September 25th, 2025 14:00:03 EDT -0400 NASA, Sierra Space Modify Commercial Resupply Services Contract
In 2016, NASA awarded a Commercial Resupply Services-2 contract to Sierra Space, formerly part of Sierra Nevada Corporation, to resupply the International Space Station with its Dream Chaser spaceplane and companion Shooting Star cargo module. As part of its contract, Sierra Space was awarded a minimum seven flights, and the agency previously issued firm-fixed price task orders for […]
September 25th, 2025 12:07:08 EDT -0400 NASA Astronaut Chris Williams to Discuss Upcoming Launch, Mission
NASA will host a news conference at 2 p.m. EDT Wednesday, Oct. 1, from the agency’s Johnson Space Center in Houston to highlight the upcoming mission of astronaut Chris Williams to the International Space Station. The news conference will stream live on NASA’s website and YouTube channel. Learn how to watch NASA content through a […]
September 24th, 2025 15:12:18 EDT -0400 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 […]
September 18th, 2025 12:14:05 EDT -0400 Milky Way Views
The Milky Way appears above Earth’s bright atmospheric glow in this Aug. 23, 2025, photograph from the International Space Station as it soared 261 miles above southern Iran at approximately 12:54 a.m. local time. The camera was configured for low light and long duration settings. Our home galaxy has hundreds of billions of stars, enough […]
September 17th, 2025 11:35:02 EDT -0400 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 […]

September 10th, 2025 11:04:26 EDT -0400 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 […]
September 9th, 2025 06:00:00 EDT -0400 Life After Microgravity: Astronauts Reflect on Post-Flight Recovery 
Space changes you. It strengthens some muscles, weakens others, shifts fluids within your body, and realigns your sense of balance. NASA’s Human Research Program works to understand—and sometimes even counter—those changes so astronauts can thrive on future deep space missions.   Astronauts aboard the International Space Station work out roughly two hours a day to protect […]
