NASA completes 500-second engine test
NASA says it tested RS-25 developmental engine No. 10001 on October 21 at the Fred Haise Test Stand at Stennis Space Center, near Bay St. Louis, Mississippi. The ground firing lasted 500 seconds, or almost eight and a half minutes.
According to NASA, that duration matches the firing time for RS-25 engines during a Space Launch System rocket launch. The agency said the test supported future Artemis missions.
