SpaceX is set to launch the US military's secretive X-37B spaceplane on its longest-ever flight from the Kennedy Space Center in Florida. The X-37B, a reusable spaceplane, will deploy new experiments and operate in new orbital regimes during the mission. This seventh flight aims to reach higher altitudes and longer flight durations, adding to the X-37B's already impressive flight time of over 3,770 days in space.
