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 […]

From orbit, today’s space-based laser instruments measure Earth’s forests and terrain one narrow line at a time. Between those lines are enormous gaps that include millions of acres of land scientists never directly measure. NASA’s CASALS instrument will blend machine learning with an ultra-compact lidar instrument to adaptively ‘sweep’ large swaths of Earth’s surface. This […]
