China launched the Changโ€™e 2 unmanned lunar probe Oct. 1 on a six-month mission to scout a landing site for the robotic rover it plans to send to the Moon in 2012, according Chinaโ€™s official Xinhua news agency.

The Long March 3C rocket carrying Changโ€™e 2 lifted off from the Xichang Satellite Launch Center in southwest Chinaโ€™s Sichuan Province at 6:59 p.m. local time, placing the spacecraft into an Earth-Moon transit orbit, Xinhua said.

Chinese officials expect Changโ€™e 2 to arrive at the Moon in five days, faster than the 12 days it took Changโ€™e 1 to reach its destination following its October 2007 launch.

Equipped with a 1.5-meter-resolution camera, Changโ€™e 2 is designed to orbit the Moon at an altitude of 15 kilometers.

Wu Weiren, the missionโ€™s chief designer, told Xinhua the probe might be commanded to crash into the Moon, fly farther out into space or return to Earth orbit.

China plans to follow the Changโ€™e 3 lunar lander mission with a rover mission around 2017 to collect rock and soil samples for return to Earth.

Wu told Xinhua China has no timetable for a human lunar mission.
