The U.S. Space Force’s shadowy X-37B spaceplane is set to launch atop a SpaceX Falcon Heavy rocket on Dec. 7. It’ll mark the seventh mission for the X-37B, but the first time it’ll fly on a heavy-lift launcher. Space.com reports: Little is known about the capabilities and operations of the space plane, but Space Force says the mission will follow previous flights that used the X-37B as a test bed for launching experimental payloads and returning them to Earth. “We are excited to expand the envelope of the reusable X-37B’s capabilities, using the flight-proven service module and Falcon Heavy rocket to fly multiple cutting-edge experiments for the Department of the Air Force and its partners,” said Lt. Col. Joseph Fritschen, program director for the X-37B, in the statement.
It isn’t known why the X-37B is launching atop a Falcon Heavy for the USSF-52 mission. Five of the space plane’s previous missions launched on United Launch Alliance Atlas V rockets, while its fifth mission, USA-277, took off on top of SpaceX’s smaller rocket, the Falcon 9 (Falcon Heavy consists of three Falcon 9 boosters strapped together). Such a change could suggest that the space plane is carrying heavier payloads or is sporting a new hardware configuration. So far, Space Force has only stated that the mission will “expand the United States Space Force’s knowledge of the space environment by experimenting with future space domain awareness technologies,” according to the statement. However, Space Force’s statement adds that the mission will carry a NASA experiment known as Seeds-2 that will test the effects that space-based radiation has on plant seeds during a long-duration spaceflight.
