China has successfully launched the test satellite 21, which will be used to carry out on-orbit verification tests of new space technologies.

CTOnews.com, 16 December, 14:17 today, China successfully launched the test satellite 21 into space by using the long March 11 carrier rocket at the Xichang Satellite launch Center. The satellite entered the scheduled orbit smoothly and the launch mission was a complete success.

CTOnews.com learned that the test 21 satellite, which was developed by the eighth Institute of China Aerospace Science and Technology Corporation, is mainly used to carry out on-orbit verification tests of new space technologies.

This mission is the 456th flight of the long March series of carrier rockets and the 15th launch of the long Eleven rocket. In 2022, the Chang 11 rocket carried out four launch missions, the largest number of launches since the model's first flight.

Dong Xiaobin, the overall designer of the Chang 11 rocket model, said that the Chang 11 rocket carrying out this launch mission was designed by the engine "custom matching" for the first time. Through the joint demonstration of the overall and sub-systems, and according to the characteristics of the mission, the development team selected the solid rocket motor with the best adaptability in performance, which effectively realized the optimization of the launch trajectory and made the Chang 11 rocket fly more stable and accurate. Further improve the ability to perform the contract.
