On September 15, at 22:04, the F T2 launch vehicle equipped with the Long March II space laboratory of the Tiangong II space laboratory was fired at the Jiuquan Satellite Launch Center in China. About 575 seconds later, the Tiangong II successfully separated from the rocket and entered the planned orbit , Launched a successful launch. On September 16, under the precise control of the Beijing Aerospace Control Center, the Temple of Heaven II successfully implemented two orbital controls and successfully entered orbital test orbit. After entering on-orbit test track, ground personnel tested the basic functions and stability of various subsystems on the Tiangong 2 platform and carried out a series of space science experiment activities using the payloads carried.
