1. Space Transportation System
China will build a stronger space transportation system, keep improving its launch vehicle series, and enhance their capabilities of entering space.
It will enhance the reliability and adaptability of launch vehicles in service, and develop new-generation launch vehicles and their upper stages, implement the first flight of the Long March-5, Long March-6 and Long March-7 launch vehicles. The Long March-5 will use non-toxic and pollution-free propellant, and will be capable of placing 25 tons of payload into the near-Earth orbit, or placing 14 tons of payload into the GEO orbit. The Long March-6 will be a new type of high-speed response launch vehicle, which will be capable of placing not less than 1 ton of payload into a sun-synchronous orbit at a height of 700 km. The Long March-7 will be capable of placing 5.5 tons of payload into a sun-synchronous orbit at a height of 700 km.
It will conduct special demonstrations and pre-research on key technologies for heavy-lift launch vehicles.
2. Man-made Earth Satellites
China will build a space infrastructure frame composed of Earth observation satellites, communications and broadcasting satellites, plus navigation and positioning satellites, and will develop a preliminary long-term, sustained and stable service capability. China will develop new types of scientific satellites and technological test satellites.
1) Earth observation satellites
China will improve its present meteorological, oceanic, and resource satellite series and its small satellites constellation for environmental and disaster monitoring and forecasting. It aims at developing and launching new-generation GEO meteorological satellites, stereo mapping satellites, radar satellites for environment and disaster monitoring, electromagnetic monitoring test satellites, and other new-type Earth observation satellites. It will work to make breakthroughs in key technologies for interferometric synthetic-aperture radar and gravitational field measurement satellites. It will initiate a high-resolution Earth observation system as an important scientific and technological project and establish on the whole a stable all-weather, 24-hour, multi-spectral, various-resolution Earth observation system.
2) Communications and broadcasting satellites
China will improve satellites for fixed communications services, television and radio service satellites and data relay satellites; develop satellites for mobile communication service; and develop a platform of higher capacity and higher power for new-generation GEO communications and broadcasting satellites.
3) Navigation and positioning satellites
Based on "three-step" development plan - from experimental system to regional system and then to global system, China will continue building its Beidou satellite navigation system, implementing a regional Beidou satellite navigation system before 2012, whose navigation and positioning, timing and short-message services will cover the Asia-Pacific region. China aims at completing the global Beidou satellite navigation system by 2020, comprising five GEO satellites and 30 non-GEO satellites.
4) Scientific satellites and technological test satellites
China will develop and launch a Hard X-ray Modulation Telescope satellite, Shijian-9 new technology test satellite, and returnable satellites. It will begin to implement projects of quantum science test satellite and dark matter probing satellite.
3. Human Spaceflight
China will push forward human spaceflight projects and make new technological breakthroughs, creating a foundation for future human spaceflight.
It will launch the Shenzhou-9 and Shenzhou-10 spaceships and achieve unmanned or manned rendezvous and docking with the in-orbit Tiangong-1 vehicle.
China will launch space laboratories, manned spaceship and space freighters; make breakthroughs in and master space station key technologies, including astronauts' medium-term stay, regenerative life support and propellant refueling; conduct space applications to a certain extent and make technological preparations for the construction of space stations.
China will conduct studies on the preliminary plan for a human lunar landing.
