That would reveal much about the lunar orbit and that data could in turn be used to test some of the tantalizing ideas in einstein ' s theories 这就可以揭示许多关于月球轨道的奥秘。这些数据继而又可以用来检验爱因斯坦理论中一些令人困扰捉摸不透的概念，

After an elementary study with lunar orbiting satellite , it is necessary to make exploration devices land on the moon and carry out detailed exploration with lunar rover in a rather large area 在利用环月卫星对月球进行初步的探测之后,需要使探测器在月球表面软着陆,并由月球车执行较大范围的详细探测任务,为载人登月和建立月球基地做好准备。

It is because the plane of the lunar orbit does not coincide with the plane of the earth s orbit . so , for most full moons , the moon is either south or north of the orbital plane of the earth 原来月球的公转轨道平面和地球的公转平面并不一致，因此在满月时，月球通常不是在地球轨道平面之南，就是在其北，难得会进入位于轨道平面的地影内，所以大部分满月都不会出现月食。
