NASA just validated a new type of propellant, or fuel, for spacecraft of all sizes. Instead of toxic hydrazine, space missions can use a less toxic, “green” propellant and the compatible technologies designed to go along with it. In a little over a year since launch, NASA’s Green Propellant Infusion Mission (GPIM) successfully proved a never-before-used propellant and propulsion system work as intended, demonstrating both are practical options for future missions.
