NASA Tests New RS-25 Engine
NASA tested RS-25 engine No. 20001 on June 20, at the Fred Haise Test Stand at NASA’s Stennis Space Center at Bay St. Louis, Mississippi. Test teams fired the engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during a launch of an SLS (Space Launch System) rocket on Artemis missions to the Moon. The Artemis campaign will explore the…
