Which is out of orbit, not where it should be.

它沒在軌道上 沒在該在的地方

This engine, which we will ultimately use to return the astronauts from earth's orbit to the earth's surface and also in later missions to put the astronauts into lunar orbit and bring them back home from lunar orbit, will then have its first flight test.

這個(gè)引擎最終的作用 是將宇航員從地球軌道送回地表 并且在之后的任務(wù)中 把宇航員送進(jìn)月球軌道 再從從月球軌道返程 引擎將進(jìn)行首次飛行測(cè)試

Genzel knew that measuring the star's orbit could tell him about whatever it was orbiting.

格瑟爾知道測(cè)量這個(gè)星的軌道 可以告訴他 它在繞著什么運(yùn)行

A planet orbits a star, but its orbit is divided between two universes, ours and another.

行星繞恒星公轉(zhuǎn) 但行星軌道被分在 兩個(gè)宇宙中 我們的宇宙和另一個(gè)宇宙

But then, because some of the fragments are thrown into higher orbits and some are thrown into lower orbits, the speed is different.

但是之后 因?yàn)橛行┧槠?被投入高處軌道 一些進(jìn)入低處軌道 速度不同了

Coming up on the lunar orbit insertion burn, in which the spacecraft will start its initial orbit around the moon.

即將點(diǎn)燃主火箭進(jìn)入月球軌道 屆時(shí)航天器將先繞月球軌道運(yùn)行

If you thrust, itit actually slows you down, because it puts you into a higher orbit, so you have to reduce thrust and drop into a lower orbit in order to catch up.

如果推進(jìn) 那會(huì)減慢你的速度 因?yàn)槟菢幽銜?huì)進(jìn)入更高的軌道 所以你就得減少推進(jìn)力 進(jìn)入更低的軌道 才能進(jìn)入

Once you know the size of a star's orbit and the time it takes to go round, it's a relatively simple calculation to work out the mass of the object it's orbiting.

一旦你知道了星星軌道的尺寸 和它繞軌道一周的時(shí)間 可以相對(duì)簡單地計(jì)算出 圍繞運(yùn)行天體的質(zhì)量

There are thousands of objects in orbit.

在軌道上有成千上萬的物體

I'm so lucky that I fell into your orbit.

我如此幸運(yùn)地進(jìn)入了你的生活軌道
