Spacecraft Powered by 'Green' Propellant to Launch in 2017

A spacecraft that will test the unique attributes of a high-performance, nontoxic, "green" fuel on orbit is being prepped for launch in 2017. NASA's Green Propellant Infusion Mission (GPIM) is set to blast off from Florida's Cape Canaveral Air Force Station next year aboard SpaceX's Falcon Heavy rocket. The launch is part of the Air Force's Space Test Program 2 (STP-2) mission.
