NASASpaceflight.com. 28 September 2011. Retrieved 22 October 2011.〕 serving as both a manned laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities.〔 Launched unmanned aboard a Long March 2F/G rocket〔 on 29 September 2011,〔 it is the first operational component of the Tiangong program, which aims to place a larger, modular station into orbit by 2023.〔 , Tiangong-1 was projected to be deorbited in 2013,〔("China to launch module for future space station" (PDF) ). PhysOrg.com. 28 September 2011. Retrieved 10 March 2013.〕 and replaced over the following decade by the larger Tiangong-2 and Tiangong-3 modules. However, Tiangong-1 remains in orbit as of 2015. Tiangong-1 was 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,〔〔 while the manned Shenzhou 9 mission docked in June 2012.〔 A third and final mission to Tiangong-1, the manned Shenzhou 10, docked in June 2013.〔〔 The manned missions to Tiangong-1 were notable for including China's first female astronauts, Liu Yang and Wang Yaping.〔〔 ==Design and development== The China National Space Administration (CNSA) designed Tiangong-1 as an "space-laboratory module", capable of supporting the docking of manned and autonomous spacecraft. In 2008, the China Manned Space Engineering Office (CMSEO) released 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.〔 On 29 September 2008, Zhang Jianqi (), vice-director of the CMSEO, declared in an interview with China Central Television (CCTV)〔 that Tiangong-1 would be launched in 2010 or 2011. Xinhua later stated that Tiangong-1 would be launched in late 2010, and declared that the renovation of ground equipment was in progress.〔 However, the launch did not ultimately take place until 2011. By mid-2011, the construction of Tiangong-1 was complete, and its systems and thermal properties were undergoing testing. Testing was also conducted on the Long March 2F carrier rocket on which Tiangong-1 would be launched; technicians undertook particularly extensive safety tests on the rocket in August and September 2011,〔 following the launch failure of a Long March 2C rocket on 18 August. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tiangong-1」の詳細全文を読む スポンサード リンク
