Shenzhou-8 spacecraft is the eighth spacecraft in China Shenzhou series. It has a three-cabin structure and consists of an orbital module, a return module and a propulsion module. Shenzhou VIII is an improved spaceship with a total length of 9 meters, a maximum diameter of 2.8 meters and a take-off mass of 8,082 kilograms. Shenzhou-8 spacecraft has greatly improved its technology. After its launch, it docked with Tiangong-1 and became a small space station.

Shenzhou-8 spacecraft is a three-compartment structure, which consists of an orbital module, a return module and a propulsion module. The automatic docking mechanism is installed at the front end of the spacecraft orbital module and has the functions of automatic and manual rendezvous, docking and separation. Shenzhou VIII will basically become a standard space ferry in China, and mass production will be realized in the future.

Technical characteristics of Shenzhou VIII

On the basis of the previous spacecraft, the Shenzhou-8 spacecraft has made great technical improvements. There are more than 600 sets of equipment in the whole ship, and more than half of the equipment has changed its technical status. Among them, newly developed equipment and new equipment account for 65,438+05%, and the main changes are in two aspects:

It has automatic and manual rendezvous and docking functions, so some new equipment has been added and improved. For example, we have newly developed a heterogeneous and isomorphic peripheral configuration and a variety of rendezvous and docking measurement equipment, which are used for flight software and control software for autonomous control of rendezvous and docking.

It is also newly designed and developed. In order to meet the rendezvous and docking mission, the spacecraft is equipped with translation and thrust engines. At the same time, the astronauts' manual control equipment has also been improved.

Based on the previous 57 days of autonomous flight capability, the spacecraft has the docking capability of 180 days. Due to the adoption of new solar cells, the power generation capacity of Shenzhou-8 spacecraft has increased by 50%. The parachute system and landing buffer system of the spacecraft have also been technically improved to improve the reliability of use.
