NASA astronaut shows how to 'weigh' yourself in space | On the ISS this week Nov. 17-21, 2025

Lawmakers on Capitol Hill are urging the NASA inspector general to investigate the Goddard Space Flight Center following the closure of essential campus facilities during the government shutdown. This situation has raised concerns about the impact on NASA's operations and research capabilities.

NASA's Artemis 2 mission is progressing as the Orion crew module has been successfully stacked onto the Space Launch System (SLS) in preparation for the upcoming launch scheduled for early 2026. This marks a significant step in NASA's efforts to return humans to the Moon.

NASA has released a new collection of images of the interstellar comet 3I/ATLAS, showcasing its features as it approaches the sun. These images were captured by various spacecraft, including those positioned near Mars, providing a unique perspective on this celestial visitor.

A species of moss survived for 9 months on the exterior of the International Space Station, according to new research. Remarkably, 80% of the samples continued to reproduce after being returned to Earth, demonstrating the resilience of this organism in extreme conditions.

Researchers have discovered that spores of the moss species Physcomitrella patens can survive for at least nine months on the exterior of the International Space Station (ISS) and still reproduce upon returning to Earth. This resilience suggests that mosses could play a role in oxygen generation or soil formation during future space missions, potentially transforming barren landscapes on other planets into fertile ground.

Astronauts attached moss spores to the exterior of the International Space Station (ISS) for a duration of 283 days. Remarkably, most of these spores survived the harsh conditions of space and were able to germinate upon their return to Earth.

NASA has released new images of the interstellar comet 3I/ATLAS, confirming its identity as a comet and dispelling rumors of alien origins. A NASA official emphasized that the interstellar visitor exhibits typical comet characteristics.
