NASA will host a media teleconference at 11 a.m. EDT Wednesday, Sept. 10, to discuss the analysis of a rock sampled by the agency’s Perseverance Mars rover last year, which is the subject of a forthcoming science paper.
The sample, called “Sapphire Canyon,” was collected in July 2024 from a set of rocky outcrops on the edges of Neretva Vallis, a river valley carved by water rushing into Jezero Crater long ago.
Audio and visuals of the call will stream on the agency’s website at:
Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington
Lindsay Hays, Senior Scientist for Mars Exploration, Planetary Science Division, NASA Headquarters
Katie Stack Morgan, Perseverance Project Scientist, NASA’s Jet Propulsion Laboratory in Southern California
Joel Hurowitz, planetary scientist, Stony Brook University, New York
To ask questions by phone, members of the media must RSVP no later than two hours before the start of the event to: rexana.v.vizza@jpl.nasa.gov. NASA’s media accreditation policy is available online.
Since landing in the Red Planet’s Jezero Crater in February 2021, Perseverance has collected 30 samples. The rover still has six empty sample tubes to fill, and it continues to collect detailed information about geologic targets that it hasn’t sampled by using its abrasion tool. Among the rover’s science instruments is a weather station that provides environmental information for future human missions, as well as swatches of spacesuit material so that NASA can study how it fares on Mars.
Managed for NASA by Caltech, JPL built and manages operations of the Perseverance rover on behalf of the agency’s Science Mission Directorate as part of NASA’s Mars Exploration Program portfolio.

Rubio was selected as a NASA astronaut in 2017. He trained as a flight engineer and member of the Expedition 68 crew. Rubio, along with cosmonauts Sergey Prokopyev and Dmitry Petelin of Roscosmos, launched Sept. 21, 2022, on the Soyuz MS-22 spacecraft from the Baikonur Cosmodrome in Kazakhstan to the space station.
While aboard the orbital laboratory, Rubio and his fellow crew members conducted dozens of scientific investigations and technology demonstrations, including growing tomato plants to study hydroponic and aeroponic techniques, participating in crew health experiments, and studying how materials react in microgravity. Research like this and other activity on the orbital outpost will inform long-duration missions like Artemis and future human expeditions to Mars.
Rubio spent 371 days in space, surpassing NASA’s single spaceflight record for continuous days in space made by astronaut Mark Vande Hei. Rubio and his crewmates landed in Kazakhstan on Sept. 27, 2023. Rubio’s mission is the longest single spaceflight by a U.S. astronaut in history.

Scientists are in the midst of observing the exoplanet TRAPPIST-1 e with NASA’s James Webb Space Telescope. Careful analysis of the results so far presents several potential scenarios for what the planet’s atmosphere and surface may be like, as NASA science missions lay key groundwork to answer the question, “are we alone in the universe?”
“Webb’s infrared instruments are giving us more detail than we’ve ever had access to before, and the initial four observations we’ve been able to make of planet e are showing us what we will have to work with when the rest of the information comes in,” said Néstor Espinoza of the Space Telescope Science Institute in Baltimore, Maryland, a principal investigator on the research team. Two scientificpapers detailing the team’s initial results are published in the Astrophysical Journal Letters.

This artist’s concept shows the volatile red dwarf star TRAPPIST-1 and its four most closely orbiting planets, all of which have been observed by NASA’s James Webb Space Telescope. Webb has found no definitive signs of an atmosphere around any of these worlds yet.

Of the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, planet e is of particular interest because it orbits the star at a distance where water on the surface is theoretically possible — not too hot, not too cold — but only if the planet has an atmosphere. That’s where Webb comes in. Researchers aimed the telescope’s powerful NIRSpec (Near-Infrared Spectrograph) instrument at the system as planet e transited, or passed in front of, its star. Starlight passing through the planet’s atmosphere, if there is one, will be partially absorbed, and the corresponding dips in the light spectrum that reaches Webb will tell astronomers what chemicals are found there. With each additional transit, the atmospheric contents become clearer as more data is collected.
Primary atmosphere unlikely
Though multiple possibilities remain open for planet e because only four transits have been analyzed so far, the researchers feel confident that the planet does not still have its primary, or original, atmosphere. TRAPPIST-1 is a very active star, with frequent flares, so it is not surprising to researchers that any hydrogen-helium atmosphere with which the planet may have formed would have been stripped off by stellar radiation. However many planets, including Earth, build up a heavier secondary atmosphere after losing their primary atmosphere. It is possible that planet e was never able to do this and does not have a secondary atmosphere. Yet researchers say there is an equal chance there is an atmosphere, and the team developed novel approaches to working with Webb’s data to determine planet e’s potential atmospheres and surface environments.
World of (fewer) possibilities
The researchers say it is unlikely that the atmosphere of TRAPPIST-1 e is dominated by carbon dioxide, analogous to the thick atmosphere of Venus and the thin atmosphere of Mars. However, the researchers also are careful to note that there are no direct parallels with our solar system.
“TRAPPIST-1 is a very different star from our Sun, and so the planetary system around it is also very different, which challenges both our observational and theoretical assumptions,” said team member Nikole Lewis, an associate professor of astronomy at Cornell University.
If there is liquid water on TRAPPIST-1 e, the researchers say it would be accompanied by a greenhouse effect, in which various gases, particularly carbon dioxide, keep the atmosphere stable and the planet warm.
“A little greenhouse effect goes a long way,” said Lewis, and the measurements do not rule out adequate carbon dioxide to sustain some water on the surface. According to the team’s analysis, the water could take the form of a global ocean, or cover a smaller area of the planet where the star is at perpetual noon, surrounded by ice. This would be possible because, due to the TRAPPIST-1 planets’ sizes and close orbits to their star, it is thought that they all are tidally locked, with one side always facing the star and one side always in darkness.

Innovative new method
Espinoza and co-principal investigator Natalie Allen of Johns Hopkins University are leading a team that is currently making 15 additional observations of planet e, with an innovative twist. The scientists are timing the observations so that Webb catches both planets b and e transiting the star one right after the other. After previous Webb observations of planet b, the planet orbiting closest to TRAPPIST-1, scientists are fairly confident it is a bare rock without an atmosphere. This means that signals detected during planet b’s transit can be attributed to the star only, and because planet e transits at nearly the same time, there will be less complication from the star’s variability. Scientists plan to compare the data from both planets, and any indications of chemicals that show up only in planet e’s spectrum can be attributed to its atmosphere.
“We are really still in the early stages of learning what kind of amazing science we can do with Webb. It’s incredible to measure the details of starlight around Earth-sized planets 40 light-years away and learn what it might be like there, if life could be possible there,” said Ana Glidden, a post-doctoral researcher at Massachusetts Institute of Technology’s Kavli Institute for Astrophysics and Space Research, who led the research on possible atmospheres for planet e. “We’re in a new age of exploration that’s very exciting to be a part of,” she said.
The four transits of TRAPPIST-1 e analyzed in the new papers published today were collected by the JWST Telescope Scientist Team’s DREAMS (Deep Reconnaissance of Exoplanet Atmospheres using Multi-instrument Spectroscopy) collaboration.
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).

As college students across the country embark upon the academic year, NASA is giving them something else to look forward to – the agency’s 2026 Lunabotics Challenge. Teams interested in participating can submit their applications and supporting materials through NASA’s Stem Gateway portal beginning Monday, Sept. 8.
Key dates and challenge details are available in the 2026 Lunabotics Challenge Guidebook. Once all applications and supporting materials are received and evaluated, NASA will notify the selected teams to begin the challenge.
Student teams participating in this year’s challenge will create robots capable of building berms out of lunar regolith – the loose, fragmental material on the Moon’s surface. Structures like these will be important during lunar missions as blast protection during lunar landings and launches, shading for cryogenic propellant tank farms, radiation shielding around nuclear power plants, and other uses critical to future Moon missions.
“We are excited to continue the Lunabotics competition for universities as NASA develops new Moon to Mars technologies for the Artemis program,” said Robert Mueller, senior technologist at NASA, as well as co-founder and chief judge of the Lunabotics competition. “Excavating and moving regolith is a fundamental need to build infrastructure on the Moon and Mars and this competition creates 21st century skills in the future workforce.”
An in-person qualifying event will be held May 12-17, 2026, at the University of Central Florida’s Space Institute’s Exolith Lab in Orlando. From this round, the top 10 teams will be invited to bring their robots to the final competition on May 19-21, at the Kennedy Space Center Visitor Complex’s Artemis Arena in Florida, which has an area filled with a lunar regolith simulant. The team scoring the most points will receive the Lunabotics Grand Prize and participate in an exhibition-style event at NASA Kennedy.
By encouraging innovative construction techniques and assessing student designs and data the same way it does its own prototypes, NASA casts a wider net to find innovative solutions to challenges inherent in future Artemis missions, like developing future lunar excavators, in-situ resource utilization capabilities, and living on the Moon or Mars. With its multidisciplinary approach, Lunabotics also serves as a workforce pipeline, with teams gaining valuable hands-on experience in computer coding, engineering, manufacturing, fabricating, and other crucial skills, while also receiving technical expertise in space technology development.
NASA’s Lunabotics Challenge, held annually since 2010, is one of several Artemis Student Challenges. The two-semester competition provides U.S. college and technical school teams an opportunity to design, build, and operate a prototype lunar robot using NASA systems engineering processes. Competitions help NASA get innovative design and operational data, reduce risks, and cultivate new ideas needed to return to the Moon under the Artemis campaign to prepare for human exploration of Mars.
Jeni Morrison Continues a Family Legacy of Service at NASA
A child of the Space Shuttle Program, Jeni Morrison grew up walking the grounds of NASA’s Johnson Space Center in Houston with her parents and listening to family stories about human spaceflight.
Now, with more than 15 years at NASA, Morrison serves as one of Johnson’s Environmental Programs managers. She ensures the center complies with laws that protect its resources by overseeing regulatory compliance for cultural and natural resources, stormwater and drinking water programs, and the National Environmental Policy Act. She also safeguards Johnson’s historic legacy as Johnson’s Cultural Resources manager.

“I make sure our actions comply with the National Historic Preservation act, since the center is considered a historic district with two National Historic Landmarks onsite,” Morrison said. “I make sure we respect and document Johnson’s heritage while paving the way for new efforts and mission objectives.”
Morrison takes pride in finding solutions that increase efficiency while protecting resources. One example was a project with Johnson’s Geographic Information System team to create an interactive material and chemical spill plan map. The new system helps responders quickly trace spill paths above and underground to deploy resources faster, reducing cleanup costs and minimizing environmental impacts.
“Every improvement we make not only saves time and resources, but strengthens our ability to support NASA’s mission,” she said.
By the very nature of our work, NASA makes history all the time. That history is important for all people, both to remember the sacrifices and accomplishments of so many, but also to ensure we don’t repeat mistakes as we strive for even bolder achievements.

For Morrison, success often comes down to teamwork. She has learned to adapt her style to colleagues’ needs to strengthen collaboration.
“By making the effort to accommodate others’ communication styles and learn from different perspectives, we create better, more efficient work,” she said. “Thankfully, so many people here at NASA are willing to teach and to share their experiences.”
Her message to the Artemis Generation is simple: Always keep learning!
“You never know when a side conversation could give you an answer to a problem you are facing down the line,” she said. “You must be willing to ask questions and learn something new to find those connections.”

The team tested biobased metalworking coolants and identified a product that outperformed petroleum-based options, meeting flight hardware specifications while reducing waste disposal costs and labor hours.
Even as a young child visiting NASA Johnson, I could feel the sense of adventure, accomplishment, and the drive to reach new heights of human capability. I realize that those experiences gave me a fascination with learning and an inherent need to find ways to do things better.

Her passion for learning and discovery connects to a family tradition at NASA. Her grandfather contributed to multiple Apollo missions, including helping solve the oxygen tank malfunction on Apollo 13. Her mother worked at the center transcribing astronaut recordings and writing proposals, and her father flew experiments aboard the space shuttle and International Space Station. Morrison’s sister and extended family also worked at Johnson.
Now her son is growing up on the center grounds while attending the JSC Child Care Center. “As the fourth generation to be at Johnson, he is already talking about how he loves science and can’t wait to do his own experiments,” she said.
For Morrison, carrying that family legacy forward through environmental stewardship is a privilege. “Being able to contribute to NASA’s mission through environmental compliance feels like the best of both worlds for me,” Morrison said. “It combines my love of science and NASA with my drive to find more efficient ways to operate while protecting this incredible site and everything it represents.”
