卫星进入周期为12小时、近月点210千米、远月点8600千米的月球椭圆轨道。The orbiter traveled along a 12-hour elliptical moon orbit,with a perilune—the point in a lunar orbit that is nearest to the moon—of about 210 km and an apolune—the point in a lunar orbit that is farthest from the moon—of about 8600 km.
探测器进入月球轨道后，必须作几次制动，才能成功被月球引力所捕获，成为绕月卫星。制动过早，卫星会飞离月球，制动过晚，就会与月球相撞。After the probe enters the moon’s orbit,it will brake several times so that it will be captured by lunar gravity and become a real circumlunar satellite. It would fly away from the moon if the braking is too early,or crash into the moon if the braking is too late.
第三次近月制动将卫星的速度减至每分钟1.59千米、轨道调整为周期127分钟的极月圆轨道。The third braking further slowed the probe’s speed to 1.59 km.per second to enter a 127-minute round polar circular orbit.
经过326个小时、总距离约180万千米的长途飞行和四次变轨、一次轨道调整和三次制动后，卫星成功进入月球的“工作轨道”。After completing a 326-hour long journey of some 1.80 million kilometers,four orbital transfers,one orbital correction and three brakings,the satellite successfully entered the moon’s “working orbit”.
科学目标：获取月球表面三维影像，分析月球表面有用元素及物质类型的含量和分布，探测月球风化层特性，探测40万千米间的地月空间环境。The scientific objectives include:to acquire 3-D images of lunar surface;to analyze abundance and distribution of elements on lunar surface; to investigate characteristics of lunar regolith; and to explore space environment between the Earth and the Moon.
