NASA's Second Hot Fire Test for the Artemis Moon Rocket

We are targeting 3:45 p.m. EDT on Thursday, March 18 for the second hot fire test of the core stage for the Space Launch System rocket at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Engineers will power up all the core stage systems, load more than 700,000 gallons of supercold propellant into the tanks, and fire the rocket’s four RS-25 engines at the same time to simulate the stage’s operation during the launch of our first Artemis mission to the Moon.
