SLS hot fire test completes the “Green Run” campaign

The world’s most powerful rocket – NASA’s Space Launch System (SLS) – just completed a successful hot fire test of all four RS-25 engines for 8 minutes and 19 seconds at Stennis Space Center.

The hot fire test is the last checkpoint of the “Green Run” series of eight tests that validate the functionality of the SLS core stage’s flight readiness for the Artemis mission and simulate the duration of a successful launch. Artemis is NASA’s mission to take humans back to the Moon and eventually Mars.

At each stage of the journey from the Earth to the Moon, and back again, SLS is the vehicle that will take human spaceflight into the next generation of deep space exploration.
