The U.S. Air Force’s secretive X-37B space plane returned to Earth on Sunday after completing more than two years in orbit.
The uncrewed X-37B Orbital Test Vehicle Mission 5 landed at NASA’s Kennedy Space Center Shuttle Landing Facility at 3:51 a.m. ET Sunday, the Air Force confirmed. The 780-day mission shattered the spaceplane’s own record of almost 718 days in orbit, which was set by Mission 4 when it returned to Earth in May 2017, Space.com reported.
