Rocket Belt

a low-power rocket motor used by an astronaut for extravehicular propulsion and maneuvering. It may be manual, in which case the astronaut directs the rocket motor in such a way as to produce the required direction of thrust, or attached to the space suit, in which case the astronaut plugs the supply of the working substance into one or more nozzles, which have various orientations. The working substance is usually compressed gas or a monopropellant.
