China's first lunar probe, Chang'e-I, completed its 1,580,000-km flying journey to the moon successfully on Wednesday's morning after entering its final working orbit.

The probe, following the instructions of the Beijing Aerospace Control Center (BACC), started its third braking at 8:24 am and entered a 127-minute round polar circular orbit at around 8:35 am after completing the braking.

"The probe will travel along the orbit at a stable altitude of 200 km above the moon's surface. In each circle, it will always pass the two polars," said Wang Yejun, chief engineer of the Beijing Aerospace Control Center (BACC).

The round orbit is also the final destination of the probe, where it is supposed to start carrying out all the planned scientific exploration tasks.

It was originally designed to stay on the orbit for one year, but a researcher estimated that fuel saved by smooth operations and precise maneuvers may prolong its life span.

Chang'e-I, named after a legendary Chinese goddess who flew to the moon, blasted off on a Long March 3A carrier rocket on Oct. 24 from the Xichang Satellite Launch Center in southwestern Sichuan Province.
