"The 2.1-meter-long, 0.5-meter-diameter rocket prototype weighed 93 kilograms by launch, and was powered by twin engines, each with a thrust of 550 newtons," Lian Jie, a senior engineer with the institute, told the Global Times. "A turbojet engine was used during the test to simulate a variable thrust liquid rocket engine being used during vertical landing." China's vertical landing rocket prototype in action. CAS CAS rocket prototype soared more than 1,000 meters (3,280 feet), dropped smoothly, slowed down thanks to the engine's reverse thrust, and landed firmly with a precision of less than 10 meters at a speed of less...
