Secretive space drone used to test futuristic propulsion system
Ask someone in the street what they know about the Air Force's top-secret space plane and you'll probably wind up getting pinched by the NSA. Nobody can claim to know much about the X-37B, beyond the fact that it's the force's long-term space vehicle, capable of staying in orbit for more than a year at a time. In the run up to the craft's next jaunt around the planet, however, someone has let slip the details of an experiment that it'll be carrying out. According to Spaceflight Now, Air Force officials have revealed that the autonomous drone will be used as the test-bed for a new type of Hall effect thruster.
