BEIJING - China's lunar probe Chang'e-3 landed on the moon on Saturday night, according to sources in charge of the mission. The entire process of soft-landing lasted 12 minutes and was performed by the probe itself, said the sources on Saturday, adding that the Chang'e-3 mission has so far proceeded as planned.+ [. w) z; B- F: J7 m# d/ x, r( _

The probe started decelerating from 15 km above the lunar surface and its relative speed was reduced from 1.7 km/s to nil. It stayed suspended at 100 meters above the moon to assess the landing area to avoid obstacles and locate the final landing spot.! K( v9 Z9 r# L
