BEIJING - China will launch the Shenzhou IX and Shenzhou X spacecraft and achieve space rendezvous and docking missions with the orbiting Tiangong-1 vehicle in 2012, a spokesman for the China National Space Administration said Thursday.

Spokesman Zhang Wei made the announcement at a press conference held in Beijing for the release of a white paper titled "China's Space Activities in 2011."

However, the spokesman did not unveil a detailed timetable for the launches.

China on Thursday issued the white paper on the development of the space industry since 2006 and the major tasks for the next five years.

The white paper was the third white paper on the country's space activities issued by the State Council Information Office, following one in 2000 and another in 2006.

The Chinese government has made the space industry an important part of the nation's overall development strategy and adhered to the exploration and utilization of outer space for peaceful purposes, the white paper said.

Over the past few years, China has ranked among the world's leading countries in certain major areas of space technology, it said, adding that in the next five years, there will be new opportunities for the country's space industry.

At the same time, China will work together with the international community to maintain a peaceful and clean outer space environment and endeavor to promote world peace and development, the document said.

Future missions

Major tasks listed in the white paper for the next five years include a space transportation system, Earth satellites, human spaceflights and deep-space exploration.

The country will launch Shenzhou IX?and Shenzhou X?and achieve unmanned or manned rendezvous and docking with the currently orbiting Tiangong-1 vehicle, the paper said.

China also plans to launch space laboratories, a manned spaceship and space freighters, and will start research on the preliminary plan for a human landing on the moon, the document said.

As an important part of deep-space exploration, the country's lunar probe projects follow the idea of "three steps" -- orbiting, landing and returning.

In next five years, the country plans to launch orbiters for lunar soft landing, roving and surveying to implement the second stage of lunar exploration, then it will start the third-stage project of gathering samples of the moon's surface matter and getting those samples back to Earth, the white paper said.

China will also build a space infrastructure frame composed of Earth observation satellites, communications and broadcasting satellites, as well as navigation and positioning satellites.

According to Spokesman Zhang Wei, China will also conduct special project demonstrations in other deep-space projects, including an exploration of Mars.

International cooperation

China has signed 66 international space cooperation agreements with 22 states and regions, and 44 of them currently remain in effect, Zhang said at the press conference.

Openness has always been a key principle of China's space program, he said.

The country has engaged in 12 bilateral cooperation mechanisms within intergovernmental frameworks, Zhang said, adding that China has exported communications satellites to Nigeria, Venezuela and Pakistan, and has also contracted with countries, including Bolivia, Belarus, Indonesia and Laos, to export satellites.

China is willing to provide space products and services to more countries and regions, especially developing countries, on the basis of equality, mutual benefit, and peaceful utilization.

Moreover, Zhang stressed that China adheres to a principle of peaceful development in its space missions and the use of outer space for peaceful purposes.

By clearly listing "peaceful development" as a key principle that governs China's space missions, Thursday's white paper demonstrates the nation's resolve in carrying out space activities in a peaceful way, Zhang said.

"It has been a common aspiration for the whole of mankind to explore, develop and utilize space for peaceful purposes," he noted.

The white paper says that China always adheres to the use of outer space for peaceful purposes, and opposes the weaponization of, or an arms race in, outer space.

"China develops and utilizes space resources in a prudent manner and takes effective measures to protect the space environment, ensuring that its space activities benefit the whole of mankind," the paper reads.

Moreover, Zhang said that Chinese scientists are keeping in close contact with their Russian peers on the situation of the Yinghuo-1 Mars orbiter.

The orbiter was launched along with Russia's Phobos-Grunt (Phobos-Soil) spacecraft last month, but the spacecraft failed to complete the orbital transfer scheduled to take it on the path to Mars.

Russian scientists have been making unremitting efforts to try to save the Chinese orbiter, Zhang said.

Major progress

According to the white paper, breakthroughs have been made in major space projects, including human spaceflight and lunar exploration, since 2006.

From September 25 to 28, 2008, China successfully launched the Shenzhou VII?manned spacecraft and became the third country in the world to master the key technology of astronaut space extravehicular activity.

In November 2011, China accomplished the first unmanned space rendezvous and docking test between the Tiangong-1 space lab module and Shenzhou VIII?spaceship.

Moreover, the country's lunar probe projects have achieved milestone breakthroughs over the past five years. China successfully launched two lunar probes, the Chang'e-1 on October 24, 2007, and Chang'e-2 on October 1, 2010.

The first probe retrieved a great deal of scientific data and a complete map of the moon while the second created a full higher-resolution map of the moon and a high-definition image of Sinus Iridium.
