条条大路通月宫

     目前,把绕月探测卫星从地面发射到月球轨道有多种方式,常用的有4种:第1种是用运载火箭先将绕月探测卫星送入近地球的圆轨道上,然后靠绕月探测卫星自行加速进入地月转移轨道到达月球:第2种是用运载火箭将绕月探测卫星送入环地球飞行的大椭圆轨道,然后通过绕月探测卫星在椭圆轨道的近地点处加速来进入地月转移轨道,最终到达月球;第3种是用运载火箭将绕月探测卫星送入地月引力平衡点处,然后在地月引力平衡点处使绕月探测卫星加速进入月球轨道:第4种是用运载火箭把绕月探测卫星直接送入地月转移轨道从而飞向月球。

       以上4种方式在过去的探月活动中都使用过,它们各有特点。根据嫦娥1号的使命和性能以及我国现有运载火箭的能力,经过精确的分析和计算,为了用最小的代价实现奔月过程,我国绕月探测卫星选择了第2种轨道飞行方式。

      飞往月球需要多长时间呢?事实上,不同的月球探测器飞抵月球的时间是不一样的。地月距离最近时为363300公里,最远为405500公里。但从地球发射的载人飞船或月球探测器都不会走直线距离,而是按大椭圆轨道飞向月球。

       1959年1月2日发射的人类第一颗月球探测器——苏联的月球1号是从地球直接飞往月球并从月球上空近6000公里处飞过,用了不到2天的时间。

       到达月球耗时最长的要算欧洲空间局的斯玛特1号月球探测器,它采用了一种称为离子推进系统的先进技术,经多次变轨,在太空中巡游了一年零两个月才进入环月轨道

       我国嫦娥1号探测器在飞往月球的过程时,先由长征3号甲运载火箭送人环绕地球运行一周半的16小时的地球轨道,经过轨道机动进入运行周期24小时的轨道,然后通过再次机动进入48小时轨道,在此过程中逐渐抬高轨道高度,最后离开地球进入奔月轨道并飞往月球。飞行110多个小时后到达近月点。并且还要经过3次减速机动后,最终进入200公里的圆轨道,所以嫦娥1号飞抵月球的时间大约需要12天。
