China will soon launch Chang'e 2, the country's second lunar probe satellite. Its main mission is to continue scientific research, and make preparations for the final goal of landing on the moon. 

In a valley some 60 kilometers from downtown is the Xichang Satellite Launch Center.

It's a modern construction providing all the necessary backup for the rocket and the satellite. It includes the launch test, command, track and control, telecommunications, meteorology, and logistics services.

According to Vice Chief Engineer Li Bingli, the center can launch low-temperature propellant rockets, like the Long March 3-C, that can fly deeper into space.

"The Number 3 Launch Tower is responsible mainly for Long March 3-A, like Chang'e 1. The Number 2 Launch Tower is mainly responsible for Long March 3-B and 3-C, which have heavier weight capacities," he said.

The tracking and control station at the center have wireless facilities for record and track the data sent out by the satellite. These signals help locate the satellite's condition, altitude and distance. The signals are then sent to the headquarters in Beijing.

"Chang'e 2's tracking and control is separated into different stages. We are responsible for the first stage, which is from 40 seconds of the launch through 334 seconds, when the rocket goes out of the atmosphere," said Ma Lifu, Tracking & Control Director of Xichang Satellite Lauch Center.

The center has been upgrading its facilities to provide better service.

"The center has established an advanced IP network. It is closely related to the safe launch and control of Chang'e 2," said Gao Jun, Chief Telecom Engineer.

The Long March 3-C rocket is now fixed inside the Number 2 Launch Tower, waiting for the best opportunity for take off.

"A satellite launch during China's National Day holiday could put some pressure on us. We have to pay more attention to ensure its safety," said Li Shangfu, Chief Director of Xichang Satellite Lauch Center.

The Xichang Satellite Launch Center is primarily used to launch powerful rockets and different kinds of satellite. Ever since 1984, it has helped put more than 40 domestic and foreign satellites into space. That's nearly half of the satellites launched in the country. The Chang'e 2 orbiter can once again put Xichang into the global spotlight.
