DARPA Space Plane May Reach Speeds In Excess Of Mach 10

DARPA has selected three awardees of $6.5 million each to develop and design the concept of a space plane that will be able to send small spacecraft in orbit, fly at Mach 10 speed, return to Earth and go back to space repeatedly, while costing less than $5 million each flight. Designs should be completed a year from now, and a prototype should be sent to space in 2018.
