NASA to Demonstrate New “Green” Propellant in Space Using Aerojet Rocketdyne Propulsion System
Green Propellant Infusion Mission(GPIM) will demonstrate in space for the first time a new non-toxic propellant offering nearly 50% higher performance over traditional monopropellant fuel
- Aerojet Rocketdyne’s specially-engineered propulsion system for the “green” propellant, called AF-M315E, is the sole means of onboard propulsion for the spacecraft
- AF-M315E has a higher performance level and other operational advantages, making it a viable fuel option for various next-generation spacecraft
Powered by this green propellant, Aerojet Rocketdyne’s green propellant propulsion system will enable the spacecraft to execute and demonstrate orbital maneuvers in space. The system includes five 1-newton thrusters: four for attitude control and one for orbit maneuvering. This will be the first space-based demonstration of Aerojet Rocketdyne’s green propulsion technology utilizing AF-M315E propellant.
“Aerojet Rocketdyne has provided trusted and reliable in-space propulsion to industry, government and commercial partners since the beginning of the space age,” said
AF-M315E is a higher performance and environmentally-friendly alternative for chemical propulsion operations that traditionally use hydrazine. Because of its increased density and higher performance, satellites can achieve extended operation timelines and increased maneuverability. Its lower freezing point eliminates the need for added onboard heating systems, resulting in a greater mass allowance for added life. Green propellant is also non-toxic, which enables safe handling of the propellant and simplifies pre-launch processing.
