China's piecemeal but ambitious space program has made another big take-off on the morning of October 12, 2005, when a couple of new Chinese taikonauts are sent to the orbit by China's state-of the-art Long March rockert.

The Shenzhou VI manned spacecraft blasted off with a loud launch noise for a multi-day orbital stay from its satellite launch center in Qiuquan in northwest China.

Shenzhou VI was lifted into the space by a Long March carrier rocket at 9:00 am Beijing Time.

Fei Junlong, 40, and Nie Haisheng, 41, will make a great deal of experiments during their space journey.

"We have the confidence and ability to fulfil this glorious task. Our only wish is to make the mission a complete success," Fei said before boarding the craft. "Life in space is full of mysteries," Nie added.

China, the third nation to put a man into orbit, insisted ahead of the launch that its aspirations in space were strictly peaceful and that it opposes deploying weapons there. Space officials say they hope to land an unmanned probe on the moon by 2010 and launch a space station.

"We do not wish to see any form of weapons in outer space, so we reaffirm that our space flight program is an important element of mankind's peaceful utilization of outer space," Foreign Ministry spokesman Kong Quan said.

However, Washington sees China's space ambitions as an emerging security concern, with the potential for the Asian giant to boost its military capabilities and eventually challenge US dominance in space.

"US concern about China's space capabilities are first that China might eventually develop the ability to attack US satellites, because the US military is heavily dependent on them," said Phillip Saunders of the Pentagon-linked Institute for National Strategic Studies.

"Second, as China space capabilities improve, it will have the ability also to improve its other military options," Saunders told AFP.
