Researchers from the China Aerospace Science and Technology Corporation (CASC) have developed the country's first Hall-effect thruster (HET) with an input power of 20 kilowatts that can produce a thrust of one newton, marking a leap for China's HETs from millinewton level to newton level. During a test, the thruster showed stable operation, with a specific impulse of 3068 seconds and working efficiency above 70 percent. HETs could have wide applications in the attitude control of satellites and the use as a main propulsion engine for medium-size robotic space vehicles.
