Power and Propulsion Element

Target entity: Power and Propulsion Element
Context triple: [Lunar Gateway, module, Power and Propulsion Element]

• A. CE-20 cryogenic engine
  The CE-20 cryogenic engine is an Indian-developed, liquid hydrogen–liquid oxygen rocket engine that powers the upper stage of ISRO’s heaviest launch vehicles for placing large payloads into orbit.
• B. Orbital Maneuvering System
  The Orbital Maneuvering System was the Space Shuttle’s pair of rear-mounted rocket engines used for orbital insertion, adjustment, and deorbit burns.
• C. Service Propulsion System
  The Service Propulsion System was the main rocket engine of the Apollo Service Module, used for major course corrections, lunar orbit insertion, and trans-Earth injection during Apollo missions.
• D. Draco thrusters
  Draco thrusters are small hypergolic rocket engines developed by SpaceX to provide attitude control and orbital maneuvering for its spacecraft.
• E. RS-68 engine
  The RS-68 engine is a powerful liquid-fueled rocket engine used primarily on the Delta IV launch vehicle, known for its high thrust and simplified design for cost-effective heavy-lift missions.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
