What advanced propulsion system is equipped on the Tianhe module to significantly cut fuel use for station-keeping?
Answer
Hall-effect thrusters
The Tianhe core module is outfitted with Hall-effect thrusters, which represent a highly efficient form of electric propulsion. Utilizing these thrusters allows the station to perform necessary station-keeping maneuvers—adjusting altitude or orientation—while drastically reducing propellant consumption. Estimates suggest that these thrusters can cut fuel use by as much as 90% compared to conventional chemical engines. This high efficiency is crucial for supporting the station's intended multi-year operational lifespan without requiring excessively frequent, costly propellant resupply missions.
