Acting NASA Administrator Reflects on Legacy of Astronaut Jim Lovell
The following is a statement from acting NASA Administrator Sean Duffy on the passing of famed Apollo astronaut Jim Lovell. He passed away Aug. 7, in Lake Forest, Illinois. He was 97 years old.
“NASA sends its condolences to the family of Capt. Jim Lovell, whose life and work inspired millions of people across the decades. Jim’s character and steadfast courage helped our nation reach the Moon and turned a potential tragedy into a success from which we learned an enormous amount. We mourn his passing even as we celebrate his achievements.
“From a pair of pioneering Gemini missions to the successes of Apollo, Jim helped our nation forge a historic path in space that carries us forward to upcoming Artemis missions to the Moon and beyond.
“As the Command Module Pilot for Apollo 8, Jim and his crewmates became the first to lift off on a Saturn V rocket and orbit the Moon, proving that the lunar landing was within our reach. As commander of the Apollo 13 mission, his calm strength under pressure helped return the crew safely to Earth and demonstrated the quick thinking and innovation that informed future NASA missions.
“Known for his wit, this unforgettable astronaut was nicknamed Smilin’ Jim by his fellow astronauts because he was quick with a grin when he had a particularly funny comeback.
“Jim also served our country in the military, and the Navy has lost a proud academy graduate and test pilot. Jim Lovell embodied the bold resolve and optimism of both past and future explorers, and we will remember him always.”

NASA Invites Media to View Heliophysics, NOAA Space Weather Missions
NASA invites media to view the agency’s IMAP (Interstellar Mapping and Acceleration Probe) spacecraft and two other missions — the Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On–Lagrange 1 (SWFO-L1) observatory, which will launch along with IMAP as rideshares.
Media will have the opportunity to photograph the three spacecraft and speak with subject matter experts representing all three missions. The event will take place on Thursday, Aug. 28, at the Astrotech Space Operations payload processing facility in Titusville, Florida. Confirmed media will receive additional details after registering.
To participate in the event, media must RSVP by 11:59 p.m. on Tuesday, Aug. 19, by submitting their request online at: https://media.ksc.nasa.gov.
The IMAP mission will study the heliosphere, a vast magnetic bubble created by the Sun that protects our solar system from radiation incoming from interstellar space. Carruthers will use its ultraviolet cameras to monitor how material from the Sun impacts the outermost part of Earth’s atmosphere. The SWFO-L1 mission will observe solar eruptions, and monitor incoming space weather 24/7, providing early warnings and validating forecasts that protect vital communication and navigation infrastructure, economic interests, and national security, both on Earth and in space.
NASA is targeting no earlier than September for the launch of these three missions on a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.
NASA’s media accreditation policy is available online. For questions about accreditation, please email: ksc-media-accreditat@mail.nasa.gov.
Facility Access
Due to spacecraft cleanliness requirements, this invitation is open to a limited number of media with no more than two individuals per media organization. This event is open to U.S. citizens who possess a valid government-issued photo identification and proof of U.S. citizenship, such as a passport or birth certificate.
Media attending this event must comply with cleanroom guidelines. This includes wearing specific cleanroom garments; avoiding cologne, cosmetics, and high-heeled shoes; cleaning camera equipment under the supervision or assistance of contamination control specialists; and placing all electronics in airplane mode in the designated areas near the spacecraft. NASA will provide detailed guidance to approved media.
Observatories Information
The three observatories are preparing to launch to Lagrange point 1, which lies about a million miles from Earth toward the Sun. There, they will orbit this gravitational balance point, holding a steady position between Earth and the Sun. NASA’s IMAP will use its 10 instruments to map the heliosphere’s edge and reveal how the Sun accelerates charged particles, filling in essential puzzle pieces to understand the space weather environment across the solar system. The mission’s varied instruments also will provide near real-time space weather data to scientists on Earth.
The Carruthers observatory will image the glow of ultraviolet light emitted by the uppermost parts of Earth’s atmosphere — called the geocorona — to help researchers understand how our planet’s atmosphere is shaped by conditions in space. NOAA’s SWFO-L1 will use its suite of instruments to sample the solar wind and interplanetary magnetic field, while its onboard coronagraph will detect coronal mass ejections and other solar events. Together, these real-time observations of space weather enable precautionary actions to protect satellites, power grids, aviation, and communication and navigation technology.

Rare Type of Black Hole Snacks on Star
NASA’s Hubble Space Telescope and NASA’s Chandra X-ray Observatory teamed up to identify a new possible example of a rare class of black holes, identified by X-ray emission (in purple) in this image released on July 24, 2025. Called NGC 6099 HLX-1, this bright X-ray source seems to reside in a compact star cluster in a giant elliptical galaxy. These rare black holes are called intermediate-mass black holes (IMBHs) and weigh between a few hundred to a few 100,000 times the mass of our Sun.

Hubble Captures a Tarantula This NASA/ESA Hubble Space Telescope image shows a portion of the Tarantula Nebula. ESA/Hubble & NASA, C. MurrayThis NASA/ESA Hubble Space Telescope image captures incredible details in the dusty clouds of a star-forming factory called the Tarantula Nebula. Most of the nebulae Hubble images are in our galaxy, but this nebula is in the Large Magellanic Cloud, a dwarf galaxy located about 160,000 light-years away in the constellations Dorado and Mensa.
The Large Magellanic Cloud is the largest of the dozens of small satellite galaxies that orbit the Milky Way. The Tarantula Nebula is the largest and brightest star-forming region, not just in the Large Magellanic Cloud, but in the entire group of nearby galaxies to which the Milky Way belongs.
The Tarantula Nebula is home to the most massive stars known, some roughly 200 times as massive as our Sun. This image is very close to a rare type of star called a Wolf–Rayet star. Wolf–Rayet stars are massive stars that have lost their outer shell of hydrogen and are extremely hot and luminous, powering dense and furious stellar winds.
This nebula is a frequent target for Hubble, whose multiwavelength capabilities are critical for capturing sculptural details in the nebula’s dusty clouds. The data used to create this image come from an observing program called Scylla, named for a multi-headed sea monster from Greek mythology. The Scylla program was designed to complement another Hubble observing program called ULLYSES (Ultraviolet Legacy Library of Young Stars as Essential Standards). ULLYSES targets massive young stars in the Small and Large Magellanic Clouds, while Scylla investigates the structures of gas and dust that surround these stars.

Linking Local Lithologies to a Larger Landscape This image from NASA’s Mars Perseverance rover, taken by the Mastcam-Z instrument’s right eye, shows a collection of ridge-forming boulders. The rover acquired this image looking south along the ridge while exploring the “Westport” region of the outer crater rim on July 18, 2025 — Sol 1568, or Martian day 1,568 of the Mars 2020 mission — at the local mean solar time of 11:53:04. NASA/JPL-Caltech/ASUWritten by Margaret Deahn, Ph.D. Student at Purdue University
NASA’s Mars 2020 rover is continuing to explore a boundary visible from orbit dividing bright, fractured outcrop from darker, smoother regolith (also known as a contact). The team has called this region “Westport,” (a fitting title, as the rover is exploring the western-most rim of Jezero), which hosts a contact between the smoother, clay-bearing “Krokodillen” unit and an outcrop of olivine-bearing boulders that converge to form a ridge on the outer Jezero crater rim. To learn more about the nature of this contact, see this blog post by Dr. Melissa Rice. Piecing together geologic events like the formation of this olivine-bearing material on Jezero’s crater rim may allow us to better understand Mars’ most ancient history.
The rover has encountered several olivine-bearing rocks while traversing the rim, but it is unclear if, and how these rocks are all connected. Jezero crater is in a region of Mars known as Northeast Syrtis, which hosts the largest contiguous exposure (more than 113,000 square kilometers, or more than 43,600 square miles) of olivine-rich material identified from orbit on Mars (about the same square mileage as the state of Ohio!). The olivine-rich materials are typically found draping over older rocks, often infilling depressions, which may provide clues to their origins. Possible origins for the olivine-rich materials in Northeast Syrtis may include (but are not limited to): (1) intrusive igneous rocks (rocks that cool from magma underground), (2) melt formed and deposited during an impact event, or (3) pyroclastic ash fall or flow from a volcanic eruption.
The Perseverance rover’s investigation of the olivine-bearing materials on the rim of Jezero crater may allow us to better constrain the history of the broader volcanic units present in the Northeast Syrtis region. Olivine-rich material in Northeast Syrtis is consistently sandwiched between older, clay-rich rock and younger, more olivine-poor material (commonly referred to as the “mafic capping” unit), and may act as an important marker for recording early alteration by water, which could help us understand early habitable environments on Mars. We see potential evidence of all of these units on Jezero crater’s rim based on orbital mapping. If the olivine-bearing rocks the Perseverance rover is encountering on the rim are related to these materials, we may be able to better constrain the age of this widespread geologic unit on Mars.

US-French SWOT Satellite Measures Tsunami After Massive Quake
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) The SWOT satellite caught the leading edge of the tsunami wave (red) that rolled through the Pacific Ocean on July 30. Sea level data, shown in the highlighted swath, is plotted against a NOAA tsunami forecast model in the background. A red star marks the location of the earthquake that spawned the tsunami.NASA/JPL-CaltechData provided by the water satellite, a joint effort between NASA and the French space agency, is helping to improve tsunami forecast models, benefitting coastal communities.
The SWOT (Surface Water and Ocean Topography) satellite captured the tsunami spawned by an 8.8 magnitude earthquake off the coast of Russia’s Kamchatka Peninsula on July 30, 11:25 a.m. local time. The satellite, a joint effort between NASA and the French space agency CNES (Centre National d’Études Spatiales), recorded the tsunami about 70 minutes after the earthquake struck.
Disturbances like an earthquake or underwater landslide trigger a tsunami when the event is large enough to displace the entire column of seawater from the ocean floor to the surface. This results in waves that ripple out from the disturbance much like dropping a pebble into a pond generates a series of waves.
“The power of SWOT’s broad, paintbrush-like strokes over the ocean is in providing crucial real-world validation, unlocking new physics, and marking a leap towards more accurate early warnings and safer futures,” said Nadya Vinogradova Shiffer, NASA Earth lead and SWOT program scientist at NASA Headquarters in Washington.
This visualization depicts the leading edge of the tsunami based on sea surface height data from SWOT looking from south to north, when the leading edge was more than 1.5 feet (45 centimeters) high, east of Japan in the Pacific Ocean.NASA/JPL-CaltechData from SWOT provided a multidimensional look at the leading edge of the tsunami wave triggered by the Kamchatka earthquake. The measurements included a wave height exceeding 1.5 feet (45 centimeters), shown in red in the highlighted track, as well as a look at the shape and direction of travel of the leading edge of the tsunami. The SWOT data, shown in the highlighted swath running from the southwest to the northeast in the visual, is plotted against a forecast model of the tsunami produced by the U.S. National Oceanic and Atmospheric Administration (NOAA) Center for Tsunami Research. Comparing the observations from SWOT to the model helps forecasters validate their model, ensuring its accuracy.
“A 1.5-foot-tall wave might not seem like much, but tsunamis are waves that extend from the seafloor to the ocean’s surface,” said Ben Hamlington, an oceanographer at NASA’s Jet Propulsion Laboratory in Southern California. “What might only be a foot or two in the open ocean can become a 30-foot wave in shallower water at the coast.”
The tsunami measurements SWOT collected are helping scientists at NOAA’s Center for Tsunami Research improve their tsunami forecast model. Based on outputs from that model, NOAA sends out alerts to coastal communities potentially in the path of a tsunami. The model uses a set of earthquake-tsunami scenarios based on past observations as well as real-time observations from sensors in the ocean.
The SWOT data on the height, shape, and direction of the tsunami wave is key to improving these types of forecast models. “The satellite observations help researchers to better reverse engineer the cause of a tsunami, and in this case, they also showed us that NOAA’s tsunami forecast was right on the money,” said Josh Willis, a JPL oceanographer.
The NOAA Center for Tsunami Research tested their model with SWOT’s tsunami data, and the results were exciting, said Vasily Titov, the center’s chief scientist in Seattle. “It suggests SWOT data could significantly enhance operational tsunami forecasts — a capability sought since the 2004 Sumatra event.” The tsunami generated by that devastating quake killed thousands of people and caused widespread damage in Indonesia.
More About SWOTThe SWOT satellite was jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and the UK Space Agency. NASA JPL, managed for the agency by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system payload, NASA provided the Ka-band radar interferometer (KaRIn) instrument, a GPS science receiver, a laser retroreflector, a two-beam microwave radiometer, and NASA instrument operations. The Doppler Orbitography and Radioposition Integrated by Satellite system, the dual frequency Poseidon altimeter (developed by Thales Alenia Space), the KaRIn radio-frequency subsystem (together with Thales Alenia Space and with support from the UK Space Agency), the satellite platform, and ground operations were provided by CNES. The KaRIn high-power transmitter assembly was provided by CSA.

NASA Uses Wind Tunnel to Test Advanced Air Mobility Aircraft Wing
3 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA employees Broderic J. Gonzalez, left, and David W. Shank install pieces of a 7-foot wing model in preparation for testing in the 14-by-22-Foot Subsonic Wind Tunnel at NASA’s Langley Research Center in Hampton, Virginia, in May 2025. The lessons learned will be shared with the public to support advanced air mobility aircraft development. NASA/Mark KnoppThe advanced air mobility industry is currently working to produce novel aircraft ranging from air taxis to autonomous cargo drones, and all of those designs will require extensive testing – which is why NASA is working to give them a head-start by studying a special kind of model wing. The wing is a scale model of a design used in a type of aircraft called a “tiltwing,” which can swing its wing and rotors from vertical to horizontal. This allows the aircraft to take off, hover, and land like a helicopter, or fly like a fixed-wing airplane. This design enables versatility in a range of operating environments.
Several companies are working on tiltwings, but NASA’s research into the scale wing will also impact nearly all types of advanced air mobility aircraft designs.
“NASA research supporting advanced air mobility demonstrates the agency’s commitment to supporting this rapidly growing industry,” said Brandon Litherland, principal investigator for the test at NASA’s Langley Research Center in Hampton, Virginia. “Tool improvements in these areas will greatly improve our ability to accurately predict the performance of new advanced air mobility aircraft, which supports the adoption of promising designs. Gaining confidence through testing ensures we can identify safe operating conditions for these new aircraft.”
NASA researcher Norman W. Schaeffler adjusts a propellor, which is part of a 7-foot wing model that was recently tested at NASA’s Langley Research Center in Hampton, Virginia. In May and June, NASA researchers tested the wing in the 14-by-22-Foot Subsonic Wind Tunnel to collect data on critical propeller-wing interactions. The lessons learned will be shared with the public to support advanced air mobility aircraft development.NASA/Mark KnoppIn May and June, NASA tested a 7-foot wing model with multiple propellers in the 14-by-22-Foot Subsonic Wind Tunnel at Langley. The model is a “semispan,” or the right half of a complete wing. Understanding how multiple propellers and the wing interact under various speeds and conditions provides valuable insight for the advanced air mobility industry. This information supports improved aircraft designs and enhances the analysis tools used to assess the safety of future designs.
This work is managed by the Revolutionary Vertical Lift Technology project under NASA’s Advanced Air Vehicles Program in support of NASA’s Advanced Air Mobility mission, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.
“This tiltwing test provides a unique database to validate the next generation of design tools for use by the broader advanced air mobility community,” said Norm Schaeffler, the test director, based at Langley. “Having design tools validated for a broad range of aircraft will accelerate future design cycles and enable informed decisions about aerodynamic and acoustic performance.”
In May and June, NASA researchers tested a 7-foot wing model in the 14-by-22-Foot Subsonic Wind Tunnel at NASA’s Langley Research Center in Hampton, Virginia. The team collected data on critical propeller-wing interactions over the course of several weeks.NASA/Mark KnoppThe wing is outfitted with over 700 sensors designed to measure pressure distribution, along with several other types of tools to help researchers collect data from the wing and propeller interactions. The wing is mounted on special sensors to measure the forces applied to the model. Sensors in each motor-propeller hub to measure the forces acting on the components independently.
The model was mounted on a turntable inside the wind tunnel, so the team could collect data at different wing tilt angles, flap positions, and rotation rates. The team also varied the tunnel wind speed and adjusted the relative positions of the propellers.
Researchers collected data relevant to cruise, hover, and transition conditions for advanced air mobility aircraft. Once they analyze this data, the information will be released to industry on NASA’s website.

Astronomers using NASA’s James Webb Space Telescope have found strong evidence of a giant planet orbiting a star in the stellar system closest to our own Sun. At just 4 light-years away from Earth, the Alpha Centauri triple star system has long been a compelling target in the search for worlds beyond our solar system.
Alpha Centauri, located in the far southern sky, is made up of the binary Alpha Centauri A and Alpha Centauri B, both Sun-like stars, and the faint red dwarf star Proxima Centauri. Alpha Centauri A is the third brightest star in the night sky. While there are three confirmed planets orbiting Proxima Centauri, the presence of other worlds surrounding Alpha Centauri A and Alpha Centauri B has proved challenging to confirm.
Now, Webb’s observations from its Mid-Infrared Instrument (MIRI) are providing the strongest evidence to date of a gas giant orbiting Alpha Centauri A. The results have been accepted in a series of two papers in The Astrophysical Journal Letters.
If confirmed, the planet would be the closest to Earth that orbits in the habitable zone of a Sun-like star. However, because the planet candidate is a gas giant, scientists say it would not support life as we know it.
“With this system being so close to us, any exoplanets found would offer our best opportunity to collect data on planetary systems other than our own. Yet, these are incredibly challenging observations to make, even with the world’s most powerful space telescope, because these stars are so bright, close, and move across the sky quickly,” said Charles Beichman, NASA’s Jet Propulsion Laboratory and the NASA Exoplanet Science Institute at Caltech’s IPAC astronomy center, co-first author on the new papers. “Webb was designed and optimized to find the most distant galaxies in the universe. The operations team at the Space Telescope Science Institute had to come up with a custom observing sequence just for this target, and their extra effort paid off spectacularly.”
Image A: Alpha Centauri 3 Panel (DSS, Hubble, Webb) This image shows the Alpha Centauri star system from several different ground- and space-based observatories: the Digitized Sky Survey (DSS), NASA’s Hubble Space Telescope, and NASA’s James Webb Space Telescope. Alpha Centauri A is the third brightest star in the night sky, and the closest Sun-like star to Earth. The ground-based image from DSS shows the triple system as a single source of light, while Hubble resolves the two Sun-like stars in the system, Alpha Centauri A and Alpha Centauri B. The image from Webb’s MIRI (Mid-Infrared Instrument), which uses a coronagraphic mask to block the bright glare from Alpha Centauri A, reveals a potential planet orbiting the star. Science: NASA, ESA, CSA, STScI, DSS, A. Sanghi (Caltech), C. Beichman (NExScI, NASA/JPL-Caltech), D. Mawet (Caltech); Image Processing: J. DePasquale (STScI)Several rounds of meticulously planned observations by Webb, careful analysis by the research team, and extensive computer modeling helped determine that the source seen in Webb’s image is likely to be a planet, and not a background object (like a galaxy), foreground object (a passing asteroid), or other detector or image artifact.
The first observations of the system took place in August 2024, using the coronagraphic mask aboard MIRI to block Alpha Centauri A’s light. While extra brightness from the nearby companion star Alpha Centauri B complicated the analysis, the team was able to subtract out the light from both stars to reveal an object over 10,000 times fainter than Alpha Centauri A, separated from the star by about two times the distance between the Sun and Earth.
Image B: Alpha Centauri 3 Panel (Webb MIRI Image Detail) This three-panel image captures NASA’s James Webb Space Telescope’s observational search for a planet around the nearest Sun-like star, Alpha Centauri A. The initial image shows the bright glare of Alpha Centauri A and Alpha Centauri B, and the middle panel then shows the system with a coronagraphic mask placed over Alpha Centauri A to block its bright glare. However, the way the light bends around the edges of the coronagraph creates ripples of light in the surrounding space. The telescope’s optics (its mirrors and support structures) cause some light to interfere with itself, producing circular and spoke-like patterns. These complex light patterns, along with light from the nearby Alpha Centauri B, make it incredibly difficult to spot faint planets. In the panel at the right, astronomers have subtracted the known patterns (using reference images and algorithms) to clean up the image and reveal faint sources like the candidate planet. Science: NASA, ESA, CSA, STScI, A. Sanghi (Caltech), C. Beichman (NExScI, NASA/JPL-Caltech), D. Mawet (Caltech); Image Processing: J. DePasquale (STScI)While the initial detection was exciting, the research team needed more data to come to a firm conclusion. However, additional observations of the system in February 2025 and April 2025 (using Director’s Discretionary Time) did not reveal any objects like the one identified in August 2024.
“We are faced with the case of a disappearing planet! To investigate this mystery, we used computer models to simulate millions of potential orbits, incorporating the knowledge gained when we saw the planet, as well as when we did not,” said PhD student Aniket Sanghi of Caltech in Pasadena, California. Sanghi is a co-first author on the two papers covering the team’s research.
In these simulations, the team took into account both a 2019 sighting of the potential exoplanet candidate by the European Southern Observatory’s Very Large Telescope, the new data from Webb, and considered orbits that would be gravitationally stable in the presence of Alpha Centauri B, meaning the planet wouldn’t get flung out of the system.
Researchers say a non-detection in the second and third round of observations with Webb isn’t surprising.
“We found that in half of the possible orbits simulated, the planet moved too close to the star and wouldn’t have been visible to Webb in both February and April 2025,” said Sanghi.
Image C: Alpha Centauri A Planet Candidate (Artist’s Concept) This artist’s concept shows what a gas giant orbiting Alpha Centauri A could look like. Observations of the triple star system Alpha Centauri using NASA’s James Webb Space Telescope indicate the potential gas giant, about the mass of Saturn, orbiting the star by about two times the distance between the Sun and Earth. In this concept, Alpha Centauri A is depicted at the upper left of the planet, while the other Sun-like star in the system, Alpha Centauri B, is at the upper right. Our Sun is shown as a small dot of light between those two stars. Artwork: NASA, ESA, CSA, STScI, R. Hurt (Caltech/IPAC)Based on the brightness of the planet in the mid-infrared observations and the orbit simulations, researchers say it could be a gas giant approximately the mass of Saturn orbiting Alpha Centauri A in an elliptical path varying between 1 to 2 times the distance between Sun and Earth.
“If confirmed, the potential planet seen in the Webb image of Alpha Centauri A would mark a new milestone for exoplanet imaging efforts,” Sanghi says. “Of all the directly imaged planets, this would be the closest to its star seen so far. It’s also the most similar in temperature and age to the giant planets in our solar system, and nearest to our home, Earth,” he says. “Its very existence in a system of two closely separated stars would challenge our understanding of how planets form, survive, and evolve in chaotic environments.”
If confirmed by additional observations, the team’s results could transform the future of exoplanet science.
“This would become a touchstone object for exoplanet science, with multiple opportunities for detailed characterization by Webb and other observatories,” said Beichman.
For example, NASA’s Nancy Grace Roman Space Telescope, set to launch by May 2027 and potentially as early as fall 2026, is equipped with dedicated hardware that will test new technologies to observe binary systems like Alpha Centauri in search of other worlds. Roman’s visible light data would complement Webb’s infrared observations, yielding unique insights on the size and reflectivity of the planet.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Preparations for Next Moonwalk Simulations Underway (and Underwater) From left to right, Astronaut Tracy Dyson, Jeremy Shidner, Sara R. Wilson, and Christopher Broadaway pose for a photo after the 2025 Silver Snoopy Awards ceremony. NASA/Mark KnoppThree employees from NASA’s Langley Research Center in Hampton, Virginia recently earned the Silver Snoopy award, a prestigious honor given to NASA employees and contractors across the agency for exceptional achievements related to spaceflight safety or mission success. Christopher Broadaway, Jeremy Shidner, and Sara Wilson received the awards during a ceremony held at the center on July 22.
The Silver Snoopy award is given personally by NASA astronauts and is presented to less than one percent of the agency’s workforce annually. The award is one of several overseen by the Space Flight Awareness (SFA) Program at NASA. Established in 1963, the SFA Program is vital in ensuring quality and flight safety of America’s space program. The SFA Program works to highlight the individuals behind the success of NASA’s programs as well as motivate the next generation of innovators and cosmic explorers.
Astronaut Tracy Dyson visited Langley to present the Silver Snoopy lapel pin and a framed Silver Snoopy certificate. Dyson flew aboard the space shuttle Endeavor on STS-118, served as flight engineer for Expedition 23/24, and conducted hundreds of hours of scientific investigations aboard the International Space Station for Expedition 70/71. She has spent a total of 373 days in space and dedicated over 23 hours to spacewalks.
As a flight engineer with substantial experience, Dyson understands the importance of space flight safety.
“Those who are receiving this award didn’t do it because they came nine to five and left. It’s not because it was just their job,” she said. “It’s because it’s their life, and our lives are safer and better for it.”
Astronaut Tracy Dyson signs certificates of appreciation prior to the 2025 Silver Snoopy Awards ceremony. NASA/Mark KnoppSilver Snoopy recipient and aerospace engineer Jeremey Shidner echoed Dyson’s perspective.
“This level of trust is particularly profound because astronauts understand better than anyone the countless systems, procedures, and people that must work flawlessly for a mission to succeed,” he said. “When astronauts single someone out for recognition, it reflects their confidence that this person embodies the same commitment to excellence and safety that they themselves must maintain.”
The prestigious award consists of a certificate of appreciation signed by Dyson, an authentication letter, and a miniature sterling silver lapel pin in the shape of the well-loved character Snoopy from the comic strip “Peanuts.” Each pin awarded has flown in space. The pins awarded to Langley’s recipients flew aboard STS-118.
The 2025 Silver Snoopy Award pins NASA/Mark KnoppHere are the three award recipients from Langley and their achievements:
Christopher Broadaway: For exemplary support in assisting the Commercial Crew Program ensure safety and mission success in industry partners’ human spaceflight missions.
Jeremy Shidner: For significant contributions to the Commercial Crew Program to ensure flight safety and mission success for Entry, Descent, and Landing. Collaborating closely with the Crew Flight Test team and Mission Operations Flight Dynamics Officers, he refined the simulation model to incorporate real pilot performance data, which resulted in increased entry accuracy, eliminating an elevated risk to crew safety.
Sara R. Wilson: For engineering excellence in the application of advanced statistical tools and methods characterizing NASA’s human spaceflight missions. She also played a key role in developing standardized tests for advanced lunar spacesuit gloves, creating consistency in evaluating materials for extreme lunar environments.

As NASA Missions Study Interstellar Comet, Hubble Makes Size Estimate Hubble captured this image of the interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus. Image: NASA, ESA, David Jewitt (UCLA); Image Processing: Joseph DePasquale (STScI)A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS using the crisp vision of NASA’s Hubble Space Telescope. Hubble is one of many missions across NASA’s fleet of space telescopes slated to observe this comet, together providing more information about its size and physical properties. While the comet poses no threat to Earth, NASA’s space telescopes help support the agency’s ongoing mission to find, track, and better understand near-Earth objects.
Hubble’s observations allow astronomers to more accurately estimate the size of the comet’s solid, icy nucleus. The upper limit on the diameter of the nucleus is 3.5 miles (5.6 kilometers), though it could be as small as 1,000 feet (320 meters) across, researchers report. Though the Hubble images put tighter constraints on the size of the nucleus compared to previous ground-based estimates, the solid heart of the comet presently cannot be directly seen, even by Hubble. Observations from other NASA missions including the James Webb Space Telescope, TESS (Transiting Exoplanet Survey Satellite), and the Neil Gehrels Swift Observatory, as well as NASA’s partnership with the W.M. Keck Observatory, will help further refine our knowledge about the comet, including its chemical makeup.
Hubble also captured a dust plume ejected from the Sun-warmed side of the comet, and the hint of a dust tail streaming away from the nucleus. Hubble’s data yields a dust-loss rate consistent with comets that are first detected around 300 million miles from the Sun. This behavior is much like the signature of previously seen Sun-bound comets originating within our solar system.
The big difference is that this interstellar visitor originated in some other solar system elsewhere in our Milky Way galaxy.
3I/ATLAS is traveling through our solar system at a staggering 130,000 miles (209,000 kilometers) per hour, the highest velocity ever recorded for a solar system visitor. This breathtaking sprint is evidence that the comet has been drifting through interstellar space for many billions of years. The gravitational slingshot effect from innumerable stars and nebulae the comet passed added momentum, ratcheting up its speed. The longer 3I/ATLAS was out in space, the higher its speed grew.
“No one knows where the comet came from. It’s like glimpsing a rifle bullet for a thousandth of a second. You can’t project that back with any accuracy to figure out where it started on its path,” said David Jewitt of the University of California, Los Angeles, science team leader for the Hubble observations.
The paper will be published in The Astrophysical Journal Letters. It is already available on Astro-ph.
New Evidence for Population of Wandering Space Relics“This latest interstellar tourist is one of a previously undetected population of objects bursting onto the scene that will gradually emerge,” said Jewitt. “This is now possible because we have powerful sky survey capabilities that we didn’t have before. We’ve crossed a threshold.”
This comet was discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) on July 1, 2025, at a distance of 420 million miles from the Sun. ATLAS is an asteroid impact early warning system developed by the University of Hawai’i.
In the meantime, other NASA missions will provide new insight into this third interstellar interloper, helping refine our understanding of these objects for the benefit of all. 3I/ATLAS should remain visible to ground-based telescopes through September, after which it will pass too close to the Sun to observe, and is expected to reappear on the other side of the Sun by early December.
The Hubble Space Telescope has been operating for more than three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

Wade Sisler: Aficionado of Wonder Serving the Cosmos
Across 42 years at NASA, Wade Sisler — executive producer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland—watched the edge of human knowledge progress. During that time, the tools for visualizing and communicating those discoveries evolved just as rapidly.
Executive Producer Wade Sisler has worked at NASA for 42 years, starting at the agency’s Ames Research Center in California’s Silicon Valley, and now at Goddard Space Flight Center in Greenbelt, Md.Credit: Courtesy of Wade Sisler“I’ve spent my career surrounded by people with amazing curiosity and intellect, pursuing questions that could change the way we see the universe, both literally and metaphorically,” Sisler said.
From his start as a student photographer at NASA’s Ames Research Center in California’s Silicon Valley, Sisler ultimately became a creative force behind some of NASA’s most iconic science storytelling. He transitioned to videography when he realized the wonder and understanding the medium could convey.

So I gave up my Hasselblads, trading the sheer beauty of imagery for the much more powerful storytelling tools that came with the emerging field of video — specifically the ability to take the audience with you to experience the mission.”
From Space Frogs to the Eagle NebulaIn the 1980s and ’90s, Sisler worked as a producer on a wide range of projects, translating complex research into short documentaries and educational broadcasts.
“We were helping people see things that had never been seen before, and showing them relationships that they never knew existed,” he said.
In one of his favorite early assignments, Sisler worked with astronaut Mae Jemison for a video project on space frogs. Jemison was studying how frog embryos develop in microgravity on the space shuttle. Sisler also had a hand in early virtual reality systems, producing one of the first videos depicting how VR could work.

“They were shifting it from just mission-oriented content to a television news feed, exploring ideas to align with national news interests,” he said.
In one of his pilot stories, he produced a video and story news package about the Hubble Space Telescope’s observations of the Eagle Nebula.
“They handed me a 16-by-20-inch print of the Eagle Nebula right after Hubble imaged it,” he said. His team used a robotic camera to pan around the image while narration explained what viewers were seeing. “We wondered if we put that little microcosm of a story into a news feed, would anybody use it? And it ended up being used thousands and thousands of times, validating the NASA TV model with a bona fide science story and giving me a glimpse of the exciting stuff I could do.”
While at NASA Headquarters, Sisler also negotiated an IMAX agreement that led to new 3D films (including ones Sisler worked on, like the 1997 “Mission to Mir” and 2002 “Space Station 3D”). After a few years, he moved on to NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in 1997 as an executive producer. Goddard’s communications team was small and had little experience in visual storytelling, so he joined the team to nurture its growth.
Sisler stands alongside Office of Communications collaborators Laura Betz and Thaddeus Cesari at the immersive “Beyond the Light” exhibit of James Webb Space Telescope imagery at ARTECHOUSE in Washington, D.C.Credit: Courtesy of Wade Sisler Science for the SensesIn the late ’90s, Wade teamed up with NASA’s Scientific Visualization Studio (based at NASA Goddard) and lead visualizer Horace Mitchell to explore a new frontier in science storytelling. While NASA was already known for its iconic space imagery, much of its data deals with invisible phenomena or abstract processes that aren’t inherently visual. By bringing together scientists, artists, and producers, Sisler helped transform data into visualizations and animations for broader audiences.
“We had to invent ways of visualizing the invisible so meaning was more easily conveyed,” he said. “The result was stories that were not just newsworthy—they were often stunningly beautiful and showed the connections and workings of the Earth and universe in ways we had never seen before.”
The team had a breakout hit in 1998 with an El Niño visualization, which helped drive public understanding of the phenomenon. Sisler also helped launch a NASA Goddard program to link scientific experts with news stations around the world.
“We wanted to put the authentic voices of scientists in the chair to convey their sense of awe while telling people scientifically why it matters,” he said. “Pairing their voices with great visualizations was an unbeatable combination and that became the fundamental way we tell science stories.”
Sisler’s storytelling journey evolved into increasingly ambitious creative partnerships that brought NASA science to new cultural spaces. With “Cosmic Cycles,” a collaboration with the National Philharmonic, Wade helped create a program that paired music from a live symphony with high-resolution NASA imagery, inviting viewers to experience the celestial scenery emotionally, not just intellectually.
Instead of the NASA Goddard team creating a video to go along with music, “The composer drew inspiration from video produced by Goddard,” Sisler said. “It’s one of the best examples of science and art in mutual orbit.”

Sisler linked artists with NASA scientists to turn cutting-edge astrophysics into a gallery-scale sensory experience. Most recently, Sisler championed a major documentary on Webb called “Cosmic Dawn.” The 1.5-hour film brings viewers on an unprecedented journey through Webb’s delicate assembly, rigorous testing, and triumphant launch.
Many of NASA’s flagship communication programs trace their roots to small teams that Sisler helped assemble and guide. He took a builder’s approach, rolling up his sleeves, testing ideas, and empowering others to scale them. From science storytelling and satellite media tours to the rise of NASA’s audio storytelling, Spanish-language content, Conceptual Image Laboratory animations, social media presence, and live broadcast programming, Sisler played a key role in turning bright ideas into enduring agency assets.
For each of these projects, Sisler worked behind the scenes as a creative force and a connector, bringing together filmmakers, animators, composers, scientists, engineers, astronauts, museum curators, data visualizers, and educators.
Lighting the WayDespite many accolades, Sisler said his proudest accomplishment is the success of the internship program he has led for NASA Goddard’s Office of Communications.
Sisler has served as a mentor for many interns over the years, including students like Talya Lerner, center, standing next to Ed Campion, then-Goddard news chief. Sisler has referred to his own career as “the internship that never ended” because he had so many opportunities to explore different areas of communications. Credit: NASA/Bill Hrybyk“The thing that stays with me most is seeing where our former interns have landed,” he said. Many now lead their own programs within NASA, shaping the next generation of science storytelling from inside the agency. Others have taken their skills beyond NASA, contributing to science and technology literacy through media, education, and public engagement. “It’s been a privilege to help launch so many of these careers. I’ve always believed that when you combine mentorship, meaningful work, and a little creative freedom, you create a ripple effect that lasts for decades.”
Sisler’s own NASA journey began with a Pathways internship at NASA Ames while he was studying journalism at Baylor University in Texas. His work there drew him into visual storytelling, which led him to pursue photography, video, and science photography at the Rochester Institute of Technology in New York. As he alternated semesters between school and NASA Ames, he refined both his interests and his skills.
Sisler’s goal as an internship program coordinator was to help give the next generation of science communicators the same opportunity. He developed a communication “boot camp” to help interns develop their storytelling chops in many areas and figure out which were their favorites.
“All the interesting stuff happens at the intersections of people’s passions,” he said. “The best, most powerful thing I think I’ve done in my time at NASA is to help guide the next wave of science communicators. Seeing their success is the gift that keeps on giving.”

Curiosity Blog, Sols 4622-4623: Kicking Off (Earth) Year 14 With an Investigation of Veins NASA’s Mars rover Curiosity, using its Left Navigation Camera, caught the shadow of the rover’s mast looking ahead to new terrain as the mission started its 14th Earth year on Mars. Curiosity acquired this image on Aug. 6, 2025 — Sol 4621, or Martian day 4,621 of the Mars Science Laboratory mission — at 06:24:09 UTC. NASA/JPL-CaltechWritten by Abigail Fraeman, Deputy Project Scientist at NASA’s Jet Propulsion Laboratory
Earth planning date: Wednesday, Aug. 6, 2025.
Today was a very special day for Curiosity as the rover celebrated the start of a 14th year on Mars. Curiosity is currently exploring the mysterious boxwork formations. On Monday, the rover positioned itself at the side of one of the ridges, where the team had spotted tantalizing hints of a complex network of razor-thin veins that may give insight into what is holding the ridges up, compared to the surrounding hollows.
In this plan, the team will use the instruments on Curiosity’s arm and mast to investigate the geometry and composition of these veins to learn more about them. APXS and MAHLI will both observe “Repechón,” a loose block with dark-toned, mottled material exposed on top, as well as “Lago Poopó,” a bright, relatively clean vein network. MAHLI will also collect a side view of “Repechón.” ChemCam will use its laser to analyze two targets, “Vicguna,” a protruding vein edge with nodular texture, and “Ibare,” which has some exposed light-toned veins. Outside of the vein investigation, ChemCam’s telescopic RMI camera will observe layering in a nearby butte and the Mishe Mokwa feature, while Mastcam will take mosaics on “Cachiniba,” a broken block, “Yapacani,” the side of another large boxwork ridge, and “Llullaillaco,” a faraway feature that we imaged from a slightly different location in a previous plan. Additional environmental monitoring observations will round out the plan, followed by a straight-line drive to the east, to an area where several large boxwork ridges intersect that the team has been informally calling “the peace sign” because of its shape.
I usually get nostalgic around landing anniversaries, or “landiversaries,” and this year, I found myself looking back through pictures of landing night. One of my favorites shows me standing next to science team member Kirsten Siebach right after we received the first images from Curiosity. The two of us have the biggest, most excited grins on our faces. We were both graduate students at the time, and both of us were writing thesis chapters analyzing orbital data over regions we hoped to explore with Curiosity one day. I was studying a layer in Mount Sharp that contained hematite, and the team named this feature “Vera Rubin ridge” when Curiosity reached it in 2017. Kirsten, who is now a professor at Rice University, was focused on the boxwork structures, pondering how they formed and hypothesizing what they might tell us about the history of Martian habitability when we reached them.
Thirteen years later, I had another big grin on my face today, as I listened to Kirsten and our incredible science team members excitedly discussing Curiosity’s new images of these same boxwork structures. I was also filled with gratitude for the thousands of people it took to get us to this moment. It was the absolute best way to spend a landiversary.

NASA Supercomputers Take on Life Near Greenland’s Most Active Glacier
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Ocean currents swirl around North America (center left) and Greenland (upper right) in this data visualization created using NASA’s ECCO model. Advanced computing is helping oceanographers decipher hot spots of phytoplankton growth.NASA’s Scientific Visualization StudioAs Greenland’s ice retreats, it’s fueling tiny ocean organisms. To test why, scientists turned to a computer model out of JPL and MIT that’s been called a laboratory in itself.
Runoff from Greenland’s ice sheet is kicking nutrients up from the ocean depths and boosting phytoplankton growth, a new NASA-supported study has found. Reporting in Nature Communications: Earth & Environment, the scientists used state-of-the art-computing to simulate marine life and physics colliding in one turbulent fjord. Oceanographers are keen to understand what drives the tiny plantlike organisms, which take up carbon dioxide and power the world’s fisheries.
Greenland’s mile-thick ice sheet is shedding some 293 billion tons (266 billion metric tons) of ice per year. During peak summer melt, more than 300,000 gallons (1,200 cubic meters) of fresh water drain into the sea every second from beneath Jakobshavn Glacier, also known as Sermeq Kujalleq,the most active glacier on the ice sheet. The waters meet and tumble hundreds of feet below the surface.
Teal-colored phytoplankton bloom off the Greenland coast in this satellite image captured in June 2024 by NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission.NASAThe meltwater plume is fresh and more buoyant than the surrounding saltwater. As it rises, scientists have hypothesized, it may be delivering nutrients like iron and nitrate — a key ingredient in fertilizer — to phytoplankton floating at the surface.
Researchers track these microscopic organisms because, though smaller by far than a pinhead, they’re titans of the ocean food web. Inhabiting every ocean from the tropics to the polar regions, they nourish krill and other grazers that, in turn, support larger animals, including fish and whales.
Previous work using NASA satellite data found that the rate of phytoplankton growth in Arctic waters surged 57% between 1998 and 2018 alone. An infusion of nitrate from the depths would be especially pivotal to Greenland’s phytoplankton in summer, after most nutrients been consumed by prior spring blooms. But the hypothesis has been hard to test along the coast, where the remote terrain and icebergs as big as city blocks complicate long-term observations.
“We were faced with this classic problem of trying to understand a system that is so remote and buried beneath ice,” said Dustin Carroll, an oceanographer at San José State University who is also affiliated with NASA’s Jet Propulsion Laboratory in Southern California. “We needed a gem of a computer model to help.”
Sea of DataTo re-create what was happening in the waters around Greenland’s most active glacier, the team harnessed a model of the ocean developed at JPL and the Massachusetts Institute of Technology in Cambridge. The model ingests nearly all available ocean measurements collected by sea- and satellite-based instruments over the past three decades. That amounts to billions of data points, from water temperature and salinity to pressure at the seafloor. The model is called Estimating the Circulation and Climate of the Ocean-Darwin (ECCO-Darwin for short).
Simulating “biology, chemistry, and physics coming together” in even one pocket along Greenland’s 27,000 miles (43,000 kilometers) of coastline is a massive math problem, noted lead author Michael Wood, a computational oceanographer at San José State University. To break it down, he said the team built a “model within a model within a model” to zoom in on the details of the fjord at the foot of the glacier.
Using supercomputers at NASA’s Ames Research Center in Silicon Valley, they calculated that deepwater nutrients buoyed upward by glacial runoff would be sufficient to boost summertime phytoplankton growth by 15 to 40% in the study area.
More Changes in StoreCould increased phytoplankton be a boon for Greenland’s marine animals and fisheries? Carroll said that untangling impacts to the ecosystem will take time. Melt on the Greenland ice sheet is projected to accelerate in coming decades, affecting everything from sea level and land vegetation to the saltiness of coastal waters.
“We reconstructed what’s happening in one key system, but there’s more than 250 such glaciers around Greenland,” Carroll said. He noted that the team plans to extend their simulations to the whole Greenland coast and beyond.
Some changes appear to be impacting the carbon cycle both positively and negatively: The team calculated how runoff from the glacier alters the temperature and chemistry of seawater in the fjord, making it less able to dissolve carbon dioxide. That loss is canceled out, however, by the bigger blooms of phytoplankton taking up more carbon dioxide from the air as they photosynthesize.
Wood added: “We didn’t build these tools for one specific application. Our approach is applicable to any region, from the Texas Gulf to Alaska. Like a Swiss Army knife, we can apply it to lots of different scenarios.”

NASA’s Perseverance Rover Captures Mars Vista As Clear As Day
‘Float rocks,’ sand ripples, and vast distances are among the sights to see in the latest high-resolution panorama by the six-wheeled scientist.
The imaging team of NASA’s Perseverance Mars rover took advantage of clear skies on the Red Planet to capture one of the sharpest panoramas of its mission so far. Visible in the mosaic, which was stitched together from 96 images taken at a location the science team calls “Falbreen,” are a rock that appears to lie on top of a sand ripple, a boundary line between two geologic units, and hills as distant as 40 miles (65 kilometers) away. The enhanced-color version shows the Martian sky to be remarkably clear and deceptively blue, while in the natural-color version, it’s reddish.
“Our bold push for human space exploration will send astronauts back to the Moon,” said Sean Duffy, acting NASA administrator. “Stunning vistas like that of Falbreen, captured by our Perseverance rover, are just a glimpse of what we’ll soon witness with our own eyes. NASA’s groundbreaking missions, starting with Artemis, will propel our unstoppable journey to take human space exploration to the Martian surface. NASA is continuing to get bolder and stronger.”
The rover’s Mastcam-Z instrument captured the images on May 26, 2025, the 1,516th Martian day, or sol, of Perseverance’s mission, which began in February 2021 on the floor of Jezero Crater. Perseverance reached the top of the crater rim late last year.
“The relatively dust-free skies provide a clear view of the surrounding terrain,” said Jim Bell, Mastcam-Z’s principal investigator at Arizona State University in Tempe. “And in this particular mosaic, we have enhanced the color contrast, which accentuates the differences in the terrain and sky.”
Buoyant BoulderOne detail that caught the science team’s attention is a large rock that appears to sit atop a dark, crescent-shaped sand ripple to the right of the mosaic’s center, about 14 feet (4.4 meters) from the rover. Geologists call this type of rock a “float rock” because it was more than likely formed someplace else and transported to its current location. Whether this one arrived by a landslide, water, or wind is unknown, but the science team suspects it got here before the sand ripple formed.
The bright white circle just left of center and near the bottom of the image is an abrasion patch. This is the 43rd rock Perseverance has abraded since it landed on Mars. Two inches (5 centimeters) wide, the shallow patch is made with the rover’s drill and enables the science team to see what’s beneath the weathered, dusty surface of a rock before deciding to drill a core sample that would be stored in one of the mission’s titanium sample tubes.
The rover made this abrasion on May 22 and performed proximity science (a detailed analysis of Martian rocks and soil) with its arm-mounted instruments two days later. The science team wanted to learn about Falbreen because it’s situated within what may be some of the oldest terrain Perseverance has ever explored — perhaps even older than Jezero Crater.
Tracks from the rover’s journey to the location can be seen toward the mosaic’s right edge. About 300 feet (90 meters) away, they veer to the left, disappearing from sight at a previous geologic stop the science team calls “Kenmore.”
A little more than halfway up the mosaic, sweeping from one edge to the other, is the transition from lighter-toned to darker-toned rocks. This is the boundary line, or contact, between two geologic units. The flat, lighter-colored rocks nearer to the rover are rich in the mineral olivine, while the darker rocks farther away are believed to be much older clay-bearing rocks.

NASA Astronaut Barry “Butch” Wilmore Retires
After 25 years at NASA, flying in four different spacecraft, accumulating 464 days in space, astronaut and test pilot Butch Wilmore has retired from NASA.
The Tennessee native earned a bachelor’s and a master’s degree in electrical engineering from Tennessee Technological University and a master’s degree in aviation systems from the University of Tennessee.
Wilmore is a decorated U.S. Navy captain who has flown numerous tactical aircraft operationally while deploying aboard four aircraft carriers during peacetime and combat operations. A graduate of the U.S. Naval Test Pilot School, he went on to serve as a test pilot before NASA selected him to become an astronaut in 2000.
“Butch’s commitment to NASA’s mission and dedication to human space exploration is truly exemplary,” said Steve Koerner, acting director of NASA’s Johnson Space Center in Houston. “His lasting legacy of fortitude will continue to impact and inspire the Johnson workforce, future explorers, and the nation for generations. On behalf of NASA’s Johnson Space Center, we thank Butch for his service.”
During his time at NASA, Wilmore completed three missions launching aboard the space shuttle Atlantis, Roscosmos Soyuz, and Boeing Starliner to the International Space Station. Wilmore also returned to Earth aboard a SpaceX Dragon spacecraft. Additionally, he conducted five spacewalks, totaling 32 hours outside the orbital laboratory.
“Throughout his career, Butch has exemplified the technical excellence of what is required of an astronaut. His mastery of complex systems, coupled with his adaptability and steadfast commitment to NASA’s mission, has inspired us all,” said Joe Acaba, chief of the Astronaut Office at NASA Johnson. “As he steps into this new chapter, that same dedication will no doubt continue to show in whatever he decides to do next.”
Most recently, Wilmore launched aboard Boeing’s Starliner spacecraft on June 5, 2024, for its first crewed flight test mission, arriving at the space station the following day. While aboard the station, Wilmore completed numerous tasks, including a spacewalk to help remove a radio frequency group antenna assembly from the station’s truss and collected samples and surface material for analysis from the Destiny laboratory and the Quest airlock.
“From my earliest days, I have been captivated by the marvels of creation, looking upward with an insatiable curiosity. This curiosity propelled me into the skies, and eventually to space, where the magnificence of the cosmos mirrored the glory of its creator in ways words can scarcely convey,” said Wilmore. “Even as I ventured beyond Earth’s limits, I remained attuned to the beauty and significance of the world below, recognizing the same intricate design evident among the stars is also woven into the fabric of life at home.”

Curiosity Looks Back Toward Its Landing Site
NASA’s Curiosity rover captured a view of its tracks on July 26, 2025. The robotic scientist is now exploring a region of lower Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain. The pale peak of the mountain can be seen at top right; the rim of Gale Crater, within which the mountain sits, is on the horizon at top left. Curiosity touched down on the crater floor 13 years ago.
Recently, the rover rolled into a region filled with boxwork formations. Studying these formations could reveal whether microbial life could have survived in the Martian subsurface eons ago, extending the period of habitability farther into when the planet was drying out.

Mississippi Attorney Serves NASA and the Nation
Before Nathan Jermyn could dig into the legal frameworks at NASA, he had to answer a different call.
Jermyn participated in a one-day orientation in the summer of 2023 to begin work as an attorney-advisor supporting NASA’s Stennis Space Center and the NASA Shared Services Center near Bay St. Louis, Mississippi.
However, the Biloxi, Mississippi, native shipped out just a week later with the Mississippi Army National Guard to provide military legal counsel for nearly six months in support of Operation Spartan Shield and Operation Inherent Resolve.
The decorated military veteran returned to NASA in January 2024 to fully immerse himself as a member of the contract and procurement practice group for the NASA Office of the General Counsel.
“Even though I have been working here for two years, sometimes it does not feel real,” Jermyn said.
As a member of the contract and procurement law team, Jermyn assists with contract- and procurement-related topics for NASA Stennis and the NASA Shared Services Center to ensure taxpayer funds are used responsibly.
He also is a member of NASA’s Freedom of Information Act (FOIA) team and provides legal reviews and advice for FOIA requests as the agency creates a cohesive and effective knowledge-sharing environment.
The most interesting thing about his work is seeing how the big picture comes together, how each small detail and decision adds up to something more meaningful.
“Our office is a small piece, and it is amazing to see how our efforts intertwine with NASA Stennis and the NASA Shared Services Center operations and NASA,” he said. “It is also amazing the lengths everyone will go to help each other accomplish the mission.”
Before joining NASA, Jermyn graduated from The University of Southern Mississippi with a bachelor’s degree in business administration and a law degree from Mississippi College School of Law.
The Gulfport, Mississippi, resident initially practiced criminal law. Jermyn credits the team he works with at NASA for helping him navigate the complexities of government contract law.
“Having a team that supports you and teaches you every day really expedites the learning process,” he said. “Our team puts a heavy emphasis on learning, development, and teamwork.”
Jermyn is most excited to see how NASA continues to explore the universe moving forward, which includes the Artemis campaign of exploring the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars. Artemis II is scheduled for 2026.
“I wholeheartedly believe humanity is destined for the stars and NASA is in prime position to lead that charge,” he said.
