China Daily Sci-Tech 2011-09-29 21:35(Xinhua) China Daily Sci-Tech 2011-09-29 21:35 China's 1st space lab module Tiangong-1 blasts off China's first space lab module Tiangong-1 blasts off from Jiuquan Satellite Launch Center in Northwest China's Gansu province, Sept 29, 2011. Carried by Long March II-F T1 carrier rocket, the unmanned module will test space docking with a spacecraft later this year. JIUQUAN - China's first space lab module Tiangong-1 blasted off at 9:16 pm Beijing Time (1316 GMT) Thursday from Jiuquan Satellite Launch Center in Northwest China's Gansu province. Commander-in-chief of China's manned space program Chang Wanquan announced Thursday night that the launch of Tiangong-1 space lab module is successful. The unmanned module, carried by Long March II-F T1 rocket, will test space docking with a spacecraft later this year, paving the way for China to become the third country in the world to operate a permanent space station around 2020. Chinese President Hu Jintao and other top leaders watched the launch from the Beijing Aerospace Flight Control Center, witnessing the latest endeavor of China's manned space program since 1992. The Tiangong-1 will orbit the Earth for about one month to await Shenzhou-8 unmanned spacecraft. Once the two vehicles successfully rendezvous, they will conduct the first space docking at a height of 340 kilometers above Earth surface. After two docking tests, Tiangong-1 will await Shenzhou-9 and Shenzhou-10 in the next two years, according to a plan of China's manned space program. The 8.5-tonne Tiangong-1, with a length of 10.4 meters and maximum diameter of 3.35 meters, provides a room of 15 cubic meters for two to three astronauts to live and work. Zhang Shancong, deputy chief designer of the Tiangong-1, told Xinhua that the module carries special cameras which will take hyper spectral images of China's vast farmlands to detect heavy metal pollution and pesticide residue as well as plant disease. Moreover, scientists on the ground will also conduct experiments on photonic crystal, a new material expected to revolutionize information technology, in the low-gravity environment inside the Tiangong-1 as these experiments would be extremely difficult to conduct on Earth's surface.
