Moon and Flag at NASA Michoud
Just after sunrise, the waning gibbous moon sets just behind a waving United States flag on March 19, 2025, in this image from NASA’s Michoud Assembly Facility in New Orleans. The waning gibbous moon phase comes after the full moon. As the Moon begins its journey back toward the Sun, the opposite side of the Moon now reflects the Moon’s light. The lighted side appears to shrink, but the Moon’s orbit is simply carrying it out of view from our perspective. The Moon also rises later and later each night.

Student Coders Bring Novel Approaches to NASA Challenge
On March 28, 80 college students filed into Colorado State University’s (CSU) Nancy Richardson Design Center to receive pizza and a challenge: design an intelligent system capable of traversing rugged terrain to provide aid in emergency scenarios.
They had 24 hours to complete this mission.
Co-led by CSU, the United States Department of Agriculture (USDA) Forest Service, and NASA, the Spring 2025 CSU Hackathon forged a symbiotic relationship between federal agencies looking for novel AI solutions and innovative students hungry for a challenge.
“One of the goals of the Career Center is to create opportunities for relationship building,” said Mika Dalton, CSU’s career center employer relations coordinator. “Events like these really help students connect with industry and identify different career pathways to expand their understanding of where their education could lead them after graduation.”
In teams of four, students chose between two technical prompts grounded in real-world data. The USDA Forest Service posed the “Uncharted Challenge,” asking teams to develop an autonomous mapping system for uncharted National Forest System roads using high-resolution satellite imagery. In the “Rover Challenge” posed by NASA, students were asked to design an algorithm that could autonomously guide a rover across rough terrain to reach an injured firefighter.
Over the next 24 hours, students analyzed lidar and satellite imagery, built algorithms, and tested their models in SageMaker, a development environment hosted by Amazon Web Services (AWS). As they collaborated on their solutions, students also helped NASA evaluate SageMaker’s potential for agency adoption.
The students’ work delivered tangible value to both agencies, demonstrating novel approaches to real operational challenges like wildfire response, terrain mapping, and emergency search and rescue.
The students did an incredible job showing how AI can solve tough problems, from navigating the Moon to handling emergencies, all in line with NASA’s mission.Martin Garcia
NASA’s artificial intelligence and innovation lead
For the USDA, accurate and efficient trail maps can support fire crews and forest managers; for NASA, more advanced terrain navigation systems enhance efforts in AI-assisted robotics, including lunar rovers tasked with reaching astronauts or delivering supplies in critical missions. “The students’ consideration for energy efficient lunar vehicle traversal would benefit the agency’s mission to implement extended scientific and engineering missions on the lunar surface,” said NASA data scientist Andrew Wilder.
Winning teams received recognition for Best Overall Project, Ingenuity, Simplicity, and Tenacity. Prizes included letters of recommendation from agency leaders and future opportunities to present their work to NASA and Forest Service staff.
“I had a great team, and we were able to work through several setbacks with clear communication. I also got to meet professionals from NASA, USDA, Forest Service, and AWS. These were great opportunities and so I learned a lot of networking and interviewing from them,” said one participating CSU student.
Ultimately, 98% of post-event student survey respondents indicated a strong enthusiasm to share this event with other students. Along with the endorsement, students shared that it was a great way to learn skills, network, and try something new. Many respondents, while strongly recommending the event, emphasized that the event was very challenging, intense, and a place to apply classroom knowledge.
The hackathon demonstrated what’s possible when creativity, passion, and partnership align. For NASA’s Chief AI Officer (CAIO), it offered a clear proof of concept: a low-cost, high-impact model for advancing AI adoption by connecting real-world challenges with emerging talent. Beyond the technical outputs, NASA gained testable solutions, valuable insights into rapid prototyping, and deeper relationships with federal, academic, and industry partners. The hackathon also provided a repeatable framework for future events with other institutions.
By bringing together mission teams, partners, and student innovators—and fueling them with pizza and friendly competition—NASA is accelerating innovation in bold, creative ways.

Hubble Spies a Spiral So Inclined This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 3511. ESA/Hubble & NASA, D. ThilkerThe stately and inclined spiral galaxy NGC 3511 is the subject of this NASA/ESA Hubble Space Telescope image. The galaxy is located 43 million light-years away in the constellation Crater (The Cup). From Hubble’s vantage point in orbit around Earth, NGC 3511 is tilted by about 70 degrees, intermediate between face-on galaxies that display the full disk of the spiral and its arms, and edge-on galaxies that offer a side view, revealing only their dense, flattened disks.
Astronomers are studying NGC 3511 as part of a survey of the star formation cycle in nearby galaxies. For this observing program, Hubble will record the appearance of 55 local galaxies using five filters that allow in different wavelengths, or colors, of light.
One of these filters allows only a specific wavelength of red light to pass through. Giant clouds of hydrogen gas glow in this red color when energized by ultraviolet light from hot young stars. As this image shows, NGC 3511 contains many of these bright red gas clouds, some of which are curled around clusters of brilliant blue stars. Hubble will help astronomers catalog and measure the ages of these stars, which are typically less than a few million years old and several times more massive than the Sun.

NASA Supports Artemis Accords Signatories Advancing Exploration
The United States participated in an international Artemis Accords workshop May 21-22 to advance the safe and responsible exploration of the Moon, Mars, and beyond. Hosted by the United Arab Emirates (UAE), which was represented by the UAE Space Agency, the workshop took place at the Abu Dhabi National Exhibition Centre.
The Artemis Accords are a set of non-binding principles signed by nations for a peaceful and prosperous future in space for all of humanity to enjoy. In October 2020, under the first Trump administration, the accords were created, and since then, 54 countries have joined with the United States in committing to transparent and responsible behavior in space.
“Following President Trump’s visit to the Middle East, the United States built upon the successful trip through engagement with a global coalition of nations to further implement the accords – practical guidelines for ensuring transparency, peaceful cooperation, and shared prosperity in space exploration,” said acting NASA Administrator Janet Petro. “These accords represent a vital step toward uniting the world in the pursuit of exploration and scientific discovery beyond Earth. NASA is proud to lead in the overall accords effort, advancing the principles as we push the boundaries of human presence in space – for the benefit of all.”
Participants from 30 countries joined the discussions and a tabletop exercise centered on defining challenges for operating in a complex environment.
As the Artemis Accords workshop concluded Thursday, participants reaffirmed their commitment to upholding the principles outlined in the accords and to continue identifying best practices and guidelines for safe and sustainable exploration. The first workshop was hosted by Poland in 2023, followed by Canada in 2024.
Artemis Accords signatories have committed to sharing information about their activities to the United Nations of Committee on the Peaceful Uses of Outer Space and other appropriate channels. Transparency and communication are key to peaceful exploration.
The Artemis Accords signatories will gather for face-to-face discussions on the margins of the International Astronautical Congress in late September, where workshop recommendations and outcomes will be presented to the Artemis Accords principals. NASA anticipates additional countries will sign in the coming weeks and months.
The Artemis Accords are grounded in the Outer Space Treaty and other agreements, including the Registration Convention and the Rescue and Return Agreement, as well as best practices for responsible behavior that NASA and its partners have supported, including the public release of scientific data.

Sols 4547-4548: Taking in the View After a Long Drive NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on May 21, 2025 — Sol 4546, or Martian day 4,546 of the Mars Science Laboratory mission — at 05:05:33 UTC. NASA/JPL-CaltechWritten by Alex Innanen, Atmospheric Scientist at York University
Earth planning date: Wednesday, May 21, 2025
Monday’s single-sol plan included a marathon 45-meter drive (about 148 feet), which put us in position for two full sols of imaging. This means both sols have what we call “targeted” science blocks, in which we have images of the workspace down from the last plan and can carefully choose what we want to take a closer look at. This always means a lot of good discussion amongst the geology and mineralogy theme group (GEO) about what deserves this closer look. As an outsider on the environmental theme group (ENV), I don’t always grasp the complexities of these discussions, but it’s always interesting to see what GEO is up to and to learn new things about the geology of Mount Sharp.
GEO ended up picking “Big Bear Lake” as our contact science target, which is getting its typical treatment from APXS and MAHLI, as well as a LIBS observation from ChemCam. Aside from that there was plenty of room for remote sensing. ChemCam is also taking a LIBS observation of “Volcan Mountains” and a long-distance mosaic of the Texoli butte. Mastcam is also taking mosaics of a nearby trough, as well as two depressions known as “Sulphur Spring,” a more distant boxwork structure, and the very distant Mishe Mokwa butte.
All of ENV’s activities are remote sensing, and we managed to squeeze in a few of those too. We have a couple dust monitoring observations, looking for dust devils and checking the amount of dust in the atmosphere. And since we’re still in the cloudy season we always try to make room for cloud observations. Today that meant a suraphorizon movie looking for clouds just above the horizon to the south, and a phase function sky survey, which captures clouds all around the rover, to try to understand how these clouds scatter sunlight.

GEO ended up picking “Big Bear Lake” as our contact science target, which is getting its typical treatment from APXS and MAHLI, as well as a LIBS observation from ChemCam. Aside from that there was plenty of room for remote sensing. ChemCam is also taking a LIBS observation of “Volcan Mountains” and a long-distance mosaic of the Texoli butte. Mastcam is also taking mosaics of a nearby trough, as well as two depressions known as “Sulphur Spring,” a more distant boxwork structure, and the very distant Mishe Mokwa butte.
All of ENV’s activities are remote sensing, and we managed to squeeze in a few of those too. We have a couple dust monitoring observations, looking for dust devils and checking the amount of dust in the atmosphere. And since we’re still in the cloudy season we always try to make room for cloud observations. Today that meant a suraphorizon movie looking for clouds just above the horizon to the south, and a phase function sky survey, which captures clouds all around the rover, to try to understand how these clouds scatter sunlight.

Percolating Clues: NASA Models New Way to Build Planetary Cores
5 min read
Percolating Clues: NASA Models New Way to Build Planetary Cores NASA’s Perseverance rover was traveling in the channel of an ancient river, Neretva Vallis, when it captured this view of an area of scientific interest nicknamed “Bright Angel” – the light-toned area in the distance at right. The area features light-toned rocky outcrops that may represent either ancient sediment that later filled the channel or possibly much older rock that was subsequently exposed by river erosion. NASA/JPL-CaltechA new NASA study reveals a surprising way planetary cores may have formed—one that could reshape how scientists understand the early evolution of rocky planets like Mars.
Conducted by a team of early-career scientists and long-time researchers across the Astromaterials Research and Exploration Science (ARES) Division at NASA’s Johnson Space Center in Houston, the study offers the first direct experimental and geochemical evidence that molten sulfide, rather than metal, could percolate through solid rock and form a core—even before a planet’s silicate mantle begins to melt.
For decades, scientists believed that forming a core required large-scale melting of a planetary body, followed by heavy metallic elements sinking to the center. This study introduces a new scenario—especially relevant for planets forming farther from the Sun, where sulfur and oxygen are more abundant than iron. In these volatile-rich environments, sulfur behaves like road salt on an icy street—it lowers the melting point by reacting with metallic iron to form iron-sulfide so that it may migrate and combine into a core. Until now, scientists didn’t know if sulfide could travel through solid rock under realistic planet formation conditions.

The study results gave researchers a way to directly observe this process using high-resolution 3D imagery—confirming long-standing models about how core formation can occur through percolation, in which dense liquid sulfide travels through microscopic cracks in solid rock.
“We could actually see in full 3D renderings how the sulfide melts were moving through the experimental sample, percolating in cracks between other minerals,” said Dr. Sam Crossley of the University of Arizona in Tucson, who led the project while a postdoctoral fellow with NASA Johnson’s ARES Division. “It confirmed our hypothesis—that in a planetary setting, these dense melts would migrate to the center of a body and form a core, even before the surrounding rock began to melt.”
Recreating planetary formation conditions in the lab required not only experimental precision but also close collaboration among early-career scientists across ARES to develop new ways of observing and analyzing the results. The high-temperature experiments were first conducted in the experimental petrology lab, after which the resulting samples—or “run products”—were brought to NASA Johnson’s X-ray computed tomography (XCT) lab for imaging.

These visualizations offered insight into the physical behavior of materials during early core formation without destroying the sample.
The 3D XCT visualizations initially confirmed that sulfide melts could percolate through solid rock under experimental conditions, but that alone could not confirm whether percolative core formation occurred over 4.5 billion years ago. For that, researchers turned to meteorites.
“We took the next step and searched for forensic chemical evidence of sulfide percolation in meteorites,” Crossley said. “By partially melting synthetic sulfides infused with trace platinum-group metals, we were able to reproduce the same unusual chemical patterns found in oxygen-rich meteorites—providing strong evidence that sulfide percolation occurred under those conditions in the early solar system.”
To understand the distribution of trace elements, study co-author Dr. Jake Setera, also of Amentum, developed a novel laser ablation technique to accurately measure platinum-group metals, which concentrate in sulfides and metals.
“Working on this project pushed us to be creative,” Setera said. “To confirm what the 3D visualizations were showing us, we needed to develop an appropriate laser ablation method that could trace the platinum group-elements in these complex experimental samples. It was exciting to see both data streams converge on the same story.”
When paired with Setera’s geochemical analysis, the data provided powerful, independent lines of evidence that molten sulfide had migrated and coalesced within a solid planetary interior. This dual confirmation marked the first direct demonstration of the process in a laboratory setting.

Mars in particular shows signs of early core formation—but the timeline has puzzled scientists for years. The new results suggest that Mars’ core may have formed at an earlier stage, thanks to its sulfur-rich composition—potentially without requiring the full-scale melting that Earth experienced. This could help explain longstanding puzzles in Mars’ geochemical timeline and early differentiation.
The results also raise new questions about how scientists date core formation events using radiogenic isotopes, such as hafnium and tungsten. If sulfur and oxygen are more abundant during a planet’s formation, certain elements may behave differently than expected—remaining in the mantle instead of the core and affecting the geochemical “clocks” used to estimate planetary timelines.
This research advances our understanding of how planetary interiors can form under different chemical conditions—offering new possibilities for interpreting the evolution of rocky bodies like Mars. By combining experimental petrology, geochemical analysis, and 3D imaging, the team demonstrated how collaborative, multi-method approaches can uncover processes that were once only theoretical.
Crossley led the research during his time as a McKay Postdoctoral Fellow—a program that recognizes outstanding early-career scientists within five years of earning their doctorate. Jointly offered by NASA’s ARES Division and the Lunar and Planetary Institute in Houston, the fellowship supports innovative research in astromaterials science, including the origin and evolution of planetary bodies across the solar system.
As NASA prepares for future missions to the Moon, Mars, and beyond, understanding how planetary interiors form is more important than ever. Studies like this one help scientists interpret remote data from spacecraft, analyze returned samples, and build better models of how our solar system came to be.
