Green Run Update: NASA TV Coverage Underway for Hot Fire Test

Countdown is continuing for the hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket. The test is expected to start soon and last about 8 minutes to simulate launch and ascent of the SLS to orbit.

NASA Television coverage has begun. Watch live:

Teams powered up the core stage’s avionics systems Tuesday, Mar. 16, and began the countdown for the hot fire test earlier today. The team is continuing to closely monitor core stage and facility performance before proceeding into the final phase of the test: the terminal countdown leading to the hot fire.

During this test, the team has repeated many of the major milestones marked during the wet dress rehearsal and the first hot fire test, including chilling the main propulsion system and completely filling both propellant tanks. Coming up at 10 minutes before the test, the test conductor will poll the team who will give the final “go/no go” to proceed with the hot fire test.
