Measurements from space support wildfire risk predictions

Researchers demonstrated that data from the International Space Station’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument played a significant role in the ability of machine learning algorithms to predict wildfire susceptibility. This result could ( Read more... )

Insights into metal alloy solidification

Researchers report details of phase and structure in the solidification of metal alloys on the International Space Station, including formation of microstructures. Because these microstructures determine a material’s mechanical properties, this work could support improvements in techniques for producing ( Read more... )

NASA astronaut Suni Williams is seen outside the International Space Station during the Jan. 16, 2025, spacewalk where she and fellow NASA astronaut Nick Hague replaced a rate gyro assembly that helps maintain the orientation of the orbital outpost. It was the fourth spacewalk for Hague and the eighth for Williams.

Williams and Hague also installed ( Read more... )

In December 2024, five CubeSats deployed into Earth’s orbit from the International Space Station. Among them was LignoSat, a wooden satellite from JAXA (Japanese Aerospace Exploration Agency) that investigates the use of wood in space. Findings could offer a more sustainable alternative to conventional satellites.

A previous experiment aboard ( Read more... )

Decompression sickness (DCS) is a condition which results from dissolved gases (primarily nitrogen) forming bubbles in the bloodstream and tissues. It is usually experienced in conditions where there are rapid decreases in ambient pressure, such as in scuba divers, high-altitude aviation, or other pressurized environments. The evolved gas bubbles ( Read more... )

With more than 25 years of operations, the International Space Station continues to symbolize discovery and cooperation for the benefit of humanity. Since 2012, observers have interacted with the space station through NASA’s Spot the Station website, a web browser-based tool that includes interactive maps for users to track the station and find ( Read more... )
