Mission Details

OTV-6 (X-37B)

The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable uncrewed spacecraft. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the United States Air Force for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120%-scaled derivative of the earlier Boeing X-40.

The spacecraft successfully landed at the KSC Shuttle Landing Facility on November 12, 2022, at 5:22 AM EST, 10:22 AM UTC. The spacecraft spent 908 days in orbit, its longest flight yet.
