Tissue chips flown to model astronaut organ responses on the ISS Micro-scale tissue chips are being flown to the International Space Station to act as surrogates for human organs, enabling controlled study of cellular and tissue responses to microgravity and space radiation. Data will inform crew medical care and countermeasures for long-duration missions.

The Post‑ISS Era: Commercial and National Stations Set to Redefine LEO Research, Commerce and Security NASA's International Space Station is slated to retire in 2030, and a mix of national successors, agency programs and commercial platforms aim to replace it. Multiple orbiting outposts will reshape research, manufacturing and logistics — and raise traffic, debris and security coordination challenges.

Goddard at 100: 'Nell', a two‑second launch that began modern rocketry On March 16, 1926, Robert H. Goddard’s liquid‑oxygen/gasoline rocket “Nell” lifted off from an Auburn, Massachusetts cabbage patch and flew for roughly two seconds. A century later, the rocket’s fragments, legacy and its line to satellites, Moon missions and commercial rockets are being reexamined.

JWST reveals widespread carbon dioxide on Europa, pointing to ocean–surface exchange James Webb Space Telescope spectra show carbon dioxide is far more widespread on Europa's surface than previously recognized, appearing in lens-like patches across multiple geologic terrains. The distribution implies active exchange processes between the moon's subsurface ocean and the ice shell, reshaping habitability assessments and mission targets.
