Description

Along with its sleek design, the gravity-mapping GOCE mission achieved drag-free flight with an electric ion propulsion system mounted at the back of the satellite. Unlike conventional engines, it used electrically-charged xenon to create a gentle thrust. The system continually generated tiny forces to counteract the drag the satellite experienced as it cut through the remnants of Earth’s atmosphere.
