Dream Chaser cargo spacecraft reaction control system is the spacecraft's in-space thruster system. NASA identifies 26 reaction-control-system thrusters, including a combination used to commit the spacecraft to deorbit. Sierra Space describes Dream Chaser's internally developed thrusters as three-thrust-mode units and documents the VRP110-B non-toxic thruster as initially developed for Dream Chaser, using high-test peroxide and kerosene/RP-1.
