The launch of Tiangong-1 can be said to be a major development of China's space flight and a reflection of its comprehensive national strength. China's position in the world has improved. This is the first and most important step for China to build a space station, and China is moving towards a space power.

The successful launch of Tiangong-1 is impressive. It marks that China has its first space laboratory in space. The successful launch not only increased the pride of China people, but also showed the face of China as a space power, which is a huge step towards the maturity of China's space program and has a milestone significance.

Second, the introduction of Tiangong No.1:

Tiangong-1 (Tiangong-1 or Tiangong 1) is China's first target aircraft and space laboratory, belonging to manned spacecraft, which was developed by China Academy of Space Technology and Shanghai Institute of Space Technology under China Aerospace Science and Technology Corporation. The altitude is10.4m, and the weight is 8.5t. It was launched at Jiuquan Satellite Launch Center at 2 1 1 on September 29th, 20 1, and was carried by the Long March II FT 1 rocket, with a total length of 52m and a carrying capacity of 8.6t.. Tiangong-1 was designed to run in orbit for two years.

The main tasks of Tiangong-1 are as follows: Tiangong-1 target aircraft is the rendezvous and docking target, and it cooperates with Shenzhou-8 to complete the space rendezvous and docking flight test; Ensure the life and work of astronauts during their short stay in orbit and ensure the safety of astronauts; Carry out space applications (including space environment and space physical exploration, etc.). ), space science experiments, space medical experiments and space station technology experiments; Initially establish a space experimental platform with short-term manned and long-term unmanned independent and reliable operation, and accumulate experience for building a space station.

The launch of Tiangong-1 marks the second step of China's space "three-step" strategy (that is, mastering the space rendezvous and docking technology and establishing a space laboratory); At the same time, it is also the starting point of China Space Station, which indicates that China has the ability to build a preliminary space station, that is, a short-term unattended space station.

In 201110, Tiangong-1 successfully docked with Shenzhou-8 spacecraft, making China the third country in the world to independently master the space rendezvous and docking technology. On June 2012 18, the Shenzhou-9 spacecraft successfully rendezvous and docked with the Tiangong-1 target aircraft, and three Chinese astronauts entered the on-orbit aircraft for the first time. On June 20 1313, Shenzhou-10 successfully completed the automatic rendezvous and docking with Tiangong-1. After the return of Shenzhou-10 spacecraft, Tiangong-1 completed its main task.

2065438+321March 2006, I learned from the China Manned Space Engineering Office that the Tiangong-1 target aircraft, which had been in orbit for 1630 days, officially terminated its data service after completing the rendezvous and docking with three shenzhou spaceship ships and various test tasks, because it had been in service for two and a half years. Ground tracking observation shows that Tiangong-1 is still flying in the designed orbit. According to the China Manned Space Engineering Office, the flight trajectory of Tiangong-1 is still under continuous and close monitoring. According to the forecast, the flight orbit of Tiangong-1 will gradually decrease in the next few months, and Tiangong-1 will actively derail and fall into the South Pacific at the end of its life.
