That secretive U.S. Space Force X-37B space plane is now targeted for launch on December 10th. Original launch date was December 7 with the slip “due to launch delays and pad availability,” according to a U.S. Space Force statement.

Final preparations to launch the program’s seventh robotic flight, labeled the X-37B Orbital Test Vehicle (OTV-7), are underway.

This X-37B flight will be the first to launch on a SpaceX Falcon Heavy rocket—designated USSF-52.

Onboard the craft are tests to appraise the vehicle’s operation in new orbital regimes, experimenting with space domain awareness technologies and investigating the radiation effects to NASA materials.
