China's Shenzhou-10 spacecraft mission 'perfect'(2)

Wang said China had successfully launched Tiangong-1 orbiter, Shenzhou-8, -9 and -10 spacecraft since September 2011, and completed four automatic and two manual docking maneuvers, fulfilling the tasks set for the first phase of the second step of the country's manned space program.

He said the main tasks in this phase, approved by the Chinese government in February 2005, include the mastering of extravehicular activities by astronauts and rendezvous and docking technologies.

Wang said China had made breakthroughs in these two tasks. Moreover, it had mastered the technologies of controlling and operating the conjoint spacecraft and target orbiter, and initially establishing and improving the guarantee system for the astronauts to stay on the orbit.

Furthermore, China has also benefited in the following three aspects from a series of spacecraft missions, Wang said.

Technically, China has accumulated a huge amount of experimental data and flight experience.

China also carried out massive scientific and technical experiments in such fields as space-earth remote sensing, space life science, material science as well as environment survey, Wang said.

The missions have also helped consolidate the basis of China's aerospace technology, elevate the overall capabilities of the nation's space industry, boosted the development of basic science and applied science, and fostered a team of aerospace experts, he added.
