X-37B spacecraft returns to Earth after 15-month secret mission
469 days in space spent U.S. spacecraft X-37B . What were you doing? Nobody knows, because it was a secret mission, wrapped in mystery. The ship landed at the weekend at the Vandenberg Air Force Base in California.
The trip was 200 days longer than originally planned, and more than twice longer than the first trip of the X-37B, which lasted 224 days.
Although this ship was originally a NASA project launched in 1999, was transferred in 2004 to the defense agency DARPA. No details of the plane, so speculation about its purpose range from as a vehicle of transport for military applications.
What is clear is that has a great ability to stay in space and return safely to Earth, even 15 months after taking off.DARPA, Mission, plane, secret, U.S., X-37B
