The " Three-Body Problem" is a complex issue in celestial mechanics.

“三体问题”是天体力学中的一个复杂问题。

Its design takes advantage of lunar microgravity, the use of local resources and the complex celestial mechanics that operate on the south pole of the moon.

它的设计利用了月球微重力、当地资源的使用以及在月球南极运行的复杂天体力学。

This nocturnal launch, dictated by the vagaries of celestial mechanics, gave rocket-watchers a rare treat, as the vehicle's white-hot exhaust lit up the countryside for miles around.

由于天体力学的变幻莫测，这种夜间发射给火箭观察者带来了难得的享受，因为火箭白热的废气照亮了方圆数英里的乡村。
