US has launched another of its kind, a top secret small unmanned shuttle mission into space yesterday. US air force has said nothing about it. The shuttle can land back on any run way after completion of its mission.

Previous shuttle of such kind was X-37B space plane, which circled the planet for seven months in 2010. A second X-37B spacecraft will spent more than a year in orbit.
These high-tech mystery machines - 8 meters long - are about one-quarter the size of the U.S. space agency's old space shuttles and can land automatically on a runway.
