through them. They are widely used for many applications, including thermal control or heat management, life support systems, and water filtration and offer low power consumption, compact size, and reliability. Packed Bed Reactor Experiment: Water Recovery Series (PBRE-WRS) continues evaluation of how microgravity affects the performance of different packing media. The material used and the shape and size of the beads all contribute to the effectiveness of heat exchange in a PBR. This investigation could inform the design and operation of these systems in microgravity and on the Moon and Mars and lead to improvements in this technology for applications on Earth such as water purification and cooling systems. Previous investigations, PBRE and PBRE-2, provided fundamental understanding of simultaneous gas and liquid flow through PBRs in microgravity. This improved understanding helps to support development of more efficient and lightweight thermal management and life support systems for future missions. Boiling heat away To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video In this video from the FBCE, as liquid begins to boil, small bubbles form at the heated surface (top of the image) and grow larger over time.NASA As electronic devices add more features, they generate more heat, which becomes increasingly challenging to remove. Flow boiling is a method of thermal management that uses this heat to boil a moving liquid and generate vapor bubbles that lift the heat from the surface, then change back to a liquid via condensation. But using boiling for heat management is less efficient in microgravity because, in the absence of buoyancy, bubbles grow larger and remain near the surface. The Flow Boiling and Condensation Experiment (FBCE) tested a model for a flow boiling and condensation facility for the space station. Researchers identified important factors affecting this process in microgravity and how they differ from those on Earth. The findings could help researchers identify ways to improve the operation of these systems in microgravity. This research also led to development of an artificial neural network (ANN) trained on data from the FBCE experiment to predict heat flow and transfer for use in the design and analysis of thermal systems. ANNs are a type of artificial intelligence made of computational units similar to neurons in the nervous systems of living things. NASA astronaut Josh Cassada works on the PFMI-ASCENT investigation.NASA The PFMI-ASCENT investigation found that adding microscopic teeth or rachets to a surface caused more bubbles to form and increased the transfer of heat. This finding helps further improve flow boiling systems used to remove heat from electronics in space. Going with the flow Close-up view of the Capillary Flow Experiment-2 test chamber.NASA Liquids behave differently in space than they do on Earth. Capillary Flow Experiment-2 studied wetting, or a liquid’s ability to spread across a surface, in different container shapes in microgravity. Results showed that models adequately predict liquid flow for various container shapes. These predictions support improved design of systems that process liquids aboard spacecraft, including systems for thermal control.

NASA’s LRO (Lunar Reconnaissance Orbiter) has twice transmitted a laser pulse to a cookie-sized retroreflector aboard JAXA’s (Japan Aerospace Exploration Agency) SLIM lander on the Moon and received a return signal. As LRO passed 44 miles above SLIM (Smart Lander for Investigating Moon) during two successive orbits on May 24, 2024, it pinged the lander with its laser altimeter instrument as it had done eight times before. But, on these two attempts, the signal bounced back to LRO’s detector. This was an important accomplishment for NASA because the device is not in an optimal position. Retroreflectors are typically secured to the top of landers, giving LRO a 120-degree range of angles to aim toward when sending laser pulses to the approximate location of a retroreflector. However, the SLIM lander had settled on the surface with its top facing sideways, limiting LRO’s range. To boost the chances of reaching their target, the LRO team worked with JAXA to determine the exact location and orientation of SLIM. Then, NASA engineers predicted when LRO’s orbit trajectory would bring it to coordinates that would give it the best chance of reaching SLIM’s retroreflector with the laser beams. SLIM on the lunar surface captured by the LEV-2 (SORA-Q) rover. “LRO’s altimeter wasn’t built for this type of application, so the chances of pinpointing a tiny retroreflector on the Moon’s surface are already low,” said Xiaoli Sun, who led the team that built SLIM’s retroreflector at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as part of a partnership between NASA and JAXA. “For the LRO team to have reached a retroreflector that faces sideways, instead of the sky, shows that these little devices are incredibly resilient,” Sun said. SLIM touched down on the Moon’s surface on Jan. 20. The retroreflector that hitched a ride with the lander, called a Laser Retroreflector Array, is one of the six NASA has sent to the Moon aboard private and public landers, and the second to bounce signal back to LRO’s altimeter. The first time a laser beam was transmitted from LRO to a NASA retroreflector and back was on Dec. 12, 2023, when LRO pinged ISRO’s (Indian Space Research Organisation) Vikram lander. LRO has since exchanged laser pings with Vikram three more times. NASA’s retroreflector has eight quartz corner-cube prisms set into a dome-shaped aluminum frame that is 2 inches wide. With no power or maintenance required, retroreflectors can last on the Moon’s surface for decades and thus provide reliable beacons for future missions. NASA’s Laser Retroreflector Array installed on JAXA’s SLIM lander before launch. The retroreflectors could guide Artemis astronauts to the surface in the dark, for example, or mark the locations of spacecraft already on the surface to help astronauts and uncrewed spacecraft land near them. LRO’s laser altimeter, the only laser instrument orbiting the Moon for now, was designed to map the Moon’s topography to prepare for missions to the surface — not to point to within 1/100th of a degree of a retroreflector, which is what LRO engineers are trying to do with every ping. LRO is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington. Launched on June 18, 2009, LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon. NASA is returning to the Moon with commercial and international partners to expand human presence in space and bring back new knowledge and opportunities.

High-gain antennas are an important component of Gateway’s communication and tracking system that connects operations across the vast distances of the lunar South Pole region, to Gateway in orbit around the Moon, to Earth, and back again. NASA is conducting rigorous testing on the electric field levels radiated by the antennas to ensure safe and efficient communication and to avoid any interference with Gateway’s crew and equipment. By validating simulation models to accurately predict electric field levels, NASA can establish precise safety zones around the K/Ka-band parabolic reflector antennas to protect astronauts and hardware without sacrificing high-rate communications. During the meticulous testing process, engineers use electric field and waveguide probes, which measure the strength and quality of electromagnetic signals, to scan the near fields of a representative high-gain antenna. Robotic arms and optical tracking systems provide the precise measurements needed for model validation. The testing is being conducted in an anechoic chamber, a specialized room that provides a controlled environment for measurements of electromagnetic waves. “We are sharpening our pencil in conducting model validation measurements – ensuring high accuracy in the analysis of electric fields radiated by the high-gain antennas on Gateway,” said Timothy Kennedy, one of the NASA engineers overseeing the tests. “This enables reduced margins on antenna masking needed to protect equipment and crew, while maximizing communication coverage.” Findings are expected to enhance NASA’s understanding of the electric field levels emitted by Gateway’s antennas and inform critical decisions for operating them safely during Artemis missions, ensuring that Gateway is a safe home for astronauts around the Moon.

Behind Diane is the SOFIA aircraft and her arm rests on a railing beside her. Credit: Diane Ripollone A 35-year-veteran educator, Diane Ripollone teaches Earth science, astronomy, and physics to high school students in North Carolina. In her decades of experience, she’s seen firsthand how students with physical challenges can face difficulties in connecting with lessons. She decided to tackle the issue head-on with her internship. Ripollone supports the My NASA Data Program, which provides educational materials to interact with live data collected by NASA satellites, observatories, and sensors worldwide. As a NASA intern, she has worked to create physical materials with braille for students with- vision limitations. “It’s a start for teachers,” Ripollone said. “Although every classroom is different, this helps to provide teachers a jumpstart to make engaging lesson plans centered around real NASA data.” Her NASA internship has excited and inspired her students, according to Ripollone. “My students have been amazed! I see their eyes open wide,” she said. “They say, ‘My teacher is working for NASA!'” Felicia Haseleu: Improving Reading and Writing Skills North Dakota teacher Felicia Haseleu never imagined she’d be a NASA intern until a colleague forwarded the opportunity to her inbox. A teacher on her 11th year, she has seen how COVID-19 has affected students: “It’s caused a regression in reading and writing ability,” a shared impact that was seen in students nationwide. A science teacher passionate about reading and writing, Felicia set out to utilize these in the science curriculum. As an intern with My NASA Data, she’s prepared lesson plans that combine using the scientific method with creative writing, allowing students to strengthen their reading and writing skills while immersing themselves in science. Haseleu anticipates her NASA internship will provide benefits inside and outside the classroom. “It’s going to be awesome to return to the classroom with all of these materials,” she said. “Being a NASA intern has been a great experience! I’ve felt really supported and you can tell that NASA is all encompassing and supports one another. From the camaraderie to NASA investing in interns, it’s nice to feel valued by NASA.” Teri Minami: Hands-on Lesson for Neurodivergent and Artistic Students Teri Minami poses in a white lab coat, lilac gloves, glasses, and “Dexter” name tag.

ESA/Hubble & NASA, C. Kilpatrick This NASA/ESA Hubble Space Telescope image treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor. Several other galaxies, located relatively nearby to this one, are just beyond the frame of this image; one is close enough that gravitational interaction is driving some star formation in NGC 3430 — visible as bright-blue patches near to but outside of the galaxy’s main spiral structure. This fine example of a galactic spiral holds a bright core from which a pinwheel array of arms appears to radiate outward. Dark dust lanes and bright star-forming regions help define these spiral arms. NGC 3430’s distinct shape may be one reason why astronomer Edwin Hubble used to it to help define his classification of galaxies. Namesake of the Hubble Space Telescope, Edwin Hubble authored a paper in 1926 that outlined the classification of some four hundred galaxies by their appearance — as either spiral, barred spiral, lenticular, elliptical, or irregular. This straightforward typology proved extremely influential, and the detailed schemes astronomers use today are still based on Edwin Hubble’s work. NGC 3430 itself is a spiral lacking a central bar with open, clearly defined arms — classified today as an SAc galaxy. Image credit: ESA/Hubble & NASA, C. Kilpatrick View the full article

5 Min Read NASA Returns to Arctic Studying Summer Sea Ice Melt NASA's Gulfstream III aircraft taxis on the runway at Pituffik Space Base as it begins one of its daily science flights for the ARCSIX mission. Credits: NASA/Gary Banziger What happens in the Arctic doesn’t stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth’s rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost part of Earth have a large impact on the entire planet. That’s because the Arctic region acts like Earth’s air conditioner. Much of the Sun’s energy is transported from tropical regions of our planet by winds and weather systems into the Arctic where it is then lost to space. This process helps cool the planet. The NASA-sponsored Arctic Radiation Cloud Aerosol Surface Interaction Experiment (ARCSIX) mission is flying three aircraft over the Arctic Ocean north of Greenland to study these processes. The aircraft are equipped with instruments to gather observations of surface sea ice, clouds, and aerosol particles, which affect the Arctic energy budget and cloud properties. The energy budget is the balance between the energy that Earth receives from the Sun and the energy the Earth loses to outer space.

Less sea ice lessens the Arctic’s cooling effect,” says Patrick Taylor, a climate scientist at NASA’s Langley Research Center in Hampton, Virginia. “Over the last 40 years, The Arctic has lost a significant amount of sea ice making the Arctic warm faster. As the Arctic warms and sea ice melts, it can cause ripple effects that impact weather conditions thousands of miles away, how fast our seas are rising, and how much flooding we get in our neighborhoods.” As the Arctic warms and sea ice melts, it can cause ripple effects…thousands of miles away. Patrick Taylor NASA Climate Research Scientist The first series of flights took place in May and June as the seasonal melting of ice started. Flights began again on July 24 during the summer season, when sea ice melting is at its most intense. “We can’t do this kind of Arctic science without having two campaigns,” said Taylor, the deputy science lead for ARCSIX. “The sea ice surface in the spring was very bright white and snow covered. We saw some breaks in the ice. What we will see in the second campaign is less sea ice and sea ice that is bare, with no snow. It will be covered with all kinds of melt ponds – pooling water on top of the ice – that changes the way the ice interacts with sunlight and potentially changes how the ice interacts with the atmosphere and clouds above.” Sea ice and the snow on top of the ice insulate the ocean from the atmosphere, reflecting the Sun’s radiation back towards space, and helping to cool the planet. Less sea ice and darker surfaces result in more of the Sun’s radiation being absorbed at the surface or trapped between the surface and the clouds.

I can’t wait to see the changes at the height of melt as we measure the same areas covered with melt ponds.” NASA partnered with the University of Colorado Boulder for the ARCSIX mission, and the research team found some surprises in their early data analysis from the spring campaign. One potential discovery is something Taylor is calling a “sea ice sandwich”, when a younger layer of sea ice is caught in between two layers of older sea ice. Scientists also found more drizzle within the clouds than expected. Both observations will need further investigating once the data is fully processed. A research scientist monitors data measurements in-flight during the spring campaign of the ARCSIX mission.NASA/Gary Banziger “A volcano erupted in Iceland, and we believe the volcanic aerosol plume was indicated by our models four days later,” Taylor said. “Common scientific knowledge tells us volcanic particles, like ash and sulfate, would have already been removed from the atmosphere. More work needs to be done, but our initial results suggest these particles might live in the atmosphere much longer than previously thought.” Previous studies suggest that aerosol particles in clouds can influence sea ice melt. Data collected during ARCSIX’s spring flights showed the Arctic atmosphere had several aerosol particle layers, including wildfire smoke, pollution, and dust transported from Asia and North America. “We got everything we hoped for and more in the first campaign,” Taylor added. “The data from this summer will help us better understand how clouds and sea ice behave. We’ll be able to use these results to improve predictive models. In the coming years, scientists will be able to better predict how to mitigate and adapt to the rapid changes in climate we’re seeing in the Arctic.” Read More ESPO.NASA.gov AIR.LARC.NASA.gov NASA.gov/Earth Share Details Last Updated Jul 26, 2024 EditorCharles G.

Crane operator Rebekah Tolatovicz, a shift mechanical technician lead for Artic Slope Regional Corporation at NASA’s Kennedy Space Center in Florida, operates a 30-ton crane to lift the agency’s Artemis II Orion spacecraft out of the recently renovated altitude chamber to the Final Assembly and Systems Testing, or FAST, cell inside NASA Kennedy’s Neil A. Armstrong Operations and Checkout Building on April 27. During her most recent lift July 10, Tolatovicz helped transfer Orion back to the FAST cell following vacuum chamber qualification testing in the altitude chamber earlier this month. This lift is one of around 250 annual lifts performed at NASA Kennedy by seven operator/directors and 14 crane operators on the ASRC Orion team. “At the time of the spacecraft lift, I focus solely on what’s going on in the moment of the operation,” explains Tolatovicz. “Listening for the commands from the lift director, making sure everyone is safe, verifying the vehicle is clear, and ensuring the crane is moving correctly.” All Orion crane operators are certified after classroom and on-the-job training focusing on areas such as rigging, weight and center of gravity, mastering crane controls, crane securing, assessing safety issues, and emergency procedures. Once certified, they progress through a series of the different lifts required for Orion spacecraft operations, from simple moves to the complex full spacecraft lift. “It’s not until after the move is complete and the vehicle is secured that I have a moment to think about how awesome it is to be a part of history on the Orion Program and do what I get to do every day with a team of the most amazing people,” Tolatovicz said.

4 min read NASA’s Fermi Finds New Feature in Brightest Gamma-Ray Burst Yet Seen In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA’s Fermi Gamma-ray Space Telescope reveals a feature never seen before. The brightest gamma-ray burst yet recorded gave scientists a new high-energy feature to study. Learn what NASA’s Fermi mission saw, and what this feature may be telling us about the burst’s light-speed jets. Credit: NASA’s Goddard Space Flight Center Download high-resolution video and images from NASA’s Scientific Visualization Studio “A few minutes after the BOAT erupted, Fermi’s Gamma-ray Burst Monitor recorded an unusual energy peak that caught our attention,” said lead researcher Maria Edvige Ravasio at Radboud University in Nijmegen, Netherlands, and affiliated with Brera Observatory, part of INAF (the Italian National Institute of Astrophysics) in Merate, Italy. “When I first saw that signal, it gave me goosebumps. Our analysis since then shows it to be the first high-confidence emission line ever seen in 50 years of studying GRBs.” A paper about the discovery appears in the July 26 edition of the journal Science. When matter interacts with light, the energy can be absorbed and reemitted in characteristic ways. These interactions can brighten or dim particular colors (or energies), producing key features visible when the light is spread out, rainbow-like, in a spectrum. These features can reveal a wealth of information, such as the chemical elements involved in the interaction. At higher energies, spectral features can uncover specific particle processes, such as matter and antimatter annihilating to produce gamma rays. “While some previous studies have reported possible evidence for absorption and emission features in other GRBs, subsequent scrutiny revealed that all of these could just be statistical fluctuations. What we see in the BOAT is different,” said coauthor Om Sharan Salafia at INAF-Brera Observatory in Milan, Italy. “We’ve determined that the odds this feature is just a noise fluctuation are less than one chance in half a billion.” A jet of particles moving at nearly light speed emerges from a massive star in this artist’s concept. The star’s core ran out of fuel and collapsed into a black hole. Some of the matter swirling toward the black hole was redirected into dual jets firing in opposite directions. We see a gamma-ray burst when one of these jets happens to point directly at Earth. NASA’s Goddard Space Flight Center Conceptual Image Lab GRBs are the most powerful explosions in the cosmos and emit copious amounts of gamma rays, the highest-energy form of light. The most common type occurs when the core of a massive star exhausts its fuel, collapses, and forms a rapidly spinning black hole. Matter falling into the black hole powers oppositely directed particle jets that blast through the star’s outer layers at nearly the speed of light. We detect GRBs when one of these jets points almost directly toward Earth. The BOAT, formally known as GRB 221009A, erupted Oct. 9, 2022, and promptly saturated most of the gamma-ray detectors in orbit, including those on Fermi. This prevented them from measuring the most intense part of the blast. Reconstructed observations, coupled with statistical arguments, suggest the BOAT, if part of the same population as previously detected GRBs, was likely the brightest burst to appear in Earth’s skies in 10,000 years. The putative emission line appears almost 5 minutes after the burst was detected and well after it had dimmed enough to end saturation effects for Fermi. The line persisted for at least 40 seconds, and the emission reached a peak energy of about 12 MeV (million electron volts). For comparison, the energy of visible light ranges from 2 to 3 electron volts. So what produced this spectral feature? The team thinks the most likely source is the annihilation of electrons and their antimatter counterparts, positrons. “When an electron and a positron collide, they annihilate, producing a pair of gamma rays with an energy of 0.511 MeV,” said coauthor Gor Oganesyan at Gran Sasso Science Institute and Gran Sasso National Laboratory in L’Aquila, Italy. “Because we’re looking into the jet, where matter is moving at near light speed, this emission becomes greatly blueshifted and pushed toward much higher energies.” If this interpretation is correct, to produce an emission line peaking at 12 MeV, the annihilating particles had to have been moving toward us at about 99.9% the speed of light. “After decades of studying these incredible cosmic explosions, we still don’t understand the details of how these jets work,” noted Elizabeth Hays, the Fermi project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Finding clues like this remarkable emission line will help scientists investigate this extreme environment more deeply.” The Fermi Gamma-ray Space Telescope is an astrophysics and particle physics partnership managed by Goddard. Fermi was developed in collaboration with the U.S. Department of Energy, with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the United States.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s Perseverance rover discovered “leopard spots” on a reddish rock nicknamed “Cheyava Falls” in Mars’ Jezero Crater in July 2024. Scientists think the spots may indicate that, billions of years ago, the chemical reactions in this rock could have supported microbial life; other explanations are being considered.NASA/JPL-Caltech/MSSS An annotated version of the image of “Cheyava Falls” indicates the markings akin to leopard spots, which have particularly captivated scientists, and the olivine in the rock. The image was captured by the WATSON instrument on NASA’s Perseverance Mars rover on July 18.NASA/JPL-Caltech/MSSS The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed. A vein-filled rock is catching the eye of the science team of NASA’s Perseverance rover. Nicknamed “Cheyava Falls” by the team, the arrowhead-shaped rock contains fascinating traits that may bear on the question of whether Mars was home to microscopic life in the distant past. Analysis by instruments aboard the rover indicates the rock possesses qualities that fit the definition of a possible indicator of ancient life. The rock exhibits chemical signatures and structures that could possibly have been formed by life billions of years ago when the area being explored by the rover contained running water. Other explanations for the observed features are being considered by the science team, and future research steps will be required to determine whether ancient life is a valid explanation. The rock — the rover’s 22nd rock core sample — was collected on July 21, as the rover explored the northern edge of Neretva Vallis, an ancient river valley measuring a quarter-mile (400 meters) wide that was carved by water rushing into Jezero Crater long ago. “Cheyava Falls” (left) shows the dark hole where NASA’s Perseverance took a core sample; the white patch is where the rover abraded the rock to investigate its composition. A rock nicknamed “Steamboat Mountain” (right) also shows an abrasion patch. This image was taken by Mastcam-Z on July 23.NASA/JPL-Caltech/ASU/MSSS NASA’s Perseverance used its Mastcam-Z instrument to view the “Cheyava Falls” rock sample within the rover’s drill bit. Scientists believe markings on the rock contain fascinating traits that may bear on the question of whether Mars was home to microscopic life in the distant past.NASA/JPL-Caltech/ASU/MSSS “We have designed the route for Perseverance to ensure that it goes to areas with the potential for interesting scientific samples,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “This trip through the Neretva Vallis riverbed paid off as we found something we’ve never seen before, which will give our scientists so much to study.” Multiple scans of Cheyava Falls by the rover’s SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instrument indicate it contains organic compounds. While such carbon-based molecules are considered the building blocks of life, they also can be formed by non-biological processes. “Cheyava Falls is the most puzzling, complex, and potentially important rock yet investigated by Perseverance,” said Ken Farley,Perseverance project scientist of Caltech in Pasadena. “On the one hand, we have our first compelling detection of organic material, distinctive colorful spots indicative of chemical reactions that microbial life could use as an energy source, and clear evidence that water — necessary for life — once passed through the rock. On the other hand, we have been unable to determine exactly how the rock formed and to what extent nearby rocks may have heated Cheyava Falls and contributed to these features.” NASA’s Perseverance rover used its Mastcam-Z instrument to capture this 360-degree panorama of a region on Mars called “Bright Angel,” where an ancient river flowed billions of years ago. “Cheyava Falls” was discovered in the area slightly right of center, about 361 feet (110 meters) from the rover.NASA/JPL-Caltech/ASU/MSSS Other details about the rock, which measures 3.2 feet by 2 feet (1 meter by 0.6 meters) and was named after a Grand Canyon waterfall, have intrigued the team, as well. How Rocks Get Their Spots In its search for signs of ancient microbial life, the Perseverance mission has focused on rocks that may have been created or modified long ago by the presence of water. That’s why the team homed in on Cheyava Falls. “This is the kind of key observation that SHERLOC was built for — to seek organic matter as it is an essential component of a search for past life,” said SHERLOC’s principal investigator Kevin Hand of NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission. Running the length of the rock are large white calcium sulfate veins. Between those veins are bands of material whose reddish color suggests the presence of hematite, one of the minerals that gives Mars its distinctive rusty hue. When Perseverance took a closer look at these red regions, it found dozens of irregularly shaped, millimeter-size off-white splotches, each ringed with black material, akin to leopard spots. Perseverance’s PIXL (Planetary Instrument for X-ray Lithochemistry) instrument has determined these black halos contain both iron and phosphate. As shown in this graphic, astrobiologists catalog a seven-step scale, called the CoLD (Confidence of Life Detection) scale, to research whether a sample could indicate life. This “Cheyava Falls” sample is an example of Step One: “Detect possible signal.” Much additional research must be conducted to learn more.NASA/Aaron Gronstal “These spots are a big surprise,” said David Flannery, an astrobiologist and member of the Perseverance science team from the Queensland University of Technology in Australia. “On Earth, these types of features in rocks are often associated with the fossilized record of microbes living in the subsurface.” Spotting of this type on sedimentary terrestrial rocks can occur when chemical reactions involving hematite turn the rock from red to white. Those reactions can also release iron and phosphate, possibly causing the black halos to form. Reactions of this type can be an energy source for microbes, explaining the association between such features and microbes in a terrestrial setting. In one scenario the Perseverance science team is considering, Cheyava Falls was initially deposited as mud with organic compounds mixed in that eventually cemented into rock. Later, a second episode of fluid flow penetrated fissures in the rock, enabling mineral deposits that created the large white calcium sulfate veins seen today and resulting in the spots. Another Puzzle Piece While both the organic matter and the leopard spots are of great interest, they aren’t the only aspects of the Cheyava Falls rock confounding the science team. They were surprised to find that these veins are filled with millimeter-size crystals of olivine, a mineral that forms from magma. The olivine might be related to rocks that were formed farther up the rim of the river valley and that may have been produced by crystallization of magma. If so, the team has another question to answer: Could the olivine and sulfate have been introduced to the rock at uninhabitably high temperatures, creating an abiotic chemical reaction that resulted in the leopard spots? “We have zapped that rock with lasers and X-rays and imaged it literally day and night from just about every angle imaginable,” said Farley. “Scientifically, Perseverance has nothing more to give. To fully understand what really happened in that Martian river valley at Jezero Crater billions of years ago, we’d want to bring the Cheyava Falls sample back to Earth, so it can be studied with the powerful instruments available in laboratories.” More Mission Information 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.

3 min read Meet NASA Interns Shaping Future of Open Science Intern Lena Young, whose work revolves around DEIA and open science, stands next to a NASA sign at NASA’s Earth Information Center in Washington, D.C. Photo courtesy of Lena Young Students at NASA’s Office of the Chief Science Data Officer (OCSDO) are working to promote open science during the summer 2024 internship session. Their projects fall across a variety of areas, including user experience, policy, and DEIA (Diversity, Equity, Inclusion, and Accessibility). Lena Young: Increasing DEIA Engagement Lena Young, a doctoral candidate in the Creative Leadership for Innovation and Change program at the University of the Virgin Islands in St. Thomas, envisions equitable space societies 100 – 300 years in the future as part of her dissertation. Her NASA internship project involves researching ways to make science more accessible for different groups and interacting with NASA leadership to assess how well they are engaging historically underserved or excluded communities. Young also worked with her mentors to find overlap between her internship project and her PhD work as a futurist. “In 30 years, once NASA has achieved their goals, what would open science look like?” Young said. “I want to see what different futures I can create for open science and DEIA engagement.” Becca Michelson: Advancing Policy Becca Michelson has a passion for increasing the availability of scientific information. A soon-to-be-graduate in physics and astronomy from Smith College in Northampton, Massachusetts, she was drawn to an internship role in researching the current state of open science policy for the OCSDO. By understanding the challenges and opportunities in this area, she’s helping NASA better support researchers in making their science accessible to all. “Open science makes this a more inclusive field, where if I’m an early career scientist, I can build on the science that other people who are experts in the field have done,” Michelson said. In the future, she hopes to implement open science principles into her own research in astronomy, drawing from the best practices she has learned at NASA. Salma Elsayed-Ali: Bridging Science, User Experience Salma Elsayed-Ali is on a mission to bridge the gap between science and usability. She recently completed her PhD in Information Science with a focus on Human-Computer Interaction from the University of Maryland, College Park. Her NASA internship project involves conducting UI/UX (User Interface/User Experience) research on some of the OCSDO’s scientific products, most notably the Open Science 101 online course. Elsayed-Ali became interested in open science during the height of the COVID-19 pandemic, when she conducted UI/UX research on open data sites that provided the public with real-time information about the spread of the virus. This experience sparked her interest in helping users reap the benefits of open science as part of an internship with NASA. In improving the OCSDO’s open science interfaces, Elsayed-Ali has acted as the product lead on a UI/UX research project for the first time. “I was drawn to this project as it was an opportunity to advocate for both end users and the advancement of open science,” Elsayed-Ali said. “I have really enjoyed brainstorming creative, practical solutions that enhance the user experience and simultaneously save the product team time and resources.” By helping open science at NASA to thrive, these interns are ushering in a future of greater access to data and scientific research.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.Credit: SpeedoUSA A supersonic airplane and a competitive swimmer have much more in common than people might realize; both have to contend with the slowing influence of drag. NASA’s Aeronautics Research Mission Directorate focuses primarily on improving flight efficiency and fluid dynamics, especially the forces of pressure and drag, which are the same for bodies moving through air as for bodies moving through water. Shortly after the 2004 Olympics, Los Angeles-based SpeedoUSA, also known as Speedo, asked NASA’s Langley Research Center to help design a swimsuit with reduced surface drag. The manufacturer sought a partnership with NASA because of the agency’s expertise in fluid dynamics. In competitive swimming, where every hundredth of a second counts, achieving the best possible drag reduction is crucially important. Researchers at NASA began flat plate testing of fabrics, using a small wind tunnel developed for earlier research on low-speed viscous drag reduction and collaborated over the next few years with Speedo to design the LZR Racer swimsuit. Researcher Corey Diebler inspects a model of the supersonic X-59 after a test in Langley Research Center’s 12 foot wind tunnel. Wind tunnel testing at Langley enabled Speedo’s LZR Racer to achieve its excellent underwater performance.NASA/David C. Bowman. NASA and Speedo performed tests on traditionally sewn seams, ultrasonically welded seams, and the fabric alone, which gave Speedo a baseline for reducing drag caused by seams and helped identify problem areas. NASA wind tunnel results helped Speedo create a bonding system that eliminates seams and reduces drag. The results also showed that a low-profile zipper ultrasonically bonded into the fabric inside the suit generated eight percent less drag in wind tunnel tests than a standard zipper. Low-profile seams and zippers were a crucial component in the LZR Racer, because the suit consists of multiple connecting fabric pieces—instead of just a few sewn pieces such as found in traditional suits—that provide extra compression for maximum efficiency. In March 2008, the LZR Racer made its mark on the world of competitive swimming. Athletes donning this innovative swimsuit shattered 13 world records, a testament to the power of collaboration between NASA and Speedo. While the original LZR Racer is no longer used in competition because of the advantage it gave wearers, its legacy lives on in today’s swimsuits approved by World Aquatics, the governing body for international competitive swimming.
