Left to themselves, the majority of satellites eventually tumble out of orbit.

如果任其发展，大多数卫星最终都会脱离轨道。

All celestial bodies exert a gravitational force on nearby objects, pulling them in and out of orbits.

所有天体会对附近的物体施加引力，将它们拉入和拉出轨道。

All the ships head in… out of orbit.

所有的飞船都驶入… … 脱离轨道。

You'll knock it out of orbit!

你会把它从轨道上撞下来!

But for now, the U. S. government is more focused on preventing new debris from forming than taking the trash out of orbit.

但就目前而言， 美国政府更注重防止新碎片的形成， 而不是将垃圾带出轨道。

A system of three stars— like Alpha Centauri— could come crashing into one another or, more likely, some might get flung out of orbit after a long time of apparent stability.

一个由三颗恒星组成的系统——比如半人马座阿尔法星——可能会相互碰撞，或者更有可能的是， 在长时间的表面稳定之后， 有些恒星可能会被抛出轨道。

It was the first spacecraft shot directly out of orbit, escaping the pull of the Earth and Sun with a launch velocity of over 16 kilometers per second, the fastest spacecraft launch ever.

这是第一艘直接射出轨道的航天器，以超过每秒 16 公里的发射速度摆脱了地球和太阳的引力，是有史以来最快的航天器发射。

But every action has an equal and opposite reaction, so in zero-G, scientists had to figure out some way to counterbalance this rotating camera so that it wouldn't also rotate the satellite straight out of orbit.

但是每个动作都有一个相等和相反的反应，所以在零重力下，科学家们必须想办法平衡这个旋转的相机，这样它就不会把卫星直接旋转出轨道。
