FleaPlus writes "The US Air Force has announced that it is developing an unmanned reusable spaceplane, the X-37B Orbital Test Vehicle. The first launch is in 2008 on an Atlas V rocket. The X-37B will be one-fourth the size of the Space Shuttle and serve as a testbed for technologies for future reusable spacecraft. Its predecessor, the X-37, was drop-tested from the Scaled Composites White Knight mothership earlier this year."
