For almost two years, an unmanned space plane bearing a remarkable resemblance to NASA’s space shuttle has circled the Earth, performing a top-secret mission. It’s called the X-37B Orbital Test Vehicle — but that’s pretty much all we know for certain.
Officially, the only role the Pentagon acknowledges is that the space plane is used to conduct experiments on new technologies. Theories about its mission have ranged from an orbiting space bomber to an anti-satellite weapon.
The truth, however, is likely much more obvious: According to intelligence experts and satellite watchers who have closely monitored its orbit, the X-37B is being used to carry secret satellites and classified sensors into space — a little-known role once played by NASA’s new retired space shuttle.
