NASA tested RS-25 engine No. 10001 on Oct. 21 on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Test teams fired the developmental engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during launch of NASA’s SLS (Space Launch System) rocket. During
Interstellar probes. Lunar drones. Helicopters on Mars. When a group of Caltech graduate students and enthusiasts began conducting rocket-propulsion tests in Pasadena’s Arroyo Seco on Oct. 31, 1936, they had no idea that their work marked the inception of the Jet Propulsion Laboratory. Ninety years later, the lab, now managed by Caltech for NASA, isn’t
As part of the agency’s Inspiration Tour, NASA will conduct a flyover at the University of Alabama vs. Texas A&M football game in Tuscaloosa, Alabama, on Saturday, Oct. 24. NASA Administrator Jared Isaacman will pilot one of three F-5 fighter jets during the flyover, highlighting NASA’s contributions to aeronautics and the agency’s continued commitment to
