Editor’s Note: This article was updated Nov. 21, 2025 shortly after BioSentinel’s mission marked three years of operation in deep space. Astronauts live in a pretty extreme environment aboard the International Space Station. Orbiting about 250 miles above the Earth in the weightlessness of microgravity, they rely on commercial cargo missions about every two months to deliver new […]

25 Year of Scientific Discovery Aboard International Space Station
November marks 25 years of human presence aboard the International Space Station, a testament to international collaboration and human ingenuity. Since the first crew arrived on Nov. 2, 2000, NASA and its partners have conducted thousands of research investigations and technology demonstrations to advance exploration of the Moon and Mars and benefit life on Earth. […]
International Space Station: Launching NASA and Humanity into Deep Space
Curiosity and the desire to explore are traits deeply rooted in human nature. Space exploration is no exception; it reflects humanity’s timeless drive to seek new horizons, challenge our limits, and understand our universe. The advancements of modern civilization—from the electricity that powers our homes to basic hygienic breakthroughs that ensure our health— happened thanks […]

NASA’s Astrobee Robots Advance Through Strategic Partnership
NASA is continuing the Astrobee mission through a collaboration with Arkisys, Inc., of Los Alamitos, California, who was awarded a reimbursable Space Act Agreement to sustain and maintain the robotic platform aboard the International Space Station. As the agency returns astronauts to the Moon, robotic helpers like Astrobee could one day take over routine maintenance […]
Space Station Science
NASA astronaut Zena Cardman processes bone cell samples inside the Kibo laboratory module’s Life Science Glovebox on Aug. 28, 2025, as part of an experiment that tests how microgravity affects bone-forming and bone-degrading cells and explore potential ways to prevent bone loss. This research could help protect astronauts on future long-duration missions to the Moon […]
NASA Science, Cargo Launches Aboard Northrop Grumman CRS-23
NASA is sending more science, technology demonstrations, and crew supplies to the International Space Station following the successful launch of the agency’s Northrop Grumman Commercial Resupply Services 23 mission, or Northrop Grumman CRS-23. The company’s Cygnus XL spacecraft, carrying more than 11,000 pounds of cargo to the orbiting laboratory, lifted off at 6:11 p.m. EDT […]
NASA Aims to Keep Fuel Cool Under Pressure with Zero Boil-Off Experiment On NG-23
Space missions rely on cryogenic fluids — extremely cold liquids like liquid hydrogen and oxygen — for both propulsion and life support systems. These fuels must be kept at ultra-low cryogenic temperatures to remain in liquid form; however, solar heating and other sources of heat increase the rate of evaporation of the liquid and cause […]
