2010年10月1日18时59分57秒,中国西昌卫星发射中心,大地轰鸣,嫦娥二号探月卫星搭乘长征三号丙运载火箭直冲云霄,直接奔向38万公里遥远的月球,这是中国首次运用火箭发射技术成功将卫星直接送入地月转移轨道.“嫦娥二号”卫星在直奔地月转移轨道的中途进行了一次轨道修正,当卫星到达月球附近特定位置时,实施第一次近月制动,进入近月点100公里、周期12小时的月球椭圆轨道.再经过两次近月点制动,进入高度100公里的极月圆工作轨道.10月9日,中国“嫦娥二号”绕月探测卫星完成了第三次近月制
On October 1, 2010, at 18:59:57, the Xichang Satellite Launch Center in China launched a roar of earth. The lunar satellite Chang’e II took the Long March No.3 carrier rocket and rushed to the sky directly to the distant 380,000 km of the moon. Is the first time that China successfully used the rocket launch technology to directly send satellites into the Earth-Moon transfer orbit. “The Chang’e II satellite made an orbit correction midway along the orbit to the Earth and Moon. When the satellite reached a specific position near the moon, The implementation of the first brake in recent months, access to the nearest point of 100 km, 12-hour lunar elliptical orbit.Then after two near-point brake, into the altitude of 100 km round moon work track.On October 9, China ”Chang’e II " round the moon exploration satellite completed the third near month
