Select walls at NASA’s Johnson Space Center have been transformed into works of art. Each piece reflects creativity, collaboration, and the spirit of discovery. Painted by Texas students, the murals honor the legacy of the International Space Station and 25 years of continuous human presence in space. 

The International Space Station Program Mural Project began in 2022 as part of a broader effort to bring color and inspiration into the workplace while connecting classrooms to NASA’s mission. 

“The mural collection is a reminder that today’s dreams can be tomorrow’s realities,” said Space Operations Mission Directorate Deputy Associate Administrator Joel Montalbano. “The future of space exploration depends on the imagination of our students.” 

As NASA prepares for the next giant leap through Artemis, the art on the walls serves as a reminder that every mission begins with creativity and courage. This initiative continues to inspire the next generation to Dare | Unite | Explore. While art allows for interpretation, each mural required careful planning, communication, and problem-solving, just like the work behind human spaceflight.  

The most recent mural, “Dream Big,” was installed in the hallway leading to the International Space Station Program suite on the fifth floor of building 1. Created by Texas City High School students with the International Space Station Program Mission Integration and Operations team, the artwork shows a grayscale child pulling back a curtain to reveal rockets, astronauts, and bright planetary landscapes.  

The mural’s design draws from both classic and modern art influences. The students were inspired by Van Gogh’s impressionistic style and Banksy’s Behind the Curtain, combining movement and curiosity to reflect how imagination can open the door to exploration. 

“The National Art Honor Society was honored to take on this inspiring project,” said Texas City High School art teacher Jennifer Massie. “They chose ‘Where Creativity Meets Reality’ to show how a child’s creative mind keeps moving and evolving—and that with big dreams and hard work, kids can follow in their heroes’ footsteps.” 

What started as an idea between Gary Johnson, technical manager in the International Space Station Mission Integration and Operations Office, and Raul Tijerina, then the program’s building graphics lead, has grown into a gallery-sized initiative that bridges science and creativity. 

“We want students to have the unique opportunity to contribute to NASA’s legacy through their artwork,” Johnson said. “These murals show that every mission begins with imagination and that the next generation of explorers is already helping paint humanity’s future among the stars.”  

Two murals are now housed in the hallway of the Neutral Buoyancy Laboratory’s International Space Development Integration Laboratory, known as the SDIL. The first, “Dream Explore Discover,” created by Friendswood High School students, was originally displayed in building 4 south. Under the guidance of art teacher Mandy Harris, more than 30 students designed and painted the 8-by-18-foot mural, starting with sketches and brainstorming sessions that considered how art could reflect human space exploration. The students combined their ideas into a single design celebrating the beauty and excitement of discovery. 

Elements of the mural include an astronaut’s visor reflecting the Houston skyline, zinnias symbolizing life and science connecting beyond Earth, and a small floating teddy bear representing both the dreams of children who look up to the stars and the generations of explorers who carried small tokens of home into space. It serves as a reminder of the human heart behind every mission.  

The mural also features the launch of NASA’s SLS (Space Launch System) rocket with NASA’s Orion spacecraft riding on top, heading for the next giant leap in exploration. Beside the capsule, the Orion constellation appears in the sky, symbolizing how the stars continue to guide humanity’s journey to the Moon, Mars, and beyond.  

“The Moon Now,” created by students from La Marque High School, Blocker Middle School, and Giles Middle School, is also housed at the SDIL. The artwork depicts two astronauts on the lunar surface wearing Axiom spacesuits with mirrored visors that reflect the faces of the next generation who will carry humanity back to the Moon. Individual student artworks of the Milky Way and celestial objects were collaged into the final piece, creating a tapestry of imagination and exploration. 

The remaining murals are installed in building 4 south at Johnson. In 2023, the program expanded to include Dickinson High School, whose students created “A Starry Night,” a blend of Renaissance-style painting and modern space imagery. “Everyone wanted to be involved,” said art teacher Jennifer Sumrall. “The kids loved it and did their own research on how each of NASA’s missions impacts the world.” 

“Absolute Equality: Breaking Boundaries” by Houston artist Reginald C. Adams symbolizes unity and humanity’s shared future in space exploration. Two figures share a single helmet. Patterns inspired by circuitry surround the faces and suggest the role of technology in connecting people around the world and beyond it. 

“Collaboration” was painted by La Marque High School students with art teacher Joan Finn and artist Cheryl Evans to depict the interconnected roles of visionaries, engineers, artists, and astronauts in exploration. Built from 10 stretched canvases bolted together — a nod to the station’s assembly across more than 40 missions — the mural includes the space station patch at the bottom to represent the collaboration of the 15 countries involved.

NASA Johnson thanks Joel Montalbano, who championed student engagement that connects classrooms to mission work during his tenure as International Space Station Program manager. The center also acknowledges Gary Johnson for conceiving the mural project and guiding its partnerships, Raul Tijerina for early design leadership that set the standard, Gordon Andrews for opening doors through behind-the-scenes tours, and art educators for mentoring the students who brought each mural to life.

Perseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters.

NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam microphone. The discovery, published Nov. 26 in the journal Nature, has implications for Martian atmospheric chemistry, climate, and habitability, and could help inform the design of future robotic and human missions to Mars.

A frequent occurrence on the Red Planet, dust devils form from rising and rotating columns of warm air. Air near the planet’s surface becomes heated by contact with the warmer ground and rises through the denser, cooler air above. As other air moves along the surface to take the place of the rising warmer air, it begins to rotate. When the incoming air rises into the column, it picks up speed like spinning ice skaters bringing their arms closer to their body. The air rushing in also picks up dust, and a dust devil is born.

SuperCam has recorded 55 distinct electrical events over the course of the mission, beginning on the mission’s 215thMartian day, or sol, in 2021. Sixteen have been recorded when dust devils passed directly over the rover.

Decades before Perseverance landed, scientists theorized that the friction generated by tiny dust grains swirling and rubbing against each other in Martian dust devils could generate enough of an electrical charge to eventually produce electrical arcs. Called the triboelectric effect, it’s the phenomenon at play when someone walks over a carpet in socks and then touches a metal doorknob, generating a spark. In fact, that is about the same level of discharge as what a Martian dust devil might produce.

“Triboelectric charging of sand and snow particles is well documented on Earth, particularly in desert regions, but it rarely results in actual electrical discharges,” said Baptiste Chide, a member of the Perseverance science team and a planetary scientist at L’Institut de Recherche en Astrophysique et Planétologie in France. “On Mars, the thin atmosphere makes the phenomenon far more likely, as the amount of charge required to generate sparks is much lower than what is required in Earth’s near-surface atmosphere.”

Perseverance’s SuperCam instrument carries a microphone to analyze the sounds of the instrument’s laser when it zaps rocks, but the team has also captured the sounds of wind and even the first audio recording of a Martian dust devil. Scientists knew it could pick up electromagnetic disturbance (static) and sounds of electrical discharges in the atmosphere. What they didn’t know was if such events happened frequently enough, or if the rover would ever be close enough, to record one. Then they began to assess data amassed over the mission, and it didn’t take long to find the telltale sounds of electrical activity.

Crackle, pop

“We got some good ones where you can clearly hear the ‘snap’ sound of the spark,” said coauthor Ralph Lorenz, a Perseverance scientist at the Johns Hopkins Applied Physics Lab in Laurel, Maryland. “In the Sol 215 dust devil recording, you can hear not only the electrical sound, but also the wall of the dust devil moving over the rover. And in the Sol 1,296 dust devil, you hear all that plus some of the particles impacting the microphone.”

Thirty-five other discharges were associated with the passage of convective fronts during regional dust storms. These fronts feature intense turbulence that favor triboelectric charging and charge separation, which occurs when two objects touch, transfer electrons, and separate — the part of the triboelectric effect that results in a spark of static electricity.

Researchers found electrical discharges did not seem to increase during the seasons when dust storms, which globally increase the presence of atmospheric dust, are more common on Mars. This result suggests that electrical buildup is more closely tied to the localized, turbulent lifting of sand and dust rather than high dust density alone.

Profound effects

The proof of these electrical discharges is a discovery that dramatically changes our understanding of Mars. Their presence means that the Martian atmosphere can become sufficiently charged to activate chemical reactions, leading to the creation of highly oxidizing compounds, such as chlorates and perchlorates. These strong substances can effectively destroy organic molecules (which constitute some of the components of life) on the surface and break down many atmospheric compounds, completely altering the overall chemical balance of the Martian atmosphere.

This discovery could also explain the puzzling ability of Martian methane to vanish rapidly, offering a crucial piece of the puzzle for understanding the constraints life may have faced and, therefore, the planet’s potential to be habitable.

Given the omnipresence of dust on Mars, the presence of electrical charges generated by particles rubbing together would seem likely to influence dust transport on Mars as well. How dust travels on Mars plays a central role in the planet’s climate but remains poorly understood.

Confirming the presence of electrostatic discharges will also help NASA understand potential risks to the electronic equipment of current robotic missions. That no adverse electrostatic discharge effects have been reported in several decades of Mars surface operations may attest to careful spacecraft grounding practices. The findings could also inform safety measures developed for future astronauts exploring the Red Planet.

This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (the Maiden). Through a small telescope, this galaxy appears extremely faint, giving it the nickname ‘Lost Galaxy’. With a mirror spanning nearly eight feet (2.4 meters) across and its location above Earth’s light-obscuring atmosphere, Hubble can easily observe dim galaxies like NGC 4535 and pick out features like its massive spiral arms and central bar of stars.

This image features NGC 4535’s young star clusters, which dot the galaxy’s spiral arms. Glowing-pink clouds surround many of these bright-blue star groupings. These clouds, called H II (‘H-two’) regions, are a sign that the galaxy is home to especially young, hot, and massive stars that blaze with high-energy radiation. Such massive stars shake up their surroundings by heating their birth clouds with powerful stellar winds, eventually exploding as supernovae.

The image incorporates data from an observing program designed to catalog roughly 50,000 H II regions in nearby star-forming galaxies like NGC 4535. Hubble released a previous image of NGC 4535 in 2021. Both the 2021 image and this new image incorporate observations from the PHANGS observing program, which seeks to understand the connections between young stars and cold gas. Today’s image adds a new dimension to our understanding of NGC 4535 by capturing the brilliant red glow of the nebulae that encircle massive stars in their first few million years of life.

NASA and industry partners will fly and operate a commercial robotic arm in low Earth orbit through the Fly Foundational Robots mission set to launch in late 2027. This mission aims to revolutionize in-space operations, a critical capability for sustainably living and working on other planets. By enabling this technology demonstration, NASA is fostering the in-space robotics industry to unlock valuable tools for future scientific discovery and exploration missions.   

“Today it’s a robotic arm demonstration, but one day these same technologies could be assembling solar arrays, refueling satellites, constructing lunar habitats, or manufacturing products that benefit life on Earth,” said Bo Naasz, senior technical lead for In-space Servicing, Assembly, and Manufacturing (ISAM) in the Space Technology Mission Directorate at NASA Headquarters in Washington. “This is how we build a dominant space economy and sustained human presence on the Moon and Mars.”

The Fly Foundational Robots (FFR) mission will leverage a robotic arm from small business Motiv Space Systems capable of dexterous manipulation, autonomous tool use, and walking across spacecraft structures in zero or partial gravity. This mission could enable ways to repair and refuel spacecraft, construct habitats and infrastructure in space, maintain life support systems on lunar and Martian surfaces, and serve as robotic assistants to astronauts during extended missions. Advancing robotic systems in space could also enhance our understanding of similar technologies on Earth across industries including construction, medicine, and transportation.  

To demonstrate FFR’s commercial robotic arm in space, NASA’s Space Technology Mission Directorate is contracting with Astro Digital to provide a hosted orbital test through the agency’s Flight Opportunities program.  

Guest roboticists will have the opportunity to contribute to the FFR mission, and participation will allow them to use Motiv’s robotic platform as a testbed and perform unique tasks. NASA will serve as the inaugural guest operator and is currently seeking other interested U.S. partners to participate.  

The future of in-space robotics relies on testing robotic operations in space prior to launching more complex and extensive servicing and refueling missions. Through FFR, the demonstration of Motiv’s robotic arm operations in space will begin to push open the door to endless possibilities. 

NASA’s Fly Foundational Robots demonstration is funded through the NASA Space Technology Mission Directorate’s ISAM portfolio and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Motiv Space Systems of Pasadena, California, will supply the mission’s robotic arm system through a NASA Small Business Innovation Research Phase III award. Astro Digital of Littleton, Colorado, will flight test Motiv’s robotic payload through NASA’s Flight Opportunities program managed by NASA’s Armstrong Flight Research Center in Edwards, California.

The waxing gibbous moon rises above Earth’s blue atmosphere in this photograph taken from the International Space Station on Oct. 3, 2025, as it orbited 263 miles above a cloudy Atlantic Ocean off the coast of Quebec, Canada.

In our entire solar system, the only object that shines with its own light is the Sun. That light always beams onto Earth and the Moon from the direction of the Sun, illuminating half of our planet in its orbit and reflecting off the surface of the Moon to create moonlight. Sometimes the entire face of the Moon glows brightly. Other times we see only a thin crescent of light. Sometimes the Moon seems to disappear. These shifts are called Moon phases. The waxing gibbous phase comes just before the full moon.

Next-generation drone flight software is just one of 25 technologies for the Red Planet that the space agency funded for development this year.

When NASA engineers want to test a concept for exploring the Red Planet, they have to find ways to create Mars-like conditions here on Earth. Then they test, tinker, and repeat. 

That’s why a team from NASA’s Jet Propulsion Laboratory in Southern California took three research drones to California’s Death Valley National Park and the Mojave Desert earlier this year. They needed barren, featureless desert dunes to hone navigation software. Called Extended Robust Aerial Autonomy, the work is just one of 25 projects funded by the agency’s Mars Exploration Program this past year to push the limits of future technologies. Similar dunes on Mars confused the navigation algorithm of NASA’s Ingenuity Mars Helicopter during several of its last flights, including its 72nd and final flight on the Red Planet.

“Ingenuity was designed to fly over well-textured terrain, estimating its motion by looking at visual features on the ground. But eventually it had to cross over blander areas where this became hard,” said Roland Brockers, a JPL researcher and drone pilot. “We want future vehicles to be more versatile and not have to worry about flying over challenging areas like these sand dunes.”

Whether it’s new navigation software, slope-scaling robotic scouts, or long-distance gliders, the technology being developed by the Mars Exploration Program envisions a future where robots can explore all on their own — or even help astronauts do their work.

Desert drones

NASA scientists and engineers have been going to Death Valley National Park since the 1970s, when the agency was preparing for the first Mars landings with the twin Viking spacecraft. Rubbly volcanic boulders on barren slopes earned one area the name Mars Hill, where much of this research has taken place. Almost half a century later, JPL engineers tested the Perseverance rover’s precision landing system by flying a component of it in a piloted helicopter over the park. 

For the drone testing, engineers traveled to the park’s Mars Hill and Mesquite Flats Sand Dunes in late April and early September. The JPL team received only the third-ever license to fly research drones in Death Valley. Temperatures reached as high as 113 degrees Fahrenheit (45 degrees Celsius); gathered beneath a pop-up canopy, team members tracked the progress of their drones on a laptop. 

The test campaign has already resulted in useful findings, including how different camera filters help the drones track the ground and how new algorithms can guide them to safely land in cluttered terrain like Mars Hill’s. 

“It’s incredibly exciting to see scientists using Death Valley as a proving ground for space exploration,” said Death Valley National Park Superintendent Mike Reynolds. “It’s a powerful reminder that the park is protected not just for its scenic beauty or recreational opportunities, but as a living laboratory that actively helps us understand desert environments and worlds beyond our own.”

For additional testing during the three-day excursion, the team ventured to the Mojave Desert’s Dumont Dunes. The site of mobility system tests for NASA’s Curiosity rover in 2012, the rippled dunes there offered a variation of the featureless terrain used to test the flight software in Death Valley.

“Field tests give you a much more comprehensive perspective than solely looking at computer models and limited satellite images,” said JPL’s Nathan Williams, a geologist on the team who previously helped operate Ingenuity. “Scientifically interesting features aren’t always located in the most benign places, so we want to be prepared to explore even more challenging terrains than Ingenuity did.”

Robot dogs

The California desert isn’t the only field site where Mars technology has been tested this year. In August, researchers from NASA’s Johnson Space Center in Houston ventured to New Mexico’s White Sands National Park, another desert location that has hosted NASA testing for decades. 

They were there with a doglike robot called LASSIE-M (Legged Autonomous Surface Science In Analogue Environments for Mars). Motors in the robot’s legs measure physical properties of the surface that, when combined with other data, lets LASSIE-M shift gait as it encounters terrain that is softer, looser, or crustier — variations often indicative of scientifically interesting changes. 

The team’s goal is to develop a robot that can scale rocky or sandy terrain — both of which can be hazardous to a rover — as it scouts ahead of humans and robots alike, using instruments to seek out new science.

Wings for Mars 

Another Mars Exploration Program concept funded this past year is an autonomous robot that trades the compactness of the Ingenuity helicopter for the range that comes with wings. NASA’s Langley Research Center in Hampton, Virginia, has been developing the Mars Electric Reusable Flyer (MERF), which looks like a single wing with twin propellers that allow it to lift off vertically and hover in the air. (A fuselage and tail would be too heavy for this design.) While the flyer skims the sky at high speeds, instruments on its belly can map the surface.

At its full size, the MERF unfolds to be about as long as a small school bus. Langley engineers have been testing a half-scale prototype, sending it soaring across a field on the Virgina campus to study the design’s aerodynamics and the robot’s lightweight materials, which are critical to flying in Mars’ thin atmosphere.

With other projects focused on new forms of power generation, drills and sampling equipment, and cutting-edge autonomous software, there are many new ways for NASA to explore Mars in the future.

What is AI? (Grades 5-8)

This article is for students grades 5-8.

What is AI?

Artificial intelligence, or AI, is a type of technology that helps machines and computers have “thinking” abilities similar to humans. Devices using AI can learn words and concepts, recognize objects, see patterns, or make predictions. They can also be taught how to work autonomously. AI is often used to help people understand and solve problems more quickly than they could on their own.

AI includes:

• Machine learning: This type of AI looks at large amounts of data and learns how to make fast and accurate predictions based on that data. 
• Deep learning: This type helps computers operate much like the human brain. It uses several layers of “thought” to recognize patterns and learn new information. Deep learning is a type of machine learning. 
• Generative AI: A human can use generative AI to create text, videos, images, and more. It is based on deep learning.

How is NASA using AI?

NASA has found uses for AI in many of its missions and programs.

For missions to the Moon, AI can use satellite imagery to create detailed 3D maps of dark craters. This data could help scientists plan missions, spot hazards, and even identify where future crews might find water ice. On Mars, the Perseverance rover uses AI to drive itself autonomously. It takes pictures of the ground, sees obstacles, and chooses the safest path.

AI also helps NASA search for planets outside our solar system. For example, AI has helped citizen scientists find over 10,000 pairs of binary stars. These pairs orbit each other and block each other’s light. This information could help scientists search for new planets and learn more about how stars form.

———————————————————————————————

Words to Know

Autonomous: acting or operating independently, without external control. An autonomous technology can perform duties without human intervention.

Citizen scientist: a member of the public, often a volunteer, who collects data that can be used by scientists. When members of the public participate in research in this way, it’s called citizen science.

———————————————————————————————

NASA also uses AI to support its work on Earth.  The agency uses AI to aid disaster relief efforts during and after natural disasters like hurricanes or wildfires. For example, AI can count tarps on roofs in satellite images to measure damage after a storm. NASA is also supporting flight controllers and pilots by using AI to plan better flight routes, making air travel safer and more efficient. 

AI is helping NASA explore space, protect people, and make amazing discoveries!

Advice From NASA AI Experts

“AI is a great field for people who like solving problems, building things, or asking questions about how the world works. People use AI to help doctors understand diseases, to teach robots how to explore space,  and to help communities prepare for things like floods or wildfires. If you like using technology to help people and discover new things, AI could be a great career for you!” – Krista Kinnard, NASA’s Deputy Chief AI Officer

Career Corner

NASA roles that may involve AI include:  
Astronauts: Astronauts on the International Space Station can use an AI “digital assistant” to get medical recommendations. This is helpful when communication with Earth is interrupted. It could also be useful on future missions to distant destinations like Mars.
Engineers: Engineers can use AI to help them generate designs for things like new spacecraft.
Astronomers: AI helps astronomers analyze satellite and deep space telescope data to find stars and exoplanets.
Meteorologists: Weather experts can use machine learning to make climate projections.
Programmers: Programmers can use AI to update code used in older missions, bringing it up to modern standards.
IT professionals: AI can enable IT experts to understand outages across NASA, allowing them to get programs back up and running faster.
Program managers: Program managers can use AI to plan and model NASA missions.

The Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope captured glowing cosmic dust heated by very young massive stars in unprecedented detail in this image of the Sagittarius B2 (Sgr B2) molecular cloud released on Sept. 24, 2025.

Sgr B2 is the most massive, and active star-forming region in our galaxy, located only a few hundred light years from our central supermassive black hole. While Sgr B2 has only 10% of the galactic center’s gas, it produces 50% of its stars. Astronomers want to figure out why it is so much more active than the rest of the galactic center.

MIRI has both a camera and a spectrograph that sees light in the mid-infrared region of the electromagnetic spectrum. MIRI’s view reveals colorful stars punctuated occasionally by bright clouds of gas and dust. Further research into these stars will reveal details of their masses and ages, which will help astronomers better understand the process of star formation in this dense, active galactic center region.

In some ways, Benin City is like dozens of other fast-growing cities in Nigeria. Buoyed by burgeoning industrial and agricultural sectors, the city’s population rose by 1.7 million people over the past four decades as its footprint on the West African landscape expanded several times over.

Amid bustling new networks of roads, residential neighborhoods, markets, and workshops, lie signs of a much earlier era, when the city was the seat of a powerful pre-colonial kingdom. Remnants of ancient earthworks, thought to be among the longest in the world, can even be seen in images of the city captured from space.

Benin Iya (sometimes called the Benin Earthworks, the Walls of Benin, and the Benin Moat) is a vast, cellular network of interlocking earthen walls, ramparts, and ditches that radiate outward from a central moat at the heart of the city. Built in sections over hundreds of years between the 7th and 14th centuries, the system was key to marking defensive, political, and economic boundaries and played an important role in maintaining order and stability in the Kingdom of Benin.

The OLI-2 (Operational Land Imager-2) on Landsat 9 captured this image of the remains of earthworks on January 11, 2025. The features appear as dark green lines that trace arcing patterns in a densely settled area near the airport on the west bank of the Ikpoba River. Trees and vegetation growing in the moats give the features a dark green color.

Most of the earthworks consisted of relatively narrow and shallow linear ramparts and ditches that spread widely across the landscape. Many sections have been destroyed or are too small or too obscured by modern development to be easily detected by satellites or astronauts in orbit. However, some inner sections that run through the modern Oredo, Egor, and Ikpoba-Okha areas of the city had true walls and moats and are among the most visible in Landsat imagery.

Archaeological research indicates that the earthworks spanned more than 16,000 kilometers (10,000 miles) and enclosed roughly 6,500 square kilometers (2,500 square miles)—an area as large as the U.S. state of Delaware. Such length means the features hold the Guinness World Record for being the “longest earthworks of the pre-mechanical era.” By some measures, the features were together significantly longer than the Great Wall of China.

Dramatic plumes, both large and small, spray water ice out from many locations along the famed tiger stripes near the south pole of Saturn’s moon Enceladus in this image released on Feb. 23, 2010. A study published in October 2025 analyzed data from NASA’s Cassini mission and found evidence of previously undetected organic compounds in a plume of ice particles like the ones seen here. The ice particles were ejected from the ocean that lies under Enceladus’ frozen shell. Researchers spotted not only molecules they’ve found before but also new ones that lay a potential path to chemical or biochemical activity.

In northeastern Africa, within the driest part of the Sahara, dark rocky outcrops rise above pale desert sands. Several of these formations, including Jabal Arakanū, display striking ring-shaped structures.  

Jabal Arkanū (also spelled Arkenu) lies in southeastern Libya, near the border with Egypt. Several other massifs are clustered nearby, including Jabal Al Awaynat (or Uweinat), located about 20 kilometers (12 miles) to the southeast. Roughly 90 kilometers to the west are the similarly named Arkenu structures. These circular features were once thought to have formed by meteorite impacts, but later fieldwork suggested they resulted from terrestrial geological processes.   

Arkanū’s ring-shaped structures also have an earthly origin. They are thought to have formed as magma rose toward the surface and intruded into the surrounding rock. Repeated intrusion events produced a series of overlapping rings, their centers roughly aligned toward the southwest. The resulting ring complex—composed of igneous basalt and granite—is bordered to the north by a hat-shaped formation made of sandstone, limestone, and quartz layers. 

This photograph, taken by an astronaut aboard the International Space Station on September 13, 2025, shows the massif casting long shadows across the desert. The ridges stand nearly 1,400 meters above sea level, or about 800 meters above the surrounding sandy plains. Notice several outwash fans of boulders, gravel, and sand spreading from the mountain’s base toward the bordering longitudinal dunes.   

Two wadis, or typically dry riverbeds, wind through the structure. However, water is scarce in this part of the Sahara. Past research using data from NASA and JAXA’s now-completed Tropical Rainfall Measuring Mission (TRMM) indicated that southeastern Libya, along with adjacent regions of Egypt and northern Sudan, receives only about 1 to 5 millimeters of rain per year. Slightly higher accumulations, around 5 to 10 millimeters per year, occur near Jabal Arkanū and neighboring massifs, suggesting a modest orographic effect from the mountains.  

Astronaut photograph ISS073-E-698446 was acquired on September 13, 2025, with a Nikon Z9 digital camera using a focal length of 800 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 73 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Kathryn Hansen.

NASA astronaut Chris Williams, accompanied by Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, safely arrived at the International Space Station on Thursday, expanding the orbiting laboratory’s crew to 10 for the next two weeks.

The trio launched aboard the Soyuz MS-28 spacecraft at 4:27 a.m. EST (2:27 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan. After a three-hour, two-orbit journey, the spacecraft docked at 7:34 a.m. to the space station’s Rassvet module.

Following hatch opening, expected about 10:10 a.m., the new arrivals will be welcomed by the Expedition 73 crew, including NASA astronauts Mike Fincke, Zena Cardman, and Jonny Kim; JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui; and Roscosmos cosmonauts Sergey Ryzhikov, Alexey Zubritsky, and Oleg Platonov.

NASA’s live coverage of hatch opening begins at 9:50 a.m. on NASA+, Amazon Prime, and YouTube. Learn how to watch NASA content through a variety of platforms, including social media.

During his stay aboard the space station, Williams will conduct scientific research and technology demonstrations aimed at advancing human space exploration and benefiting life on Earth. He will help install and test a new modular workout system for long-duration missions, support experiments to improve cryogenic fuel efficiency and grow semiconductor crystals in space, as well as assist NASA in designing new re-entry safety protocols to protect crews during future missions.

Expedition 74 is scheduled to begin on Monday, Dec. 8, following the departure of Kim, Ryzhikov, and Zubritsky, as they conclude an eight-month science mission aboard the orbital outpost.

Watch the change of command ceremony at 10:25 a.m. on Sunday, Dec. 7, as station leadership transfers from Ryzhikov to Fincke, live on NASA+.
