JIUQUAN, Oct. 17 (Chinadaily) -- China launched the Shenzhou XI manned spacecraft on Monday morning to transport two astronauts to the Tiangong II space laboratory.

The spacecraft was sent skyward at 7:30 am atop a Long March 2F rocket from the Jiuquan Satellite Launch Center in Northwest China. It is carrying two male astronauts – 49-year-old Jing Haipeng and 37-year-old Chen Dong.

After the launch, the spacecraft will travel two days before docking with the Tiangong II, which was lifted from the Jiuquan center in mid-September. Then the astronauts will enter the space lab and stay there for 30 days, which will be the longest space stay by Chinese astronauts.

The core tasks of the Shenzhou XI mission are to test rendezvous and docking technologies for the country's planned space station, to verify the life-support capability of the spacecraft-space lab combination as well as conduct scientific research and test engineering experiments, according to Wu Ping, deputy director of the China Manned Space Agency.

Prior to the Shenzhou XI, China had sent five spacecraft and 10 astronauts to space since 2003, when it lifted the Shenzhou V to carry the nation's first astronaut Yang Liwei, who is now a senior space official, into space.

China is the third country in the world that has independently fulfilled manned spaceflight following the former Soviet Union and the United States.

China's manned space program, a source of national pride, aims to place a permanent manned space station, which will consist of three parts — a core module attached to two labs, each weighing about 20 metric tons —into service around 2022, according to the manned space agency.
