The Green Propellant Infusion Mission has fired its five thrusters.The future of space travel is looking green.
Less than a week after launching on a SpaceX Falcon Heavy rocket on June 25, NASA's Green Propellant Infusion Mission (GPIM) has passed its first test, successfully firing its five thrusters. The GPIM is powered by a new "green" fuel that NASA hopes can replace hydrazine, a toxic substance that is currently used by most spacecraft. The new fuel is low toxicity, making it better for both the environment and the humans who have to work with the stuff in preparation for a launch.
The mission's thrusters fired in order to briefly lower the spacecraft's orbit as part of its "checkout" phase, during which operators verified that systems were working as expected after launch.
