The US Air Force’s X-37B Orbital Test vehicle has now been in space for more than a year. Little is known about its classified duties, other than that it has a pickup truck-sized payload bay and that stargazers have observed it periodically changing orbits.
Possible uses for the pilot-less space plane could be ferrying supplies to the International Space Station or spying on other countries’ spacecraft. The X-37B was launched on March 5, 2011.
