China will vigorously develop space science and conduct deep-space explorations, said Yuan Jiajun, chief commander of China's space program and president of the China Academy of Space Technology, at the 5th Young Scientist Forum of China Association for Science and Technology opened Tuesday in Shanghai.

The goals China set for its space science development are: build satellite-to-earth observation system of long-term stable operation; construct an independently running satellite broadcast and communication system; construct an independent satellite navigation and positioning system; realize manned spacecraft flight and set up initially coordinated manned spacecraft flight experiment system.

China will launch space science experiment satellites to form a solar observation system of long-term stable operation; satellites will be launched to test new technologies in the fields of payload of various kinds of satellites as well as satellite platforms; lunar probe satellite, soft landing device and lunar probe capable of sample collection and automatic return will also be launched to comprehensive explore into the distribution of lunar resources.

A satellite-to-earth observation system over land, ocean, meteorology and environment will be set up to realize precise, real-time, continuous and all-weather observation through means of visible light, infrared ray and macro wave.

Efforts will also be made to construct a satellite broadcast and communication system covering fixed-line communication, mobile communication, live TV broadcast, live video broadcast, broadband multi-media communication, regional mobile communication and data relay. The goal is to realize over 100,000 network supported users and 100 percent of coverage by satellite TV and broadcast.

The country's second-generation regional navigation positioning system will be extended into a global positioning system to realize platformless, three-dimensional and high-precision navigation, positioning and time service.

On the base of manned space flight, breakthroughs will be made in rendezvous and space walking technologies. A "space laboratory program" is planned to achieve a space system capable of long-term independent flight and short-term human cares, so as to lay a technological foundation for developing space station.
