The mission, dubbed USSF-124, was the eighth National Security Space Launch using a SpaceX Falcon 9 rocket. Liftoff occurred at the start of a four-hour launch window that opened at 5:30 p.m. EST (2230 UTC) on Wednesday.
Falcon Heavy is returning to the hangar and the launch of the USSF-52 mission with the X-37B spaceplane is on hold. A ground issue scrubbed an earlier launch attempt and now required work on the vehicle itself.
The U.S. military’s experimental spaceplane will soon soar to orbit using a SpaceX Falcon Heavy rocket for the first time, a Pentagon news release announced. The X-37B spacecraft will launch from the Kennedy Space Center no earlier than December 7.
