[Via Satellite 12-31-2015] NASA has selected Aerojet Rocketdyne for a public-private partnership to mature the design of the 1-Newton GR-1 monopropellant thruster, which uses a green propellant known as AF-M315E. Once matured, the improved GR-1 thruster will enable the technology to transition from development to production for commercial and government customers, using a green propellant that provides a safer, more efficient and higher-performance alternative than traditional hydrazine propellants.
The 1-Newton GR-1 is a small rocket engine used for attitude, trajectory and orbit control of small and medium-sized satellites and spacecraft. Under the partnership, Aerojet Rocketdyne will deliver for development and validation testing a fully integrated 1-Newton GR-1 thruster that uses AF-M315E propellant. In return, NASA will test the thruster at NASA Glenn Research Center; NASA’s Goddard Space Flight Center will oversee test planning and ensure infusion of the green technology on future NASA missions.
Aerojet Rocketdyne was selected for this project under NASA’s “Utilizing Public-Private Partnerships to Advance Emerging Space Technology System Capabilities” solicitation, which seeks to develop space technologies that can enhance commercial space and benefit future NASA missions.
