NASA astronaut and Expedition 74 flight engineer Jessica Meir’s reflection is captured in a spacesuit helmet visor. The visor assembly is coated with a microscopic layer of gold that reflects infrared radiation to protect an astronaut’s eyes while allowing visible light to pass through. Meir was working inside the International Space Station’s Quest airlock, installing [...]
NASA/Scott Eckley These X-ray computed tomography (XCT) scans released on March 17, 2026, give us a glimpse inside asteroid Bennu. They show the most common types of crack networks observed in Bennu samples; these networks solved a mystery that baffled NASA for years. When NASA’s OSIRIS-REx spacecraft first approached asteroid Bennu in 2018, scientists expected to see smooth, sandy beach-like surfaces. [...]

They show the most common types of crack networks observed in Bennu samples. Credits: NASA/Scott Eckley In one of the biggest surprises of NASA’s OSIRIS-REx mission, its target asteroid, [...]
The bigger the hailstone, the more damage it can cause. But scientists find that predicting hailstone size can be challenging. How quickly does hail melt as it falls? Now, you can help tackle this question by joining the SouthEAst REgion CoCoRaHS Hail (SEaRCH) project. This network of backyard weather observers includes volunteers of all ages [...]
NASA’s crawler-transporter 2, carrying NASA’s Artemis II SLS (Space Launch System) rocket with the Orion spacecraft, arrives Wednesday, Feb. 25, 2026, inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida to troubleshoot the flow of helium to the rocket’s upper stage, the interim cryogenic propulsion stage. Once complete, the SLS rocket will roll back to Launch Complex 39B to prepare to launch four [...]

Photo of the Day If not perfect, then this spiral galaxy is at least one of the most photogenic. An island universe containing billions of stars and situated about 40 million light-years away toward the constellation of the Dolphinfish (Dorado), NGC 1566 presents a gorgeous face-on view. Classified as a grand design spiral, NGC [...]
