  1. 5 min read 5 Surprising NASA Heliophysics Discoveries Not Related to the Sun With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about of the solar system and beyond. Here are five examples of breakthroughs made by NASA heliophysics missions in other fields of science. This graphic shows missions in NASA’s Heliophysics Division fleet as of July 2024. NASA Thousands and Thousands of Comets The SOHO mission — short for Solar and Heliospheric Observatory, which is a joint mission between ESA (European Space Agency) and NASA — has a coronagraph that blocks out the Sun in order to see the Sun’s faint outer atmosphere, or corona. It turns out SOHO’s coronagraph also makes it easy to spot sungrazing comets, those that pass so close to the Sun that other observatories can’t see them against the brightness of our star. Before SOHO was launched in December 1995, fewer than 20 sungrazing comets were known. Since then, SOHO has discovered more than 5,000. The vast number of comets discovered using SOHO has allowed scientists to learn more about sungrazing comets and identify comet families, descended from ancestor comets that broke up long ago. Learn More Two sungrazing comets fly close to the Sun in these images captured by ESA/NASA’s SOHO (Solar and Heliospheric Observatory). They were the 3,999th and 4,000th comets discovered in SOHO images. ESA/NASA/SOHO/Karl Battams Dimming of a Supergiant In late 2019, the supergiant star Betelgeuse began dimming unexpectedly. Telescopes all over the world — ​​​​and around it — tracked these changes until a few months later when Betelgeuse appeared too close to the Sun to observe. That’s when NASA’s STEREO (Sun-watching Solar Terrestrial Relations Observatory (STEREO) came to the rescue. For several weeks in the middle of 2020, STEREO was the only observatory able to see Betelgeuse. At the time, the STEREO-A spacecraft was trailing behind Earth, at a vantage point where Betelgeuse was still far enough away from the Sun to be seen. This allowed astronomers to keep tabs on the star while it was out of view from Earth. STEREO’s observations revealed another unexpected dimming between June and August of 2020, when ground-based telescopes couldn’t view the star. Astronomers later concluded that these dimming episodes were caused by an ejection of mass from Betelgeuse — like a coronal mass ejection from our Sun but with about 400 times more mass — which obscured part of the star’s bright surface. Learn More The background image shows the star Betelgeuse as seen by the Heliospheric Imager aboard NASA’s STEREO (Solar Terrestrial Relations Observatory) spacecraft. The inset figure shows measurements of Betelgeuse’s brightness taken by different observatories from late 2018 to late 2020. STEREO’s observations, marked in red, revealed an unexpected dimming in mid-2020 when Betelgeuse appeared too close to the Sun for other observatories to view it. NASA/STEREO/HI (background); Dupree et al. (inset) The Glowing Surface of Venus NASA’s Parker Solar Probe studies the Sun’s corona up close — by flying through it. To dive into the Sun’s outer atmosphere, the spacecraft has flown past Venus several times, using the planet’s gravity to fling itself closer and closer to the Sun. On July 11, 2020, during Parker’s third Venus flyby, scientists used Parker’s wide-field imager, called WISPR, to try to measure the speed of the clouds that obscure Venus’ surface. Surprisingly, WISPR not only observed the clouds, it also saw through them to the surface below. The images from that flyby and the next (in 2021) revealed a faint glow from Venus’ hot surface in near-infrared light and long wavelengths of red (visible) light that maps distinctive features like mountainous regions, plains, and plateaus. Scientists aimed WISPR at Venus again on Nov. 6, 2024, during Parker’s seventh flyby, observing a different part of the planet than previous flybys. With these images, they’re hoping to learn more about Venus’ surface geology, mineralogy, and evolution. Learn More As Parker Solar Probe flew by Venus on its fourth flyby, it captured these images, strung into a video, showing bright and dark features on the nightside surface of the planet. NASA/APL/NRL The Brightest Gamma-Ray Burst You’ve heard of the GOAT. But have you heard of the BOAT? It stands for the “brightest of all time”, a gamma-ray burst discovered on Oct. 9, 2022. A gamma-ray burst is a brief but intense eruption of gamma rays in space, lasting from seconds to hours. This one, named GRB 221009A, glowed brilliantly for about 10 minutes in the constellation Sagitta before slowly fading. The burst was detected by dozens of spacecraft, including NASA’s Wind, which studies the perpetual flow of particles from the Sun, called the solar wind, just before it reaches Earth. Wind and NASA’s Fermi Gamma-Ray Space Telescope measured the brightness of GRB 221009A, showing that it was 70 times brighter than any other gamma-ray burst ever recorded by humans — solidifying its status as the BOAT. Learn More Astronomers think GRB 221009A represents the birth of a new black hole formed within the heart of a collapsing star. In this artist’s concept, the black hole drives powerful jets of particles traveling near the speed of light. The jets emit X-rays and gamma rays as they stream into space. NASA/Swift/Cruz deWilde A Volcano Blasts Its Way to Space NASA’s ICON (Ionospheric Connection Explorer) launched in 2019 to study how Earth’s weather interacts with weather from space. When the underwater Hunga Tonga-Hunga Ha‘apai volcano erupted on Jan. 15, 2022, ICON helped show that the volcano produced more than ash and tsunami waves — its effects reached the edge of space. In the hours after the eruption, ICON detected hurricane-speed winds in the ionosphere — Earth’s electrified upper atmospheric layer at the edge of space. ICON clocked the wind speeds at up to 450 miles per hour, making them the strongest winds the mission had ever measured below 120 miles altitude. The ESA Swarm mission revealed that these extreme winds altered an electric current in the ionosphere called the equatorial electrojet. After the eruption, the equatorial electrojet surged to five times its normal peak power and dramatically flipped direction. Scientists were surprised that a volcano could affect the electrojet so severely — something they’d only seen during a strong geomagnetic storm caused by an eruption from the Sun. Learn More The Hunga Tonga-Hunga Ha’apai eruption on Jan. 15, 2022, caused many effects, some illustrated here, that were felt around the world and even into space. Some of those effects, like extreme winds and unusual electric currents were picked up by NASA’s ICON (Ionospheric Connection Explorer) mission and ESA’s (the European Space Agency) Swarm.

Earth (ESD) Earth Home Explore Climate Change Science in Action Multimedia Data For Researchers 14 Min Read NASA’s Brad Doorn Brings Farm Belt Wisdom to Space-Age Agriculture This image shows corn cultivation patterns across the U.S. Midwest in 2020, with lands planted in corn marked in yellow. Credits: NASA Earth Observatory/ Lauren Dauphin Bradley Doorn grew up in his family’s trucking business, which hauled milk and animal feed across the sprawling plains of South Dakota. Home was Mitchell, a small town famous for its Corn Palace, where murals crafted from corn kernels and husks have adorned its facade since 1892—a tribute to the abundance of the surrounding farmland. Trucking was often grueling work for the family, the day breaking early and ending in headlights. Like farming, driving a truck wasn’t just a job; it was the engine of daily life, thrumming through nearly every conversation and decision. Brad loved the outdoors, and by the time he started college in the early 1980s, studying geological engineering felt like a natural fit. “I wanted to be out in the field somewhere, working under the big skies of the West,” Brad recalled. But in his sophomore year at the South Dakota School of Mines and Technology, the tuition money dried up. Dean Doorn, Brad Doorn’s father, stands beside a milk truck used in the family’s business of hauling milk across South Dakota in the 1960s and ’70s. Credit: B. Doorn Doorn found himself at a crossroads familiar to many in rural America: return to the certainty of a family trade or chart a new route. “That’s when the Army stepped in,” he said. The ROTC program offered a way to continue with school and a path into the world of remote sensing—a field that would come to define his career. Brad’s choice to join the Army would eventually place him at the forefront of a mapping revolution, equipping him to see and analyze Earth in ways never possible before the advent of satellites. But more than the technical skills, the military showed him the allure of a life anchored to mission and team. Even as his career took him far from Mitchell, Doorn would remain connected to his rural America roots. Today, he leads NASA’s agriculture programs within the agency’s Earth Science Division. “My family wasn’t made up of farmers, but farming was a part of everything growing up,” said Brad. “Even now, working with NASA, that connection to the land—the sense of how weather, crops, and people are tied together—it’s still in everything I do.” Amid the dazzle of NASA’s feats exploring the solar system and universe, it’s easy to miss the agency’s quiet work in fields of soy and wheat. But for more than 60 years, the agency has harnessed the power of its satellites to deliver crucial data on temperature, precipitation, crop yields, and more to farmers, policymakers, and food security experts worldwide.

Grid-like levees separate fields pre-planting. Louisiana is the third largest producer of rice in the U.S. Credit: NASA Earth Observatory/ Lauren Dauphin From orbit, satellites beam down streams of data—numbers and pixels that, when paired with farmers’ knowledge of the land, can guide growers as they adjust irrigation levels or plan for the next planting. But the satellites don’t just yield data; they tell stories that call for action, enabling nations to brace for droughts, floods, and the prospect of empty grain silos. “Under Brad’s guidance, NASA’s agriculture program has become a global leader for satellite-driven solutions, tackling food security and sustainability head-on,” said Lawrence Friedl, the senior engagement officer for NASA Earth Science. Reflecting on years of collaboration, he added: “I am so impressed and grateful for what he and his teams have accomplished.” Boots Meet Satellites in the First Gulf War Long before Brad began guiding NASA’s agricultural initiatives, he was already navigating tricky terrain, both literal and figurative, with satellite imagery. His career in remote sensing didn’t start with crops, but with the deserts of Iraq and Kuwait. As part of the Army’s 18th Airborne Corps, Brad led a company at Fort Bragg (now Fort Liberty) in North Carolina that had just returned from operations in the First Gulf War, in the early 1990s. “I loved being part of a unit, part of something bigger than just me,” Brad recalled. “It felt good to have that purpose and mission.” Far from the combat zone, Doorn’s company became cartographers of the invisible. Their task: merge data from the Landsat satellite with the gritty reality of desert warfare depicted on military maps. Brad Doorn, then a U.S. Army officer, sits at his desk during his early career in remote sensing. His military experience would later shape his work at NASA, applying satellite technology to real-world challenges. Credit: B. Doorn Landsat, a civilian satellite built by NASA and operated by the U.S. Geological Survey, could see what the soldiers on the ground could not. Its thermal infrared sensor—a camera with a penchant for temperature and moisture—read the desert floor like an ancient script, picking out the cold, soggy signature of mud lurking beneath the desert’s deceptive crust. Each pixel of satellite data became a brushstroke in a new kind of map, keeping tanks out of the mire and the missions on track. “It was so neat to see the remote sensing techniques I’d learned about in school actually making a difference,” Doorn said. With this knowledge, he helped guide his unit’s shift from analog maps—paper grids and grease pencils—to the emerging world of digital mapping, a leap that sharpened the military’s ability to read the landscape and steer clear of trouble. From Desert Muck to Farm Fields Brad’s military experience gave him an early look at how satellite data could address tangible, on-the-ground challenges. In the Army, he saw how integrating satellite data into military maps could offer soldiers critical information. That experience set the foundation for his later work at NASA, where he would help develop technology with lasting, practical impacts. Consider OpenET, a NASA-funded initiative that uses Landsat data to give farmers insights into water use and irrigation needs at field scale. The ET in OpenET stands not for the little alien who phoned home, but for evapotranspiration. It’s a combination of water evaporating from the ground and water released by plants into the air. The program relies on the same thermal technology Doorn used during the Gulf War. Just as cooler, wetter areas in the desert hint at muddy spots, cooler patches in farm fields show where there’s more moisture or plants are releasing more water. These data are key to managing water resources wisely and keeping crops healthy. “OpenET has transformed our understanding of water demand,” explained Doorn. To better manage water, state officials and farmers in California are using satellite data through OpenET to track evapotranspiration. Here, the colors represent total evapotranspiration for 2023 as the equivalent depth of water in millimeters. Dark blue regions have higher evapotranspiration rates, such as in the Central Valley. Credit: NASA Earth Observatory using openetdata.org In the late 2000s, when a new generation of Landsat satellites was being planned, the thermal infrared imagers were initially left off the drawing board. “Landsat 8’s design caused a lot of consternation in some Western states that were beginning to use the instrument for measuring and monitoring water use,” said Tony Willardson, the executive director of the Western States Water Council, a government entity that advises western governors on water policy. Brad played a key role in conveying to NASA the critical need for this technology, both for agriculture and water management, Willardson said. The thermal imager was eventually reinstated and has since “helped to close a gap in western water management.” “A lot of the technologies that we are using more and more were developed by NASA,” said Willardson. “We need NASA to be doing even more in Earth science.” Sowing Global Food Stability from Space Brad ended up serving in the Army for nearly a decade. “You hit that 10-year mark in the military, and you sort of have to decide if you’re staying in for 20 or if you’re getting out,” said Brad. “My wife, Kristen, was able to manage her career as a registered dietician through the first four moves in six years, but eventually it was too much. So, I told her: ‘Your choice. You decide where we go next.’” She chose southern Pennsylvania to be closer to her family. Brad was 32 years old, and the couple had two small children at the time—one of whom had had open-heart surgery at 6 weeks old to fix a heart defect. They would go on to have another child. In the late 1990s, within a few years of leaving the military, Doorn found himself someplace he had never imagined: sitting behind a desk at the U.S. Department of Agriculture. For a boy who had grown up driving trucks across the plains of South Dakota—who had vowed never to work in an office, much less live east of the Mississippi—this was an unexpected detour. But he had long since learned that the best paths are often the ones you don’t see coming. At USDA, he moved forward not with a grand plan, but with an instinctive trust in where curiosity and challenge might lead. He rose through the ranks, from a programmer to directing the agency’s international food production analysis program. He was increasingly driven by a conviction that satellite data, if used the right way, could transform how we see the land and the way we feed the world. While at USDA, and later at NASA, which he joined in 2009, Brad was instrumental in developing and overseeing the Global Agricultural Monitoring (GLAM) system. This real-time interactive satellite platform delivers massive amounts of ready-to-use satellite data directly to USDA crop analysts, eliminating the burden of data processing and enabling them to focus on rapid crop analysis across the globe. It was a pioneering tool, said Inbal Becker-Reshef, a research professor at University of Maryland’s Department of Geographical Sciences, who played a central role in developing the GLAM system. At a 2022 Kansas gathering, Brad Doorn presents to farmers about NASA’s Earth Science Division and its activities supporting agriculture. Credit: A. Whitcraft GLAM set the stage for GEOGLAM, a separate, international initiative launched in 2011 by agriculture ministers from the G20—a group of the world’s major economies—partly as a response to global food price volatility. GEOGLAM, which stands for Group on Earth Observations Global Agricultural Monitoring, uses satellite data to monitor global crop conditions, from drought stress to excessive rain, around the world. Joseph Glauber, a former USDA chief economist, noted that there was initial uncertainty within USDA about the initiative’s longevity, but he credited Brad’s background with rallying support. Today, GEOGLAM’s monthly crop assessments, produced by over 40 organizations including USDA and NASA, serve as a global consensus on crop conditions, helping governments and humanitarian organizations anticipate food shortages. “Even today, the G20 points to GEOGLAM and its sister initiative, the Agricultural Market Information System—which tracks how crop conditions affect markets—as major successes,” Glauber said. Harvesting Data Amid Conflict Doorn’s work crosses continents. When war broke out between Russia and Ukraine in 2022, it rattled global food markets. The Ukrainian government turned to NASA Harvest—a global food security and agriculture consortium led by the University of Maryland and funded by NASA—for help. As manager of NASA’s agriculture program, Brad was a driving force behind the launch of NASA Harvest in 2017, envisioning it as a program that would harness satellite data to provide timely, actionable insights for global agriculture. From orbit, satellites could observe the sown and the harvested wheat, sunflowers, and barley, offering some of the only reliable estimates for fields in the war zone. Satellite imagery revealed that, despite the conflict, more cropland had been planted and harvested in Ukraine than anyone had expected, a finding that helped stabilize volatile global food prices. “Brad and the team recognized that providing that type of rapid agricultural assessment for policy support is what NASA Harvest exists for,” said Becker-Reshef, who is the director of the consortium. NASA Harvest’s reach stretches well beyond Europe. In sub-Saharan Africa, the consortium collaborates with local and international partners, tracking the health of crops and the creeping spread of drought. This information helps equip governments, aid organizations, and farmers to act before disaster strikes, making each data point a crucial defense against hunger. NASA Harvest has since been joined by NASA Acres, founded in 2023 to provide satellite data and tools that help farmers make well-informed decisions for healthier crops and soil in the United States. One project, for example, involves working with farmers in Illinois to manage nitrogen use more effectively, leveraging satellite data to enhance crop yields while reducing environmental impact. This image shows corn cultivation patterns across the U.S. Midwest in 2020, with lands planted in corn marked in yellow. The map was built from the Cropland Data Layer product provided by the National Agricultural Statistics Service, which includes data from the USGS National Land Cover Database and from satellites such as Landsat 8. Credit: NASA Earth Observatory/ Lauren Dauphin Friedl noted that Doorn understands the missions of both NASA and the USDA, and with his agricultural roots, he knows the needs of farmers and agricultural businesses firsthand. “Often in meetings, Brad would remind us that the margins for a farmer are in the pennies,” Friedl said. “They wouldn’t be able to afford remote sensing,” so making sure NASA’s satellite information was free and accessible was that much more important. “It’s hard to imagine that NASA would have the agriculture program it does without somebody like Brad continuing to advocate and push for this to exist,” said Alyssa Whitcraft, the director of NASA Acres. “He knows how critical it is for satellite data to be accessible and useful to those on the ground. He makes sure we never lose sight of that.” An Emissary Between Worlds Colleagues say Doorn’s strength lies in his ability to bridge worlds, whether it’s making connections between agencies like NASA and USDA, or connecting such agencies to state water councils or farming communities. His fluency in translating complex science into simple terms makes him equally at ease in whichever world he finds himself. “There’s NASA language and there’s farm language,” says Lance Lillibridge, who farms about 1,400 acres of corn and soybeans in Benton County, Iowa, and has helped lead the Iowa Corn Growers Association. “Sometimes you need an interpreter, and Brad’s that guy.” He recalled a meeting where some farmers were skeptical, wary of NASA’s “big brother” eyes in the sky, “but Brad had a way of putting people at ease, keeping everyone focused on the shared goal of better data for better decisions.” Brad Doorn speaks during NASA’s “Space for Ag” roadshow in Iowa, July 2023, highlighting NASA’s role in supporting sustainable farming practices. Credit: N. Pepper “One of my favorite memories of Brad,” said Forrest Melton, the OpenET project scientist at NASA’s Ames Research Center, “is an afternoon spent visiting with farmers in western Nebraska, drinking iced tea and talking with them about the challenges facing their family farm.” Colleagues describe Brad as a nearly unflappable guide, one who knows the agricultural landscape so well that he makes the impossible seem manageable. They say his calm, approachable style, paired with a ready smile, puts people at ease whether in Washington conference rooms or Midwestern barns. And he listens closely to understand where there may be opportunities to help. “Few people in the water and agriculture communities, from the small-scale farmer to the federal government appointee, aren’t familiar with some aspect of the work Brad has enabled over the decades,” said Sarah Brennan, a former deputy program manager for NASA’s water resources programs. “He has supported the development of some of the greatest advancements in using remote sensing in these communities.” It’s About the People and the Team Doorn’s leadership is less about issuing directives, colleagues say, and more about cultivating growth—in crops, in data systems, and in people. Like a farmer tending to his fields, he nurtures the potential in every project and person he encounters. “Almost everyone who has worked for Brad can point back to the opportunities he provided them that launched their successful careers,” said Brennan. Over the years, he’s added layers to this work of creating paths for others to succeed: as president of the American Society of Photogrammetry and Remote Sensing, as an adjunct professor at Penn State, and as a youth basketball league director. “What I’ve learned, probably in the military and I’ve carried it forward, is that it’s the people that matter,” Brad said. “I had great mentors who believed it’s just as important to help others grow as it is to meet the day’s demands. Those roles shift your focus toward the people around you, and often, the more you give of your time, the more you end up getting back.” Young Brad Doorn (front center) stands with his siblings, capturing a family moment in 1960s South Dakota. His youngest brother isn’t pictured. Credit: B. Doorn It has been a long journey from hauling milk and animal feed across the South Dakota plains to surveying them now as a scientist. The tools of his career have changed—from truck routes to satellite orbits, from paper maps to digital data—but his mission remains the same: helping farmers feed the world. “Growing up in South Dakota, I saw firsthand the challenges farmers face. Today, I’m proud to help provide the tools and data that can make a real difference in their lives,” Doorn added. “Whether it’s a farmer, an economist, or a military analyst, if you give them the right tools, they’ll take them to places you never even thought about. That’s what excites me—seeing where they go.” By Emily DeMarco NASA’s Earth Science Division, Headquarters Share Details Last Updated Nov 20, 2024 Related Terms Earth People of NASA Keep Exploring Discover More Topics From NASA Earth Your home.

  4. 5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A prototype of a robot designed to explore subsurface oceans of icy moons is reflected in the water’s surface during a pool test at Caltech in September. Conducted by NASA’s Jet Propulsion Laboratory, the testing showed the feasibility of a mission concept for a swarm of mini swimming robots.NASA/JPL-Caltech In a competition swimming pool, engineers tested prototypes for a futuristic mission concept: a swarm of underwater robots that could look for signs of life on ocean worlds. When NASA’s Europa Clipper reaches its destination in 2030, the spacecraft will prepare to aim an array of powerful science instruments toward Jupiter’s moon Europa during 49 flybys, looking for signs that the ocean beneath the moon’s icy crust could sustain life. While the spacecraft, which launched Oct. 14, carries the most advanced science hardware NASA has ever sent to the outer solar system, teams are already developing the next generation of robotic concepts that could potentially plunge into the watery depths of Europa and other ocean worlds, taking the science even further. This is where an ocean-exploration mission concept called SWIM comes in. Short for Sensing With Independent Micro-swimmers, the project envisions a swarm of dozens of self-propelled, cellphone-size swimming robots that, once delivered to a subsurface ocean by an ice-melting cryobot, would zoom off, looking for chemical and temperature signals that could indicate life. Dive into underwater robotics testing with NASA’s futuristic SWIM (Sensing With Independent Micro-swimmers) concept for a swarm of miniature robots to explore subsurface oceans on icy worlds, and see a JPL team testing a prototype at a pool at Caltech in Pasadena, California, in September 2024. NASA/JPL-Caltech “People might ask, why is NASA developing an underwater robot for space exploration? It’s because there are places we want to go in the solar system to look for life, and we think life needs water. So we need robots that can explore those environments — autonomously, hundreds of millions of miles from home,” said Ethan Schaler, principal investigator for SWIM at NASA’s Jet Propulsion Laboratory in Southern California. Under development at JPL, a series of prototypes for the SWIM concept recently braved the waters of a 25-yard (23-meter) competition swimming pool at Caltech in Pasadena for testing. The results were encouraging. SWIM Practice The SWIM team’s latest iteration is a 3D-printed plastic prototype that relies on low-cost, commercially made motors and electronics. Pushed along by two propellers, with four flaps for steering, the prototype demonstrated controlled maneuvering, the ability to stay on and correct its course, and a back-and-forth “lawnmower” exploration pattern. It managed all of this autonomously, without the team’s direct intervention. The robot even spelled out “J-P-L.” Just in case the robot needed rescuing, it was attached to a fishing line, and an engineer toting a fishing rod trotted alongside the pool during each test. Nearby, a colleague reviewed the robot’s actions and sensor data on a laptop. The team completed more than 20 rounds of testing various prototypes at the pool and in a pair of tanks at JPL. “It’s awesome to build a robot from scratch and see it successfully operate in a relevant environment,” Schaler said. “Underwater robots in general are very hard, and this is just the first in a series of designs we’d have to work through to prepare for a trip to an ocean world. But it’s proof that we can build these robots with the necessary capabilities and begin to understand what challenges they would face on a subsurface mission.” Swarm Science A model of the final envisioned SWIM robot, right, sits beside a capsule holding an ocean-composition sensor. The sensor was tested on an Alaskan glacier in July 2023 through a JPL-led project called ORCAA (Ocean Worlds Reconnaissance and Characterization of Astrobiological Analogs). The wedge-shaped prototype used in most of the pool tests was about 16.5 inches (42 centimeters) long, weighing 5 pounds (2.3 kilograms). As conceived for spaceflight, the robots would have dimensions about three times smaller — tiny compared to existing remotely operated and autonomous underwater scientific vehicles. The palm-size swimmers would feature miniaturized, purpose-built parts and employ a novel wireless underwater acoustic communication system for transmitting data and triangulating their positions. Digital versions of these little robots got their own test, not in a pool but in a computer simulation. In an environment with the same pressure and gravity they would likely encounter on Europa, a virtual swarm of 5-inch-long (12-centimeter-long) robots repeatedly went looking for potential signs of life. The computer simulations helped determine the limits of the robots’ abilities to collect science data in an unknown environment, and they led to the development of algorithms that would enable the swarm to explore more efficiently. The simulations also helped the team better understand how to maximize science return while accounting for tradeoffs between battery life (up to two hours), the volume of water the swimmers could explore (about 3 million cubic feet, or 86,000 cubic meters), and the number of robots in a single swarm (a dozen, sent in four to five waves). In addition, a team of collaborators at Georgia Tech in Atlanta fabricated and tested an ocean composition sensor that would enable each robot to simultaneously measure temperature, pressure, acidity or alkalinity, conductivity, and chemical makeup. Just a few millimeters square, the chip is the first to combine all those sensors in one tiny package. Of course, such an advanced concept would require several more years of work, among other things, to be ready for a possible future flight mission to an icy moon. In the meantime, Schaler imagines SWIM robots potentially being further developed to do science work right here at home: supporting oceanographic research or taking critical measurements underneath polar ice.

  5. 5 Min Read Making Mars’ Moons: Supercomputers Offer ‘Disruptive’ New Explanation A NASA study using a series of supercomputer simulations reveals a potential new solution to a longstanding Martian mystery: How did Mars get its moons? The first step, the findings say, may have involved the destruction of an asteroid. The research team, led by Jacob Kegerreis, a postdoctoral research scientist at NASA’s Ames Research Center in California’s Silicon Valley, found that an asteroid passing near Mars could have been disrupted – a nice way of saying “ripped apart” – by the Red Planet’s strong gravitational pull. The team’s simulations show the resulting rocky fragments being strewn into a variety of orbits around Mars. More than half the fragments would have escaped the Mars system, but others would’ve stayed in orbit. Tugged by the gravity of both Mars and the Sun, in the simulations some of the remaining asteroid pieces are set on paths to collide with one another, every encounter further grinding them down and spreading more debris. Many collisions later, smaller chunks and debris from the former asteroid could have settled into a disk encircling the planet. Over time, some of this material is likely to have clumped together, possibly forming Mars’ two small moons, Phobos and Deimos. To assess whether this was a realistic chain of events, the research team explored hundreds of different close encounter simulations, varying the asteroid’s size, spin, speed, and distance at its closest approach to the planet. The team used their high-performance, open-source computing code, called SWIFT, and the advanced computing systems at Durham University in the United Kingdom to study in detail both the initial disruption and, using another code, the subsequent orbits of the debris. In a paper published Nov. 20 in the journal Icarus, the researchers report that, in many of the scenarios, enough asteroid fragments survive and collide in orbit to serve as raw material to form the moons. “It’s exciting to explore a new option for the making of Phobos and Deimos – the only moons in our solar system that orbit a rocky planet besides Earth’s,” said Kegerreis. “Furthermore, this new model makes different predictions about the moons’ properties that can be tested against the standard ideas for this key event in Mars’ history.” Two hypotheses for the formation of the Martian moons have led the pack. One proposes that passing asteroids were captured whole by Mars’ gravity, which could explain the moons’ somewhat asteroid-like appearance. The other says that a giant impact on the planet blasted out enough material – a mix of Mars and impactor debris – to form a disk and, ultimately, the moons. Scientists believe a similar process formed Earth’s Moon. The latter explanation better accounts for the paths the moons travel today – in near-circular orbits that closely align with Mars’ equator. However, a giant impact ejects material into a disk that, mostly, stays close to the planet. And Mars’ moons, especially Deimos, sit quite far away from the planet and probably formed out there, too. “Our idea allows for a more efficient distribution of moon-making material to the outer regions of the disk,” said Jack Lissauer, a research scientist at Ames and co-author on the paper. “That means a much smaller ‘parent’ asteroid could still deliver enough material to send the moons’ building blocks to the right place.” It’s exciting to explore a new option for the making of Phobos and Deimos – the only moons in our solar system that orbit a rocky planet besides Earth’s. Jacob Kegerreis Postdoctoral research scientist at NASA’s Ames Research Center Testing different ideas for the formation of Mars’ moons is the primary goal of the upcoming Martian Moons eXploration (MMX) sample return mission led by JAXA (Japan Aerospace Exploration Agency). The spacecraft will survey both moons to determine their origin and collect samples of Phobos to bring to Earth for study. A NASA instrument on board, called MEGANE – short for Mars-moon Exploration with GAmma rays and Neutrons – will identify the chemical elements Phobos is made of and help select sites for the sample collection. Some of the samples will be collected by a pneumatic sampler also provided by NASA as a technology demonstration contribution to the mission. Understanding what the moons are made of is one clue that could help distinguish between the moons having an asteroid origin or a planet-plus-impactor source. Before scientists can get their hands on a piece of Phobos to analyze, Kegerreis and his team will pick up where they left off demonstrating the formation of a disk that has enough material to make Phobos and Deimos. “Next, we hope to build on this proof-of-concept project to simulate and study in greater detail the full timeline of formation,” said Vincent Eke, associate professor at the Institute for Computational Cosmology at Durham University and a co-author on the paper. “This will allow us to examine the structure of the disk itself and make more detailed predictions for what the MMX mission could find.” For Kegerreis, this work is exciting because it also expands our understanding of how moons might be born – even if it turns out that Mars’ own formed by a different route. The simulations offer a fascinating exploration, he says, of the possible outcomes of encounters between objects like asteroids and planets. These events were common in the early solar system, and simulations could help researchers reconstruct the story of how our cosmic backyard evolved. This research is a collaborative effort between Ames and Durham University, supported by the Institute for Computational Cosmology’s Planetary Giant Impact Research group. The simulations used were run using the open-source SWIFT code, carried out on the DiRAC (Distributed Research Utilizing Advanced Computing) Memory Intensive service (“COSMA”), hosted by Durham University on behalf of the DiRAC High-Performance Computing facility.

  6. 5 min read NASA’s Swift Reaches 20th Anniversary in Improved Pointing Mode After two decades in space, NASA’s Neil Gehrels Swift Observatory is performing better than ever thanks to a new operational strategy implemented earlier this year. The spacecraft has made great scientific strides in the years since scientists dreamed up a new way to explore gamma-ray bursts, the most powerful explosions in the universe. “The idea for Swift was born during a meeting in a hotel basement in Estes Park, Colorado, in the middle of a conference,” said John Nousek, the Swift mission director at Pennsylvania State University in State College. “A bunch of astrophysicists got together to brainstorm a mission that could help us solve the problem of gamma-ray bursts, which were a very big mystery at the time.” Watch to learn how NASA’s Neil Gehrels Swift Observatory got its name. NASA’s Goddard Space Flight Center Gamma-ray bursts occur all over the sky without warning, with about one a day detected on average. Astronomers generally divide these bursts into two categories. Long bursts produce an initial pulse of gamma rays for two seconds or more and occur when the cores of massive stars collapse to form black holes. Short bursts last less than two seconds and are caused by the mergers of dense objects like neutron stars. But in 1997, at the time of that basement meeting, the science community disagreed over the origin models for these events. Astronomers needed a satellite that could move quickly to locate them and move to point additional instruments at their positions. What developed was Swift, which launched Nov. 20, 2004, from Complex 17A at what is now Cape Canaveral Space Force Station in Florida. Originally called the Swift Observatory for its ability to quickly point at cosmic events, the mission team renamed the spacecraft in 2018 after its first principal investigator Neil Gehrels. Swift uses several methods for orienting and stabilizing itself in space to study gamma-ray bursts. Sensors that detect the Sun’s location and the direction of Earth’s magnetic field provide the spacecraft with a general sense of its location. Then, a device called a star tracker looks at stars and tells the spacecraft how to maneuver to keep the observatory precisely pointed at the same position during long observations. Swift uses three spinning gyroscopes, or gyros, to carry out those moves along three axes. The gyros were designed to align at right angles to each other, but once in orbit the mission team discovered they were slightly misaligned. The flight operations team developed a strategy where one of the gyros worked to correct the misalignment while the other two pointed Swift to achieve its science goals. The team wanted to be ready in case one of the gyros failed, however, so in 2009 they developed a plan to operate Swift using just two. Swift orbits above Earth in this artist’s concept. NASA’s Goddard Space Flight Center Conceptual Image Lab Any change to the way a telescope operates once in space carries risk, however. Since Swift was working well, the team sat on their plan for 15 years. Then, in July 2023, one of Swift’s gyros began working improperly. Because the telescope couldn’t hold its pointing position accurately, observations got progressively blurrier until the gyro failed entirely in March 2024. “Because we already had the shift to two gyros planned out, we were able to quickly and thoroughly test the procedure here on the ground before implementing it on the spacecraft,” said Mark Hilliard, Swift’s flight operations team lead at Omitron, Inc. and Penn State. “Actually, scientists have commented that the accuracy of Swift’s pointing is now better than it was since launch, which is really encouraging.” For the last 20 years, Swift has contributed to groundbreaking results — not only for gamma-ray bursts but also for black holes, stars, comets, and other cosmic objects. “After all this time, Swift remains a crucial part of NASA’s fleet,” said S. Bradley Cenko, Swift’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The satellite’s abilities have helped pioneer a new era of astrophysics called multimessenger astronomy, which is giving us a more well-rounded view of how the universe works. We’re looking forward to all Swift has left to teach us.” Swift is a key part of NASA’s strategy to look for fleeting and unpredictable changes in the sky with a variety of telescopes that use different methods of studying the cosmos. Goddard manages the Swift mission in collaboration with Penn State, the Los Alamos National Laboratory in New Mexico, and Northrop Grumman Space Systems in Dulles, Virginia. Other partners include the University of Leicester and Mullard Space Science Laboratory in the United Kingdom, Brera Observatory in Italy, and the Italian Space Agency.

    Gateway Tops Off

    Technicians carefully install a piece of equipment to house Gateway’s xenon fuel tanks, part of its advanced electric propulsion system. Gateway’s Power and Propulsion Element, which will make the lunar space station the most powerful solar electric spacecraft ever flown, recently received the xenon and liquid fuel tanks for its journey to and around the Moon. Technicians in Palo Alto, California carefully install a piece of equipment that will house the tanks. Once fully assembled and launched to lunar orbit, the Power and Propulsion Element’s roll-out solar arrays – together about the size of an American football field endzone – will harness the Sun’s energy to energize xenon gas and produce the thrust to get Gateway to the Moon’s orbit where it will await the arrival of its first crew on the Artemis IV mission. The Power and Propulsion Element will also carry the European Radiation Sensors Array science experiment provided by ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency), one of three Gateway science experiments that will study solar and cosmic radiation. The little understood phenomenon is a chief concern for humans and hardware journeying to deep-space destinations like Mars and beyond. The Power and Propulsion Element is managed out of NASA’s Glenn Research Center in Cleveland, Ohio and built by Maxar Space Systems of Palo Alto, California. Hardware for the Gateway space station’s Power and Propulsion element, including its primary structure and fuel tanks ready for assembly, are shown at Maxar Space Systems in Palo Alto, California.Maxar Space Systems An artist’s rendering of the Gateway space station’s Power and Propulsion Element.NASA/Alberto Bertolin A type of advanced electric propulsion system thruster that will be used on Gateway glows blue as it emits ionized xenon gas during testing at NASA’s Glenn Research Center.NASA An artist’s rendering of European Radiation Sensor Array science experiment that will study both radiation and lunar dust.

  9. Imagine designing technology that can survive on the Moon for up to a decade, providing a continuous energy supply. NASA selected three companies to develop such systems, aimed at providing a power source at the Moon’s South Pole for Artemis missions. Three companies were awarded contracts in 2022 with plans to test their self-sustaining solar arrays at the Johnson Space Center’s Space Environment Simulation Laboratory (SESL) in Houston, specifically in Chamber A in building 32. The prototypes tested to date have undergone rigorous evaluations to ensure the technology can withstand the harsh lunar environment and deploy the solar array effectively on the lunar surface. The Honeybee Robotics prototype during lunar VSAT (Vertical Solar Array Technology) testing inside Chamber A at NASA’s Johnson Space Center in Houston.NASA/David DeHoyos The Astrobotic Technology prototype during lunar VSAT testing inside Chamber A at Johnson Space Center. NASA/James Blair In the summer of 2024, both Honeybee Robotics, a Blue Origin company from Altadena, California and Astrobotic Technology from Pittsburgh, Pennsylvania put their solar array concepts to the test in Chamber A. Each company has engineered a unique solution to design the arrays to withstand the harsh lunar environment and extreme temperature swings. The data collected in the SESL will support refinement of requirements and the designs for future technological advancements with the goal to deploy at least one of the systems near the Moon’s South Pole. The contracts for this initiative are part of NASA’s VSAT (Vertical Solar Array Technology) project, aiming to support the agency’s long-term lunar surface operations. VSAT is under the Space Technology Mission Directorate Game Changing Development program and led by the Langley Research Center in Hampton, Virginia, in collaboration with Glenn Research Center in Cleveland. “We foresee the Moon as a hub for manufacturing satellites and hardware, leveraging the energy required to launch from the lunar surface,” said Jim Burgess, VSAT lead systems engineer. “This vision could revolutionize space exploration and industry.” Built in 1965, the SESL initially supported the Gemini and Apollo programs but was adapted to conduct testing for other missions like the Space Shuttle Program and Mars rovers, as well as validate the design of the James Webb Space Telescope. Today, it continues to evolve to support future Artemis exploration. Johnson’s Front Door initiative aims to solve the challenges of space exploration by opening opportunities to the public and bringing together bold and innovative ideas to explore new destinations. “The SESL is just one of the hundreds of unique capabilities that we have here at Johnson,” said Molly Bannon, Johnson’s Innovation and Strategy specialist. “The Front Door provides a clear understanding of all our capabilities and services, the ways in which our partners can access them, and how to contact us. We know that we can go further together with all our partners across the entire space ecosystem if we bring everyone together as the hub of human spaceflight.” Chamber A remains as one of the largest thermal vacuum chambers of its kind, with the unique capability to provide extreme deep space temperature conditions down to as low as 20 Kelvin. This allows engineers to gather essential data on how technologies react to the Moon’s severe conditions, particularly during the frigid lunar night where the systems may need to survive for 96 hours in darkness. “Testing these prototypes will help ensure more safe and reliable space mission technologies,” said Chuck Taylor, VSAT project manager. “The goal is to create a self-sustaining system that can support lunar exploration and beyond, making our presence on the Moon not just feasible but sustainable.” The power generation systems must be self-aware to manage outages and ensure survival on the lunar surface. These systems will need to communicate with habitats and rovers and provide continuous power and recharging as needed. They must also deploy on a curved surface, extend 32 feet high to reach sunlight, and retract for possible relocation. “Generating power on the Moon involves numerous lessons and constant learning,” said Taylor. “While this might seem like a technical challenge, it’s an exciting frontier that combines known technologies with innovative solutions to navigate lunar conditions and build a dynamic and robust energy network on the Moon.” Watch the video below to explore the capabilities and scientific work enabled by the thermal testing conducted in Johnson’s Chamber A facility.

The large cargo landers will have the capability to land approximately 26,000 to 33,000 pounds (12-15 metric tons) of large, heavy payload on the lunar surface. Credit: SpaceX/Blue Origin NASA, along with its industry and international partners, is preparing for sustained exploration of the lunar surface with the Artemis campaign to advance science and discovery for the benefit of all. As part of that effort, NASA intends to award Blue Origin and SpaceX additional work under their existing contracts to develop landers that will deliver large pieces of equipment and infrastructure to the lunar surface. NASA expects to assign demonstration missions to current human landing system providers, SpaceX and Blue Origin, to mature designs of their large cargo landers following successful design certification reviews. The assignment of these missions builds on the 2023 request by NASA for the two companies to develop cargo versions of their crewed human landing systems, now in development for Artemis III, Artemis IV, and Artemis V. “NASA is planning for both crewed missions and future services missions to the Moon beyond Artemis V,” said Stephen D. Creech, assistant deputy associate administrator for technical, Moon to Mars Program Office. “The Artemis campaign is a collaborative effort with international and industry partners. Having two lunar lander providers with different approaches for crew and cargo landing capability provides mission flexibility while ensuring a regular cadence of Moon landings for continued discovery and scientific opportunity.” NASA plans for at least two delivery missions with large cargo. The agency intends for SpaceX’s Starship cargo lander to deliver a pressurized rover, currently in development by JAXA (Japan Aerospace Exploration Agency), to the lunar surface no earlier than fiscal year 2032 in support of Artemis VII and later missions. The agency expects Blue Origin to deliver a lunar surface habitat no earlier than fiscal year 2033. “Based on current design and development progress for both crew and cargo landers and the Artemis mission schedules for the crew lander versions, NASA assigned a pressurized rover mission for SpaceX and a lunar habitat delivery for Blue Origin,” said Lisa Watson-Morgan, program manager, Human Landing System, at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These large cargo lander demonstration missions aim to optimize our NASA and industry technical expertise, resources, and funding as we prepare for the future of deep space exploration.” SpaceX will continue cargo lander development and prepare for the Starship cargo mission under Option B of the NextSTEP Appendix H contract. Blue Origin will conduct its cargo lander work and demonstration mission under NextSTEP Appendix P. NASA expects to issue an initial request for proposals to both companies in early 2025. With the Artemis campaign, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future exploration of Mars. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with commercial human landing systems, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

  12. Following eight months of intense research, design, and prototyping, six university teams presented their “Inflatable Systems for Lunar Operations” concepts to a panel of judges at NASA’s 2024 Breakthrough, Innovative and Game-Changing (BIG) Idea Challenge forum. The challenge, funded by NASA’s Space Technology Mission Directorate and Office of STEM Engagement, seeks novel ideas from higher education on a new topic each year and supports the agency’s Lunar Surface Innovation Initiative in developing new approaches and innovative technologies to pave the way for successful exploration on the surface of the Moon. This year, teams were asked to develop low Size, Weight, and Power inflatable technologies, structures and systems that could benefit future Artemis missions to the Moon and beyond. Taking top honors at this year’s forum receiving the Artemis Award was Northwestern University with National Aerospace Corporation & IMS Engineered Products, with their concept titled METALS: Metallic Expandable Technology for Artemis Lunar Structures. The Artemis Award is given to the team whose concept has the best potential to contribute to and be integrated into an Artemis mission.  The Northwestern University BIG Idea Challenge team developed METALS, an inflatable metal concept for long-term storage of cryogenic fluid on the Moon.

  13. 2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The thermal protection system on the outside of the space shuttle included hundreds of ceramic tiles custom made for the orbiter. These reflected heat off the shuttle’s outside surface during atmospheric re-entry and were an inspiration for the ceramic ingredients in Super Therm. Credit: NASA Without proper insulation, sunlight can make buildings feel like ovens. In the late 1980s, Joseph Pritchett aimed to solve this problem by developing a coating for building insulation. He knew of NASA’s experience with thermal testing, particularly with ceramics, which have several uses for the agency. Their heat-resistant properties make them excellent materials for spacecraft reentry shields, and their durability is perfect for airplane components. Pritchett thought by infusing paints with both insulating ceramic compounds and tough, resilient polymers, he could develop an insulation coating with the best features of both. Pritchett contacted the materials lab at NASA’s Marshall Space Flight Center in Huntsville, Alabama, through the center’s Technology Transfer Office. The facility had many ways to test heat-resistant materials, and the Marshall engineers and research scientists provided Pritchett with lists of material compounds to test for his insulation coating. Super Therm has been applied in several places, including handrails on the Hoover Dam Bypass Bridge over the Colorado River. The selection of its makeup of ceramic and polymeric materials was assisted by NASA scientists.Credit: Superior Products InternationaI II, LLC Over a period of six years, Pritchett tested every compound on the lists NASA provided, narrowing down the potential compounds until he found the ideal insulation. Pritchett founded Superior Products International II, Inc. of Shawnee, Kansas, in 1995. His product, dubbed Super Therm, is a composite of both ceramic and polymeric materials. In 2011, when tested by Oak Ridge National Laboratory in Tennessee, Pritchett’s product proved successful in saving energy when cooling homes. The engineers at Marshall played a pivotal role in Super Therm’s development, as their knowledge was key to finding the right ceramic material. In addition to insulation for buildings, the material has been used in other industrial applications, such as keeping equipment like tanks and pumps cool on oil rigs. Pritchett’s Super Therm is yet another example of how NASA’s Technology Transfer Program within the agency’s Space Technology Mission Directorate drives innovation in commercial industry.

I love working across the division, and with the center and the broader community, to engage with diverse competent teams and realize their potential in address pressing challenges in the earth sciences. Why did you become an Earth scientist? In the mid to late ’70s, the environment became a growing concern. I read all the Golden Guides in the elementary school library to learn about different creatures. I grew up exploring and discovering the surrounding woods, fields, and creeks, both on my own and through scouting and became drawn to nature, its connectedness, and its complexity. The time I spent fishing with my father, a military officer who also worked with meteorology, and my brother helped cement that love. I guess you could say that I became “hooked.” What is your educational background? In 1987, I got a B.A. in environmental science from the University of Virginia. While at UVA, I was a walk-on football player, an offensive lineman on UVA’s first ever post-season bowl team. This furthered my understanding of teamwork, how to work with people who were much more skilled than I was, and how to coach. I received master’s and Ph.D. degrees in environmental science from UVA in 1990 and 1996, respectively. As an undergraduate in environmental sciences, I learned about global biochemical cycling — meaning how carbon and nitrogen move through the living and nonliving systems — while working on research teams in the Chesapeake Bay, the Blue Ridge Mountains and the Amazon Basin. Before graduating I had the good fortune to participate in the NASA Amazon Boundary Layer Experiment (ABLE-2B) in the central Amazon, which I used to kick off my graduate studies. I then focused on southern African aerosol emissions, transports and depositions for my doctoral studies that ultimately led to a university research fellow postdoc at the University of the Witwatersrand in Johannesburg, South Africa. What are some of your career highlights? It has been a crazy journey! While helping put up meteorological towers in the Amazon deep jungle, we would encounter massive squall lines. These storms were so loud as they rained down on the deep forest that you could not hear someone 10 feet away. One of the neatest things that I observed was that after the storms passed, we would see a fine red dust settling on top of our fleet of white Volkswagen rental vehicles in the middle of the rainforest. That observation piqued my interest and led to a paper I wrote about Saharan dust being transported to the Amazon basin and its potential implications for the Amazon, especially regarding nutrient losses from the system. Our initial work suggested there was not enough input from Northern Africa to support the system’s nutrient losses. That caused us to start looking to Sub-Saharan Africa as a potential source of these nutritive species. I finished my master’s during the first Persian Gulf War, and finding a job was challenging. During that phase I diversified my income stream by delivering newspapers and pizzas and also bouncing at a local nightspot so that I could focus on writing papers and proposals related to my research. One of my successes was the winning of a joint National Science Foundation proposal that funded my doctoral research to go to Namibia and examine sources of aerosol and trace gases as part of the larger NASA TRACE-Southern African Atmosphere Fire Research Initiative – 92 (SAFARI-92). We were based at Okaukuejo Rest Camp inside of Namibia’s Etosha National Park for the better part of two months. We characterized conservative chemical tracers of aerosols, their sources and long-range transport from biomass burning regions, which proved, in part, that Central Southern Africa was providing mineral and biomass burning emissions containing biogeochemically important species to far removed, downwind ecosystems thousands of kilometers away. When I returned to Africa as a postdoctoral fellow, I was able to experience other countries and cultures including Lesotho, Mozambique, and Zambia. In 1997, NASA’s AERONET project was also expanding into Africa and I helped Brent Holben and his team deploy instruments throughout Africa in preparation for vicarious validation of instrumentation aboard NASA’s Terra satellite platform. I returned to UVA as a research scientist to work for Chris Justice and his EOS MODIS/Terra validation team. I used this field experience and the international networks I developed, which contributed to my assuming the role of U.S. principal investigator for NASA’s Southern African Regional Science Initiative. Known as SAFARI 2000, it was an effort that involved 250 scientists from 16 different countries and lasted more than three years. When it ended, I became a research professor and began teaching environmental science and mentoring UVA students on international engagement projects. Around 2000, I created a regional knowledge network called Eastern/Southern Africa Virginia Network and Association (ESAVANA) that leveraged the formal and informal structures and networks that SAFARI 2000 established. I used my team building and science diplomacy skills to pull together different regional university partners, who each had unique pieces for unlocking the larger puzzle of how southern Africa acted as a regional coupled human-natural system. Each partner had something important to contribute while the larger potential was only possible by leveraging their respective strengths together as a team. I traveled extensively during this time and was supported in 2001 partially by a Fulbright Senior Specialist Award which allowed me to spend time at the University of Eduardo Mondlane in Maputo Mozambique to help them with hydrology ecosystem issues in the wake of massive floods. We kept the network alive by creating summer study abroad, service learning and intersession January educational programs that drew upon colleagues and their expertise from around the world that attracted new people, energy, and resources to ESAVANA. All of these efforts contributed to a “community of practice” focused on learning about the ethics and protocols of international research. The respectful exchange of committed people and their energies and ideas was key to the effort’s success. I further amplified the impact of this work by contributing my lived and learned experiences to the development of the first ever global development studies major at UVA. In 2004, I had a bad car accident and as a result have battled back and hip issues ever since. After falling off the research funding treadmill, I had to reconfigure myself in the teaching and program consultant sector. I grew more into a teaching role and was recognized for it by UVA’s Z-Society 2008 Professor of the Year, the Carnegie Foundation for the Advancement of Teaching’s Virginia’s 2012 Professor of the Year, as well as my 2014 induction into UVA’s Academy of Teaching — all while technically a research professor. I was also heavily involved for almost a decade with the American Association for the Advancement of Science and its Center for Science Diplomacy and tasks related to activities such as reviewing the Inter-American Institute for Global Change Research and teaching science diplomacy in short courses for the World Academy of Sciences for the Advancement of Science in Developing Countries located in Trieste, Italy, and the Academy of Science of South Africa. I worked in the Earth Sciences Division at NASA Headquarters from 2014 to early 2017 as a rotating program support officer as part of the Intergovernmental Personnel Act (IPA), where I supported the atmospheric composition focus area. One of my responsibilities involved serving as a United States Embassy science fellow in the summer of 2015, where I went to Namibia to support one of our Earth Venture Suborbital field campaigns. I came to Goddard in April 2017 to help revector their nascent global network of ground-based, hyperspectral ultraviolet and visible instruments known as the Pandora. What is your next big project? I am currently working with the NASA Goddard Earth Science Division front office to craft a vision for the next 20 years, which involves the alignment of people around a process to achieve a desired product. With the field of Earth System Science changing so rapidly, we need to position ourselves within this ever evolving “new space” environment of multi-sectoral partners — governmental, commercial, not-for-profit, and academic — from the U.S. and beyond to study the Earth system. This involves working with other governmental agencies, universities and industrial partners to chart a way forward. We will have a lot of new players. We will be working with partners we never imagined. We need people who know how to work across these different sectors. One such attempt to “grow our own timber” involves my development of an experimental version of the first NASA Student Airborne Research Program East Coast Edition (SARP and SARP-East), where student participants from a diversity of institutions of higher learning can see the power and promise of what NASA does, how we work together on big projects, and hopefully be inspired to take on the challenges of the future. In other words, I am pushing an exposure to field-based, Earth system science down earlier into their careers to expose them to what NASA does in an integrated fashion. What assets do you bring to the Earth Science Division front office? In 2020, I came to the Earth science front office to help lead the division. I make myself available across the division to help inspire, collect, suggest, and coach our rank and file into producing really cool mission concept ideas. Part of why the front office wanted me is because I use the skills of relationship building, community building, and science diplomacy to make things happen, to create joint ventures. Having had to support myself for over 20 years on soft money, I learned to become an entrepreneur of sorts — to be scientifically and socially creative — and I was forced to look inward and take an asset-based approach. I look at all the forms of capital I have at hand and use those to make the best of what I have got. In Appalachia, there is an expression: use everything but the squeal from the pig. Lastly, I bring a quick wit with a good dose of self-deprecating humor that helps me connect with people. How do you use science diplomacy to make things happen? Two of the things that bind people together about science are the process of inquiry and utilizing the scientific method, both of which are universally accepted. As such, they allow us to transcend national and cultural divides. Science diplomacy works best when you start with this common foundation. Starting with this premise in collaborative science allows for conversations to take place focusing on what everyone has in common. You can have difficult conversations and respectful confrontations about larger issues. Scientists can then talk and build bridges in unique ways. We did this with SAFARI 2000 while working in a region that had seen two major wars and the system of Apartheid within the previous decade. We worked across borders of people who were previously at odds. We did that by looking at something apart from national identity, which was Southern Africa. We focused on how a large-scale system functions and how to make something that incorporates 10 different countries operate as a unit. We wanted to conduct studies showing how the region operated as a functional unit while dealing with transboundary issues. It took a lot of community and trust, and we began with the science community. What drives you? I want to put knowledge into action to make a difference. I realize it is not about me, it is about “we.” That is why I came to NASA, to make a difference. There is no other agency in the world where we can harness such a unique and capable group of people. What do you do for fun? I enjoy watching sports. I still enjoy hiking, fishing, and tubing down the river. My wife and I like long walks through natural settings with our rescues, Lady, our black-and-tan coonhound, and Duchess, our long-haired German Shepherd Dog. They are our living hot water bottles in the winter. My wife and I also like to cook together. Who would you like to thank? Without a doubt, it starts with my wife, family, and children whom without none of what I have accomplished would have been possible. I have had the good fortune to be able to bring them along on some of my international work, including to Africa. I am also very grateful to all those people during my school years who stepped in and who did not judge me initially by my less than stellar grades. They gave me the chance to become who I am today. Who inspires you? There is an old television show that I really liked called “Connections,” by James Burke. He would start with a topic, go through the history, and show how one action led to another action with unforeseen consequences. He would take something modern like plastics and link it back to Viking times. Extending that affinity for connections, the Resilience Alliance out of Sweden also influences me with their commitment to showing connections and cycles. My mentors at UVA were always open to serving as a sounding board. They treated me as a colleague, not a student, as a member of the guild even though I was still an apprentice. That left an indelible impression upon me and I always try to do the same. My doctoral mentor Mike Garstang said that he already had a job and that this job was to let me stand on his shoulders to allow me to get to the next level, which is my model. Another person who was very formative during my early professional career was Jerry Melillo who showed me what it was like to be an effective programmatic mentor. I worked with him as his chief staffer of an external review of the IAI and learned a lot by watching how he ran that activity program. With respect to NASA, a number of people come to mind: Michael King, Chris Justice, and Tim Suttles, as well as my South African Co-PI, Harold Annegarn, all of whom, at one time or another, took me under their respective wings and mentored me through the whole SAFARI 2000 process. From each of their different perspectives, they taught me how NASA works, how to engage, how to implement a program, and how to navigate office politics. And my sister and our conversations about leadership and what it means to be a servant leader. To be honest, there are scores more individuals who have contributed to my development that I don’t have the space to mention here. What are some of your guiding principles? Never lose the wonder — stay curious. “We” not “me.” Seeking to understand before being understood. We all stand on somebody’s shoulders. Humility rather than hubris. Respect. Be the change you wish to see. By Elizabeth M. Jarrell NASA’s Goddard Space Flight Center, Greenbelt, Md.

Behind her is a 25% scale model of NASA’s SUbsonic Single Aft eNgine (SUSAN) Electrofan aircraft concept used to test and demonstrate hybrid electric propulsion systems for emission reductions and performance boosts in future commercial aircraft. Credit: NASA/Sara Lowthian-Hanna Growing up outside of Philadelphia, Abigail Reigner spent most of her childhood miles away from where her family called home, and where there was little trace of her Native American tribe and culture. Belonging to the Comanche Nation that resides in Lawton, Oklahoma, Reigner’s parents made every effort to keep her connected to her Indigenous heritage and part of a community that would later play a key role in her professional journey. “My parents were really adamant on making sure my brother and I were still involved in the Native American traditions." Abigail Reigner “My parents were really adamant on making sure my brother and I were still involved in the Native American traditions,” Reigner said. “We would go down to Oklahoma often in the summertime, spending time with family and staying immersed in our culture.” Both her parents come from a teaching background, so Reigner was surrounded by hands-on learning experiences early in life. As a school teacher, her mother would participate in local outreach events each year, talking and interacting with students. Her father, a middle school technology education teacher, taught Reigner how to use computer-aided design (CAD) and helped introduce her to the world of engineering at a young age. These unique experiences helped spark Reigner’s curiosity for learning about science, technology, engineering, and math (STEM) and connecting with others in her community who shared these interests. Reigner says she never takes her upbringing for granted. “I feel pretty lucky to have grown up with so many educational opportunities, and I try to use them as a way to give back to my community,” Reigner said. After participating in various engineering and robotics classes in high school and realizing a career in STEM was the right fit for her, Reigner went on to attend the Rochester Institute of Technology in New York where she earned bachelor’s and master’s degrees in mechanical engineering. During her time there, she joined the American Indian Science and Engineering Society (AISES) where she got the unique opportunity to connect with other Indigenous students and mentors in STEM fields and gain leadership experience on projects that eventually set her up for internship opportunities at NASA. “The opportunities I got through AISES led me to get an internship at NASA’s Jet Propulsion Laboratory during the summer of 2021, and then an eight-month co-op the following year working in the center’s materials science division,” Reigner said. Through AISES, Reigner also met Joseph Connolly, an aerospace engineer at NASA’s Glenn Research Center in Cleveland who was looking to recruit Indigenous students for full-time positions in the agency. Upon graduating from college, Reigner joined NASA Glenn as an engineer in the summer of 2024. Abigail Reigner (top far left) and Joseph Connolly (middle far right) pose with NASA employees while staffing a booth at an American Indian Science and Engineering Society (AISES) conference to help recruit Indigenous students to the agency. Credit: Abigail Reigner Today, Reigner works as a systems engineer supporting NASA Glenn’s efforts to test and demonstrate electrified aircraft propulsion technologies for future commercial aircraft as part of the agency’s mission to make air travel more sustainable. One of the projects she works on is NASA’s Electrified Powertrain Flight Demonstration (EPFD), where she supports risk-reduction testing that enables the project to explore the feasibility of hybrid electric propulsion in reducing emissions and improving efficiency in future aircraft. “It’s always good to know that you’re doing something that is furthering the benefit of humanity,” Reigner said. “Seeing that unity across NASA centers and knowing that you are a part of something that is accelerating technology for the future is very cool.” “I really feel like the reason I am here at NASA is because of the success of not just the Native American support group here at Glenn, but also Natives across the agency.” Abigail Reigner The growing community of Native Americans at NASA Glenn has fostered several initiatives over the years that have helped recruit, inspire, and retain Indigenous employees. Leveraging some of the agency’s diversity programs that provide educational STEM opportunities for underrepresented communities, the Native Americans at NASA group has encouraged more students with Indigenous backgrounds to get involved in technical projects while developing the skills needed to excel in STEM fields. “The Native American support group at NASA has been around since the mid-to-late 1980s and was actually one of the first Native American employee resources groups at the agency,” Connolly said. “Through this, we’ve been able to connect a number of Native employees with senior leaders across NASA and establish more agencywide recruitment efforts and initiatives for Native Americans.” These initiatives range from support through NASA’s Minority University Research and Education Project (MUREP) to help recruit more Indigenous students, to encouraging participation in hands-on learning experiences through projects such as NASA’s University Leadership Initiative (ULI) and the agency’s involvement in the First Nations Launch competition, which helps provide students with opportunities to conduct research while developing engineering and team-building skills. The efforts of the Native American community at NASA Glenn and across the agency have been successful in not only creating a direct pipeline for Indigenous students into the NASA workforce, but also allowing them to feel seen and represented in the agency, says Connolly. For Reigner, having this community and resource group at NASA to help guide and support her through her journey has been crucial to her success and important for the future of diversity within the agency. “I really feel like the reason I am here at NASA is because of the success of not just the Native American support group here at Glenn, but also Natives across the agency,” Reigner said. Without their support and initiatives to recruit and retain students, I wouldn’t be here today.” Explore More 7 min read Six Ways Supercomputing Advances Our Understanding of the Universe Article 4 days ago 1 min read NASA Glenn Chief Counsel Named to CSU Law Hall of Fame Article 6 days ago 1 min read NASA Encourages Careers in STEM During Event Article 6 days ago View the full article

NASA/JPL-Caltech Earth planning date: Friday, Nov. 15, 2024 The Monday plan and drive had executed successfully, so the team had high hopes for APXS and MAHLI data on several enticing targets in the rover’s workspace. Alas, it was not to be: The challenging terrain had resulted in an awkwardly perched wheel at the end of the drive, so we couldn’t risk deploying the arm from this position. Maybe next drive! We did plan a busy weekend of non-arm science activities regardless. Due to a “soliday” the weekend has two sols instead of three, but we had enough power available to fit in more than three hours of observations. The two LIBS observations in the plan will measure the composition of the flat, reddish material in the workspace that is fractured in a polygonal pattern (“Bloody Canyon”) and a nearby rock coating in which the composition is suspected to change with depth (“Burnt Camp Creek”). One idea is that the reddish material could be the early stage version of the thicker dark coatings we’ve been seeing. A large Mastcam mosaic (“Yosemite”) was planned to capture the very interesting view to the rover’s north. Nearby and below the rover is the layer of rocks in which the “Mineral King” site was drilled on the opposite side of the channel back in March. This is a stratum of sulfate-bearing rock that appears dark-toned from orbit and we’re interested to know how consistent its features are from one side of the channel to the other. Higher up, the Yosemite mosaic also captures some deformation features that may reveal past water activity, and some terrain associated with the Gediz Vallis ridge. So there’s a lot of science packed into one mosaic! Two long-distance RMI mosaics were planned; one is to image back into the channel, where there may be evidence of a late-stage debris flow at the base of the ridge. The second looks “forward” from the rover’s perspective instead, into the wind-shaped yardang unit above us that will hopefully be explored close-up in the rover’s future. This yardang mosaic is intended to form one part of a stereo observation. The modern environment on Mars will also be observed with dust devil surveys on both sols, line-of-sight and tau observations to measure atmospheric opacity (often increased by dust in the atmosphere), and zenith and suprahorizon movies with Navcam to look for clouds. There will also be standard passive observations of the rover’s environment by REMS and DAN. We’ll continue driving westward and upward, rounding the Texoli butte to keep climbing through the sulfate-bearing unit. It’s not always easy driving but there’s a lot more science to do!

  17. Linda Spuler, emergency manager at NASA’s Johnson Space Center in Houston, believes that everyone has a story. “Our stories highlight what we have in common, but they also make us each unique,” she said. Spuler has worked at Johnson for over 32 years, spending most of her career in Center Operations. Her story has involved helping to coordinate emergency response teams at Johnson in preparation for natural disasters. “Since Johnson is situated on the coast, a good portion of my job revolves around planning for hurricanes,” she said. Spuler has dealt with natural disasters at Johnson from Tropical Storm Allison in 2001 to Hurricane Beryl in 2024, but none had a greater personal impact than Hurricane Ike, which wrought havoc in Texas in September 2008. “Participating in the response to Hurricane Ike was a proud moment for me,” she said. “We worked from sunup to sundown restoring the center. Civil servants and contractors from various organizations came together, and for those two weeks, our differences didn’t matter.” NASA’s Johnson Space Center Emergency Manager Linda Spuler, front, leads an emergency exercise for first responders. Image courtesy of Linda Spuler Spuler believes that NASA’s mission unites everyone – team members, astronauts, and support teams alike. “Remembering why we are all here energizes us and gets us excited about working for NASA,” she said. Spuler’s journey at NASA began as a dream not originally her own. Her path was shaped by the aspirations of her mother, who was born on an Ojibwe (Chippewa) reservation in Ashland, Wisconsin. “Although my grandmother lived in Chicago, she returned to the reservation to have her children. My mom is still a voting member of the Bad River Tribe,” said Spuler. “My mom was studying aerospace engineering at the University of Chicago when she met my dad, a fun-loving electrical engineering major who traced his lineage back to Davy Crockett on his father’s side and Ireland on his mother’s,” said Spuler. “She chose to abandon aerospace to marry my dad, whose degree and love for space brought him to work at Johnson.” Linda Spuler accepts the Thirty-Year Service Award from Johnson Director Vanessa Wyche to commemorate her service at NASA. NASA/David DeHoyos Spuler said her mother was very proud that her father worked for NASA. “She was very happy when I chose to work here, too,” she said. “She taught me the value and reward of working hard. My mom is proud of her heritage but she is cautious of sharing her story.” Linda Spuler at an Easter egg hunt at NASA’s Johnson Space Center in 1971. Image courtesy of Linda Spuler Spuler enjoys learning about Ojibwe culture from her mother. “Every Thanksgiving, we enjoy wild rice from the Bad River sent from the “aunties” that still live on the reservation,” Spuler shared. She also represents her culture and pride through her work, honoring the legacy of those who came before her and sharing the story of her mother, her father, and now herself. Linda Spuler receives the 2019 Furlough Heroes Awards alongside her son, Logan.

  19. Anthocyanins protect seeds in space After exposure to space outside the International Space Station, purple-pigmented rice seeds rich in anthocyanin had higher germination rates than non-pigmented white rice seeds. This result suggests that anthocyanin, a flavonoid known to protect plants from UV irradiation, could help preserve seed viability on future space missions. Plants are key components for systems being designed to produce nutrients and recycle carbon for future sustained space habitation, but space has been shown to reduce seed viability. Tanpopo-3, part of a series of investigations from JAXA (Japan Aerospace Exploration Agency), examined the role of anthocyanins in maintaining seed viability. Results of this and previous experiments suggest that solar light in space is more detrimental to seeds than radiation. Preflight image of the Tanpopo panel used to expose seeds and other samples to space.

United Arab Emirates/Sultan Alneyadi Insights from observations of an X-ray binary star Researchers used Neutron star Interior Composition Explorer (NICER) to observe the timing of 15 X-ray bursts from 4U 1820–30, an ultracompact X-ray binary (UCXB) star. An X-ray binary is a neutron star orbiting a companion from which it takes matter. If confirmed with future observations, this result makes 4U 1820–30 the fastest-spinning neutron star known in an X-ray binary system and provides insights into the physics of neutron stars. NICER makes high-precision measurements of neutron stars (the ultra-dense matter created when massive stars explode as supernovas) and other phenomena to increase our understanding of the universe. NICER has monitored 4U 1820–30 since its launch in June 2017. A short orbital period indicates a relatively small binary system, and 4U 1820–30 has the shortest known orbital period among low-mass X-ray binaries.

  20. When Ariel Vargas joined NASA in 2023, he knew he wanted to make an impact. Despite his relatively short tenure, he has earned the reputation of a Digital Transformer in his work as a Network and ICAM (Identity, Credential, and Access Management) Service Integrator at Johnson Space Center (JSC). No matter the task at hand, Ariel is motivated by measurable transformation. “I wanted to have my fingerprint on something no matter what it was, big or small. To be able to see an impact,” he says. “And a lot of the things that I’m doing, both within my role and within Digital Transformation, I can see really flourishing already.” In his current role, Ariel oversees the integration and management of various network services to ensure compliance and smooth operation. This includes the modernization of NASA’s Voice over Internet Protocol (VoIP) to consolidate the agency’s telephone systems and enhance wireless communications. He is involved in rolling out wall-to-wall wireless and coverage improvements on campus at JSC. Ariel also spearheads efforts in streamlining communications across NASA by integrating new capabilities into familiar platforms like Microsoft Teams. With these projects in progress, he aims to foster a more flexible, collaborative work environment aligned with Digital Transformation’s goal of inclusive teaming. Ariel appreciates the cultural side of Digital Transformation, particularly the challenges involved in pursuing constant innovation. He recognizes that growth “often requires a period of adjustment, especially for those encountering new tools or methods for the first time.” Ariel strives to ensure cohesive collaboration across teams and centers in establishing interoperable architectures, processes, and tools. His team measures the impact of their transformation efforts by several metrics, including increased network performance and adoption rates of new tools and technologies. For instance, the VoIP modernization initiative aims to remove 50% of telephones at NASA centers. Of the over 1300 users affected by the NASA-wide service shut-off of non-compliant phones at JSC, only 6% reported issues post-implementation. This reflected a positive and proactive collaboration with users on finding alternative solutions and embracing future innovations. I really believe in embracing changes and innovation and driving impactful results, being able to see it. Ariel Vargas Network and ICAM (Identity, Credential, and Access Management) Service Integrator at Johnson Space Center (JSC) Lynn Vernon, JSC’s Digital Transformation lead and Chief Engineer for IT, notes Ariel’s ability to engage with partners, understand their mission needs, and identify innovative solutions to barriers. “Ariel looks at things from a new perspective and is willing to ask ‘why’ or ‘why not.’ Why do we do it this way? Why not try this? He is consistently willing to explore new technologies and capabilities to transform the way we work,” says Lynn. Ariel’s passion for continuous improvement and learning positions him as a natural leader within the Digital Transformation community. Ariel took a unique path to NASA and sees his prior experiences as building blocks toward becoming the Digital Transformer he is today. Although his upbringing in Florida near Cape Canaveral sparked an early interest in space, Ariel initially pursued pre-medicine after high school before transitioning into the Army. After his service, he joined NASA as an intern through the Department of Defense’s SkillBridge program, which offers career assistance to transitioning military personnel. His ability to learn NASA’s culture and demonstrate mission value quickly led to a full-time, civil servant position. Between his initial interest in medicine, his service in the Army, and his current focus on digital transformation and technology, Ariel sees a common theme of problem-solving. “You have to figure out what the problem is, and you have to be up to date with the newest, the latest and greatest, to help solve these problems.” Ariel followed this thread to complete a master’s degree in computer science and is currently pursuing a doctorate in instructional design and performance technology. Even outside his work at NASA, Ariel pursues pathways that further his capacity as a champion of Digital Transformation initiatives. Looking to the future, Ariel is excited by the possibility of supporting NASA’s space missions through AI and data integration. He is motivated by the prospect of seeing his current work make a difference in the near-term future. “I really believe in embracing changes and innovation and driving impactful results, being able to see it,” he says. Given his accomplishments of the past year, Ariel is well on his way to realizing the future he envisions. View the full article

  22. On Nov. 16, 2009, space shuttle Atlantis began its 31st trip into space, on the third Utilization and Logistics Flight (ULF3) mission to the International Space Station, the 31st shuttle flight to the orbiting lab. During the 11-day mission, the six-member STS-129 crew worked with the six-person Expedition 21 crew during seven days of docked operations. The mission’s primary objectives included delivering two external logistics carriers and their spare parts, adding nearly 15 tons of hardware to the station, and returning a long-duration crew member, the last to return on a shuttle. Three of the STS-129 astronauts conducted three spacewalks to transfer spare parts and continue assembly and maintenance of the station. As a group of 12, the joint crews celebrated the largest and most diverse Thanksgiving gathering in space. Left: Official photograph of the STS-129 crew of Leland D. Melvin, left, Charles O. Hobaugh, Michael J. Foreman, Robert “Bobby” L. Satcher, Barry “Butch” E. Wilmore, and Randolph “Randy” J. Bresnik. Middle: The STS-129 crew patch. Right: The ULF3 payload patch. The six-person STS-129 crew consisted of Commander Charles O. Hobaugh, Pilot Barry “Butch” E. Wilmore, and Mission Specialists Randolph “Randy” J. Bresnik, Michael J. Foreman, Leland D. Melvin, and Robert “Bobby” L. Satcher. Primary objectives of the mission included launch and transfer to the station of the first two EXPRESS Logistics Carriers (ELC-1 and ELC-2) and their multiple spare parts, and the return of NASA astronaut and Expedition 20 and 21 Flight Engineer Nicole P. Stott, the last astronaut to rotate on the shuttle. Left: In the Orbiter Processing Facility (OPF) at NASA’s Kennedy Space Center in Florida, workers finish processing Atlantis for STS-129.

Right: The STS-129 crew during the Terminal Countdown Demonstration Test. Atlantis returned to NASA’s Kennedy Space Center (KSC) from its previous mission, STS-125, on June 2, 2009, and workers towed it to the Orbiter Processing Facility (OPF) to prepare it for STS-129. The orbiter rolled over to the Vehicle Assembly Building on Oct. 6, and after mating with its external tank and twin solid rocket boosters, rolled out to Launch Pad 39A on Oct. 14, targeting a Nov. 16 launch. Six days later, the six-member crew participated in the Terminal Countdown Demonstration Test, essentially a dress rehearsal of the actual countdown for launch, returning to Houston for final training. They returned to KSC on Nov. 13 to prepare for launch. Left: With Atlantis sitting on Launch Pad 39A, the Ares 1-X rocket lifts off from Launch Pad 39B.

On Nov. 16, at 2:28 p.m. EST, space shuttle Atlantis lifted off from Launch Pad 39A to begin its 31st trip into space, carrying its six-member crew on the ULF3 space station outfitting and resupply mission. Eight and a half minutes later, Atlantis and its crew had reached orbit. The flight marked Hobaugh’s third time in space, having flown on STS-104 and STS-118, Foreman’s and Melvin’s second, having flown on STS-123 and STS-122, respectively, while Wilmore, Bresnik, and Satcher enjoyed their first taste of weightlessness. Left: The two EXPRESS Logistics Carriers in Atlantis’ payload bay. Middle: Leland D. Melvin participates in the inspection of Atlantis’ thermal protection system. Right: The Shuttle Remote Manipulator System grasps the Orbiter Boom Sensor System for the inspection. After reaching orbit, the crew opened the payload bay doors, deployed the shuttle’s radiators, and removed their bulky launch and entry suits, stowing them for the remainder of the flight. The astronauts spent six hours on their second day in space conducting a detailed inspection of Atlantis’ nose cap and wing leading edges, with Hobaugh, Wilmore, Melvin, and Bresnik taking turns operating the Shuttle Remote Manipulator System (SRMS), or robotic arm, and the Orbiter Boom Sensor System (OBSS).

Middle: Atlantis as seen from the space station, showing the two EXPRESS Logistics Carriers (ELC) in the payload bay. Right: View of the space station from Atlantis during the rendezvous pitch maneuver, with the Shuttle Remote Manipulator System grasping ELC-1 in preparation for transfer shortly after docking. On the mission’s third day, Hobaugh assisted by his crewmates brought Atlantis in for a docking with the space station. During the rendezvous, Hobaugh stopped the approach at 600 feet and completed the Rendezvous Pitch Maneuver so astronauts aboard the station could photograph Atlantis’ underside to look for any damage to the tiles. Shortly after docking, the crews opened the hatches between the two spacecraft and the six-person station crew welcomed the six-member shuttle crew. After the welcoming ceremony, Stott joined the STS-129 crew, leaving a crew of five aboard the station. Melvin and Bresnik used the SRMS to pick up ELC-1 from the payload bay and hand it off to Wilmore and Expedition 21 NASA astronaut Jeffrey N. Williams operating the Space Station Remote Manipulator System (SSRMS), who then installed it on the P3 truss segment. Images from the first spacewalk. Left: Michael J.

Right: Satcher’s image reflected in a Z1 radiator panel. During the mission’s first of three spacewalks on flight day four, Foreman and Satcher ventured outside for six hours and 37 minutes. During the excursion, with robotic help from their fellow crew members, they transferred a spare S-band Antenna Support Assembly from the shuttle’s payload bay to the station’s Z1 truss. Satcher, an orthopedic surgeon by training, performed “surgery” on the station’s main robotic arm as well as the robotic arm on the Kibo Japanese module, by lubricating their latching end effectors. One day after joining Atlantis’ crew, Stott celebrated her 47th birthday. Left: Space station crew member Jeffery N. Williams assists STS-129 astronaut Leland D.

Right: Michael J. Foreman, left, and Randolph J. Bresnik during the mission’s second spacewalk. On the mission’s fifth day, the astronauts performed another focused inspection of the shuttle’s thermal protection system. The next day, through another coordinated robotic activity involving the shuttle and station arms, the astronauts transferred ELC-2 and its complement of spares from the payload bay to the station’s S3 truss. Foreman and Bresnik completed the mission’s second spacewalk. Working on the Columbus module, they installed the Grappling Adaptor to On-Orbit Railing (GATOR) fixture that includes a system used for ship identification and an antenna for Ham radio operators. They next installed a wireless video transmission system on the station’s truss. This spacewalk lasted six hours and eight minutes. Left: Randolph J. Bresnik during the third STS-129 spacewalk.

Following a crew off duty day, on flight day eight Satcher and Bresnik exited the airlock for the mission’s third and final spacewalk. Their first task involved moving an oxygen tank from the newly installed ELC-2 to the Quest airlock. They accomplished this task with robotic assistance from their fellow crew members. Bresnik retrieved the two-suitcase sized MISSE-7 experiment containers from the shuttle cargo bay and installed them on the MISSE-7 platform on ELC-2, opening them to begin their exposure time. This third spacewalk lasted five hours 42 minutes. Left: An early Thanksgiving meal for 12 aboard the space station. Right: After the meal, who has the dishes? Thanksgiving Day fell on the day after undocking, so the joint crews celebrated with a meal a few days early. The meal represented not only the largest Thanksgiving celebration in space with 12 participants, but also the most international, with four nations represented – the United States, Russia, Canada, and Belgium (representing the European Space Agency).

Left: The space station seen from Atlantis during the flyaround. Middle: Atlantis as seen from the space station during the flyaround, with a now empty payload bay. Right: Astronaut Nicole P. Stott looks back at the station, her home for three months, from the departing Atlantis. On flight day nine, the joint crews held a brief farewell ceremony. European Space Agency astronaut Frank De Winne, the first European to command the space station, handed over command to NASA astronaut Williams. The two crews parted company and closed the hatches between the two spacecraft. The next day, with Wilmore at the controls, Atlantis undocked from the space station, having spent seven days as a single spacecraft. Wilmore completed a flyaround of the station, with the astronauts photographing it to document its condition. A final separation burn sent Atlantis on its way. The astronauts used the shuttle’s arm to pick up the OBSS and perform a late inspection of Atlantis’ thermal protection system. On flight day 11, Hobaugh and Wilmore tested the orbiter’s reaction control system thrusters and flight control surfaces in preparation for the next day’s entry and landing. The entire crew busied themselves with stowing all unneeded equipment. Left: Atlantis about to touch down at NASA’s Kennedy Space Center in Florida. Middle: Atlantis touches down.

Right: The welcome home ceremony for the STS-129 crew at Ellington Field in Houston. On Nov. 27, the astronauts closed Atlantis’ payload bay doors, donned their launch and entry suits, and strapped themselves into their seats, a special recumbent one for Stott who had spent the last three months in weightlessness. Hobaugh fired Atlantis’ two Orbital Maneuvering System engines to bring them out of orbit and head for a landing half an orbit later. He guided Atlantis to a smooth touchdown at KSC’s Shuttle Landing Facility. The landing capped off a very successful STS-129 mission of 10 days, 19 hours, 16 minutes. The six astronauts orbited the planet 171 times. Stott spent 90 days, 10 hours, 45 minutes in space, completing 1,423 orbits of the Earth. After towing Atlantis to the OPF, engineers began preparing it for its next flight, STS-132 in May 2010. The astronauts returned to Houston for a welcoming ceremony at Ellington Field.

  23. 5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Use your mouse to explore this 360-degree view of Gediz Vallis channel, a region of Mars that NASA’s Curiosity rover surveyed before heading west to new adventures. NASA/JPL-Caltech/MSSS The rover captured a 360-degree panorama before leaving Gediz Vallis channel, a feature it’s been exploring for the past year. NASA’s Curiosity rover is preparing for the next leg of its journey, a monthslong trek to a formation called the boxwork, a set of weblike patterns on Mars’ surface that stretches for miles. It will soon leave behind Gediz Vallis channel, an area wrapped in mystery. How the channel formed so late during a transition to a drier climate is one big question for the science team. Another mystery is the field of white sulfur stones the rover discovered over the summer. Curiosity imaged the stones, along with features from inside the channel, in a 360-degree panorama before driving up to the western edge of the channel at the end of September. The rover is searching for evidence that ancient Mars had the right ingredients to support microbial life, if any formed billions of years ago, when the Red Planet held lakes and rivers. Located in the foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain, Gediz Vallis channel may help tell a related story: what the area was like as water was disappearing on Mars. Although older layers on the mountain had already formed in a dry climate, the channel suggests that water occasionally coursed through the area as the climate was changing. Scientists are still piecing together the processes that formed various features within the channel, including the debris mound nicknamed “Pinnacle Ridge,” visible in the new 360-degree panorama. It appears that rivers, wet debris flows, and dry avalanches all left their mark. The science team is now constructing a timeline of events from Curiosity’s observations. NASA’s Curiosity captured this panorama using its Mastcam while heading west away from Gediz Vallis channel on Nov. 2, 2024, the 4,352nd Martian day, or sol, of the mission. The Mars rover’s tracks across the rocky terrain are visible at right.NASA/JPL-Caltech/MSSS The science team is also trying to answer some big questions about the sprawling field of sulfur stones. Images of the area from NASA’s Mars Reconnaissance Orbiter (MRO) showed what looked like an unremarkable patch of light-colored terrain. It turns out that the sulfur stones were too small for MRO’s High-Resolution Imaging Science Experiment (HiRISE) to see, and Curiosity’s team was intrigued to find them when the rover reached the patch. They were even more surprised after Curiosity rolled over one of the stones, crushing it to reveal yellow crystals inside. Science instruments on the rover confirmed the stone was pure sulfur — something no mission has seen before on Mars. The team doesn’t have a ready explanation for why the sulfur formed there; on Earth, it’s associated with volcanoes and hot springs, and no evidence exists on Mount Sharp pointing to either of those causes. “We looked at the sulfur field from every angle — from the top and the side — and looked for anything mixed with the sulfur that might give us clues as to how it formed. We’ve gathered a ton of data, and now we have a fun puzzle to solve,” said Curiosity’s project scientist Ashwin Vasavada at NASA’s Jet Propulsion Laboratory in Southern California. NASA’s Curiosity Mars rover captured this last look at a field of bright white sulfur stones on Oct. 11, before leaving Gediz Vallis channel. The field was where the rover made the first discovery of pure sulfur on Mars. Scientists are still unsure exactly why theses rocks formed here. Spiderwebs on Mars Curiosity, which has traveled about 20 miles (33 kilometers) since landing in 2012, is now driving along the western edge of Gediz Vallis channel, gathering a few more panoramas to document the region before making tracks to the boxwork. Viewed by MRO, the boxwork looks like spiderwebs stretching across the surface. It’s believed to have formed when minerals carried by Mount Sharp’s last pulses of water settled into fractures in surface rock and then hardened. As portions of the rock eroded away, what remained were the minerals that had cemented themselves in the fractures, leaving the weblike boxwork. On Earth, boxwork formations have been seen on cliffsides and in caves. But Mount Sharp’s boxwork structures stand apart from those both because they formed as water was disappearing from Mars and because they’re so extensive, spanning an area of 6 to 12 miles (10 to 20 kilometers). Scientists think that ancient groundwater formed this weblike pattern of ridges, called boxwork, that were captured by NASA’s Mars Reconnaissance Orbiter on Dec. 10, 2006. The agency’s Curiosity rover will study ridges similar to these up close in 2025.NASA/JPL-Caltech/University of Arizona This weblike crystalline structure called boxwork is found in the ceiling of the Elk’s Room, part of Wind Cave National Park in South Dakota. NASA’s Curiosity rover is preparing for a journey to a boxwork formation that stretches for miles on Mars’ surface. “These ridges will include minerals that crystallized underground, where it would have been warmer, with salty liquid water flowing through,” said Kirsten Siebach of Rice University in Houston, a Curiosity scientist studying the region. “Early Earth microbes could have survived in a similar environment. That makes this an exciting place to explore.” More About Curiosity Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California.
