Target entity: Hall-effect thrusters Context triple: [Psyche spacecraft, propulsion, Hall-effect thrusters]
-
A.
Hall-effect thrusters
chosen
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.
NEXT-C ion thruster
The NEXT-C ion thruster is a high-efficiency NASA-developed electric propulsion system designed for deep-space missions, providing continuous low-thrust acceleration using ionized xenon.
-
C.
Draco thrusters
Draco thrusters are small hypergolic rocket engines developed by SpaceX to provide attitude control and orbital maneuvering for its spacecraft.
-
D.
Space Shuttle electrical power system
The Space Shuttle electrical power system was the orbiter’s integrated network of fuel cells, distribution buses, and control equipment that generated and supplied electricity to all onboard systems and payloads.
-
E.
The Exploration of Cosmic Space by Means of Reaction Devices
The Exploration of Cosmic Space by Means of Reaction Devices is a pioneering 1903 scientific paper that laid the theoretical foundations of modern astronautics and rocket science.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
