A SpaceX Falcon Heavy rocket lifts off from Launch Complex 39A at 2:30 a.m. EDT on June 25, 2019, at NASA’s Kennedy Space Center in Florida. The Falcon Heavy rocket carries two dozen satellites to space for the U.S. Department of Defense, including four NASA payloads that are part of the Space Test Program (STP-2) mission, managed by the U.S. Air Force Space and Missile Systems Center. The four NASA payloads include two technology demonstrations to improve how spacecraft propel and navigate, as well as two NASA science missions to help us better understand the nature of space and how it impacts technology on spacecraft and the ground.
