The U.S. Air Force's robotic X-37B space plane finally returned to Earth Saturday, wrapping up a mysterious mission that lasted more than year in orbit.
The unmanned X-37B spacecraft, also known as Orbital Test Vehicle-2 (OTV-2), glided back to Earth on autopilot, touching down at California's Vandenberg Air Force Base at 5:48 a.m. PDT (8:48 a.m. EDT, 1248 GMT). The landing brought to an end the X-37B program's second-ever spaceflight, a mission that lasted more than 15 months with objectives that remain shrouded in secrecy.
Air Force officials announced the X-37B space plane's successful landing in a brief statement posted on the Vandenberg website and emailed to reporters.
