Astronauts are scheduled to venture outside the International Space Station to collect microbiological samples during crew spacewalks for the ISS External Microorganisms experiment. This investigation focuses on sampling at sites near life support system vents to examine whether the spacecraft releases microorganisms, how many, and how far they may travel. This experiment could help researchers […]...
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 […]...
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 coatings and additive manufacturing or 3D printing processes. METCOMP, an ESA […]...
