The top-secret Boeing X-37B space plane that has been orbiting the Earth for the last 15 months is scheduled to descend on Vandenberg Air Force Base “during the early- to mid-June timeframe,” according to a statement issued by the base.
The landing will constitute the second for the unmanned spacecraft, following the completion of the first X-37B orbital mission in December 2010. The second X-37B spacecraft, OTV-2, was launched from Cape Canaveral aboard an Atlas V rocket in March 2011 and has remained in orbit ever since.
