NEXT-C ion thruster

Target entity: NEXT-C ion thruster
Context triple: [DART spacecraft, propulsion, NEXT-C ion thruster]

• A. Hall-effect thrusters
  Hall-effect thrusters are a type of electric propulsion system for spacecraft that use magnetic and electric fields to accelerate ions and produce efficient, low-thrust propulsion for orbital maneuvers and deep-space missions.
• B. 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.
• C. Interim Cryogenic Propulsion Stage
  The Interim Cryogenic Propulsion Stage is a liquid hydrogen–liquid oxygen upper stage used on early NASA Space Launch System missions to provide orbital insertion and translunar injection capability before the introduction of a more powerful exploration upper stage.
• D. Service Propulsion System (SPS)
  The Service Propulsion System (SPS) was the main liquid-fueled rocket engine of the Apollo Service Module, used for major course corrections, lunar orbit insertion, and trans-Earth injection during Apollo missions.
• E. Titan propulsion system family
  The Titan propulsion system family is a series of liquid-fueled rocket engines and stages developed for the U.S. Titan launch vehicles, used extensively for military missiles and space launch missions during the Cold War and beyond.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
