NASA Challenge Winners Cook Up New Industry Developments
NASA invests in technologies that have the potential to revolutionize space exploration, including the way astronauts live in space. Through the Deep Space Food Challenge, NASA, in partnership with CSA (Canadian Space Agency), sought novel food production systems that could provide long-duration human space exploration missions with safe, nutritious, and tasty food. Three winners selected last summer are now taking…

NASA-Developed Printable Metal Can Take the Heat
Until now, additive manufacturing, commonly known as 3D printing, of engine components was limited by the lack of affordable metal alloys that could withstand the extreme temperatures of spaceflight. Expensive metal alloys were the only option for 3D printing engine parts until NASA’s Glenn Research Center in Cleveland, Ohio, developed the GRX-810 alloy. The primary metals in the GRX-810 alloy include nickel,…

Human Rating and NASA-STD-3001
Human-rating is a critical certification process that validates the safety, reliability, and suitability of space systems—including orbiters, launch vehicles, rovers, spacesuits, habitats, and other crewed elements—for human use and interaction. This process ensures that systems are designed not only to protect human life but also to accommodate human needs and effectively integrate human capabilities. Human-rating requires that systems can tolerate failures,…

Countdown to Space Station’s Silver Jubilee with Silver Research
This November marks a quarter century of continuous human presence aboard the International Space Station, which has served as a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including human missions to the Moon and Mars. To kick off the orbiting laboratory’s silver 25th anniversary countdown, here are a few silver-themed science investigations that…

Spacewalk Pop-Up
Former NASA astronaut Shane Kimbrough is photographed as he left the airlock hatch during a spacewalk on Jan. 13, 2017. Kimbrough performed nine spacewalks during his three spaceflights. He retired in July 2022. Astronauts conduct spacewalks to perform maintenance on the space station, install new equipment, or deploy science experiments. These activities also inform future missions like the Artemis campaign and exploring Mars;…

NASA Seeks Proposals for 2026 Human Exploration Rover Challenge
NASA now is accepting proposals from student teams for a contest to design, build, and test rovers for Moon and Mars exploration through Sept. 15. Known as the Human Exploration Rover Challenge, student rovers should be capable of traversing a course while completing mission tasks. The challenge handbook has guidelines for remote-controlled and human-powered divisions. The cover of the HERC 2026 handbook, which is…

Summer Triangle Corner: Altair
Altair is the last stop on our trip around the Summer Triangle! The last star in the asterism to rise for Northern Hemisphere observers before summer begins, brilliant Altair is high overhead at sunset at the end of the season in September. Altair might be the most unusual of the three stars of the Triangle, due to its great speed:…
