mysterious

The Falcon Heavy lifted off on the clandestine mission at 8:07 PM Eastern from NASA’s Kennedy Space Center. The U.S. Space Force’s X-37B space plane, a reusable vehicle that acts as a classified testbed for experiments in space, was the sole payload on the massive rocket. Even the windows of the small space plane are blacked out. One of the big mysteries of this particular mission is the Space Force’s choice to book a triple-boosted Falcon Heavy. This is the fifth time SpaceX has launched a Falcon Heavy rocket this year, and the ninth overall since 2018.
