Pathfinder Technology Demonstrator-1 Mission to Demonstrate Green Propulsion System

NASA’s Pathfinder Technology Demonstrator (PTD) project will test the operation of a variety of novel CubeSat technologies in low-Earth orbit, providing significant enhancements to the performance of these small and effec¬tive spacecraft. The PTD-1 mission currently under develop¬ment and slated for launch in 2019, will dem¬onstrate a propulsion system with a water-based propellant. While in orbit, the system separates onboard water into hydrogen and oxygen propellants by applying an electric current through the water. The propulsion system uses the on-orbit power provided by the arrays to power the miniature water elec¬trolysis system. The demonstration will test propulsion performance through programmed changes in spacecraft velocity and altitude executed by the water-fueled thrusters. The PTD series of missions is managed and funded by the Small Spacecraft Technology (SST) pro¬gram within the Space Technology Mission Directorate at NASA Headquarters.
