Crew members and backup members for NASA’s Artemis II mission and teams from the agency’s Exploration Ground Systems Program participate in emergency egress training at Launch Complex 39B at NASA’s Kennedy Space Center in Florida on Tuesday, May 6, 2025. Teams trained with the mine-resistant ambush protected vehicles, or MRAPs, inside the launch pad terminus area, where the emergency egress baskets carrying the astronauts and flight crew will arrive following their safe exit from the mobile launcher. Originally designed for military applications, the 45,000-pound MRAP offers a mobile bunker for astronauts and ground crews in the unlikely event they must get away from the launch pad quickly in an emergency.

Teams from NASA’s Exploration Ground Systems transport the engine section of the agency’s Artemis IV SLS (Space Launch System) core stage from the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida to the spaceport’s Space Systems Processing Facility (SSPF) on Tuesday, Oct. 15, 2024. NASA’s Pegasus barge delivered the core stage engine section housing the four RS-25 engines from NASA’s Michoud Assembly Facility in New Orleans, Louisiana to NASA Kennedy on Thursday, Sept. 5, 2024. The engine section is one the most complex and intricate parts of the rocket stage that will help power the Artemis missions to the Moon.

NASA’s Artemis II hardware, the launch vehicle stage adapter, is inside High Bay 4 on Thursday, March 20, 2025, at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida ahead of rocket stacking operations. The cone shaped launch vehicle stage adapter connects the SLS (Space Launch System) Moon rocket to the upper stage, the interim cryogenic propulsion stage, and protects the rocket’s flight computers, avionics, and electrical devices during launch and ascent during the Artemis missions.
