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.
