The Core Cabin Module (CCM) is the foundation element of the Chinese space station, based on Tiangong-3, as the final stage of Project 921 Tiangong, part of the Chinese space program. The CCM follows the Salyut and Almaz series, Cosmos 557, Skylab, Mir, ISS, Tiangong 1 and Tiangong 2 space stations. It is the first part of a third generation modular space station. Other examples of modular station projects include the Soviet/Russian Mir, Russian OPSEK and International Space Station. Operations will be controlled from the Beijing Aerospace Command and Control Center in the People's Republic of China.

Functions and Systems

The Core Module provides life support and living quarters for three crew members, and provides guidance, navigation, and orientation control for the station. The module also provides the station’s power, propulsion, and life support systems. The module consists of three sections: the habitable living quarter, the nonhabitable service section, and a docking hub.

The living quarters will contain a kitchen and toilet, fire control equipment, atmospheric processing and control equipment, computers, scientific apparatus, communications equipment to see and hear ground control in Beijing, and other equipment.

Electrical power is provided by two steerable solar power arrays, which use photovoltaic cells to convert sunlight into electricity. Energy is stored to power the station when it pass into the Earths shadow. Resupply ships will replenish fuel for the modules propulsion engines for station-keeping, to counter the effects of atmospheric drag.^[1]

Structure

China has established "a good working relationship" with space agencies in Russia, France, Germany and other countries. With a long history of technology transfer with Russia, Chinese Space assets are compatible with Russian orbital hardware. The MARS-500 collaborative study between China, Russia and Europe prepares for a deep space manned mission to Mars.

The docking hub allow the core module to be docked with five other space station modules, including two experimental modules, a cargo ship, and a Shenzhou spacecraft. The axial port of the module will be fitted with rendezvous equipment and a mechanical arm similar to the Russian Lyappa arm used on the Mir space station. The axial port on the docking hub shall be the primary docking port, when new modules arrive, they will first dock here, then the mechanical arm shall attach and move the module to a radial port. Crew and supply ships from the Jiuquan Satellite Launch Center will dock to either of the axial ports of the module.

The first space station, Salyut 1, and other one-piece or 'monolithic' first generation space stations, such as Salyut 2,3,4,5, DOS 2, Kosmos 557, Almaz and NASA's Skylab stations were not designed for re-supply. Generally, each crew had to depart the station to free the only docking port for the next crew to arrive, Skylab had more than one docking port but was not designed for resupply. Salyut 6 and 7 had more than one docking port and were designed to be resupplied routinely during crewed operation. Modular stations can allow the mission to be changed over time and new modules can be added or removed from the existing structure, allowing greater flexibility. The CCM is designed for replenishment of consumables and has a service life of at least 10 years. Length of the module is 18.1m, it is cylindrical with a maximum diameter of 4.2m and an on orbit mass between 20 and 22 thousand kilograms.

Launch

Due for launch around or after 2020, on Long March 5 from Wenchang Satellite Launch Center, into Low Earth Orbit 340 to 450 kilometers above the Earth at an orbital inclination of 42 to 43 degrees, in the center of the Earths Thermosphere.
