ESA/Hubble & NASA, M. J. Koss, A. J. Barth The light that the NASA/ESA Hubble Space Telescope collected to create this image reached the telescope after a journey of 250 million years. Its source was the spiral galaxy UGC 11397, which resides in the constellation Lyra (The Lyre). At first glance, UGC 11397 appears to be an average spiral galaxy: it sports two graceful spiral arms that are illuminated by stars and defined by dark, clumpy clouds of dust. What sets UGC 11397 apart from a typical spiral lies at its center, where a supermassive black hole containing 174 million times the mass of our Sun grows. As a black hole ensnares gas, dust, and even entire stars from its vicinity, this doomed matter heats up and puts on a fantastic cosmic light show. Material trapped by the black hole emits light from gamma rays to radio waves, and can brighten and fade without warning. But in some galaxies, including UGC 11397, thick clouds of dust hide much of this energetic activity from view in optical light. Despite this, UGC 11397’s actively growing black hole was revealed through its bright X-ray emission — high-energy light that can pierce the surrounding dust. This led astronomers to classify it as a Type 2 Seyfert galaxy, a category used for active galaxies whose central regions are hidden from view in visible light by a donut-shaped cloud of dust and gas. Using Hubble, researchers will study hundreds of galaxies that, like UGC 11397, harbor a supermassive black hole that is gaining mass. The Hubble observations will help researchers weigh nearby supermassive black holes, understand how black holes grew early in the universe’s history, and even study how stars form in the extreme environment found at the very center of a galaxy.

Lisa Pace knows a marathon when she sees one. An avid runner, she has participated in five marathons and more than 50 half marathons. Though she prefers to move quickly, she also knows the value of taking her time. “I solve most of my problems while running – or realize those problems aren’t worth worrying about,” she said. She has learned to take a similar approach to her work at NASA’s Johnson Space Center in Houston. “Earlier in my career, I raced to get things done and felt the need to do as much as possible on my own,” she said. “Over time, I’ve learned to trust my team and pause to give others an opportunity to contribute. There are times when quick action is needed, but it is often a marathon, not a sprint.” Official portrait of Lisa Pace.NASA/Josh Valcarcel Pace is chief of the Exploration Development Integration Division within the Exploration Architecture, Integration, and Science Directorate at Johnson. In that role, she leads a team of roughly 120 civil servants and contractors in providing mission-level system engineering and integration services that bring different architecture elements together to achieve the agency’s goals. Today that team supports Artemis missions, NASA’s Commercial Lunar Payload Services initiative and other areas as needed. Lisa Pace, seated at the head of the table, leads an Exploration Development Integration Division team meeting at NASA’s Johnson Space Center in Houston. NASA/James Blair “The Artemis missions come together through multiple programs and projects,” Pace explained. “We stitch them together to ensure the end-to-end mission meets its intended requirements. That includes verifying those requirements before flight and ensuring agreements between programs are honored and conflicts resolved.” The division also manages mission-level review and flight readiness processes from planning through execution, up to the final certification of flight readiness. Leading the division through the planning, launch, and landing of Artemis I was a career highlight for Pace, though she feels fortunate to have worked on many great projects during her time with NASA. “My coolest and most rewarding project involved designing and deploying an orbital debris tracking telescope on Ascension Island about 10 years ago,” she said. “The engineers, scientists, and military personnel I got to work and travel with on that beautiful island is tough to top!” Pace says luck and great timing led her to NASA. Engineering jobs were plentiful when she graduated from Virginia Tech in 2000, and she quickly received an offer from Lockheed Martin to become a facility engineer in Johnson’s Astromaterials Research and Exploration Science Division, or ARES. “I thought working in the building where they keep the Moon rocks would be cool – and it was! Twenty-five years later, I’m still here,” Pace said. During that time, she has learned a lot about problem-solving and team building. “I often find that when we disagree over the ‘right’ way to do something, there is no one right answer – it just depends on your perspective,” she said. “I take the time to listen to people, understand their side, and build relationships to find common ground.” Lisa Pace, right, participates in a holiday competition hosted by her division.Image courtesy of Lisa Pace She also emphasizes the importance of getting to know your colleagues. “Relationships are everything,” she said. “They make the work so much more meaningful. I carry that lesson over to my personal life and value my time with family and friends outside of work.” Investing time in relationships has given Pace another unexpected skill – that of matchmaker. “I’m responsible for setting up five couples who are now married, and have six kids between them,” she said, adding that she knew one couple from Johnson. She hopes that strong relationships transfer to the Artemis Generation. “I hope to pass on a strong NASA brand and the family culture that I’ve been fortunate to have, working here for the last 25 years.” Explore More 3 min read Meet Rob Navias: Public Affairs Officer and Mission Commentator Article 5 days ago 5 min read Heather Cowardin Safeguards the Future of Space Exploration Article 1 week ago 5 min read Driven by a Dream: Farah Al Fulfulee’s Quest to Reach the Stars Article 2 weeks ago View the full article

2 Min Read NASA Announces Winners of 2025 Human Lander Challenge NASA’s Human Lander Challenge marked its second year on June 26, awarding $18,000 in prize money to three university teams for their solutions for long-duration cryogenic, or super chilled, liquid storage and transfer systems for spaceflight. Building on the crewed Artemis II flight test, NASA’s Artemis III mission will send astronauts to explore the lunar South Pole region with a human landing system and advanced spacesuits, preparing humanity to ultimately go to Mars. In-space propulsion systems that use cryogenic liquids as propellants must stay extremely cold to remain in a liquid state and are critical to mission success. The Artemis mission architecture will need these systems to function for several weeks or even months. Students and advisors with the 12 finalist teams for the 2025 Human Lander Challenge competed in Huntsville, Alabama, near the agency’s Marshall Space Flight Center between June 24-26. NASA/Charles Beason NASA announced Embry-Riddle Aeronautical University, Prescott as the overall winner and recipient of the $10,000 top prize award. Old Dominion University won second place and a $5,000 award, followed by Massachusetts Institute of Technology in third place and a $3,000 award. Before the winners were announced, 12 finalist teams selected in April gave their presentations to a panel of NASA and industry judges as part of the final competition in Huntsville. As part of the 2025 Human Lander Challenge, university teams developed systems-level solutions that could be used within the next 3-5 years for Artemis. NASA selected Embry-Riddle Aeronautical University, Prescott as the overall winner of NASA’s 2025 Human Lander Challenge Forum June 26. Lisa Watson-Morgan, manager of NASA’s Human Landing System Program, presented the awards at the ceremony. NASA/Charles Beason “Today’s Golden Age of Innovation and Exploration students are tomorrow’s mission designers, systems engineers, and explorers,” said Juan Valenzuela, main propulsion systems and cryogenic fluid management subsystems lead for NASA’s Human Landing System Program at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The Human Lander Challenge concepts at this year’s forum demonstrate the ingenuity, passion, and determination NASA and industry need to help solve long-duration cryogenic storage challenges to advance human exploration to deep space.” The challenge is sponsored by the agency’s Human Landing System Program within the Exploration Systems Development Mission Directorate and managed by the National Institute of Aerospace. Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

In 1963, Captain Engle was assigned as one of two Air Force test pilots to fly the X-15 Research Rocket aircraft. In 1965, he flew the X-15 to an altitude of 280,600 feet, and became the youngest pilot ever to qualify as an astronaut. Three of his sixteen flights in the X-15 exceeded the 50-mile (264,000 feet) altitude required for astronaut rating.NASA Former NASA astronaut Joe Engle poses in front of an X-15 plane in this Dec. 2, 1965, photo. On June 29, 1965, Engle flew the X-15 to 280,600 feet, becoming the youngest U.S. pilot to qualify as an astronaut. The Kansas native flew the X-15 for the U.S. Air Force 16 times from 1963 to 1965. Three times Engle flew an X-15 higher than 50 miles (the altitude required for astronaut rating), officially qualifying him for Air Force astronaut wings and providing him a brief moment for sightseeing at the edge of space. “You could glance out and see the blackness of space above and the extremely bright Earth below. The horizon had the same bands of color you see from the shuttle, with black on top, then purple to deep indigo, then blues and whites,” he said. Image credit: NASA View the full article

Astrophysics Science Video Producer – Goddard Space Flight Center Growing up in Detroit with a camera in her hand, Sophia Roberts — now an award-winning astrophysics science video producer—never imagined that one day her path would wind through clean rooms, vacuum chambers, and even a beryllium mine. But framing the final frontier sometimes requires traveling through some of Earth’s less-explored corners. Sophia Roberts is an astrophysics Science video producer at NASA’s Goddard Space Flight Center in Greenbelt, Md. She films space hardware assembly and explains complicated topics, weaving science and art together.Credit: Courtesy of Sophia Roberts Sophia received her first camera from her father, a photography enthusiast, when she was just five or six years old. “I’ve basically been snapping away ever since!” she says. With a natural curiosity and enthusiasm for science, Sophia pursued a degree in biology at Oberlin College in Ohio. There, she discovered that she could blend her two passions. “I often lingered in lab sessions, not to finish an experiment but to photograph it,” Sophia says. “I had an epiphany at the beginning of class one day, which always opened with clips from BBC nature documentaries. I decided right then that I would be one of the people who make those videos one day.” Part of Sophia’s role currently involves documenting NASA’s Nancy Grace Roman Space Telescope, which is taking shape and being tested at NASA Goddard. She captured a cosmic selfie while photographing the telescope’s primary mirror, which was designed and built by L3Harris Technologies in Rochester, New York, before it was integrated with other components.Credit: NASA/Sophia Roberts She initially thought that meant wildlife filmmaking—perched in a blind on a mountainside, waiting hours for an animal to appear. That dream led her to Montana State University, where she learned to blend scientific rigor with visual storytelling through their science and natural history filmmaking master’s program. While completing her degree, Sophia worked as a traveling presenter for the Montana Space Grant Consortium. “I was mainly giving presentations about NASA missions and showing kids beautiful images of space,” she says. “That was my first true introduction to NASA. I loved being able to watch the children’s eyes light up when they saw what’s out there in space.” Sophia then completed an internship at the Smithsonian’s National Museum of Natural History while completing her thesis. Once she graduated, she landed a year-long fellowship at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as an Earth science news fellow. In this role, she focused on packaging up stories through satellite imagery and explanations. Sophia holds a Webby award she, Mike McClare (left), and Michael Starobin (right) won for their broadcasts of the James Webb Space Telescope’s launch, deployment, and first images.Credit: James Hartley She leaned into her videography skills in her next role, as part of NASA’s James Webb Space Telescope team. “Webb is one of my great loves in life,” she says. “I learned to negotiate with engineers for the perfect shot, navigate NASA’s protocols, and work with mission partners. I only spent five years on Webb, but it feels like it was half my life. Still—it was everything.” That mission took her to some unforgettable places, like a mine in Delta, Utah, where raw material for Webb’s mirrors was unearthed. “It was this giant, spiral pit where they were mining beryllium at just 0.02% concentration,” Sophia says. The process was as otherworldly as the location. In 2021, Sophia traveled to Delta, Utah to capture behind-the-scenes footage of raw material for the James Webb Space Telescope’s mirrors being unearthed. In this gif, a drone captures an aerial view of the site.Credit: Scott Rogers She also documented thermal vacuum testing at NASA’s Johnson Space Center in Houston in a giant pill-shaped chamber with a 40-foot round door. “I had to take confined space training to crawl around in the area underneath the chamber,” she says. “It felt like spelunking.” Once Webb launched, Sophia pivoted to covering many of NASA’s smaller astrophysics missions along with the upcoming Nancy Grace Roman Space Telescope. These days, she can often be found gowned up in a “bunny suit” in the largest clean room at Goddard to document space telescope assembly, or in a studio recording science explanations. Sophia stands in the largest clean room at Goddard, where she documents space hardware coming together. Credit: NASA/Chris Gunn “I love capturing the visual stories and helping fill in the gaps to help people understand NASA research,” Sophia says. “I try to focus on the things that will get people excited about the science so they’ll stop scrolling to find out more.” For Sophia, the process is often as exhilarating as the result. “I love venturing out to remote places where science is being done,” she says. “I’d love to film a balloon launch in Antarctica someday!” Jacob Pinter (left), host of NASA’s Curious Universe Podcast, leads a discussion with Sophia Roberts (center), a NASA video producer who documented the Webb project, and Paul Geithner (right), former deputy project manager for NASA’s James Webb Space Telescope, following a screening of the new NASA+ documentary “Cosmic Dawn: The Untold Story of the James Webb Space Telescope,” Wednesday, June 11, 2025, at the Greenbelt Cinema in Greenbelt, Md. Featuring never-before-seen footage, Cosmic Dawn offers an unprecedented glimpse into Webb’s assembly, testing, and launch. Credit: NASA/Joel Kowsky To others who dream of pursuing a similar career, Sophia recommends diving in headfirst. “With cameras readily available and free online platforms, it’s never been easier to get into the media,” she says. “You just have to be careful to research your topic and sources, making sure you really know what you’re sharing and understand that science is always evolving as we learn more.” And Sophia emphasizes how important storytelling is for conveying information, especially when it’s as complex as astrophysics. “Studying science is wonderful, but I also think helping people visualize it is magical.” By Ashley Balzer NASA’s Goddard Space Flight Center in Greenbelt, Md.

NASA/JPL-Caltech Written by Scott VanBommel, Planetary Scientist at Washington University in St. Louis Earth planning date: Monday, June 23, 2025 Curiosity was back at work on Monday, with a full slate of activities planned. While summer has officially arrived for much of Curiosity’s team back on Earth, Mars’ eldest active rover is recently through the depths of southern Mars winter and trending toward warmer temperatures itself. Warmer temperatures mean less component heating is required and therefore more power is freed up for science and driving. However, the current cooler temperatures do present an opportunity to acquire quality short-duration APXS measurements first thing in the morning, which is what Curiosity elected to do once again. Curiosity’s plan commenced by brushing a rock target with potential cross-cutting veins, “Hornitos,” and subsequently analyzing it with APXS. A sequence of Mastcam images followed on targets such as “Volcán Peña Blanca,” “La Pacana,” “Iglesia de Jarinilla de Umatia,” and “Ayparavi.” ChemCam, returning to action after a brief and understood hiatus, rounded out the morning’s chemical analysis activities with a 5-point analysis of Ayparavi. After some images of the brush, and a handful of MAHLI snaps of Hornitos, Curiosity was on its way with a planned drive of about 37 meters (about 121 feet).Curiosity’s night would not be spent entirely dreaming of whatever rovers dream, but rather conducting a lengthy APXS analysis of the atmosphere. These analyses enable Curiosity’s team to assess the abundance of argon in the atmosphere — from a volume about the size of a pop can (or soda can, depending on your unit of preference) — which can be used to trace global circulation patterns and better understand modern Mars. Recently, Curiosity has been increasing the frequency of these measurements and pairing them with ChemCam “Passive Sky” observations. These ChemCam activities do not utilize the instrument’s laser, but instead use its other components to characterize the air above the rover. By combining APXS and ChemCam observations of the atmosphere, Curiosity’s team is able to better assess daily and seasonal trends in gases around Gale crater. A ChemCam “Passive Sky” was the primary observation in the second sol of the plan, with Curiosity spending much of the remaining time recharging and eagerly awaiting commands from Wednesday’s team.

NASA For some people, a passion for space is something that might develop over time, but for Patrick Junen, the desire was there from the beginning. With a father and grandfather who both worked for NASA, space exploration is not just a dream; it remains a family legacy. Now, as the stage assembly and structures subsystem manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the BOLE (Booster Obsolescence Life Extension) Program — an advanced solid rocket booster for NASA’s SLS (Space Launch System) heavy lift rocket — Junen is continuing that legacy. “My grandfather worked on the Apollo & Space Shuttle Programs. Then my dad went on to work for the Space Shuttle and SLS Programs,” Junen says. “I guess you could say engineering is in my blood.” In his role, he’s responsible for managing the Design, Development, Test, & Evaluation team for all unpressurized structural elements, such as the forward skirt, aft skirt, and the integration hardware that connects the boosters to the core stage. He also collaborates closely with NASA’s Exploration Ground Systems at Kennedy Space Center in Florida to coordinate any necessary modifications to ground facilities or the mobile launcher to support the new boosters. Junen enjoys the technical challenges of his role and said he feels fortunate to be in a position of leadership — but it takes a team of talented individuals to build the next generation of boosters. As a former offensive lineman for the University of Mississippi, he knows firsthand the power of teamwork and the importance of effective communication in guiding a coordinated effort. “I’ve always been drawn to team activities, and exploration is the ultimate team endeavor,” Junen says. “On the football field, it takes a strong team to be successful — and it’s really no different from what we’re doing as a team at NASA with our Northrop Grumman counterparts for the SLS rocket and Artemis missions.” As a kid, Junen often accompanied his dad to Space Shuttle launches and was inspired by some of the talented engineers that developed Shuttle. Years later, he’s still seeing some of those same faces — but now they’re teammates, working together toward a greater mission. “Growing up around Marshall Space Flight Center in Huntsville, Alabama, there was always this strong sense of family and dedication to the Misson. And that has always resonated with me,” Junen recalls. This philosophy of connecting family to the mission is a tradition Junen now continues with his own children. One of his fondest NASA memories is watching the successful launch of Artemis I on Nov. 16, 2022. Although he couldn’t attend in person, Junen and his family made the most of the moment — watching the launch live beneath the Saturn V rocket at Huntsville’s U.S. Space & Rocket Center. With his dad beside him and his daughter on his shoulders, three generations stood beneath the rocket Junen’s grandfather helped build, as a new era of space exploration began. In June, Junen witnessed the BOLE Demonstration Motor-1 perform a full-scale static test to demonstrate the ballistic performance for the evolved booster motor. This test isn’t just a technical milestone for Junen — it’s a continuation of a lifelong journey rooted in family and teamwork. As NASA explores the Moon and prepares for the journey to Mars through Artemis, Junen is helping shape the next chapter of human spaceflight. And just like the generations before him, he’s not only building rockets — he’s building a legacy.

In the 1960s, Rubin and her colleagues studied M31 and determined that there was some unseen matter in the galaxy that was affecting how the galaxy and its spiral arms rotated. This unknown material was named “dark matter.” M31 is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way.

NASA/Samuel Leblanc In autumn 2024, California’s Monterey Bay experienced an outsized phytoplankton bloom that attracted fish, dolphins, whales, seabirds, and – for a few weeks in October – scientists. A team from NASA’s Ames Research Center in Silicon Valley, with partners at the University of California, Santa Cruz (UCSC), and the Naval Postgraduate School, spent two weeks on the California coast gathering data on the atmosphere and the ocean to verify what satellites see from above. In spring 2025, the team returned to gather data under different environmental conditions. Scientists call this process validation. Setting up the Campaign The PACE mission, which stands for Plankton, Aerosol, Cloud, ocean Ecosystem, was launched in February 2024 and designed to transform our understanding of ocean and atmospheric environments. Specifically, the satellite will give scientists a finely detailed look at life near the ocean surface and the composition and abundance of aerosol particles in the atmosphere. Whenever NASA launches a new satellite, it sends validation science teams around the world to confirm that the data from instruments in space match what traditional instruments can see at the surface. AirSHARP (Airborne aSsessment of Hyperspectral Aerosol optical depth and water-leaving Reflectance Product Performance for PACE) is one of these teams, specifically deployed to validate products from the satellite’s Ocean Color Instrument (OCI). The OCI spectrometer works by measuring reflected sunlight. As sunlight bounces off of the ocean’s surface, it creates specific shades of color that researchers use to determine what is in the water column below. To validate the OCI data, research teams need to confirm that measurements directly at the surface match those from the satellite. They also need to understand how the atmosphere is changing the color of the ocean as the reflected light is traveling back to the satellite. In October 2024 and May 2025, the AirSHARP team ran simultaneous airborne and seaborne campaigns. Going into the field during different seasons allows the team to collect data under different environmental conditions, validating as much of the instrument’s range as possible. Over 13 days of flights on a Twin Otter aircraft, the NASA-led team used instruments called 4STAR-B (Spectrometer for sky-scanning sun Tracking Atmospheric Research B), and the C-AIR (Coastal Airborne In-situ Radiometer) to gather data from the air. At the same time, partners from UCSC used a host of matching instruments onboard the research vessel R/V Shana Rae to gather data from the water’s surface. Ocean Color and Water Leaving Reflectance The Ocean Color Instrument measures something called water leaving reflectance, which provides information on the microscopic composition of the water column, including water molecules, phytoplankton, and particulates like sand, inorganic materials, and even bubbles. Ocean color varies based on how these materials absorb and scatter sunlight. This is especially useful for determining the abundance and types of phytoplankton. Photographs taken out the window of the Twin Otter aircraft during the October 2024 AirSHARP deployment showcase the variation in ocean color, which indicates different molecular composition of the water column beneath. The red color in several of these photos is due to a phytoplankton bloom – in this case a growth of red algae. NASA/Samuel Leblanc The AirSHARP team used radiometers with matching technology – C-AIR from the air and C-OPS (Compact Optical Profiling System) from the water – to gather water leaving reflectance data. “The C-AIR instrument is modified from an instrument that goes on research vessels and takes measurements of the water’s surface from very close range,” said NASA Ames research scientist Samuel LeBlanc. “The issue there is that you’re very local to one area at a time. What our team has done successfully is put it on an aircraft, which enables us to span the entire Monterey Bay.” The larger PACE validation team will compare OCI measurements with observations made by the sensors much closer to the ocean to ensure that they match, and make adjustments when they don’t. Aerosol Interference One factor that can impact OCI data is the presence of manmade and natural aerosols, which interact with sunlight as it moves through the atmosphere. An aerosol refers to any solid or liquid suspended in the air, such as smoke from fires, salt from sea spray, particulates from fossil fuel emissions, desert dust, and pollen. Imagine a 420 mile-long tube, with the PACE satellite at one end and the ocean at the other. Everything inside the tube is what scientists refer to as the atmospheric column, and it is full of tiny particulates that interact with sunlight. Scientists quantify this aerosol interaction with a measurement called aerosol optical depth. “During AirSHARP, we were essentially measuring, at different wavelengths, how light is changed by the particles present in the atmosphere,” said NASA Ames research scientist Kristina Pistone. “The aerosol optical depth is a measure of light extinction, or how much light is either scattered away or absorbed by aerosol particulates.” The team measured aerosol optical depth using the 4STAR-B spectrometer, which was engineered at NASA Ames and enables scientists to identify which aerosols are present and how they interact with sunlight. Twin Otter Aircraft AirSHARP principal investigator Liane Guild walks towards a Twin Otter aircraft owned and operated by the Naval Postgraduate School. The aircraft’s ability to perform complex, low-altitude flights made it the ideal platform to fly multiple instruments over Monterey Bay during the AirSHARP campaign. NASA/Samuel Leblanc Flying these instruments required use of a Twin Otter plane, operated by the Naval Postgraduate School (NPS). The Twin Otter is unique for its ability to perform extremely low-altitude flights, making passes down to 100 feet above the water in clear conditions. “It’s an intense way to fly. At that low height, the pilots continually watch for and avoid birds, tall ships, and even wildlife like breaching whales,” said Anthony Bucholtz, director of the Airborne Research Facility at NPS. With the phytoplankton bloom attracting so much wildlife in a bay already full of ships, this is no small feat. “The pilots keep a close eye on the radar, and fly by hand,” Bucholtz said, “all while following careful flight plans crisscrossing Monterey Bay and performing tight spirals over the Research Vessel Shana Rae.” Campaign Data Data gathered from the 2024 phase of this campaign is available on two data archive systems. Data from the 4STAR instrument is available in the PACE data archive and data from C-AIR is housed in the SeaBASS data archive. Other data from the NASA PACE Validation Science Team is available through the PACE website: https://pace.oceansciences.org/pvstdoi.htm# Samuel LeBlanc and Kristina Pistone are funded via the Bay Area Environmental Research Institute (BAERI), which is a scientist-founded nonprofit focused on supporting Earth and space sciences.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Since childhood, Derrick Bailey always had an early fascination with aeronautics. Military fighter jet pilots were his childhood heroes, and he dreamed of joining the aerospace industry. This passion was a springboard into his 17-year career at NASA, where Bailey plays an important role in enabling successful rocket launches. Bailey is the Launch Vehicle Certification Manager in the Launch Services Program (LSP) within the Space Operations Mission Directorate. In this role, he helps NASA outline the agency’s risk classifications of new rockets from emerging and established space companies. “Within my role, I formulate a series of technical and process assessments for NASA LSP’s technical team to understand how companies operate, how vehicles are designed and qualified, and how they perform in flight,” Bailey said. Beyond technical proficiency and readiness, a successful rocket launch relies on establishing a strong foundational relationship between NASA and the commercial companies involved. Bailey and his team ensure effective communication with these companies to provide the guidance, data, and analysis necessary to support them in overcoming challenges. “We work diligently to build trusting relationships with commercial companies and demonstrate the value in partnering with our team,” Bailey said. Bailey credits a stroke of fate that landed him at the agency. During his senior year at Georgia Tech, where he was pursuing a degree in aerospace engineering, Bailey almost walked past the NASA tent at a career fair. However, he decided to grab a NASA sticker and strike up a conversation, which quickly turned into an impromptu interview. He walked away that day with a job offer to work on the now-retired Space Shuttle Program at the agency’s Kennedy Space Center in Florida. “I never imagined working at NASA,” Bailey said. “Looking back, it’s unbelievable that a chance encounter resulted in securing a job that has turned into an incredible career.” Thinking about the future, Bailey is excited about new opportunities in the commercial space industry. Bailey sees NASA as a crucial advisor and mentor for commercial sector while using industry capabilities to provide more cost-effective access to space. Derrick Bailey, launch vehicle certification manager for NASA’s Launch Services Program “We are the enablers,” Bailey said of his role in the directorate. “It is our responsibility to provide the best opportunity for future explorers to begin their journey of discovery in deep space and beyond.” Outside of work, Bailey enjoys spending time with his family, especially his two sons, who keep him busy with trips to the baseball diamond and homework sessions. Bailey also enjoys hands-on activities, like working on cars, off-road vehicles, and house projects – hobbies he picked up from his mechanically inclined father. Additionally, at the beginning of 2025, his wife accepted a program specialist position with LSP, an exciting development for the entire Bailey family. “One of my wife’s major observations early on in my career was how much my colleagues genuinely care about one another and empower people to make decisions,” Bailey explained. “These are the things that make NASA the number one place to work in the government.” NASA’s Space Operations Mission Directorate maintains a continuous human presence in space for the benefit of people on Earth. The programs within the directorate are the hub of NASA’s space exploration efforts, enabling Artemis, commercial space, science, and other agency missions through communication, launch services, research capabilities, and crew support.

Communicating in space usually relies on radio waves, but NASA is exploring laser, or optical, communications, which can send data 10 to 100 times faster to the ground. Instead of radio signals, these systems use infrared light to transmit high-definition video, picture, voice, and science data across vast distances in less time. NASA has proven laser communications during previous technology demonstrations, but Artemis II will be the first crewed mission to attempt using lasers to transmit data from deep space. To support this effort, researchers working on the agency’s Real Time Optical Receiver (RealTOR) project have developed a cost-effective laser transceiver using commercial-off-the-shelf parts. Earlier this year, NASA Glenn engineers built and tested a replica of the system at the center’s Aerospace Communications Facility, and they are now working with ANU to build a system with the same hardware models to prepare for the university’s Artemis II laser communications demo. “Australia’s upcoming lunar experiment could showcase the capability, affordability, and reproducibility of the deep space receiver engineered by Glenn,” said Jennifer Downey, co-principal investigator for the RealTOR project at NASA Glenn. “It’s an important step in proving the feasibility of using commercial parts to develop accessible technologies for sustainable exploration beyond Earth.” During Artemis II, which is scheduled for early 2026, NASA will fly an optical communications system aboard the Orion spacecraft, which will test using lasers to send data across the cosmos. During the mission, NASA will attempt to transmit recorded 4K ultra-high-definition video, flight procedures, pictures, science data, and voice communications from the Moon to Earth.

This ground station will serve as a test location for the new transceiver design and will not be one of the mission’s primary ground stations. If the test is successful, it will prove that commercial parts can be used to build affordable, scalable space communication systems for future missions to the Moon, Mars, and beyond. “Engaging with The Australian National University to expand commercial laser communications offerings across the world will further demonstrate how this advanced satellite communications capability is ready to support the agency’s networks and missions as we set our sights on deep space exploration,” said Marie Piasecki, technology portfolio manager for NASA’s Space Communications and Navigation (SCaN) Program. As NASA continues to investigate the feasibility of using commercial parts to engineer ground stations, Glenn researchers will continue to provide critical support in preparation for Australia’s demonstration. Strong global partnerships advance technology breakthroughs and are instrumental as NASA expands humanity’s reach from the Moon to Mars, while fueling innovations that improve life on Earth. Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

These include the LCOT (Low-Cost Optical Terminal) project, the Laser Communications Relay Demonstration, and more. NASA Glenn manages the project under the direction of agency’s SCaN Program at NASA Headquarters in Washington.

6 Min Read NASA’s Chandra Shares a New View of Our Galactic Neighbor The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way. The galaxy M31 has played an important role in many aspects of astrophysics, but particularly in the discovery of dark matter. In the 1960s, astronomer Vera Rubin and her colleagues studied M31 and determined that there was some unseen matter in the galaxy that was affecting how the galaxy and its spiral arms rotated. This unknown material was named “dark matter.” Its nature remains one of the biggest open questions in astrophysics today, one which NASA’s upcoming Nancy Grace Roman Space Telescope is designed to help answer.

Frattare, K. Arcand, J.Major Each type of light reveals new information about this close galactic relative to the Milky Way. For example, Chandra’s X-rays reveal the high-energy radiation around the supermassive black hole at the center of M31 as well as many other smaller compact and dense objects strewn across the galaxy. A recent paper about Chandra observations of M31 discusses the amount of X-rays produced by the supermassive black hole in the center of the galaxy over the last 15 years. One flare was observed in 2013, which appears to represent an amplification of the typical X-rays seen from the black hole. These multi-wavelength datasets are also being released as a sonification, which includes the same wavelengths of data in the new composite. In the sonification, the layer from each telescope has been separated out and rotated so that they stack on top of each other horizontally, beginning with X-rays at the top and then moving through ultraviolet, optical, infrared, and radio at the bottom. As the scan moves from left to right in the sonification, each type of light is mapped to a different range of notes, from lower-energy radio waves up through the high energy of X-rays. Meanwhile, the brightness of each source controls volume, and the vertical location dictates the pitch.

This collection helps astronomers understand the evolution of the Milky Way, our own spiral galaxy, and provides a fascinating insight into astronomical data gathering and presentation. Like all spiral galaxies viewed at this distance and angle, Andromeda appears relatively flat. Its spiraling arms circle around a bright core, creating a disk shape, like a large dinner plate. In most of the images in this collection, Andromeda’s flat surface is tilted to face our upper left. This collection features data from some of the world’s most powerful telescopes, each capturing light in a different spectrum. In each single-spectrum image, Andromeda has a similar shape and orientation, but the colors and details are dramatically different. In radio waves, the spiraling arms appear red and orange, like a burning, loosely coiled rope. The center appears black, with no core discernible. In infrared light, the outer arms are similarly fiery. Here, a white spiraling ring encircles a blue center with a small golden core. The optical image is hazy and grey, with spiraling arms like faded smoke rings. Here, the blackness of space is dotted with specks of light, and a small bright dot glows at the core of the galaxy. In ultraviolet light the spiraling arms are icy blue and white, with a hazy white ball at the core. No spiral arms are present in the X-ray image, making the bright golden core and nearby stars clear and easy to study. In this release, the single-spectrum images are presented side by side for easy comparison. They are also combined into a composite image. In the composite, Andromeda’s spiraling arms are the color of red wine near the outer edges, and lavender near the center. The core is large and bright, surrounded by a cluster of bright blue and green specks. Other small flecks in a variety of colors dot the galaxy, and the blackness of space surrounding it. This release also features a thirty second video, which sonifies the collected data. In the video, the single-spectrum images are stacked vertically, one atop the other. As the video plays, an activation line sweeps across the stacked images from left to right. Musical notes ring out when the line encounters light. The lower the wavelength energy, the lower the pitches of the notes. The brighter the source, the louder the volume.

Through a partnership with NASA, the lab has now used this data to model and map bird population trends for nearly 500 North American species. Led by Alison Johnston of the University of St. Andrews in Scotland, the researchers reported that 75% of bird species in the study are declining at wide-range scales. And yet this study has some good news for birds. The results, published in Science in May, offer insights and projections that could shape the future conservation of the places where birds make their homes. “This project demonstrates the power of merging in situ data with NASA remote sensing to model biological phenomena that were previously impossible to document,” said Keith Gaddis, NASA’s Biological Diversity and Ecological Forecasting program manager at the agency’s headquarters in Washington, who was not involved in the study. “This data provides not just insight into the Earth system but also provides actionable guidance to land managers to mitigate biodiversity loss.” Rock wren in Joshua Tree National Park. National Park Service / Jane Gamble A team from Cornell, the University of St. Andrews, and the American Bird Conservancy used land imaging data from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) instruments to distinguish among such specific bird habitats as open forests, dense shrublands, herbaceous croplands, and forest/cropland mosaics. They also drew on NASA weather information and water data that matched the dates and times when birders made their reports. When combined with a 14-year set of eBird checklists — 36 million sets of species observations and counts, keyed directly to habitats — the satellite data gave researchers almost a strong foundation to produce a clear picture of the health of bird populations. But there was one missing piece. Wrestling with Wren Data While some eBird checklists come from expert birders who’ve hiked deep into wildlife preserves, others are sent in by novices watching bird feeders and doing the dishes. This creates what Cornell statistician Daniel Fink described as “an unstructured, very noisy data set,” complete with gaps in the landscape that birders did not reach and, ultimately, some missing birds. To account for gaps where birds weren’t counted, the researchers trained machine learning models to fill in the maps based on the remote sensing data. “For every single species — say the rock wren — we’ve created a simulation that mimics the species and a variety of ways that it could respond to changes in the environment,” Johnston said. “Thousands of simulations underlie the results we showed.” CornellLab eBird The researchers achieved unprecedented resolution, zeroing in on areas 12 miles by 12 miles (27 km by 27 km), the same area as Portland, Oregon. This new population counting method can also be applied to eBird data from other locations, Fink said. “Now we’re using modeling to track bird populations — not seasonally through the year, but acrossthe years — a major milestone,” he added. “We’ve been able to take citizen science data and, through machine learning methodology, put it on the same footing as traditionally structured surveys, in terms of the type of signal we can find,” said Cornell science product manager Tom Auer. “It will increase the credibility and confidence of people who use this information for precise conservation all over the globe.” The Up Side Since 1970, North America has lost one-quarter of its breeding birds, following a global trend of declines across species. The causes range from increased pollution and land development to changing climate and decreased food resources. Efforts to reverse this loss depend on identifying the areas where birds live at highest risk, assessing their populations, and pinpointing locations where conservation could help most. For 83% of the reported species in the new study, the decline was greatest in spots where populations had previously been most abundant — indicating problems with the habitat. “Even in species where populations are declining a lot, there are still places of hope, where the populations are going up,” Johnston said. The team found population increases in the maps of 97% of the reported species. “That demonstrates that there’s opportunity for those species.” “Birds face so many challenges,” said Cornell conservationist Amanda Rodewald. “This research will help us make strategic decisions about making changes that are precise, effective, and less costly. This is transformative. Now we can really drill in and know where specifically we’re going to be able to have the most positive impact in trying to stem bird declines.” By Karen Romano Young NASA Headquarters, Washington Share Details Last Updated Jun 25, 2025 Related Terms Earth Moderate Resolution Imaging Spectroradiometer (MODIS) Explore More 3 min read NASA Scientists Find Ties Between Earth’s Oxygen and Magnetic Field Article 1 week ago 1 min read From Space to Soil: How NASA Sees Forests NASA uses satellite lidar technology to study Earth’s forests, key carbon sinks.

5 Min Read What Are Asteroids? (Ages 14-18) What are asteroids? Asteroids are rocky objects that orbit the Sun just like planets do. In fact, sometimes asteroids are called “minor planets.” These space rocks were left behind after our solar system formed about 4.6 billion years ago. Asteroids are found in a wide range of sizes. For example, one small asteroid, 2015 TC25, has a diameter of about 6 feet – about the size of a small car – while the asteroid Vesta is nearly 330 miles in diameter, almost as wide as the U.S. state of Arizona. Some asteroids even have enough gravity to have one or two small moons of their own. There are more than a million known asteroids. Many asteroids are given names. An organization called the International Astronomical Union is responsible for assigning names to objects like asteroids and comets. This illustration depicts NASA’s Psyche spacecraft as it approaches the asteroid Psyche. Once it arrives in 2029, the spacecraft will orbit the metal-rich asteroid for 26 months while it conducts its science investigation.NASA/JPL-Caltech/ASU What’s the difference between asteroids, meteors, and comets? Although all of these celestial bodies orbit the Sun, they are not the same. Unlike asteroids, which are rocky, comets are a mix of dust and ice. Meteors are small space rocks that get pulled close enough to enter Earth’s atmosphere, where they either burn up as a shooting star or land on the ground as a meteorite. What are asteroids made of? Different types of asteroids are composed of different mixes of materials. Most of them are made of chondrites, which are combinations of materials such as rocks and clay. These are called “C-type” asteroids. Some, called “S-type,” are made of stony materials, while “M-type” asteroids are composed of metallic elements. NASA’s Dawn spacecraft captured this image of Vesta as it left the giant asteroid’s orbit in 2012. The framing camera was looking down at the north pole, which is in the middle of the image.NASA/JPL-Caltech/UCLA/MPS/DLR/IDA How did the asteroids form? Asteroids formed around the same time and in the same way as the planets in our solar system. A massive, dense cloud of gas and dust collapsed into a spinning disk, and the gravity in the disk’s center pulled more and more material toward it. Over time, these pieces repeatedly collided with each other, sometimes resulting in smaller fragments and other times clumping together, resulting in much bigger objects. Objects with a lot of mass – like planets – produced enough gravity to pull themselves into spheres, but many smaller objects didn’t. These ended up becoming comets, small moons, and, yes, asteroids. Although some asteroids have a spherical shape, most have irregular shapes – sometimes oblong, bumpy, or jagged. The main asteroid belt lies between Mars and Jupiter, and Trojan asteroids both lead and follow Jupiter. Scientists now know that asteroids were the original “building blocks” of the inner planets. Those that remain are airless rocks that failed to adhere to one another to become larger bodies as the solar system was forming 4.6 billion years ago.Credits: NASA, ESA and J. Olmsted (STScI) Where are asteroids found? Most of the asteroids we know about are located in an area called the main asteroid belt, which is found in the space between Mars and Jupiter. But asteroids are found in other parts of the solar system, too. Trojan asteroids orbit the Sun on the same orbital path as a planet. They’re found at two specific points on the planetary orbit called Lagrange points. At these points, the gravitational pull of the planet and the Sun are in balance, making these points gravity-neutral and stable. Many planets have been found to have Trojan asteroids, including Earth. An asteroid’s location can also be influenced by the gravity of planets it passes and end up pushed or pulled onto a path that brings it close to Earth. When asteroids or comets are on an orbital path that comes within 30 million miles of Earth’s orbit, we call them near-Earth objects.

Yes! Throughout history, asteroids or pieces of asteroids have collided with Earth, our Moon, and the other planets, too. The effects of some of these impacts are still visible. For example, Chicxulub Crater was created 65 million years ago when a massive asteroid struck Mexico’s Yucatan Peninsula. The resulting cloud of dust and gas released into Earth’s atmosphere blocked sunlight, leading to a mass extinction that included the dinosaurs. More recently, in 2013, people in Chelyabinsk, Russia, witnessed an asteroid almost as wide as a tennis court explode in the atmosphere above them. That event produced a powerful shockwave that caused injuries and damaged structures. This is why NASA’s Planetary Defense Coordination Office keeps a watchful eye on near-Earth objects. The Planetary Defense team relies on telescopes and observatories on Earth and in space to detect and monitor objects like these that could stray too close to our planet. The agency is working on planetary defense strategies to use if an asteroid is discovered to be heading our way. For example, NASA’s DART (Double Asteroid Redirection Test) mission in 2022 was a first-of-its-kind test: an uncrewed spacecraft with an autonomous targeting system intentionally flew into the asteroid Dimorphos, successfully changing its orbit.

NASA detects and tracks asteroids using telescopes on the ground and in space, radar observations, and computer modeling. The agency also has launched several robotic explorers to learn more about asteroids. Some missions study asteroids from above, such as the Psyche mission, launched in 2023 to study the asteroid Psyche beginning in 2029. Other missions have actually made physical contact with asteroids. For example, the DART mission mentioned above impacted an asteroid to change its orbit, and the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) spacecraft collected a sample of material from the surface of asteroid Bennu and delivered the sample to Earth in 2023 for scientists to study. Career Corner Want a career where you get to study asteroids? Here are some jobs at NASA that do just that: Astronomer: These scientists observe and study planets, stars, and galaxies.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) With Voyager 2 in the background, John Casani holds a small U.S. flag that was sewn into the spacecraft’s thermal blankets before its 1977 launch. Then Voyager’s project manager, Casani was first to envision the mission’s Golden Record, which lies before him with its cover at right. NASA/JPL-Caltech During his work on several historic missions, Casani rose through a series of technical and management positions, making an indelible mark on the nation’s space program. John R. Casani, a visionary engineer who served a central role in many of NASA’s historic deep space missions, died on Thursday, June 19, 2025, at the age of 92. He was preceded in death by his wife of 39 years, Lynn Casani, in 2008 and is survived by five sons and their families. Casani started at the Jet Propulsion Laboratory in Southern California in 1956 and went on to work as an electronics engineer on some of the nation’s earliest spacecraft after NASA’s formation in 1958. Along with leading the design teams for both the Ranger and Mariner series of spacecraft, he held senior project positions on many of the Mariner missions to Mars and Venus, and was project manager for three trailblazing space missions: Voyager, Galileo, and Cassini. His work helped advance NASA spacecraft in areas including mechanical technology, system design and integration, software, and deep space communications. No less demanding were the management challenges of these multifaceted missions, which led to innovations still in use today. JPL’s John Casani receives the National Air & Space Museum’s Lifetime Achievement Award.Carolyn Russo/NASM, National Air and Space Museum, Smithsonian Institution “John had a major influence on the development of spacecraft that visited almost every planet in our solar system, as well as the people who helped build them,” said JPL director Dave Gallagher. “He played an essential role in America’s first attempts to reach space and then the Moon, and he was just as crucial to the Voyager spacecraft that marked humanity’s first foray into interplanetary — and later, interstellar — space. That Voyager is still exploring after nearly 50 years is a testament to John’s remarkable engineering talent and his leadership that enabled others to push the boundaries of possibility.” Born in Philadelphia in 1932, Casani studied electrical engineering at the University of Pennsylvania. After a short stint at an Air Force research lab, he moved to California in 1956 and was hired to work at JPL, a division of Caltech, on the guidance system for the U.S. Army Ballistic Missile Agency’s Jupiter-C and Sergeant missile programs. In 1957, the Soviet Union launched Sputnik 1, the first human-made Earth satellite, alarming America and changing the trajectory of both JPL and Casani’s career. With the 1958 launch of Explorer 1, America’s first satellite, the lab transitioned to concentrating on robotic space explorers, and Casani segued from missiles to spacecraft. One of his jobs as payload engineer on Pioneer 3 and 4, NASA’s first missions to the Moon, was to carry each of the 20-inch-long (51-cm-long) probes in a suitcase from JPL to the launch site at Cape Canaveral, Florida, where he installed them in the rocket’s nose cone. At the dawn of the 1960s, Casani served as spacecraft systems engineer for the agency’s first two Ranger missions to the Moon, then joined the Mariner project in 1965, earning a reputation for being meticulous. Four years later, he was Mariner project manager. Asked to share some of his wisdom in a 2009 NASA presentation, Casani said, “The thing that makes any of this work … is toughness. Toughness because this is a tough business, and it’s a very unforgiving business. You can do 1,000 things right, but if you don’t do everything right, it’ll come back and bite you.” Casani’s next role: project manager for NASA’s high-profile flagship mission to the outer planets and beyond — Voyager. He not only led the mission from clean room to space, he was first to envision attaching a message representing humanity to any alien civilization that might encounter humanity’s first interstellar emissaries. “I approached Carl Sagan,” he said in a 2007 radio interview, “and asked him if he could come up with something that would be appropriate that we could put on our spacecraft in a way of sending a message to whoever might receive it.” Sagan took up the challenge, and what resulted was the Golden Record, a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth. Once Voyager 1 and 2 and their Golden Records launched in 1977, JPL wasted no time in pointing their “engineer’s engineer” toward Galileo, which would become the first mission to orbit a gas giant planet. As the mission’s initial project manager, Casani led the effort from inception to assembly. Along the way, he had to navigate several congressional attempts to end the project, necessitating multiple visits to Washington. The 1986 loss of Space Shuttle Challenger, from which Galileo was to launch atop a Centaur upper-stage booster, led to mission redesign efforts before its 1989 launch. After 11 years leading Galileo, Casani became deputy assistant laboratory director for flight projects in 1988, received a promotion just over a year later and then, from 1990 to 1991, served as project manager of Cassini, NASA’s first flagship mission to orbit Saturn. Casani became JPL’s first chief engineer in 1994, retiring in 1999 and serving on several nationally prominent committees, including leading the investigation boards of both the Mars Climate Orbiter and the Mars Polar Lander failures, and also leading the James Webb Space Telescope Independent Comprehensive Review Panel. In early 2003, Casani returned to JPL to serve as project manager for NASA’s Project Prometheus, which would have been the nation’s first nuclear-powered, electric-propulsion spacecraft. In 2005, he became manager of the Institutional Special Projects Office at JPL, a position he held until retiring again in 2012. “Throughout his career, John reflected the true spirit of JPL: bold, innovative, visionary, and welcoming,” said Charles Elachi, JPL’s director from 2001 to 2016. “He was an undisputed leader with an upbeat, fun attitude and left an indelible mark on the laboratory and NASA. I am proud to have called him a friend.” Casani received many awards over his lifetime, including NASA’s Exceptional Achievement Medal, the Management Improvement Award from the President of the United States for the Mariner Venus Mercury mission, and the Air and Space Museum Trophy for Lifetime Achievement.

ROB Navias Public Affairs Officer and Mission Commentator Navias explained that during his time at NASA, he has learned a lot about himself. “The day you stop absorbing information, the day that you grow tired of learning new things is the day you need to walk away,” he said. “The challenge of spaceflight keeps me here at NASA.” Navias underscored the importance of nurturing and retaining the agency’s brilliant workforce who have shaped the pioneering mindset of human space exploration. He believes blending talent, resources, and industry expertise is the key to returning to the Moon and going to Mars. This collaborative mindset has not only resulted in establishing a laboratory in low Earth orbit but also paved the way for future missions. View the full article

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In addition to drilling rock core samples, the science team has been grinding its way into rocks to make sense of the scientific evidence hiding just below the surface. NASA’s Perseverance rover uses an abrading bit to get below the surface of a rocky out-crop nicknamed “Kenmore” on June 10. The eight images that make up this video were taken approximately one minute apart by one of the rover’s front hazard-avoidance cameras. NASA/JPL-Caltech On June 3, NASA’s Perseverance Mars rover ground down a portion of a rock surface, blew away the resulting debris, and then went to work studying its pristine interior with a suite of instruments designed to determine its mineralogic makeup and geologic origin. “Kenmore,” as nicknamed by the rover science team, is the 30th Martian rock that Perseverance has subjected to such in-depth scrutiny, beginning with drilling a two-inch-wide (5-centimeter-wide) abrasion patch. “Kenmore was a weird, uncooperative rock,” said Perseverance’s deputy project scientist, Ken Farley from Caltech in Pasadena, California. “Visually, it looked fine — the sort of rock we could get a good abrasion on and perhaps, if the science was right, perform a sample collection. But during abrasion, it vibrated all over the place and small chunks broke off. Fortunately, we managed to get just far enough below the surface to move forward with an analysis.” The science team wants to get below the weathered, dusty surface of Mars rocks to see important details about a rock’s composition and history. Grinding away an abrasion patch also creates a flat surface that enables Perseverance’s science instruments to get up close and personal with the rock. This close-up view of an abrasion showing distinctive “tool marks” created by the Perseverance’s abrading bit was acquired on June 5. The image was taken from approximately 2.76 inches (7 centimeters) away by the rover’s WATSON imager. NASA/JPL-Caltech/MSSS Perseverance’s gold-colored abrading bit takes center stage in this image of the rover’s drill taken by the Mastcam-Z instrument on Aug. 2, 2021, the 160th day of the mission to Mars.NASA/JPL-Caltech/ASU/MSSS Time to Grind NASA’s Mars Exploration Rovers, Spirit and Opportunity, each carried a diamond-dust-tipped grinder called the Rock Abrasion Tool (RAT) that spun at 3,000 revolutions per minute as the rover’s robotic arm pushed it deeper into the rock. Two wire brushes then swept the resulting debris, or tailings, out of the way. The agency’s Curiosity rover carries a Dust Removal Tool, whose wire bristles sweep dust from the rock’s surface before the rover drills into the rock. Perseverance, meanwhile, relies on a purpose-built abrading bit, and it clears the tailings with a device that surpasses wire brushes: the gaseous Dust Removal Tool, or gDRT. “We use Perseverance’s gDRT to fire a 12-pounds-per-square-inch (about 83 kilopascals) puff of nitrogen at the tailings and dust that cover a freshly abraded rock,” said Kyle Kaplan, a robotic engineer at NASA’s Jet Propulsion Laboratory in Southern California. “Five puffs per abrasion — one to vent the tanks and four to clear the abrasion. And gDRT has a long way to go. Since landing at Jezero Crater over four years ago, we’ve puffed 169 times. There are roughly 800 puffs remaining in the tank.” The gDRT offers a key advantage over a brushing approach: It avoids any terrestrial contaminants that might be on a brush from getting on the Martian rock being studied.

The tool fires puffs of nitrogen gas at the tailings and dust that cover a rock after it has been abraded by the rover.NASA/JPL-Caltech Having collected data on abraded surfaces more than 30 times, the rover team has in-situ science (studying something in its original place or position) collection pretty much down. After gDRT blows the tailings away, the rover’s WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) imager (which, like gDRT, is at the end of the rover’s arm) swoops in for close-up photos. Then, from its vantage point high on the rover’s mast, SuperCam fires thousands of individual pulses from its laser, each time using a spectrometer to determine the makeup of the plume of microscopic material liberated after every zap. SuperCam also employs a different spectrometer to analyze the visible and infrared light that bounces off the materials in the abraded area. “SuperCam made observations in the abrasion patch and of the powdered tailings next to the patch,” said SuperCam team member and “Crater Rim” campaign science lead, Cathy Quantin-Nataf of the University of Lyon in France. “The tailings showed us that this rock contains clay minerals, which contain water as hydroxide molecules bound with iron and magnesium — relatively typical of ancient Mars clay minerals. The abrasion spectra gave us the chemical composition of the rock, showing enhancements in iron and magnesium.” Later, the SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) and PIXL (Planetary Instrument for X-ray Lithochemistry) instruments took a crack at Kenmore, too. Along with supporting SuperCam’s discoveries that the rock contained clay, they detected feldspar (the mineral that makes much of the Moon brilliantly bright in sunlight). The PIXL instrument also detected a manganese hydroxide mineral in the abrasion — the first time this type of material has been identified during the mission. With Kenmore data collection complete, the rover headed off to new territories to explore rocks — both cooperative and uncooperative — along the rim of Jezero Crater. “One thing you learn early working on Mars rover missions is that not all Mars rocks are created equal,” said Farley. “The data we obtain now from rocks like Kenmore will help future missions so they don’t have to think about weird, uncooperative rocks. Instead, they’ll have a much better idea whether you can easily drive over it, sample it, separate the hydrogen and oxygen contained inside for fuel, or if it would be suitable to use as construction material for a habitat.” Long-Haul Roving On June 19 (the 1,540th Martian day, or sol, of the mission), Perseverance bested its previous record for distance traveled in a single autonomous drive, trekking 1,348 feet (411 meters). That’s about 210 feet (64 meters) more than its previous record, set on April 3, 2023 (Sol 753). While planners map out the rover’s general routes, Perseverance can cut down driving time between areas of scientific interest by using its self-driving system, AutoNav. “Perseverance drove 4½ football fields and could have gone even farther, but that was where the science team wanted us to stop,” said Camden Miller, a rover driver for Perseverance at JPL. “And we absolutely nailed our stop target location. Every day operating on Mars, we learn more on how to get the most out of our rover. And what we learn today future Mars missions won’t have to learn tomorrow.” News Media Contact DC Agle Jet Propulsion Laboratory, Pasadena, Calif. 818-393-9011 agle@jpl.nasa.gov Karen Fox / Molly Wasser NASA Headquarters, Washington 202-358-1600 karen.c.fox@nasa.gov / molly.l.wasser@nasa.gov 2025-082 Share Details Last Updated Jun 25, 2025 Related TermsPerseverance (Rover)Jet Propulsion LaboratoryMars Explore More 5 min read NASA’s Curiosity Mars Rover Starts Unpacking Boxwork Formations Article 2 days ago 4 min read NASA Mars Orbiter Captures Volcano Peeking Above Morning Cloud Tops Article 3 weeks ago 6 min read NASA’s Ready-to-Use Dataset Details Land Motion Across North America Article 3 weeks ago Keep Exploring Discover Related Topics Missions Humans in Space Climate Change Solar System View the full article
