A mysterious space craft built and launched by the US Air Force has now spent roughly a year in orbit around Earth - though no one knows what it's doing there.
The X37-B spy plane is an unmanned drone similar in outward appearance to the Space Shuttle, though much smaller and without the capacity to carry astronauts.
The 11,000-pound craft is only 29 feet long, 15 wide and about a quarter of the size of the now-retired Space Shuttle.
