arshadk writes with this excerpt from Wired's Danger Room: "The X-37B has generated intense interest, long before it ever left the ground. Boeing originally developed the 29-foot unmanned craft — a kind of miniature Space Shuttle — for NASA. Then, the military took over in 2004, and the space plane went black. Its payloads were classified, its missions hush-hush. ... You can even see the space plane for yourself: The X-37B is traveling in a slightly elliptical orbit more than 200 miles up, swooping from 43 degrees north latitude to 43 degrees south."
