Potential future uses of hybrid rockets include launching satellites, especially nanosatellites, into space from Earth. Such systems also could be very useful in situations where high thrust is required to lift heavy payloads loads into space from planetary surfaces, such as NASA’s planned Mars Ascent mission.
