VANDENBERG AIR FORCE BASE, Calif., June 15 (UPI) -- A U.S. Air Force space plane in orbit for more than a year will come back to Earth this weekend, say officials who remained mum on the mission's purpose.
The robotic X-37B, after 15 months in space, is set to land Saturday at California's Vandenberg Air Force Base, although weather and other factors could change that, officials said.
