Crew members on the International Space Station periodically conduct spacewalks to perform a variety of tasks such as installing, upgrading, and repairing equipment. During a spacewalk on May 1, astronauts installed hardware to support the planned addition of a seventh roll-out solar array on the exterior of the space station. Each of these arrays produces more than 20 kilowatts of electricity and together they will increased power production by up to 30%, enabling more scientific operations on the orbiting lab.
NASA astronaut Butch Wilmore collects samples from the exterior of the space station for ISS External Microorganisms.NASA Some spacewalks include operations for scientific research. On January 20, 2025, crew members collected samples for ISS External Microorganisms, an investigation examining whether microorganisms have exited through station vents and can survive in space. Results could help determine changes needed in design of spacecraft (including spacesuits) to prevent human-associated microbes from contaminating Mars and other exploration destinations.
Radiation monitoring
CSA astronaut Dave Williams on a spacewalk in 2007. CSA studied the radiation dose crew members experience while outside the station.NASA The CSA (Canadian Space Agency) investigation EVA Radiation Monitoring, used a miniature, power-efficient wireless radiation measurement system or dosimeter worn by crew members during spacewalks. This type of device could help identify parts of the body that are exposed to the highest radiation levels during spacewalks. Results showed that this type of device is a feasible way to monitor individual dose during spacewalks. The device also has potential uses on Earth, such as monitoring radiation exposure during cancer treatments.
Spacesuit technology
Spacesuits are essentially one-person spacecraft that protect their wearers from the hazards of space, including radiation and extreme temperatures. Space station research is helping improve the suits and tools for spacewalks and activities outside spacecraft and for the exploration of the Moon and Mars.
SpaceSkin on ExHAM, a JAXA (Japan Aerospace Exploration Agency) investigation, evaluated the durability of a fabric with imbedded sensors to detect damage. Sensors integrated into the exposed outermost layer of a spacesuit could detect damage such as impacts from micrometeoroids. Researchers documented factors to consider in design of textiles with sensing capabilities as well as the ability to withstand the hazards of space. Such fabrics could be integrated into spacesuits and habitats to help protect astronauts on spacewalks and future exploration missions.
NASA astronaut Patrick G. Forrester works with the MISSE facility.NASA Researchers use the Materials International Space Station Experiment or MISSE facility on the exterior of the space station for experiments exposing various materials and components to the harsh environment of space. Along with solar cells, electronics, and coatings, MISSE-7 tested pristine fibers from Apollo mission spacesuits and others scratched by lunar dust to examine the combined effects of abrasion and radiation damage. Researchers report that the fabrics significantly degraded, suggesting the need for ways to prevent or mitigate radiation damage to spacesuits on extended missions to the Moon.
MISSE-9 tested spacesuit materials treated with shear-thickening fluids. These suspensions of tiny particles in a fluid react to stress by quickly changing from a liquid to a solid. The research showed that the materials maintained their mechanical performance characteristics and puncture resistance after extended exposure.
Keeping cool also is important on a spacewalk, where temperatures can reach 250 degrees. SERFE, or Spacesuit Evaporation Rejection Flight Experiment, tested a technology using water evaporation to remove heat from a spacesuit so crew members and equipment remain at appropriate temperatures during spacewalks. A current cooling method, called sublimation, exposes small amounts of water to space, causing it to freeze and then turn into vapor that disperses, removing heat as it does so. The SERFE technology may be less susceptible to water contamination than sublimation.
Exiting station
The Nanoracks Bishop Airlock is attached to the Canadarm2 robotic arm as the International Space Station orbits 264 miles above the Atlantic Ocean off the coast of Brazil. Ocean off the coast of southern Brazil at the time of this photograph.NASA Crew members use specialized airlocks to exit the station for spacewalks. Airlocks also make it possible to deploy satellites and other external equipment. The Nanoracks Bishop Airlock was the first commercially owned and operated airlock installed on the space station. Its size, design, and automation enable faster and more efficient movement of materials out of and into the station, reducing the crew and robotics time needed. In addition to facilitating spacewalks, this facility could support increased commercial use of the space station and expand research capabilities.

Take a Tour of the Cosmos with New Interactives from NASA’s Universe of Learning
Ready for a tour of the cosmos? NASA’s Universe of Learning has released a new, dynamic way for lifelong learners to explore NASA’s breathtaking images of the universe—ViewSpace interactive Image Tours. ViewSpace has an established track record of providing museums, science centers, libraries, and other informal learning environments with free, web-based videos and digital interactives—like its interactive Image Sliders. These new Image Tours are another unique experience from NASA’s Universe of Learning, created through a collaboration between scientists that operate NASA telescopes and experts well-versed in the most modern methods of learning. Hands-on, self-directed learning resources like these have long been valued by informal learning sites as effective means for engaging and intriguing users with the latest discoveries from NASA’s space telescope missions—while encouraging lifelong learners to continue their passionate exploration of the stars, galaxies, and distant worlds.
With these new ViewSpace Image Tours, visitors can take breathtaking journeys through space images that contain many exciting stories. The “Center of the Milky Way Galaxy” Tour, for example, uses breathtaking images from NASA’s Hubble, Spitzer, and Chandra X-ray telescopes and includes eleven Tour Stops, where users can interact with areas like “the Brick”—a dense, dark cloud of hydrogen molecules imaged by Spitzer. Another Tour Stop zooms toward the supermassive black hole, Sagittarius A*, offering a dramatic visual journey to the galaxy’s core.
In other tours, like the “Herbig-Haro 46/47” Tour, learners can navigate through points of interest in an observation from a single telescope mission. In this case, NASA’s James Webb Space Telescope provides the backdrop where lifelong learners can explore superheated jets of gas and dust being ejected at tremendous speeds from a pair of young, forming stars. The power of Webb turns up unexpected details in the background, like a noteworthy distant galaxy famous for its uncanny resemblance to a question mark. Each Interactive Image Tour allows people to examine unique features through videos, images, or graphical overlays to identify how those features have formed in ways that static images alone can’t convey.
These tours, which include detailed visual descriptions for each Tour Stop, illuminate the science behind the beauty, allowing learners of all ages to develop a greater understanding of and excitement for space science, deepening their engagement with astronomy, regardless of their prior experience. Check out the About the Interactives page on the ViewSpace website for a detailed overview of how to use the Image Tours.
ViewSpace currently offers three Image Tours, and the collection will continue growing:
