BEIJING, June 14 (Xinhuanet) -- The three Shenzhou X astronauts moved into the Tiangong-1 space module on Thursday following a successful automatic docking.

The spacecraft completed the docking procedure at 1:18 pm, according to the Beijing Aerospace Control Center.

It is the fifth docking between a Shenzhou spacecraft and the unmanned space module conducted by China.

The control center said Shenzhou X, launched on Tuesday from the Jiuquan Satellite Launch Center in Gansu province, began to approach the Tiangong-1 automatically at 10:48 am, making contact with it at 1:11 pm.

The astronauts, sitting in the spacecraft's re-entry capsule, monitored and reported the docking operation to the control center.

After the two spacecraft were locked together and the space module was checked, astronaut Nie Haisheng opened the doors leading to Tiangong-1 with help from fellow astronaut Zhang Xiaoguang.

The three astronauts, clad in blue spacesuits, then floated into the module one by one. They later waved to a camera in the module.

In coming days they will live in the space module, carrying out scientific and technical experiments and giving a lecture to students on Earth, Wu Ping, spokeswoman for the program, said.

There will also be a manual docking between Shenzhou X and the module, although Wu did not give a date for this.

The mission is expected to help scientists verify and improve space rendezvous and docking technology, crucial for assembling an orbiting space station.
