On 29 December, China successfully sent the Tianhui 4 satellite into space from the Jiuquan Satellite Launch Centre. The satellite was launched by a CZ-2D and lifted off at 19:13 BJT.
Tianhui 4, built by China Academy of Space Technology in Beijing, will be used to conduct scientific experiments, land resource surveys and geologic information collection, the company said. Tianhui means "sky mapping" in English. With that launch, the Long March fleet has carried out 47 successful launches in 2021. In total, China accounts for 54 orbital launches so far.
