Planning crewed missions to the Moon and Mars involves preparing for the medical realities of long-duration space travel. Factors like cosmic radiation, microgravity, and distance from Earth create unique health considerations for astronauts. To anticipate these needs ahead of time, NASA developed the Integrated Medical Model (IMM). The IMM is a decision-support tool that uses […]

Summer Training: Catching Up With NASA’s Astronaut Candidates
Did you spend part of your summer camping, hiking, at the pool, or in an aircraft? So did NASA’s 2025 Astronaut Candidate Class. The 10 candidates have been working their way through a comprehensive and rigorous training program since the agency introduced them to the public on Sept. 22, 2025, from NASA’s Johnson Space Center […]
NASA Astronaut Jonny Kim Departs Agency to Continue Military Service
After nearly a decade of service to NASA, including an eight-month science expedition aboard the International Space Station, astronaut Jonny Kim’s last day at the agency is Thursday. He will continue serving as lieutenant commander in the U.S. Navy. Kim launched to the space station in April 2025 aboard the Soyuz MS‑27 spacecraft to conduct […]
NASA Johnson Pilots Chase Moon’s Shadow for Eclipse Science
During the Aug. 12 total solar eclipse over Europe, scientists aimed to study a long-standing mystery: why the Sun’s outer atmosphere, the corona, is far hotter than its visible surface. Capturing the data they needed meant being in exactly the right place at exactly the right time. Pilots from NASA’s Johnson Space Center flew the WB-57F high altitude research aircraft from Ellington Field in Houston to Iceland, […]
NASA Sets Spacewalk for Station Maintenance, Live Coverage Planned
NASA will provide coverage as two astronauts step outside the International Space Station on Tuesday, Sept. 1, to replace a spacecraft navigational aid and complete several maintenance tasks in support of space station operations. Watch live coverage beginning at 7 a.m. EDT. The spacewalk is expected to start at approximately 8:30 a.m. and last about […]

NASA Challenge Tests Wheel Designs for Moon Base Mobility
As NASA prepares to establish the Moon Base, advancing surface mobility will be key to helping crews and robotic systems travel farther across the lunar surface. To help advance that capability, the Rock and Roll with NASA Challenge invited public innovators to design and build next-generation lunar rover wheels. Five teams from 128 submissions and 49 countries advanced to the final phase of the […]
