This video is a compilation of military experts speculating on the X-37B space plane.
The X-37B, a classified reusable space plane being developed by the U.S. Air Force, has broken its own record for endurance. This week it surpassed the previous mission of 469 days in orbit.
Skywatcher Kevin Fetter of Brockville, Ontario in Canada shot this March 9, 2014 video of the U.S. military's X-37B space plane passing by the moon. The robotic US Air Force space plane surpassed 470 days in orbit, an endurance record, in March 2014.
The X-37B Orbital Test Vehicle mission 3 (OTV-3), the Air Force's unmanned, reusable space plane, landed at Vandenberg Air Force Base at 9:24 a.m. Oct. 17 .

The X-37B is scheduled to lift off atop a United Launch Alliance Atlas V rocket from Florida's Cape Canaveral Air Force Station in May 2020.
A United Launch Alliance (ULA) Atlas V 501 rocket launched the USSF-7 mission for the U.S. Space Force, the sixth flight of the X-37B Orbital Test Vehicle (OTV-6), from Space Launch Complex 41 at Cape Canaveral Air Force Station, Florida, on 17 May 2020, at 13:14 UTC (09:14 EDT). Built by Boeing, X-37B Orbital Test Vehicle (OTV) is a reusable unmanned spacecraft. The mission was the 84th for an Atlas V launch vehicle and the 7th in the 501 configuration.

The X-37B just launched on its sixth classified mission to space for the US Air Force. We run down what details we do know about the experiments it will be running.
According to the U.S. Space Force, the Boeing X-37B Orbital Test Vehicle landed at Vandenberg Space Force Base, California, on 7 March 2025, at 07:22 UTC (02:22 EST; 6 March, at 23:22 local time), ending its seventh mission (OTV-7/USSF-52) after over 434 days in space. During the mission, X-37B executed “a series of novel maneuvers, called aerobraking, to change its orbit around Earth and safely dispose of its service module components”.
A SpaceX Falcon 9 launch vehicle launched USSF-36, the eighth launch of the Boeing X-37B Orbital Test Vehicle (OTV-8), from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center, Florida, on 22 August 2025, at 03:50 UTC (21 August, at 23:50 EDT). Following stage separation, Falcon 9’s first stage landed on SpaceX’s Landing Zone 2 (LZ-2) at Cape Canaveral Space Force Station, Florida. Falcon 9’s first stage (B1092) previously supported 5 missions: CRS-32, NROL-69, GPS III SV07 and 2 Starlink missions.
