LOX/LH2 Reaction Control System

Northrop Grumman is developing a 1000-lbf liquid oxygen/liquid hydrogen Reaction Control System (RCS) thruster for use as on-orbit propulsion to maneuver second-generation launch and space transportation vehicles during payload deployment and docking.

The engine’s non-toxic features reduce hazardous conditions during launch preparation and return operations.  This ease of handling improves efficiency by shortening vehicle turn-around time on the ground between missions.

Initial Testing was conducted at NASA’s Marshall Space Flight Center.
