Green Propellant Infusion Mission (GPIM) Overview
GPIM launched to low-Earth orbit June 25, 2019, aboard a SpaceX Falcon Heavy rocket.
The technology demonstration mission seeks to improve overall propellant efficiency, while reducing the handling concerns associated with the toxic fuel hydrazine. GPIM also strives to optimize performance of new hardware, systems and power solutions while ensuring the best value for investment and the safest space missions possible.
Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system.
The Green Propellant Infusion Mission (GPIM)—which consists of a non-toxic liquid, compatible propulsion system and the small satellite it’s riding on—will demonstrate how our technology works so that future missions can take advantage of this safer, more efficient fuel alternative.
Through the Green Propellant Infusion Mission, or “GPIM” project, NASA is developing a “green” alternative to conventional chemical propulsion systems for next-generation launch vehicles and spacecraft.
Satellites love hydrazine – a type of space propellant – but it’s toxic to people and extremely difficult to handle. A non-toxic alternative will be put to the test with NASA’s Green Propellant Infusion Mission (GPIM), set to launch on a SpaceX Falcon Heavy rocket.
