NASA Improves Shock, Vibration Analysis
Rockets vibrate, shake, and flex intensely as they climb into space, and spacecraft packed with delicate scientific instruments must survive those forces. Before any rocket leaves the ground, NASA engineers work to predict how those stresses will affect every part of a spacecraft. To do that, engineers in the Dynamic Environments Group with NASA’s Launch […]

Why calling for a ‘kill switch’ is the wrong way to think about reining in AI
A kill switch to shut down dangerous AI systems is a seductive concept, but the metaphor hides how the models work – and how they get out of control in the first place.

Artemis II Heat Shield After Splashdown
Shortly after NASA’s Artemis II mission splashed down on April 10, 2026, U.S. Navy divers captured underwater imagery of the Orion spacecraft’s heat shield. In the months after, the agency measured whether the thermal protection system effectively safeguarded the crew and Orion systems as the spacecraft reentered Earth’s atmosphere. This rigorous analysis confirmed that the […]
