ABOUT REACTION CONTROL SYSTEM (DRAGON)
The Dragon 2 Reaction Control System uses 16 Draco thrusters arranged around the spacecraft trunk and capsule for attitude control and orbital maneuvering. Each thruster produces 400 N of thrust using NTO/MMH hypergolic propellant. The system handles on-orbit attitude, deorbit burns, and reentry orientation.
