Tiangong-2 (Chinese: ; pinyin: Tiāngōng èrhào; literally: "Heavenly Palace 2") is a planned Chinese space laboratory and part of the Project 921-2 space station program. Tiangong-2 was originally expected to be launched by the China National Space Agency by 2015[1] to replace the prototype module Tiangong-1, which was launched in September 2011.[3] In September 2014, its launch was delayed to 2016.[4]

History[edit]

In 2008, the China Manned Space Engineering Office published a brief description of Tiangong-2 and its successor Tiangong-3, indicating that several manned spaceships would be launched to dock with Tiangong-2.

In March 2011, Chinese officials stated that Tiangong-2 was scheduled to be launched by 2015,[5][1] following the deorbit of Tiangong-1. Unmanned cargo spacecraft will dock with the station,[1] allowing for resupply.[6][dated info]

In September 2014, its launch was pushed to 2016.[4] Once in orbit, it is planned to be visited by manned mission Shenzhou 11 and unmanned resupply mission Tianzhou 1. That resupply mission will use the unmanned resupply craft Tianzhou.[7]

Development specifications[edit]

The expected specifications of Tiangong-2 will be as follows:

  • Crew size: 3, with 20 days of life support resources.[5]
  • Length: 14.4 metres (47 ft).[2]
  • Maximum diameter: 4.2 metres (14 ft).[2]
  • Mass: 20,000 kilograms (44,000 lb).[2]
