Tiangong-1 (Chinese: 天宫一号; pinyin: Tiāngōng yīhào; literally "Heavenly Palace 1") is a Chinese space laboratory module, an experimental testbed to demonstrate the rendezvous and docking capabilities needed to support a space station complex. Launched unmanned aboard a Long March 2F/G rocket on 29 September 2011, it is part of the Tiangong program, which aims to place a larger, modular station into orbit by 2020. Tiangong-1 will be deorbited in 2013, and replaced over the following decade by the larger Tiangong-2 and Tiangong-3 modules.
Tiangong-1 will be visited by a series of Shenzhou spacecraft during its two-year operational lifetime. The first of these, the unmanned Shenzhou 8, successfully docked with the module in November 2011; the manned Shenzhou 9 mission is expected to launch to Tiangong-1 in 2012.
According to the China National Space Administration (CNSA), Tiangong-1 is an 8.5-metric-ton (19,000 lb) "space-laboratory module", capable of supporting the docking of manned and autonomous spacecraft. In 2008, the official website of the CMSEO posted a brief description of Tiangong-1, along with its larger successor modules, Tiangong-2 and Tiangong-3. A model of the space station was revealed in the Chinese Lunar New Year celebration program on CCTV on 25 January 2009.
