Two to three space laboratories may be launched by China between 2010 and 2015, roughly less than a decade before the nation embarks upon a space station in 2020, a top scientist said.
Gu Yidong, former chief commander and a designer for China's manned space program, said that space laboratories will be docked on a number of spaceships to test for accurate docking technology. He made the remarks at an annual academic meeting of the Chinese Society of Space Research in Dalian over the weekend.
The docking technology is an important feature that China must master before moving forward with the construction of a space station.
Any miscalculations during a docking could lead to the collision of spacecraft, according to the official website of China's manned space program, cmse.gov.cn.
In addition to the docking technology, China also needs to achieve technological breakthroughs in the length of stay in space for astronauts, the long-term unattended operation of a spacecraft and transferring supplies by cargo spacecraft, according to the website.
China is now in the second phase of a three-step plan that the nation drafted to carry out its manned space program.
According to the official website, the second phase includes the launch of the target spacecraft Tiangong I, and two space laboratories, Tiangong II and Tiangong III.
Two unmanned spaceships and five manned spaceships will also be launched during the phase to dock on the Tiangong crafts to test the docking technology.
