China's second unmanned lunar probe, Chang'e-2, has successfully completed its third, also the final, braking Saturday, which allowed the satellite to enter a 100 km-high lunar orbit, according to the Beijing Aerospace Control Center (BACC).
Chang'e-2, following instructions from the center, started the third braking at 11:17 a.m. and entered the 118-minute, round working orbit 15 minutes later, changing the satellite's apolune from 1,825 km to about 100 km, the BACC said. The satellite will begin scientific exploration activities soon.
Chang'e-2 lifted off from the Xichang Satellite Launch Center, in southwest China's Sichuan Province, on Oct. 1. The moon probe completed its first braking on Wednesday and the second on Friday.

Chinese Lunar Exploration Program
Chinese Lunar Exploration Program (CLEP) also known as Chang'e program is a program of robotic explorations
·and human missions to the Moon undertaken by China National Space Administration (CNSA). It uses Chang'e lunar orbiters, rovers and soil return spacecraft and adapted Long March 3A, Long March 5/E and Long March 7 launch vehicles. The first spacecraft of the program, Chang'e 1, an un-manned lunar orbiter was successfully launched at Xichang Satellite Launch Center on October 24, 2007. Chang'e 2 is an un-manned lunar probe scheduled for launch in October 2010. It is China's second lunar orbiter, part of the first phase of the Chinese Lunar Exploration Program. The probe will conduct research at a 100-kilometer-high moon orbit. It is similar to Chang'e 1 with some improvements including a better camera with a resolution of 1 meter.
