Suni Williams Conducts Spacewalk
NASA 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 [...]
Station Science Top News: Jan. 17, 2025
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 [...]

The fourth planet from the Sun is reminiscent of a rich, red desert and features a rugged surface challenging to traverse. [...]
Comet ATLAS over Brasília
Photo of the Day What's that in the sky? Above the city, above most clouds, far in the distance: it's a comet. Pictured, the impressive tail of Comet C/2024 G3 (ATLAS) was imaged from Brasília, Brazil four days ago. Last week the evolving comet rounded the Sun well inside the orbit of planet Mercury, [...]
Comet ATLAS Rounds the Sun
Photo of the Day Why does Comet ATLAS have such colorful tails? Last week Comet C/2024 G3 (ATLAS) passed its closest to the Sun -- well inside the orbit of Mercury -- and brightened dramatically. Unfortunately, the comet was then so angularly near the Sun that it was very hard for humans to see. [...]
Titan Touchdown: Huygens Descent Movie
Photo of the Day What would it look like to land on Saturn's moon Titan? The European Space Agency's Huygens probe set down on the Solar System's cloudiest moon in 2005, and a time-lapse video of its descent images was created. Huygens separated from the robotic Cassini spacecraft soon after it achieved orbit around [...]
Post-Spacewalk Cleanup, Physics and Biology Research Wrap Up Week
Astronaut Suni Williams is pictured during a spacewalk outside the space station where she replaced a rate gyro assembly that helps maintain the orientation of the orbital outpost on Jan. 16, 2025. Two NASA astronauts took a half-a-day off on Friday following a spacewalk the previous day then cleaned up spacesuit gear and held a [...]
