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)行首次飛行測試

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

格瑟爾知道測量這個星的軌道 可以告訴他 它在繞著什么運行

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 兩個宇宙中 我們的宇宙和另一個宇宙

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 因為有些碎片 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.

即將點燃主火箭進(jìn)入月球軌道 屆時航天器將先繞月球軌道運行

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) 那會減慢你的速度 因為那樣你會進(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間 可以相對簡單地計算出 圍繞運行天體的質(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.

我如此幸運地進(jìn)入了你的生活軌道
