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.

Three Martian dust devils can be seen near the rim of Jezero Crater in this short video made of images taken by a navigation camera aboard NASA’s Perseverance rover on Sept. 6, 2025. The microphone on the rover’s SuperCam previously captured audio when a dust devil passed over.

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.
The SuperCam microphone on NASA’s Perseverance captured this recording of the sounds of electrical discharge as a dust devil passed over the Mars rover on Oct. 12, 2024.

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.

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.
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.”

Motiv Space Systems
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.
Researchers from NASA’s Jet Propulsion Laboratory in Southern California monitor a research drone in the Dumont Dunes area of the Mojave Desert in September as part of a test campaign to develop navigation software to guide future rotorcraft on Mars.

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.
The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft, three new papers published Tuesday by the journals Nature Geosciences and Nature Astronomy present remarkable discoveries: sugars essential for biology, a gum-like substance not seen before in astromaterials, and an unexpectedly high abundance of dust produced by supernova explosions.
Sugars essential to life
Scientists led by Yoshihiro Furukawa of Tohoku University in Japan found sugars essential for biology on Earth in the Bennu samples, detailing their findings in the journal Nature Geoscience. The five-carbon sugar ribose and, for the first time in an extraterrestrial sample, six-carbon glucose were found. Although these sugars are not evidence of life, their detection, along with previous detections of amino acids, nucleobases, and carboxylic acids in Bennu samples, show building blocks of biological molecules were widespread throughout the solar system.
For life on Earth, the sugars deoxyribose and ribose are key building blocks of DNA and RNA, respectively. DNA is the primary carrier of genetic information in cells. RNA performs numerous functions, and life as we know it could not exist without it. Ribose in RNA is used in the molecule’s sugar-phosphate “backbone” that connects a string of information-carrying nucleobases.
“All five nucleobases used to construct both DNA and RNA, along with phosphates, have already been found in the Bennu samples brought to Earth by OSIRIS-REx,” said Furukawa. “The new discovery of ribose means that all of the components to form the molecule RNA are present in Bennu.”
The discovery of ribose in asteroid samples is not a complete surprise. Ribose has previously been found in two meteorites recovered on Earth. What is important about the Bennu samples is that researchers did not find deoxyribose. If Bennu is any indication, this means ribose may have been more common than deoxyribose in environments of the early solar system.
Researchers think the presence of ribose and lack of deoxyribose supports the “RNA world” hypothesis, where the first forms of life relied on RNA as the primary molecule to store information and to drive chemical reactions necessary for survival.
A team of Japanese and US scientists have discovered the bio-essential sugars ribose and glucose in samples of asteroid Bennu that were collected by NASA’s OSIRIS-REx mission. This finding builds on the earlier discovery of nucleobases (the genetic components of DNA and RNA), phosphate, and amino acids (the building blocks of proteins) in the Bennu samples, showing that the molecular ingredients of life could have been delivered to early Earth by meteorites.

“Present day life is based on a complex system organized primarily by three types of functional biopolymers: DNA, RNA, and proteins,” explains Furukawa. “However, early life may have been simpler. RNA is the leading candidate for the first functional biopolymer because it can store genetic information and catalyze many biological reactions.”
The Bennu samples also contained one of the most common forms of “food” (or energy) used by life on Earth, the sugar glucose, which is the first evidence that an important energy source for life as we know it was also present in the early solar system.
Mysterious, ancient ‘gum’
A second paper, in the journal Nature Astronomy led by Scott Sandford at NASA’s Ames Research Center in California’s Silicon Valley and Zack Gainsforth of the University of California, Berkeley, reveals a gum-like material in the Bennu samples never seen before in space rocks – something that could have helped set the stage on Earth for the ingredients of life to emerge. The surprising substance was likely formed in the early days of the solar system, as Bennu’s young parent asteroid warmed.
Once soft and flexible, but since hardened, this ancient “space gum” consists of polymer-like materials extremely rich in nitrogen and oxygen. Such complex molecules could have provided some of the chemical precursors that helped trigger life on Earth, and finding them in the pristine samples from Bennu is important for scientists studying how life began and whether it exists beyond our planet.
On this primitive asteroid that formed in the early days of the solar system, we’re looking at events near the beginning of the beginning.
Scott SandFord
Astrophysicist, NASA’s Ames Research Center
Bennu’s ancestral asteroid formed from materials in the solar nebula – the rotating cloud of gas and dust that gave rise to the solar system – and contained a variety of minerals and ices. As the asteroid began to warm, due to natural radiation, a compound called carbamate formed through a process involving ammonia and carbon dioxide. Carbamate is water soluble, but it survived long enough to polymerize, reacting with itself and other molecules to form larger and more complex chains impervious to water. This suggests that it formed before the parent body warmed enough to become a watery environment.
“With this strange substance, we’re looking at, quite possibly, one of the earliest alterations of materials that occurred in this rock,” said Sandford. “On this primitive asteroid that formed in the early days of the solar system, we’re looking at events near the beginning of the beginning.”
Using an infrared microscope, Sandford’s team selected unusual, carbon-rich grains containing abundant nitrogen and oxygen. They then began what Sandford calls “blacksmithing at the molecular level,” using the Molecular Foundry at Lawrence Berkeley National Laboratory (Berkeley Lab) in Berkeley, California. Applying ultra-thin layers of platinum, they reinforced a particle, welded on a tungsten needle to lift the tiny grain, and shaved the fragment down using a focused beam of charged particles.
A microscopic particle of asteroid Bennu, brought to Earth by NASA’s OSIRIS-REx mission, is manipulated under a transmission electron microscope. In order to move the fragment for further analysis, researchers first reinforced it with thin strips of platinum (the “L” shape on the particle’s surface) then welded a tungsten microneedle to it. The asteroid fragment measures 30 micrometers (about one-one thousandth of an inch) across.
NASA/University of California, Berkeley
When the particle was a thousand times thinner than a human hair, they analyzed its composition via electron microscopy at the Molecular Foundry and X-ray spectroscopy at Berkeley Lab’s Advanced Light Source. The ALS’s high spatial resolution and sensitive X-ray beams enabled unprecedented chemical analysis.
“We knew we had something remarkable the instant the images started to appear on the monitor,” said Gainsforth. “It was like nothing we had ever seen, and for months we were consumed by data and theories as we attempted to understand just what it was and how it could have come into existence.”
The team conducted a slew of experiments to examine the material’s characteristics. As the details emerged, the evidence suggested the strange substance had been deposited in layers on grains of ice and minerals present in the asteroid.
It was also flexible – a pliable material, similar to used gum or even a soft plastic. Indeed, during their work with the samples, researchers noticed the strange material was bendy and dimpled when pressure was applied. The stuff was translucent, and exposure to radiation made it brittle, like a lawn chair left too many seasons in the sun.
“Looking at its chemical makeup, we see the same kinds of chemical groups that occur in polyurethane on Earth,” said Sandford, “making this material from Bennu something akin to a ‘space plastic.’”
The ancient asteroid stuff isn’t simply polyurethane, though, which is an orderly polymer. This one has more “random, hodgepodge connections and a composition of elements that differs from particle to particle,” said Sandford. But the comparison underscores the surprising nature of the organic material discovered in NASA’s asteroid samples, and the research team aims to study more of it.
By pursuing clues about what went on long ago, deep inside an asteroid, scientists can better understand the young solar system – revealing the precursors to and ingredients of life it already contained, and how far those raw materials may have been scattered, thanks to asteroids much like Bennu.
Abundant supernova dust
Another paper in the journal Nature Astronomy, led by Ann Nguyen of NASA’s Johnson Space Center in Houston, analyzed presolar grains – dust from stars predating our solar system – found in two different rock types in the Bennu samples to learn more about where its parent body formed and how it was altered by geologic processes. It is believed that presolar dust was generally well-mixed as our solar system formed. The samples had six-times the amount of supernova dust than any other studied astromaterial, suggesting the asteroid’s parent body formed in a region of the protoplanetary disk enriched in the dust of dying stars.
The study also reveals that, while Bennu’s parent asteroid experienced extensive alteration by fluids, there are still pockets of less-altered materials within the samples that offer insights into its origin.

“These fragments retain a higher abundance of organic matter and presolar silicate grains, which are known to be easily destroyed by aqueous alteration in asteroids,” said Nguyen. “Their preservation in the Bennu samples was a surprise and illustrates that some material escaped alteration in the parent body. Our study reveals the diversity of presolar materials that the parent accreted as it was forming.”
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 CSA (Canadian Space Agency) and asteroid sample science collaboration with JAXA’s (Japan Aerospace Exploration Agency’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.

NASA is marking America’s 250th year with a bold new symbol of the nation’s relentless drive to explore.
The America 250 emblem is now on the twin solid rocket boosters of the SLS (Space Launch System) rocket for Artemis II — the powerhouse that will launch a crew of four around the Moon next year. Unveiled Tuesday, the design echoes the America 250 Commission’s Spirit of Innovation theme, honoring a country that has never stopped pushing the horizon forward.
At NASA’s Kennedy Space Center in Florida, technicians spent recent weeks carefully applying the emblem on the rocket inside the Vehicle Assembly Building — the same place where rockets for Apollo once stood. Engineers are running final tests on SLS and the Orion spacecraft as preparations intensify for Artemis II.
The roughly 10-day Artemis II journey around the Moon will mark a defining moment in this new era of American exploration — paving the way for U.S. crews to land on the lunar surface and ultimately push onward to Mars.
America’s spirit of discovery is alive, and Artemis is carrying it to the Moon and beyond.
On Nov. 2, 2025, NASA honored 25 years of continuous human presence aboard the International Space Station. What began as a fragile framework of modules has evolved into a springboard for international cooperation, advanced scientific research and technology demonstrations, the development of a low Earth orbit economy, and NASA’s next great leaps in exploration, including crewed missions to the Moon and Mars.
The first expedition

This legacy of achievement in global human endeavors began with the first crew’s arrival to the space station on Nov. 2, 2000. Expedition 1 crew members NASA astronaut William M. Shepherd and Russian Aviation and Space Agency, now Roscosmos, cosmonauts Yuri P. Gidzenko and Sergei K. Krikalev launched from the Baikonur Cosmodrome in Kazakhstan two days prior. After a successful docking, the crew transferred aboard the station and began bringing it to life. Their primary tasks during their four-month mission included installing and activating the life support and communications systems and working with three visiting space shuttle crews to continue the station’s assembly. The trio returned to Earth in March 2001 aboard space shuttle Discovery, after having turned the station over to the Expedition 2 crew.
(Space)walking into history

Assembly and maintenance of the International Space Station would not be possible without the skilled work of crew members performing intricate tasks, in bulky spacesuits, in the harsh environment of space. In addition to station upkeep, spacewalks provide a platform for testing and improving spacesuits and tools – critical information for future exploration of the Moon and Mars. Other spacewalks have included operations for scientific research. In Jan. 2025, for example, crew members collected samples for an investigation examining whether microorganisms have exited through station vents and can survive in space, to better inform spacecraft design that helps prevent human contamination of Mars and other destinations.
More than 270 spacewalks dedicated to the space station have been accomplished in the last quarter century. Several made station and human spaceflight history:
May 1999: NASA astronaut Tamara Jernigan became the first woman to complete a spacewalk at the space station, in support of its construction.
September 2000: Also during space station assembly, NASA astronaut Edward T. “Ed” Lu and Roscosmos cosmonaut Yuri I. Malenchenko conducted the first U.S.-Russian spacewalk.
March 10, 2001: NASA astronauts James Voss and Susan Helms set the record for longest spacewalk in U.S. history, at 8 hours and 56 minutes.
First spacewalks by international partners included:
April 2001 – Canadian Space Agency astronaut Chris Hadfield
July 2005 – Japan Aerospace Exploration Agency astronaut Soichi Noguchi
Aug. 2006 – European Space Agency astronaut Thomas Reiter
Feb. 26, 2004: NASA astronaut Mike Foale and Russian cosmonaut Aleksandr Y. Kaleri complete the first spacewalk with no one inside the station.
Oct. 18, 2019: The first all-female spacewalk in history, conducted by NASA astronauts Christina Koch and Jessica Meir.

The International Space Station welcomed its first commercial crew members on May 31, 2020, when former NASA astronauts Robert Behnken and Douglas Hurley joined Expedition 63 Commander and NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner aboard the orbiting laboratory.
Behnken and Hurley lifted off from Kennedy Space Center in Florida the day before on NASA’s SpaceX Demo-2 test flight – the first launch of American astronauts from U.S. soil since the space shuttle’s retirement in 2011.
The duo quickly integrated with the rest of the crew and participated in a number of scientific experiments, spacewalks, and public engagement events during their 62 days aboard station. Overall, the pair spent 64 days in orbit, completed 1,024 orbits around Earth, and contributed more than 100 hours of time to supporting the orbiting laboratory’s investigations before splashing down on Aug. 2.
Successful completion of the Demo-2 mission paved the way for regular SpaceX flights carrying astronauts to and from the space station. With another certified crew transportation system in place, the International Space Station Program added research time and increased the opportunity for discovery aboard humanity’s testbed for exploration, including preparations for human exploration of the Moon and Mars.

On Sept. 27, 2023, NASA astronaut Frank Rubio returned to Earth after spending 371 days aboard the International Space Station—the longest single spaceflight by a U.S. astronaut in history. His mission surpassed the previous record of 355 days, set by NASA astronaut Mark Vande Hei, and provided scientists with an unprecedented look at how the human body adapts to more than a year in microgravity.
Rubio’s record-setting mission supported six human research studies, including investigations into diet, exercise, and overall physiology and psychology. He was the first astronaut to test whether limited workout equipment could still maintain health and fitness, an important consideration for future spacecraft with tighter living quarters. He also contributed biological samples, surveys, and tests for NASA’s Spaceflight Standard Measures, a study that collects health data from astronauts to better understand how the body adapts to space—knowledge that helps prepare crews for the Artemis campaign to the Moon and future trips to Mars.
Alongside his fellow crew members, Rubio participated in dozens of investigations and technology demonstrations, from growing tomato plants with hydroponic and aeroponic techniques to materials science experiments that advance spacecraft design.
Long-duration missions help inform future spaceflight and lay the groundwork for the next era of human exploration.
A global foundation for growing a low Earth orbit economy
Facilities around the world support the operation and management of the International Space Station.
NASA
The space station is one of the most ambitious international collaborations ever attempted.It brings together international flight crews, multiple launch vehicles, globally distributed launch and flight operations, training, engineering, and development facilities, communications networks, and the international scientific research community for the benefit of all humanity.
An international partnership of space agencies operates the elements of the orbiting laboratory: NASA, Roscosmos, ESA (European Space Agency), JAXA (Japan Aerospace Exploration Agency), and CSA (Canadian Space Agency). Each partner takes primary responsibility for managing and running the station hardware it provides, as well as on-Earth construction, launch support, mission operations, communications, and research and technology facilities that support the station.
At least 290 individuals representing 26 countries, and the five international partners have visited the orbiting laboratory during its 25 years of continuous human presence. Some of those visitors flew to the station on private astronaut missions. These missions contribute to scientific, outreach, and commercial activities. They also help demonstrate the demand for future commercial space stations and are an important component of NASA’s strategy for enabling a robust and competitive commercial economy in low Earth orbit.
The results of the international partnership created through the space station and its accomplishments exemplifies how countries can work together to overcome complex challenges and achieve collaborative goals.

De plus, une organisation réfléchie favorise le référencement SEO en intégrant naturellement des mots-clés et des expressions liées.
Utiliser des titres et sous-titres pertinents
Les titres jouent un rôle crucial pour segmenter l’article et améliorer la navigation. Par exemple, des sous-titres comme “Les planètes du Système Solaire” ou “Les caractéristiques des astres” permettent d’introduire clairement chaque thème. Ces balises H2 et H3 doivent inclure des mots-clés stratégiques pour renforcer la visibilité sur les moteurs de recherche.
Rédiger des paragraphes courts et clairs
La lisibilité est un facteur déterminant pour retenir les visiteurs. Chaque paragraphe devrait contenir 2 à 4 phrases, facilitant ainsi une lecture fluide et agréable. Une écriture concise évite la surcharge d’informations et maintient l’attention du lecteur sur les points essentiels.
Optimiser l’utilisation des images pour renforcer le contenu
Les images jouent un rôle fondamental dans l’illustration des concepts scientifiques. Utiliser des photos réalistes des planètes, diagrammes explicatifs ou infographies aide à matérialiser les informations. Chaque image doit être accompagnée d’un texte alternatif descriptif pour améliorer l’accessibilité et le référencement SEO.
Choisir des images de qualité supérieure
Privilégiez des images photoréalistes qui capturent la beauté et la complexité du Système Solaire. Cela suscite l’intérêt visuel et soutient la crédibilité de l’article. Par exemple, une représentation détaillée de la Terre ou de Jupiter peut renforcer l’impact scientifique du contenu.
Intégrer des légendes et des appels à l’action
Les légendes explicatives enrichissent la compréhension et incitent les lecteurs à approfondir leurs connaissances. Par ailleurs, insérer des appels à l’action, comme des invitations à commenter ou à partager, augmente l’interactivité et favorise l’engagement.
Améliorer la profondeur et la clarté avec des transitions efficaces
Les transitions fluides entre les sections garantissent une progression logique du contenu. Utiliser des phrases de liaison permet de connecter les idées et d’éviter les ruptures dans la lecture. Cela rend l’article plus cohérent et agréable à parcourir.
Employer des variations sémantiques pour enrichir le texte
Pour renforcer le SEO, il est utile d’intégrer des synonymes et des termes connexes comme “planètes”, “astres”, “orbites” ou “exploration spatiale”. Cette diversité lexicale élargit le champ sémantique et améliore la pertinence du contenu aux yeux des moteurs de recherche.
En appliquant ces techniques, vos articles sur le Système Solaire gagneront en clarté, en profondeur et en attractivité. Une structure optimisée associée à une utilisation stratégique des images et des appels à l’action multiplie vos chances d’augmenter l’engagement des lecteurs et de booster votre référencement naturel. Ainsi, vous contribuez efficacement à diffuser la connaissance scientifique tout en maximisant la portée de vos publications.
