Aboard a SpaceX Falcon Heavy rocket, the seventh (acknowledged) mission of the Pentagon’s X-37B, an uncrewed satellite that resembles a miniature space shuttle without windows. According to CNN, the X-37B will continue to conduct tests, but at a higher orbital distance thanks to the power of the Falcon Heavy.
Known as an Orbital Test Vehicle, the X-37B has been the subject of much speculation and conspiracy theories. First launched into orbit in 2010, the reusable autonomous vehicle stayed in orbit for over two years on one mission. Conspiracy theorists believe the craft is a space bomber that can release deadly kinetic missiles that can destroy entire cities or that it is a floating spy platform keeping an eye on the Chinese space station.
