China has successfully tested a new satellite engine with a record-breaking operational duration, marking a significant advancement in aerospace propulsion technology. The engine, developed by the China Academy of Aerospace Propulsion Technology, produced 750 newtons of thrust and operated for over 14 hours during testing, surpassing the typical seven-hour design limit of existing engines like the US-made R-42DM and Europe’s Leros-1B. This achievement allows for more efficient and reliable deployment of large communications, military, and deep-space satellites. The engine was used in a mission to place the Communications Technology Experiment Satellite 26A into orbit approximately 35,800 km above Earth. The extended operation was made possible through a specialized heat- and oxidation-resistant coating, ensuring performance remained unaffected despite the longer runtime.
