You would think that an unpiloted space plane built to rocket spaceward from Florida atop an Atlas booster, circle the planet for an extended time, then land on autopilot on a California runway would be big news. But for the U.S. Air Force X-37B project - seemingly, mum's the word. There is an air of vagueness regarding next year's Atlas Evolved Expendable launch of the unpiloted, reusable military space plane. This Boeing Phantom Works craft has been under development for years. Several agencies have been involved in the effort, NASA as well as the Defense Advanced Projects Research Agency (DARPA) and various arms of the U.S. Air Force. The tight-lipped factor surrounding the space plane, its mission, and who is in charge is curious. Such a hush-hush factor seems to mimic in pattern that mystery communications spacecraft lofted last month aboard an Atlas 5 rocket, simply called PAN. Its assignment and what agency owns it remains undisclosed. The problem with it [X37-B] is whether you see it as a weapons platform," said Theresa Hitchens, former head of the Center for Defense Information's Space Security Program, now Director of the United Nations Institute for Disarmament Research (UNIDIR) in Geneva, Switzerland. "It then becomes, if I am not mistaken, a Global Strike platform. There are a lot of reasons to be concerned about Global Strike as a concept," Hitchens [said].
