Originally designed for military applications, NASA’s mine-resistant ambush protected vehicles, or MRAPs, will be used in the unlikely event of an emergency at the launch pad prior to liftoff. The vehicles, seen here during a Boeing/United Launch Alliance emergency egress system demonstration at Cape Canaveral Air Force Station’s Launch Complex 41 in Florida on June 19, 2018, offer a mobile bunker for astronauts and ground crews, should they need to get away from the launch pad quickly in an emergency.
