Engineers and technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are putting the Green Propulsion Dual Mode flight hardware through critical pre-launch testing. The mission, a 6-U CubeSat, will demonstrate a first-of-its-kind integrated propulsion system that uses a single, non-toxic "green" propellant called ASCENT to perform both high-thrust and low-thrust maneuvers in space. These behind-the-scenes photos capture the team conducting rigorous physical and environmental tests inside the center’s Small Spacecraft Servicing and Integration Lab to ensure the spacecraft is ready for the extreme environment of low Earth orbit.
