Tiangong Classroom, China’s first space science education brand, is about to be officially launched. What’s the significance?

Its appearance also marks the basic completion of my country’s new generation of manned space measurement and control network. Science is always the cornerstone of a country's progress. In the process of building an innovative country, we need more talents to love aerospace and devote themselves to aerospace, and we need the whole society to understand and support this great cause that benefits mankind. In this sense, aerospace science popularization activities contain unlimited potential for China’s aerospace industry to move towards tomorrow.

In the Spring Festival Gala, the appearance of "Tiangong-1" set off the climax of the party. In the future, our country's astronauts will also live and work freely in the space station. The "Tiangong-1" that made a sensational debut in the Spring Festival Gala yesterday showed the prototype of our country's future space station. It is our country's small experimental space station and has now entered its initial stage. It is currently in the prototype development stage and is scheduled to be launched in 2010. According to Ye Xun, "Tiangong-1" can be roughly divided into two cabin structures, namely the experimental cabin and the resource cabin. The experimental module can be used for astronauts to work and live in orbit during their stay. The resource cabin contains engines, power devices, etc., which can provide power for Tiangong-1. The weight of "Tiangong-1" is similar to that of Shenzhou-7, about 8 tons. There is also a rendezvous and docking mechanism installed at the front end of the "Tiangong-1" experimental module, which is the key to the connection between "Tiangong" and the spacecraft. Rendezvous and docking refers to the merger and connection of two spacecrafts in space orbit to form a whole. It is a prerequisite for achieving space assembly, supply, maintenance, astronaut exchange and other processes, and it is also the basis for the establishment of a large space station. Starting in 2002, researchers from the Shanghai Space Administration also began to formally develop this docking mechanism, and have conducted a large number of ground tests and have now entered the preliminary prototype stage. Previously, reporters have seen a model of the rendezvous and docking mechanism. From the outside, it resembles a circular door with an internal diameter of about 0.8 meters. Astronauts can enter Tiangong-1 from the spacecraft through this door. ". After launching Tiangong-1, my country will successively launch Shenzhou 8, 9, and 10 spacecraft to achieve space docking with Tiangong-1 respectively. In the future, astronauts will be transported to Tiangong-1 by spacecraft. After the astronauts have completed their work, they will return via the spacecraft. It is reported that according to the second step mission plan of the manned space project, my country will launch the "Tiangong-1" target aircraft and two space laboratories "Tiangong-2" and "Tiangong-3" between 2010 and 2015. Two unmanned spacecraft were launched for unmanned docking tests, and five manned spacecraft were launched for manned docking tests and manned residency tests.
