Tiangong-1 is the first target aircraft in China. It was launched at Jiuquan Satellite Launch Center at 2011+16: 03. The total length of the aircraft is 10.4m, and the maximum diameter is 3.35m It consists of an experimental module and a resource module. Its launch marks the second step of China's space "three-step" strategy.
2011165438+docked with Shenzhou-8 spacecraft in the early morning of1October 3. 20 12,18 (14:14: 04) successfully docked with Shenzhou 9 in the afternoon. Shenzhou-10 spacecraft also completed the automatic rendezvous and docking with Tiangong-1 on June 13 18.
On March 20 16 16, the Tiangong-1 target aircraft officially terminated its data service and fully completed its historical mission. The overall structure of Tiangong-1 is complete, and its running track is still under continuous and close monitoring. The average orbital height is about 370 kilometers, and it decays at the rate of 100 meters per day. It is estimated that it will fall "under control" on 20 18, and the wreckage will fall into the designated sea area.
On April 2, 20 18, around 8: 15, Tiangong-1 target aircraft re-entered the atmosphere, and the re-entry landing zone was located in the middle of the South Pacific. Most devices were ablated and destroyed during re-entry.

The meaning of docking
For China, the successful manned docking mission is an important step to build a space station around 2020, which is not only the latest demonstration of its growing space capability, but also matches its expanding military and diplomatic influence. ?
2065438+On June 20th, 2002, exciting news came from China Astronaut Center. The results of on-orbit body fluid biochemical indexes of Shenzhou-9 astronauts were successfully downloaded, and the results showed that the astronauts were in good health. This is the first time in China to carry out on-orbit monitoring of body fluid stress level, which indicates that the biochemical detection technology of on-orbit medical supervision in China has reached the international advanced level.
