EVA rig

An EVA rig is an astronaut propulsion unit designed to propel and maneuver an astronaut through open space during a spacewalk. It consists of a back-mounted propulsion pack built into a harness worn over a spacesuit, with various maneuvering thrusters positioned across the harness to provide a full range of directional thrust.

During their escape from the debris field created by the destruction of the Chandrakanta, Maya Prasad and Maureen Conover were able to use their EVA rigs to propel both themselves and the Chandrakanta's severed airlock chamber through the debris field and into docking position with with the pirate Bowhead vessel that had destroyed their ship. Their EVA rigs provided enough thrust and maneuverability to match speed with the cruising Bowhead long enough to dock with it despite carrying two tons of extra weight in the form of the airlock chamber, although the act of doing so quickly depleted their fuel tanks.
