From left, Charlie Blackwell-Thompson, Artemis launch director with NASA’s Exploration Ground Systems Program, and Artemis II pilot Victor Glover participate in training at Launch Complex 39B at the agency’s Kennedy Space Center in Florida on Tuesday, May 6, 2025. Glover and fellow Artemis II crew members and backup members trained with the mine-resistant ambush protected vehicles, or MRAPs, inside the launch pad area. 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.
