The second Boeing X-37B OTV (orbital test vehicle) touched down at Vandenberg AFB, Calif., on June 16 after a 469-day mission (USA-226). OTV-2 had launched from Cape Canaveral, Fla., on board an Atlas V launch vehicle on March 5, 2011. The first X-37B mission (USA-212) with OTV-1 was launched on April 22, 2010 and landed on December 3. Thus, the X-37B has now successfully accomplished two automatic recoveries of a vehicle from space. The only time this has been achieved before was the unmanned launch and recovery of the Soviet Buran shuttle in 1988.
