SLS Update: The Second Green Run Hot Fire Test Is Now Scheduled to Take Place on March 18...

Atop the B-2 Test Stand at NASA's Stennis Space Center near Bay St. Louis, Mississippi, the Space Launch System's four RS-25 engines fire for 67 seconds (out of a planned 485 seconds) before shutting down during the first Green Run hot fire test...on January 16, 2021.

NASA announced today that it is aiming for Thursday, March 18, to conduct the second and hopefully final Green Run hot fire test of the Space Launch System's core stage booster that will fly on the Artemis 1 mission no earlier than February of 2022. The new test date was revealed after the space agency felt comfortable that the faulty liquid oxygen pre-valve which thwarted the February 25 hot fire attempt was successfully repaired.
