Shenzhou 8 () was an unmanned flight of China's Shenzhou program,〔 〕 launched on October 31, 2011 UTC, or November 1 in China, by a modified Long March 2F (CZ-2F) rocket which lifted off from the Jiuquan Satellite Launch Center.〔 The Shenzhou 8 spacecraft was automatically docked with the Tiangong 1 space module (launched on 29 September 2011) on November 3 and again on November 14, 2011.〔http://www.msnbc.msn.com/id/45136872/ns/technology_and_science-space/#.TrGspPRKOuc〕 This unmanned docking—China's first—was followed in 2012 with the manned Shenzhou 9 mission, which performed a manned docking (also China's first) with the Tiangong 1 module.〔 Only the Soviet Union (Russia), Japan〔ETS-VII〕 and the European Space Agency had achieved automatic rendezvous and docking prior to China's accomplishment. ==History== On September 29, 2008, Zhang Jianqi (), Vice Director of China manned space engineering, announced in an interview of China Central Television 〔(【引用サイトリンク】title=China will launch small space station in 2010–2011 (in Chinese) )〕 that Tiangong 1, an 8-ton "target vehicle", would be launched in 2010 (now 2011), and that Shenzhou 8, Shenzhou 9 and Shenzhou 10 were all intended to dock with it. On October 1, 2008, Shanghai Space Administration, which participated in the development of Shenzhou 8, stated that they have succeeded in the simulated experiments for the docking of Tiangong 1 and Shenzhou 8.〔(【引用サイトリンク】title=Simulated docking of Shenzhou 8 has succeeded (in Chinese) )〕 , the launch of Shenzhou 8 was planned for early 2011.〔 〕 By March 2011, the launch had been postponed until October 2011.〔 Shenzhou 8 was launched at 21:58 UTC on October 31, 2011 (November 1 in China) by a modified Long March 2F (CZ-2F) rocket. The launch lifted off from 921/SLS-1 Launch Pad at the Southern Launch Site of the Jiuquan Satellite Launch Center.〔 The unmanned Shenzhou 8 mission successfully docked with Tiangong-1 on 2 November 2011 GMT, marking China's first orbital docking.〔("Chinese spacecraft dock in orbit". ) BBC News, 2011-11-02.〕 Shenzhou 8 undocked from Tiangong-1 on 14 November, before successfully completing a second rendezvous and docking, so as to test the reusability of the docking system.〔("2nd docking of Tiangong-1 & Shenzhou-8 on schedule". ) Xinhua, 7 November 2011.〕〔("Chinese spacecraft Shenzhou-8 disengages from space lab module Tiangong-1". ) Xinhua, 14 November 2011.〕〔("China completes second space docking" ).
