The 15-day Shenzhou-10 mission that concluded Wednesday was perfect with smooth implementation and fruitful achievement, an aerospace official said Wednesday at a press conference.

The Shenzhou-10 mission has made China's manned spacecraft flights successful in a consecutive way, and put a satisfactory end to the first phase of the second step of China's manned space program, Wang Zhaoyao, director of China's manned space program office, told the press conference held shortly after the reentry capsule of Shenzhou-10 spacecraft landed with three astronauts aboard safe and sound.

Wang said the success of Shenzhou-10 mission also laid a solid foundation for construction of China's manned space station in the future.

He said the three astronauts, Nie Haisheng, Zhang Xiaoguang and Wang Yaping performed excellently and the whole process from spacecraft launch to docking with Tiangong-1 target orbiter and its returning and recovery was very smooth, or could even be called "perfect".

Wang said experience has been accumulated through a series of space experiments and activities such as on-orbit repair operation, space lecture and fly-around and rendezvous test with the target module Tiangong-1.

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.
