我国月球探测卫星的飞行过程将主要分为三个阶段:(1) 调相轨道段:月球探测卫星与运载火箭分离后,将先围绕地球运行一段时间。通过三次近地点变轨,逐步抬高轨道的远地点。在第三次变轨后(11),卫星脱离地球轨道,进入奔向月球的地—月转移轨道。(2) 地—月转移轨道段:地—月转移轨 China’s lunar exploration satellite flight process will be mainly divided into three phases: (1) phase modulation orbit: moon exploration satellite and launch vehicle separation, will first run around the earth for some time. Change the orbit by three near perigee and gradually raise the apogee of the orbit. After the third change of orbit (11), the satellite detaches itself from Earth’s orbit and enters the lunar-earth-moon transfer orbit. (2) Earth-Moon transfer orbit: Earth-Moon transfer orbit
