At 1:30 on December 2, 2013, the “Chang’e III” lunar probe was launched at the Xichang Satellite Launch Center and successfully landed on the lunar surface on December 14, after which the lunar surface Patrol and investigation of the task. “Chang’e III ” from launching, landing the moon to normal activities, which are rich in what are rich in geographical elements? First, from the “Chang’e III” launch time analysis of the launch window of its influencing factors “Chang’e Why did the launch date of the No. 3 ”detector be chosen at 1:30 on December 2?
