Tiangong-3 (Template:Zh) was a proposed Chinese space station, part of the Tiangong program. The China National Space Agency (CNSA) was originally expected to launch Tiangong-3 around 2015, following the launch of the Tiangong-2 test laboratory, originally planned for 2013.[1] The goals for the Tiangong-2 and Tiangong-3 laboratories were merged, and the latter was therefore not ordered.[2][3] The first module of the third station of the Tiangong program, Tiangong space station, was eventually launched in 2021.
Development
In 2008, the China Manned Space Engineering Office (CMSEO) published a brief description of Tiangong-2 and Tiangong-3, indicating that several crewed spaceships would be launched in the late 2010s to dock with Tiangong-3.[4] The first Tiangong module, Tiangong-1, was launched in September 2011 and docked with the uncrewed Shenzhou 8 spacecraft in November 2011, marking China's first orbital docking.[5]
Specifications
Tiangong-3 was 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-docking berthing mechanism,[6]Script error: No such module "Unsubst". allowing up to two spacecraft to dock with it simultaneously.Script error: No such module "Unsubst".
