BOULDER, Colo. (NASA PR) — A non-toxic, rosé-colored liquid could fuel the future in space and propel missions to the Moon or other worlds. NASA will test the fuel and compatible propulsion system in space for the first time with the Green Propellant Infusion Mission (GPIM), set to launch this month on a SpaceX Falcon Heavy rocket.
