Draco (rocket Engine)
A Draco thruster is a small hypergolic rocket engine designed by SpaceX for use on their Dragon spacecraft, and on the upper stages of their Falcon 9 and Falcon Heavy rockets, to provide for spacecraft attitude control in the vacuum of space.
SuperDraco rocket engines utilize the same storable (non-cryogenic) propellant as the small Draco thrusters, but are over 100 times larger in terms of delivered thrust. The much larger Super Draco engines will be used on later versions of the Dragon spacecraft to provide launch-escape capability on crew transport flights to low-Earth orbit, as well as entry, descent and landing control of the proposed Red Dragon robotic probe to Mars.
