NASA Fires Up RS-25 Artemis Moon Rocket Engine Test For 500 Seconds

NASA fired up RS-25 engine No. 20001 at the Fred Haise Test Stand at NASA’s Stennis Space Center at Bay St. Louis, Mississippi.

The test lasted about "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," according to NASA.
