NASA successfully test-fired the core stage of its Space Launch System (SLS) rocket for the second time on Thursday afternoon.
The powerful moon rocket’s four RS-25 engines fired for eight minutes and 19 seconds at approximately 4:37 p.m. ET at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
The “Green Run” series hot fire test of the 212-foot-tall core stage marks what NASA says is a “critical milestone” ahead of their future lunar missions.
