Artemis III Cryo Sim in LCC Firing Rooms 1 and 2
Artemis III launch team members participate in a cryogenic propellant loading simulation on Wednesday, Oct. 14, 2026, inside Firing Rooms 1 and 2 of the Rocco A. Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida. Members of NASA’s Exploration Ground Systems team rehearse the steps to load the super-cooled liquid hydrogen and liquid oxygen into the SLS (Space Launch System) rocket core stage, a process that starts several hours before liftoff for the Artemis III mission. Artemis III will carry out a series of objectives in low Earth orbit designed to demonstrate critical systems needed for future lunar landings, beginning with Artemis IV.
