gpim-newton-hotfire-4

On June 3, members of the Green Propellant Infusion Mission (GPIM) project completed the fourth hot-fire acceptance test on a 1 Newton thruster at Aeroject Rocketdyne’s Facility in Redmond, Washington. NASA is looking for ways to replace hydrazine with a more environmentally friendly fuel and thrusters propelled by this green propellants formulation could provide better performance without all the toxic chemical characteristics. GPIM is developing a high-performance, high-efficiency alternative to conventional chemical propulsion systems for next-generation spacecraft.
