X-37B
The X-37B is a reusable, uncrewed robotic spaceplane operated by the U.S. Space Force for orbital missions, performing various experiments and technology demonstrations. It can stay in orbit for extended periods, sometimes for over two years, before returning to Earth.

TECHNICAL DEFINITION
The Boeing X-37B Orbital Test Vehicle (OTV) is an autonomous, reusable robotic spaceplane operated by the U.S. Space Force for advanced technology demonstrations, orbital reconnaissance, and payload deployment/retrieval missions, characterized by its long-duration flight capabilities and re-entry/landing functionality.
BACKGROUND
The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. It is boosted into space by a launch vehicle, re-enters Earth's atmosphere, and lands as a spaceplane. The X-37 is operated by the Department of the Air Force Rapid Capabilities Office, in collaboration with the United States Space Force, for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120-percent-scaled derivative of the earlier Boeing X-40. The X-37 began as a NASA project in 1999, before being transferred to the United States Department of Defense in 2004. Until 2019, the program was managed by Air Force Space Command.
