“The Pentagon wants to cut the costs of putting satellites into space by creating a “space plane” that can fly into low Earth orbit and release satellites for about $5 million a launch,” USA Today reports.

“Called the XS-1, the plane to be developed by the Defense Advanced Research Projects Agency (DARPA) would be capable of flying 10 times the speed of sound (Mach 10), and carry payloads between 3,000 and 5,000 pounds into orbit, according to documents released this week.”
