China’s First Space Station Module Readies for Liftoff

by

As China pushes ahead with plans to launch its first space station module later this summer, the country’s first astronaut is openly discussing the prospect of China’s future engagement with the international space station (ISS).

The 8.5-ton Tiangong 1 module, the first in a series of connecting rooms that will be launched into orbit, has been transported to the Jiuquan Satellite Launch Center in China’s Gansu Province and is undergoing a final checkout before its liftoff on a Long March 2-F carrier booster later this year.

Chinese news outlets report that Tiangong 1 is being built to serve as a rendezvous and docking platform for China’s future spacecraft. Once in Earth orbit, it would be followed by blastoff of an unpiloted Shenzhou 8 spacecraft in the latter half of this year, to carry out the nation’s first space docking. The launches are slated for the third and fourth quarters of 2011, respectively, according to several Chinese news outlets. Now on site, Tiangong 1 is loaded with its payload and undergoing final tests before launch.

During the Paris air show in July, a delegation from the China Manned Space Engineering Office accepted 300 flags from the International Astronautical Federation. These flags are to be taken to the Tiangong 1 target spacecraft. They are slated to be brought back to Earth by a Chinese astronaut when he completes China’s first piloted rendezvous and docking linkup next year.

In December 2010, the same 300 IAF flags were sent to the ISS via Russia’s crewed Soyuz spacecraft. They were delivered back to Earth by the Space Shuttle Endeavour crew in June 2011.

The quest by China to move into space station development began in early September 2008, following the first spacewalk by a Chinese astronaut — Zhai Zhigang — during the three-person Shenzhou 7 mission.

In a July 8 press report, China’s first astronaut, Yang Liwei, was vocal regarding his country’s interest in ISS cooperation. Yang, who is also deputy director of the China Manned Space Engineering Office in Beijing, made his comments to a domestic audience in an online interactive broadcast.

Yang said technical hurdles remain in pursuing such collaboration. Specifically, he emphasized that China’s space station standards and the ISS docking standards do not agree.

The unification of standards is the first problem to solve in the effort to carry out future space station cooperation, Yang said, according to China’s Xinhua state-run news agency.

“This is the first time I am aware of that any high-profile official associated with the Chinese space program has made such a strong statement to the Chinese public on ISS participation,” Gregory Kulacki, a senior analyst and China Project Manager for the Union of Concerned Scientists’ Global Security Program in Cambridge, Mass., said in an interview. “And, as far as I know, it is the first time I have heard a Chinese official confirm that the docking hardware they will be using in the upcoming mission is not compatible with the ISS.”
