The Long March rocket, carrying the Chang'e-2 satellite, blasts off from Xichang, Sichuan province on Friday. The launch started the second phase of China's three-step moon mission, which will culminate in a soft-landing on the moon.

XICHANG, Sichuan — China moved closer to its goal of landing on the moon as its second lunar probe, Chang'e-2, blasted off seconds before 7:00 pm on Friday from the southwestern city of Xichang.

A Long March 3-C launch vehicle, with Chang'e-2 on top, lifted off from the Xichang Satellite Launch Center in Sichuan province at 6:59:57 pm as planned.

The circumlunar satellite separated from the rocket at 7:26 pm to enter the Earth-moon transfer orbit. In less than five days, it will enter a 100-kilometer lunar orbit.

About an hour after the launch, Li Shangfu, director of the Xichang launch center, declared the launch a success to cheers and applause in the command and control hall.

The Chang'e-2 mission is considered "a starting point" of the second stage of China's lunar exploration program that focuses on landing on the moon, a spokesperson for the lunar exploration program, said.

The probe plans to test technology in preparation for an unmanned moon landing in 2013.

Developed with indigenous technology, the 900-million-yuan ($134 million) Chang'e-2 mission will test key components for a soft-landing on the moon.

Friday's mission marked the first time that a Chinese lunar probe directly entered the Earth-moon transfer orbit without orbiting the earth first.

"It is a major breakthrough in rocket design, as it saves energy used by the satellite and speeds up the journey to lunar orbit," Pang Zhihao, a researcher with the China Academy of Space Technology, was quoted by the Xinhua News Agency as saying.

The circumlunar satellite will be sent directly into the Earth-moon transfer orbit and travel some 112 hours before being captured by the moon's gravity and entering the 100-km lunar orbit.
