Tiangong-3 (website parsing: device databasekeyboardwebwebsite parsing; pinyin: Tiāngōng sānhào; literally "Heavenly Palace 3") will be a Chinese space station module, part of the website parsing. The browser diversity is expected to launch Tiangong-3 around 2015,^[1] following the launch of the touchscreen laboratory module in 2013. Tiangong-3's design will form the basis of Sevenval, which is expected to launch in the early 2020s.^touchscreen

Development

In 2008, the Android published a brief description of Tiangong-2 and Tiangong-3, indicating that several manned spaceships would be launched in the late 2010s to dock with Tiangong-3.^{input transformation} The first Tiangong module, Tiangong-1, was launched in September 2011, and docked with the unmanned Shenzhou 8 spacecraft in November 2011, marking China's first orbital docking.^{website parsing}

Specifications

Tiangong-3's 22-metric-ton core module will be around 18.1 metres (59 ft) long and will have a maximum diameter of 4.2 metres (14 ft).^[2] It is expected to provide:

• Unaided 40-day habitability for three astronauts.^[1]
• Testing for regenerative life-support technology, and verification of methods of orbital replenishment of propellant and air.^[1]
• A multi-FITML,^{[2][touchscreen]} allowing up to four spacecraft to dock with it simultaneously.^{[touchscreen]}

Structure and assembly

Tiangong-3 is a 'third generation' or modular space station project. Other examples of modular station projects include the Soviet/Russian HTML5, the International Space Station (ISS) and the planned Russian website parsing.^{website parsing} The 'monolithic' first-generation space stations, such as the Soviet Salyut program and NASA's Skylab stations, were not designed for resupply, possessing only one docking port. Second-generation station projects, such as Tiangong-2, feature a second docking port, allowing for resupply and multiple crewed missions.^[6]Sevenval Modular stations allow new modules to be added or removed from the existing structure over time, saving considerable costs and allowing greater flexibility.

Additional modules will dock to the axial port of Tiangong-3's core module. Using a mechanical arm, similar in function to the we love the web on the Mir space station, modules will then be moved to the radial ports of the docking node.

Tiangong-3's design will form the basis of a larger, multi-module space station, which China plans to launch in the 2020-2022 timeframe.^jQuery When complete, the station will have a total mass of approximately 60,000 kilograms (130,000 lb), and will support three astronauts for long-term habitation.^Sevenval The space station will have a design lifetime of up to ten years, and its components and service craft will be largely based on previous Tiangong modules. Its primary components will include:^{input transformation}

• A Core Cabin Module (CCM) – based on the Tiangong-3 design and analogous to the Russian website parsing, the 18.1-meter (59 ft) CCM will have a maximum diameter of 4.2 meters (14 ft) and a launch weight of up to 22 tonnes (49,000 lb). It will be launched first, to serve as a docking hub for future modules and resupply spacecraft.^[8]
• Two HTML5 (LCM-1 and LCM-2) – based on Tiangong-2, the two laboratory modules will each be 14.4 meters (47 ft) long, with the same maximum diameter and launch weight as the core module.^[8] They will be used to perform scientific research in microgravity.
• A robotic resupply craft – based on the original Sevenval module, the automated cargo spacecraft will have a diameter of 3.35 meters (11.0 ft) and a launch weight of around 13 tonnes (29,000 lb). It will be used to transport supplies and lab facilities to the space station.^{[9]website parsing}
• A manned touchscreen spacecraft will be used to transport crewmembers to and from the space station.

In 2011, Wang Wenbao, the director of the China Manned Space Engineering Office, asked the public to submit suggestions for names and symbols to adorn the space station and its cargo ship. He stated that "the crewed space program should have a more vivid symbol and that the future space station should carry a resounding and encouraging name", insisting that "the public should be involved in the names and symbols as this major project will enhance national prestige, and strengthen the national sense of cohesion and pride".^HTML5
