NASA is kicking off the 2026 Student Launch challenge, looking for new student teams to design, build, and launch high-powered rockets with a scientific or engineering payload next April. 

The agency is seeking proposals until Monday, Sept. 22. Details about this year’s challenge are in the 2026 handbook, which outlines the requirements for middle school, high school, and college students to participate. After a competitive proposal selection process, selected teams must meet documentation milestones and undergo detailed reviews throughout the activity year. 

“These bright students rise to a nine-month challenge for Student Launch that tests their skills in engineering, design, and teamwork,” said Kevin McGhaw, director of NASA’s Office of STEM Engagement Southeast Region. “They are part of the Golden Age of explorers – the future scientists, engineers, and innovators who will lead us into the future of space exploration.”

Student Launch will culminate with on-site events starting on April 22, 2026. Final launches are scheduled for April 25, at Bragg Farms in Toney, Alabama, near NASA’s Marshall Space Flight Center in Huntsville, Alabama. 

Each year, NASA updates the university payload challenge to reflect current scientific and exploration missions. For the 2026 season, the payload challenge will take inspiration from the Artemis missions, which seek to explore the Moon for scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars. This year’s payload challenge tasks college and university teams with designing, building, and flying a habitat to safely house four STEMnauts – non-living objects representing astronauts – during extended missions. The habitat must include equipment capable of both collecting and testing soil samples to support agricultural research operations.

Nearly 1,000 students participated in the 2025 Student Launch competition – making up 71 teams from across the United States. Teams launched their rockets to an altitude between 4,000 and 6,000 feet, while attempting to make a successful landing and executing the payload mission.

 Former NASA Marshall Director Art Stephenson started Student Launch in 2000 as a student rocket competition at the center. Just two university teams competed in the inaugural challenge – Alabama A&M University and the University of Alabama in Huntsville. The challenge continues to soar with thousands of students participating in the STEM competition each year, and many going on to a career with NASA.

NASA Marshall’s Office of STEM Engagement hosts Student Launch to provide students with real-world experiences that encourage them to pursue degrees and careers in science, technology, engineering, and mathematics. Student Launch is one of several NASA Artemis Student Challenges – a variety of activities that expose students to the knowledge and technology required to achieve the goals of the agency’s Artemis campaign. 

In addition to NASA Office of STEM Engagement’s Next Generation STEM project, NASA Space Operations Mission Directorate, Northrop Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and, Bastion Technologies provide funding and leadership for the Student Launch competition.

Introduction

Landsat, a joint program of NASA and the U.S. Geological Survey (USGS), has been an invaluable tool for monitoring changes in Earth’s land surface for over 50 years. Researchers use instruments on Landsat satellites to monitor decades-long trends, including urbanization and agricultural expansion, as well as short-term dynamics, including water use and disaster recovery. However, scientists and land managers often encounter one critical limitation of this program: Landsat has a revisit time of eight days (with Landsat 8 and 9 operating), which is too long to capture events and disasters that occur on short timescales. Floods, for example, can quickly inundate a region, and cloud cover from storms can delay Landsat’s ability to get a clear observation on damage.

In 2015, the European Space Agency’s (ESA) Copernicus Sentinel-2A mission joined Landsat 7 and 8 in orbit. It was designed to collect comparable optical land data with the intention of leveraging Landsat’s archive. Two years later, ESA launched Sentinel-2B, a satellite identical to Sentinel-2A.

Led by a science team at NASA’s Goddard Space Flight Center (GSFC), the USGS, NASA, and ESA began to work on combining the capabilities of Sentinel-2 and Landsat satellites. This idea was the impetus behind Harmonized Landsat and Sentinel-2 (HLS) project, a NASA initiative that created a seamless product from the Operational Land Imager (OLI) and Multi-Spectral Instrument (MSI) aboard Landsat and Sentinel-2 satellites, respectively. HLS Version 2.0 (V2.0) is the most recent version of these data and had a global median repeat frequency of 1.6 days in 2022 by combining observations from Landsat 8 and 9 and Sentinel-2A and B. The recent addition of Sentinel-2C data will provide even more frequent observations. With near-global coverage and improved harmonization algorithms, HLS V2.0 paves the way for new applications and improved land monitoring systems – see Animation 1. HLS data are available for download on NASA Earthdata: HLSL30v2.0 and HLSS30v2.0. These data can also be accessed through Google Earth Engine: HLSL30v2.0 and HLSS30v2.0. 

The Dawn of HLS

The story of HLS begins before the launch of Sentinel-2A in 2015. Jeffrey Masek [GSFC], who was at that time project scientist for Landsat 8, led a group of researchers who wanted to find a way to harmonize Landsat data with other satellite data. Their aim was to create a “virtual constellation” similar to how weather satellites operate.

“HLS meets a need that people have been asking for for a long time,” said Masek.

What began as a research question with an experimental product evolved into an operational project with the involvement of the Satellite Needs Working Group (SNWG). SNWG is an interagency effort to develop solutions that address Earth observation needs of civilian federal agencies. Every two years, SNWG conducts a survey of federal agencies to see how their work could benefit from satellite data. The answers span the gamut of application areas, from water quality monitoring to disaster recovery to planning how best to protect and use natural resources. SNWG brings these ideas to NASA, USGS, and the National Oceanic and Atmospheric Administration (NOAA) – the three main U.S. government providers of satellite data. These agencies work together to create and implement solutions that serve those needs. NASA plays a critical role in every step of the SNWG process, including leading the assessment of survey responses from over 30 federal agencies, managing and supporting the implementation of identified solutions, and encouraging solution co-design with federal partners to maximize impact.

The HLS surface reflectance product was an outcome of the very first SNWG solution cycle in 2016. This product was expanded, following additional SNWG requests in 2020 and 2022. The 2020 cycle saw the creation of nine HLS-derived vegetation indices, and the 2022 cycle aimed for a six-hour latency product.

The U.S. Department of Agriculture (USDA) now uses HLS to map crop emergence at the field scale in the corn belt, allowing farmers to better plan their growing seasons. Ranchers in Colorado use the dataset to decide where to graze their cattle during periods of drought. HLS also informs the use and termination of cover crops in the Chesapeake Bay area. In 2024, the Federal Emergency Management Agency (FEMA) employed HLS to identify where to focus aid in the aftermath of Hurricane Helene.

A New and Improved HLS

In the July 2025 issue of Remote Sensing of Environment, a team of researchers outlined the HLS V2.0 surface reflectance dataset and algorithms. The team included seven NASA co-authors, members of the 2018–2023 Landsat Science Team, and ESA. The lead author, Junchang Ju [GSFC—Remote Sensing Scientist], has been the technical lead on HLS since its inception. Co-author Christopher Neigh [GSFC—Landsat 8/9 Project Scientist] is the principal investigator on the HLS project. V2.0, which was completed in Summer 2023, incorporates several major improvements over HLS V1.4, the most recent publicly available HLS product. The HLS production team at NASA’s Marshall Space Flight Center (MSFC), led by Madhu Sridhar [University of Alabama in Huntsville—Research Scientist], ensures consistent data access through close collaboration with ESA and the Land Processes Distributed Active Archive Center (LP DAAC). HLS V1.4 covered about 30% of the global land area, providing data on North America and other select locations. HLS V2.0 provides data at a spatial resolution of 30 m (98 ft) with near-global coverage from 2013 onward. The dataset includes all land masses except Antarctica. HLS V2.0 also has key algorithmic improvements in atmospheric correction, cloud masking, and bidirectional reflectance distribution function (BRDF) correction. Together, these algorithms “harmonize” the data, or ensure that the distinct Landsat and Sentinel-2 datasets can effectively be used interchangeably – see Animation 2.

HLS V2.0 in Action

The increased frequency of observations improved the ability of the scientific community to track disaster recovery, changes in phenology, agricultural intensification, rapid urban growth, logging, and deforestation. Researchers are already putting these advances to use.

The land disturbance product (DIST-ALERT) is a global land change monitoring system that uses HLS V2.0 data to track vegetation anomalies in near real-time – see Figure 1. DIST-ALERT captures agricultural expansion, urban growth, fire, flooding, logging, drought, landslides, and other forces of change to vegetation. Amy Pickens [University of Maryland, Department of Geographical Sciences—Assistant Research Professor] said that HLS is the perfect dataset for tracking disturbances because of the frequency of observations.

DIST-ALERT was created through Observational Products for End-Users from Remote Sensing Analysis (OPERA), a project at NASA/Jet Propulsion Laboratory (JPL). OPERA products respond to agency needs identified by the SNWG. In 2018, SNWG identified tracking surface disturbance as a key need. OPERA partnered with the Global Land Analysis and Discovery (GLAD) lab at University of Maryland to develop the change detection algorithm.

To track changes in vegetation, the DIST-ALERT system establishes a rolling baseline – meaning that for any given pixel, the vegetation cover is compared against vegetation cover from the same 31-day window in the previous three years. The primary algorithm detects any vegetation loss relative to the established baseline. A secondary algorithm flags any spectral anomaly (i.e., any change in reflectance) compared to that same baseline. This approach ensures that the algorithm catches non-vegetation change (e.g., new building or road projects in unvegetated areas). Used together, these algorithms can identify long-term changes in agricultural expansion, deforestation, and urbanization alongside short-term changes in crop harvest, drought, selective logging, and the impacts of disasters. On average, DIST-ALERT is made available on LP DAAC within six hours of when new HLS data is available. Currently, the dataset does not provide attribution to disturbances.

Disturbance alerts already exist in some ecosystems. Brazil’s National Institute for Space Research [Instituto Nacional de Pesquisas Espaciais (INPE)] runs two projects that detect deforestation in the Amazon: Programa de Cálculo do Desflorestamento da Amazônia (PRODES) and Sistema de Detecção de Desmatamento em Tempo Real (DETER). The GLAD lab created its own forest loss alerts – GLAD-L and GLAD-S2 – using Landsat and Sentinel-2 data respectively. Global Forest Watch integrates GLAD-L and GLAD-S2 data with Radar for Detecting Deforestation (RADD) observations – derived from synthetic aperture radar data from Copernicus Sentinel-1 – into an integrated deforestation alert.

The implementation of these alert systems, some of which have been around for decades, have been shown to impact deforestation rates in the tropics. For example, a 2021 study in Nature Climate Change found that deforestation alerts decreased the probability of deforestation in Central Africa by 18% relative to the average 2011–2016 levels.

DIST-ALERT is distinct from other alert systems in a few ways. First, it has global coverage. Second, the rolling baseline allows for tracking changes in seasonality and disturbances to dynamic ecosystems. When HLS V2.0 data are input to DIST-ALERT, the system is also better at identifying disturbances in cloudy ecosystems than other individual alert systems – because it is more likely to obtain clear observations. This also enables it to identify the start and end of the disturbance more precisely.

Pickens said that the DIST-ALERT team is already working with end-users who are implementing their data product. She has spoken to some who use the system to help logging companies prove that they are complying with regulations. The U.S. Census Bureau is also using DIST-ALERT to monitor fast-growing communities so that they can do targeted assessments in the interim between the larger decennial census.

Alongside DIST-ALERT, OPERA has also been developing the Dynamic Surface Water eXtent (DSWx) product suite, which employs HLS to track surface water (e.g., lakes, reservoirs, rivers, and floods) around the globe – see Figure 2. These new products represent the new applications made possible by the HLS interagency and international collaboration.

Conclusion

HLS is set to continue improving land monitoring efforts across the globe. Meanwhile, the HLS science team is working to improve the algorithms for a more seamless harmonization of Landsat 8 and 9 and Sentinel-2 data. They are also working to improve the cloud-masking algorithm, have recently released vegetation indices, and are working on developing a low-latency (six-hour) HLS surface reflectance product, all while incorporating user feedback.

Looking ahead, the launch of future Sentinel and Landsat satellites will further the development of HLS. The additional data and unique capabilities will continue to meet researchers’ need for more frequent, high-quality satellite observations of Earth’s land surface.

Lindy Garay always knew she wanted to develop software. She did not anticipate that her work would contribute to human spaceflight.

The electrical and software engineering degree Garay earned from the University of Texas at Austin paved the way for a 25-year career with NASA’s Johnson Space Center in Houston. Her first job out of college was developing software for the International Space Station Program’s original space station training facility simulator. “I had not always been interested in working in the space program, but I became enamored with being able to contribute to such an important mission,” she said.

Today, Garay serves as a training systems software architect and is the technical lead for training system external interfaces. That means she leads the team that helps connect training simulations from NASA’s external partners with simulations run by Johnson’s Mission Training Center (MTC) to support crew and flight controller training. The MTC currently provides training capabilities for the International Space Station Program, the Commercial Crew Program, and Artemis campaign components such as the Orion Program and the human landing system.

Garay said that not having an aerospace background was challenging at the beginning of her career, but she overcame that by leaning on teammates who had knowledge and experience in the field. “Every successful endeavor depends on having a solid team of dedicated people working toward one goal,” she said. “Success also depends on good communication, flexibility, and being willing to listen to different opinions,” she added.

Garay was recently named as a 2025 NASA Space Flight Awareness Program Honoree – one of the highest recognitions presented to the agency’s workforce. Recipients must have significantly contributed to the human spaceflight program to ensure flight safety and mission success. Garay’s commendation acknowledged her “sustained superior performance, dedication, and commitment to the Flight Operations Directorate’s goals” and her instrumental role in the success of several major training systems projects. In particular, she was recognized for contributions to the High-Level Architecture simulation framework, which is used to create realistic simulations of visiting vehicles’ arrival, docking, and departure from the space station.

Garay and 36 other agency honorees were celebrated during a special ceremony in Cocoa Beach, Florida, and had the opportunity to attend the launch of NASA’s SpaceX Crew-10 mission at NASA’s Kennedy Space Center. “That was quite an honor,” she said.

Outside of work, Garay may be found cheering on Houston’s sports teams. She enjoys traveling to watch the Texans and the Astros play.

Garay is also rooting for the Artemis Generation as NASA prepares to return to the Moon and journey on to Mars. She offered this advice: “Always remember the importance and the magnitude of the whole mission.”

NASA is down to 25 finalists for the Artemis II zero gravity indicator set to fly with the mission’s crew around the Moon and back next year.

Astronauts Reid Wiseman, Victor Glover, and Christina Koch of NASA, and CSA (Canadian Space Agency) astronaut Jeremy Hansen will soon select one of the finalist designs to join them inside the Orion spacecraft as their Moon mascot.

“The Artemis II zero gravity indicator will be special for the crew,” said Reid Wiseman, Artemis II commander. “In a spacecraft filled with complex hardware to keep the crew alive in deep space, the indicator is a friendly and useful way to highlight the human element that is so critical to our exploration of the universe. Our crew is excited about these designs from across the world and we are looking forward to bringing the winner along for the ride.”

A zero gravity indicator is a small plush item that typically rides with a crew to visually indicate when they are in space. For the first eight minutes after liftoff, the crew and their indicator nearby will still be pushed into their seats by gravity, and the force of the climb into space. When the main engines of the SLS (Space Launch System) rocket’s core stage cut off, gravity’s restraints are lifted, but the crew will still be strapped safely into their seats – their zero gravity indicator’s ability to float will provide proof that they’ve made it into space.

Artemis II will mark the first time that the public has had a hand in creating the crew’s mascot.

These designs – ideas spanning from Moon-related twists on Earthly creatures to creative visions of exploration and discovery – were selected from more than 2,600 submissions from over 50 countries, including from K-12 students. The finalists represent 10 countries including the United States, Canada, Colombia, Finland, France, Germany, Japan, Peru, Singapore, and Wales.

View the finalist designs:

In March, NASA announced it was seeking design ideas from global creators for a zero gravity indicator to fly aboard Artemis II, the first crewed mission under NASA’s Artemis campaign. Creators were asked to submit ideas representing the significance of Artemis, the mission, or exploration and discovery, and to meet specific size and materials requirements. Crowdsourcing company Freelancer facilitated the contest on NASA’s behalf though the NASA Tournament Lab, managed by the agency’s Space Technology Mission Directorate.

Once the crew has selected a final design, NASA’s Thermal Blanket Lab will fabricate it for flight. The indicator will be tethered inside Orion before launch.

The approximately 10-day mission is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.

Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars.

Asteroid Bennu, sampled by NASA’s OSIRIS-REx mission in 2020, is a mixture of dust that formed in our solar system, organic matter from interstellar space, and pre-solar system stardust. Its unique and varied contents were dramatically transformed over time by interactions with water and exposure to the harsh space environment.

These insights come from a trio of newly published papers based on the analysis of Bennu samples by scientists at NASA and other institutions.

Bennu is made of fragments from a larger parent asteroid destroyed by a collision in the asteroid belt, between the orbits of Mars and Jupiter. One of the papers, co-led by Jessica Barnes at the University of Arizona, Tucson, and Ann Nguyen of NASA’s Johnson Space Center in Houston and published in the journal Nature Astronomy, suggests that Bennu’s ancestor was made up of material that had diverse origins—near the Sun, far from the Sun, and even beyond our solar system.

The analyses show that some of the materials in the parent asteroid, despite very low odds, escaped various chemical processes driven by heat and water and even survived the extremely energetic collision that broke it apart and formed Bennu.

“We traced the origins of these initial materials accumulated by Bennu’s ancestor,” said Nguyen. “We found stardust grains with compositions that predate the solar system, organic matter that likely formed in interstellar space, and high temperature minerals that formed closer to the Sun. All of these constituents were transported great distances to the region that Bennu’s parent asteroid formed.”

The chemical and atomic similarities of samples from Bennu, the asteroid Ryugu (sampled by JAXA’s (the Japan Aerospace Exploration Agency) Hayabusa2 mission) and the most chemically primitive meteorites collected on Earth suggest their parent asteroids may have formed in a similar, distant region of the early solar system. Yet the differences from Ryugu and meteorites that were seen in the Bennu samples may indicate that this region changed over time or did not mix as well as some scientists have thought. 

Though some original constituents survived, most of Bennu’s materials were transformed by reactions with water, as reported in the paper co-led by Tom Zega of the University of Arizona and Tim McCoy of the Smithsonian’s National Museum of Natural History in Washington and published in Nature Geoscience. In fact, minerals in the parent asteroid likely formed, dissolved, and reformed over time.

“Bennu’s parent asteroid accumulated ice and dust. Eventually that ice melted, and the resulting liquid reacted with the dust to form what we see today, a sample that is 80% minerals that contain water,” said Zega. “We think the parent asteroid accumulated a lot of icy material from the outer solar system, and then all it needed was a little bit of heat to melt the ice and cause liquids to react with solids.”

Bennu’s transformation did not end there. The third paper, co-led by Lindsay Keller at NASA Johnson and Michelle Thompson of Purdue University, also published in Nature Geoscience, found microscopic craters and tiny splashes of once-molten rock – known as impact melts – on the sample surfaces, signs that the asteroid was bombarded by micrometeorites. These impacts, together with the effects of solar wind, are known as space weathering and occurred because Bennu has no atmosphere to protect it.

“The surface weathering at Bennu is happening a lot faster than conventional wisdom would have it, and the impact melt mechanism appears to dominate, contrary to what we originally thought,” said Keller. “Space weathering is an important process that affects all asteroids, and with returned samples, we can tease out the properties controlling it and use that data and extrapolate it to explain the surface and evolution of asteroid bodies that we haven’t visited.”

As the leftover materials from planetary formation 4.5 billion years ago, asteroids provide a record of the solar system’s history. But as Zega noted, we’re seeing that some of these remnants differ from what has been found in meteorites on Earth, because certain types of asteroids burn up in the atmosphere and never make it to the ground. That, the researchers point out, is why collecting actual samples is so important.

“The samples are really crucial for this work,” Barnes said. “We could only get the answers we got because of the samples. It’s super exciting that we’re finally able to see these things about an asteroid that we’ve been dreaming of going to for so long.”

The next samples NASA expects to help unravel our solar system’s story will be Moon rocks returned by the Artemis III astronauts.

NASA’s Goddard Space Flight Center provided overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator. The university leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Littleton, Colorado, built the spacecraft and provided flight operations. Goddard and KinetX Aerospace were responsible for navigating the OSIRIS-REx spacecraft. Curation for OSIRIS-REx takes place at NASA’s Johnson Space Center in Houston. International partnerships on this mission include the OSIRIS-REx Laser Altimeter instrument from the Canadian Space Agency and asteroid sample science collaboration with JAXA’s Hayabusa2 mission. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

The Lunar Environment Structural Test Rig simulates the intense cold of the lunar night, ranging from 40 Kelvin (K) to 125 K while maintaining a vacuum environment. This creates a tool by which scientists and engineers can test materials, electronics, and flight hardware for future Moon and Mars missions, characterizing their behaviors at these temperatures while also validating their ability to meet design requirements.

Facility Overview

The Lunar Environment Structural Test Rig (LESTR) approaches the problem of creating a simulated lunar environment by departing from typical fluid immersion or jacketed-and-chilled chamber systems. It does this by using a cryocooler to reject heat and bring the test section to any point desired by the test engineer, as low as 40 K or as high as 125 K in a vacuum environment. By combining high vacuum and cryogenic temperatures, LESTR enables safe, accurate, and cost-effective testing of materials and hardware destined for the Moon and beyond. Its modular setup supports a wide range of components — from spacesuits to rover wheels to electronics — while laying the foundation for future Moon and Mars mission technologies.

Quick Facts

LESTR is a cryogenic mechanical test system built up within a conventional load frame with the goal of providing a tool to simulate the thermal-vacuum conditions of the lunar night to engineers tasked with creating the materials, tools, and machinery to succeed in NASA’s missions.

• LESTR replicates extreme lunar night environments — including temperatures as low as 40 K and high vacuum (<5×10⁻⁷ Torr) — enabling true-to-space testing without liquid cryogens.
• Unlike traditional “wet” methods, LESTR uses a cryocooler and vacuum system to create an environment accurate to the lunar surface.
• From rover wheels to spacesuits to electronics, LESTR supports static and dynamic testing across a wide range of Moon and Mars mission hardware.

• With scalable architecture and precision thermal control, LESTR lays critical groundwork for advancing the technologies of NASA’s Artemis missions and beyond.

This NASA/ESA Hubble Space Telescope image offers a new view of the nearby spiral galaxy NGC 2835, which lies 35 million light-years away in the constellation Hydra (the Water Snake). The galaxy’s spiral arms are dotted with young blue stars sweeping around an oval-shaped center where older stars reside.

This image differs from previously released images from Hubble and the NASA/ESA/CSA James Webb Space Telescope because it incorporates new data from Hubble that captures a specific wavelength of red light called H-alpha. The regions that are bright in H-alpha emission are visible along NGC 2835’s spiral arms, where dozens of bright pink nebulae appear like flowers in bloom. Astronomers are interested in H-alpha light because it signals the presence of several different types of nebulae that arise during different stages of a star’s life. Newborn, massive stars create nebulae called H II regions that are particularly brilliant sources of H-alpha light, while dying stars can leave behind supernova remnants or planetary nebulae that can also be identified by their H-alpha emission.

By using Hubble’s sensitive instruments to survey 19 nearby galaxies, researchers aim to identify more than 50,000 nebulae. These observations will help to explain how stars affect their birth neighborhoods through intense starlight and winds.

On Sept. 11, 2022, engineers at a flight control center in Turin, Italy, sent a radio signal into deep space. Its destination was NASA’s DART (Double Asteroid Redirection Test) spacecraft flying toward an asteroid more than 5 million miles away.
 
The message prompted the spacecraft to execute a series of pre-programmed commands that caused a small, shoebox-sized satellite contributed by the Italian Space Agency (ASI), called LICIACube, to detach from DART.
 
Fifteen days later, when DART’s journey ended in an intentional head-on collision with near-Earth asteroid Dimorphos, LICIACube flew past the asteroid to snap a series of photos, providing researchers with the only on-site observations of the world’s first demonstration of an asteroid deflection.
 
After analyzing LICIACube’s images, NASA and ASI scientists report on Aug. 21 in the Planetary Science Journal that an estimated 35.3 million pounds (16 million kilograms) of dust and rocks spewed from the asteroid as a result of the crash, refining previous estimates that were based on data from ground and space-based observations.
 
While the debris shed from the asteroid amounted to less than 0.5% of its total mass, it was still 30,000 times greater than the mass of the spacecraft. The impact of the debris on Dimorphos’ trajectory was dramatic: shortly after the collision, the DART team determined that the flying rubble gave Dimorphos a shove several times stronger than the hit from the spacecraft itself.
 
“The plume of material released from the asteroid was like a short burst from a rocket engine,” said Ramin Lolachi, a research scientist who led the study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
 
The important takeaway from the DART mission is that a small, lightweight spacecraft can dramatically alter the path of an asteroid of similar size and composition to Dimorphos, which is a “rubble-pile” asteroid — or a loose, porous collection of rocky material bound together weakly by gravity.
 
“We expect that a lot of near-Earth asteroids have a similar structure to Dimorphos,” said Dave Glenar, a planetary scientist at the University of Maryland, Baltimore County, who participated in the study. “So, this extra push from the debris plume is critical to consider when building future spacecraft to deflect asteroids from Earth.”

DART’s Star Witness

NASA chose Dimorphos, which poses no threat to Earth, as the mission target due to its relationship with another, larger asteroid named Didymos. Dimorphos orbits Didymos in a binary asteroid system, much like the Moon orbits Earth. Critically, the pair’s position relative to Earth allowed astronomers to measure the duration of the moonlet’s orbit before and after the collision.
 
Ground and space-based observations revealed that DART shortened Dimorphos’ orbit by 33 minutes. But these long-range observations, made from 6.8 million miles (10.9 million kilometers) away, were too distant to support a detailed study of the impact debris. That was LICIACube’s job.

After DART’s impact, LICIACube had just 60 seconds to make its most critical observations. Barreling past the asteroid at 15,000 miles (21,140 kilometers) per hour, the spacecraft took a snapshot of the debris roughly once every three seconds. Its closest image was taken just 53 miles (85.3 km) from Dimorphos’ surface.
 
The short distance between LICIACube and Dimorphos provided a unique advantage, allowing the cubesat to capture detailed images of the dusty debris from multiple angles.
 
The research team studied a series of 18 LICIAcube images. The first images in the sequence showed LICIACube’s head-on approach. From this angle, the plume was brightly illuminated by direct sunlight. As the spacecraft glided past the asteroid, its camera pivoted to keep the plume in view.

 As LICIACube looked back at the asteroid, sunlight filtered through the dense cloud of debris, and the plume’s brightness faded. This suggested the plume was made of mostly large particles — about a millimeter or more across — which reflect less light than tiny dust grains.

Since the innermost parts of the plume were so thick with debris that they were completely opaque, the scientists used models to estimate the number of particles that were hidden from view. Data from other rubble-pile asteroids, including pieces of Bennu delivered to Earth in 2023 by NASA’s OSIRIS-REx spacecraft, and laboratory experiments helped refine the estimate.
 
“We estimated that this hidden material accounted for almost 45% of the plume’s total mass,” said Timothy Stubbs, a planetary scientist at NASA Goddard who was involved with the study.
 
While DART showed that a high-speed collision with a spacecraft can change an asteroid’s trajectory, Stubbs and his colleagues note that different asteroid types, such as those made of stronger, more tightly packed material, might respond differently to a DART-like impact. “Every time we interact with an asteroid, we find something that surprises us, so there’s a lot more work to do,” said Stubbs. “But DART is a big step forward for planetary defense.”

NASA’s IMAP will use 10 science instruments to study and map the heliosphere, a vast magnetic bubble surrounding the Sun protecting our solar system from radiation incoming from interstellar space. This mission and its two rideshares will orbit the Sun near Lagrange point 1, about one million miles from Earth, where it will scan the heliosphere, analyze the composition of charged particles, and investigate how those particles move through the solar system. This will provide information on how the Sun accelerates charged particles, filling in essential puzzle pieces to understand the space weather environment across the solar system. The IMAP spacecraft also will continuously monitor solar wind and cosmic radiation. Scientists can use this information to evaluate new and improved capabilities for space weather prediction tools and models, which are vital for the health of human space explorers and the longevity of technological systems, like satellites and power grids, that can affect life on Earth.

The agency’s Carruthers Geocorona Observatory is a small satellite set to study the exosphere, the outermost part of Earth’s atmosphere. Using ultraviolet cameras, it will monitor how space weather from the Sun impacts the exosphere, which plays a crucial role in protecting Earth from space weather events that can affect satellites, communications, and power lines. The exosphere, a cloud of neutral hydrogen extending to the Moon and possibly beyond, is created by the breakdown of water and methane by ultraviolet light from the Sun, and its glow, known as the geocorona, has been observed globally only four times before this mission.

The SWFO-L1 mission, managed by NOAA and developed with NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and commercial partners, will use a suite of instruments to provide real-time measurements of solar wind, along with a compact coronagraph to detect coronal mass ejections from the Sun. The observatory, serving as an early warning beacon for potentially destructive space weather events, will enable faster and more accurate forecasts. Its 24/7 data will support NOAA’s Space Weather Prediction Center in protecting vital infrastructure, economic interests, and national security, both on Earth and in space.

David McComas, professor, Princeton University, leads the IMAP mission with an international team of 25 partner institutions. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built the spacecraft and operates the mission. NASA’s IMAP is the fifth mission in NASA’s Solar Terrestrial Probes program portfolio. The Explorers and Heliophysics Project Division at NASA Goddard manages the program for the agency’s Heliophysics Division of NASA’s Science Mission Directorate.

NASA’s Launch Services Program, based at NASA Kennedy, manages the launch service for the mission.

What does a good rover do when her back is up against a wall? Fight for science!

Curiosity indeed fought the good fight at “Río Frío,” the wall of one of the many ridges cutting through the boxwork terrain we have been systematically exploring. The observations along the wall today provide insight into the internal structure and chemistry of the ridges, hopefully giving us clues as to why they are standing proud relative to the surrounding terrain.

The structural story will be told by the large Mastcam mosaics we planned, covering the ridge from base to top, and from a MAHLI mosaic covering a horizon of the wall filled with resistant nodules and smooth, swooping surfaces cutting in all directions that are likely veins. The mosaic target, “Jardín de las Delicias,” will surely yield a surfeit of Martian delights. The chemical story will be told by APXS analysis of the nodule-filled target “Minimini” and SuperCam analysis of a vein at “El Tapado.” In contrast to the ridge itself, we planned a Mastcam mosaic of part of the hollow at the base of the ridge at target “Playa Zapatilla.” 

Beyond the ridge, we planned Mastcam and ChemCam imaging of the “Paniri” and “Mishe Mokwa” buttes, respectively, and sky observations with Navcam and Mastcam. DAN, RAD, and REMS run periodically through the plan keeping their eye on the Martian environment. Our drive will take us to a smaller ridge perpendicular to Río Frío, where we will once again fight to learn the secrets these ridges have to tell about  Mars’ past.

Editor’s Note: This article was updated Aug. 20, 2025, to correct the number of years of training data used and the model accuracy. The original article said the model was trained on 14 years of Solar Dynamics Observatory data and surpassed existing benchmarks by 15%; the model was actually trained on 9 years of data and surpassed existing benchmarks by 16%.

NASA is turning up the heat in solar science with the launch of the Surya Heliophysics Foundational Model, an artificial intelligence (AI) model trained on 9 years of observations from NASA’s Solar Dynamics Observatory. 

Developed by NASA in partnership with IBM and others, Surya uses advances in AI to analyze vast amounts of solar data, helping scientists better understand solar eruptions and predict space weather that threatens satellites, power grids, and communication systems. The model can be used to provide early warnings to satellite operators and helps scientists predict how the Sun’s ultraviolet output affects Earth’s upper atmosphere.

Preliminary results show Surya is making strides in solar flare forecasting, a long-standing challenge in heliophysics. Surya, with its ability to generate visual predictions of solar flares two hours into the future, marks a major step towards the use of AI for operational space weather prediction. These initial results surpass existing benchmarks by 16%. By providing open access to the model on HuggingFace and the code on GitHub, NASA encourages the science and applications community to test and explore this AI model for innovative solutions that leverage the unique value of continuous, stable, long-duration datasets from the Solar Dynamics Observatory.

The model’s success builds directly on the Solar Dynamics Observatory’s long-term database. Launched in 2010, NASA’s Solar Dynamics Observatory has provided an unbroken, high-resolution record of the Sun for nearly 15 years through capturing images every 12 seconds in multiple wavelengths, plus precise magnetic field measurements. This stable, well-calibrated dataset, spanning an entire solar cycle, is uniquely suited for training AI models like Surya, enabling them to detect subtle patterns in solar behavior that shorter datasets would miss.

Surya’s strength lies in its foundation model architecture, which learns directly from raw solar data. Unlike traditional AI systems that require extensive labeling, Surya can adapt quickly to new tasks and applications. Applications include tracking active regions, forecasting flare activity, predicting solar wind speed, and integrating data from other observatories including the joint NASA-ESA Solar and Heliospheric Observatory mission and NASA’s Parker Solar Probe.

“We are advancing data-driven science by embedding NASA’s deep scientific expertise into cutting-edge AI models,” said Kevin Murphy, chief science data officer at NASA Headquarters in Washington. “By developing a foundation model trained on NASA’s heliophysics data, we’re making it easier to analyze the complexities of the Sun’s behavior with unprecedented speed and precision. This model empowers broader understanding of how solar activity impacts critical systems and technologies that we all rely on here on Earth.”

Solar storms pose significant risks to our technology-dependent society. Powerful solar events energize Earth’s ionosphere, resulting in substantial GPS errors or complete signal loss to satellite communications. They also pose risks to power grids, as geomagnetically induced currents from coronal mass ejections can overload transformers and trigger widespread outages.

In commercial aviation, solar flares can disrupt radio communications and navigation systems while exposing high-altitude flights to increased radiation. The stakes are even higher for human spaceflight. Astronauts bound for the Moon or Mars may need to depend on precise predictions to shelter from intense radiation during solar particle events.

The Sun’s influence extends to the growing number of low Earth orbit satellites, including those that deliver global high-speed internet. As solar activity intensifies, it heats Earth’s upper atmosphere, increasing drag that slows satellites, pulls them from orbit, and causes premature reentry. Satellite operators often struggle to forecast where and when solar flares might affect these satellites.

“Our society is built on technologies that are highly susceptible to space weather,” said Joseph Westlake, Heliophysics Division director at NASA Headquarters. “Just as we use meteorology to forecast Earth’s weather, space weather forecasts predict the conditions and events in the space environment that can affect Earth and our technologies. Applying AI to data from our heliophysics missions is a vital step in increasing our space weather defense to protect astronauts and spacecraft, power grids and GPS, and many other systems that power our modern world.”

While Surya is designed to study the Sun, its architecture and methodology are adaptable across scientific domains. From planetary science to Earth observation, the project lays the foundational infrastructure for similar AI efforts in diverse domains.

Surya is part of a broader NASA push to develop open-access, AI-powered science tools. Both the model and training datasets are freely available online to researchers, educators, and students worldwide, lowering barriers to participation and sparking new discoveries.

Surya’s training was supported in part by the National Artificial Intelligence Research Resource (NAIRR) Pilot, a National Science Foundation (NSF)-led initiative that provides researchers with access to advanced computing, datasets, and AI tools. The NAIRR Pilot brings together federal and industry resources, such as computing power from NVIDIA, to expand access to the infrastructure needed for cutting-edge AI research.

“This project shows how the NAIRR Pilot is uniting federal and industry AI resources to accelerate scientific breakthroughs,” said Katie Antypas, director of NSF’s Office of Advanced Cyberinfrastructure. “With support from NVIDIA and NSF, we’re not only enabling today’s research, we’re laying the groundwork for a national AI network to drive tomorrow’s discoveries.”

Surya is part of a larger effort championed and supported by NASA’s Office of the Chief Science Data Officer and Heliophysics Division, the NSF , and partnering universities to advance NASA’s scientific missions through innovative data science and AI models. Surya’s AI architecture was jointly developed by the Interagency Implementation and Advanced Concepts Team (IMPACT) under the Office of Data Science and Informatics  at NASA’s Marshall Space Flight Center in Huntsville, Alabama; IBM; and a collaborative science team.

The science team, assembled by NASA Headquarters, consisted of experts from the Southwest Research Institute in San Antonio, Texas; the University of Alabama in Huntsville in Huntsville, Alabama; the University of Colorado Boulder in Boulder, Colorado; Georgia State University in Atlanta, Georgia; Princeton University in Princeton, New Jersey; NASA’s SMD’s Heliophysics Division; NASA’s Goddard Space Flight Center in Greenbelt, Maryland; NASA’s Jet Propulsion Laboratory in Pasadena, California; and the SETI Institute in Mountain View, California.

Earth Planning Date: Monday, Aug. 18, 2025

The downlink data from our weekend activities arrived on Earth as we started planning this morning. As the APXS payload uplink and downlink lead, I assess the downlink data to ensure that our observations executed and that the instrument is healthy before we can proceed with the day’s activities. We also need that downlink data to assess which targets we can safely touch with Curiosity’s arm, to place APXS and MAHLI to analyze chemistry and closeup textures, respectively, as well as target for Mastcam and ChemCam, and plan the next drive. Because of the relatively late downlink, we all waited patiently for the necessary data to be processed before we could really start to plan in earnest. 

It is always exciting to see our new parking spot and the view in front of the rover. Today was no exception. The drive executed as planned and we are on stable ground, which will enable us to unstow the arm for contact science with APXS and MAHLI.

We selected a representative bedrock patch (“Gil”) that was large enough and smooth enough to brush for dust removal, and to place APXS and MAHLI on. ChemCam will also analyze this target with LIBS, and Mastcam will capture a documentation image. The bedrock at this location is representative of an intermediate zone between the large resistant ridges and hollows that comprise the boxwork terrain that we are currently exploring. Mastcam will image the wall of a prominent resistant ridge that we are driving to (“Río Frío”), as well as a narrow, sand-filled trough (“Cusi Cusi”). The remote long-distance imaging capabilities of ChemCam will be used to look at the base of the Mishe Mokwa butte, off to the east.

Observations to monitor the atmosphere are also planned before we drive away from this location. They include a Navcam large dust-devil survey and suprahorizon movie, and a Mastcam tau observation to observe dust in the atmosphere. After the touch (and targeted science) part of this touch-and-go plan, the drive (go part) should take us about 36 meters (about 118 feet) to the wall of Río Frío. (see associated image). 

After the drive, we will document the ground beneath the rover’s wheels with MARDI before some untargeted science. Mastcam will again image Río Frío in early morning light, trying to highlight structures and veins that might be present, and ChemCam will utilize their autonomous targeting capabilities to analyze a bedrock target in our new workspace. Two more atmospheric observations are also squeezed in before we hand over to the next plan: a Navcam cloud-altitude observation and line-of-sight scan. 

Standard REMS, DAN and RAD activities round out this jam-packed plan. The downlink was well worth the wait!
