let's talk about the Lunar Module a little more.

The Descent Stage got us safely to the surface,

「降落級」能讓我們平安降落到月面

but now it's dead weight and will be left behind

The Ascent Stage has it's own propulsion system, which

is what gets the two Astronauts safely back into orbit.

兩位太空人就要靠著它安全返回軌道

Don't forget about our one lonely Astronaut, who's still

What I'm about to explain is called Rendezvous and Docking.

我接著要解釋的是「會合」與「對接」

I'm going to change the Moon's scale here,

我現在要稍微改變一下月球比例

Lift off, will need to happen at just the right time.

This gets us initially back into Lunar Orbit.

Several short engine burns happen over the next

It takes almost two orbits before Docking can happen.

必須要繞行幾乎兩圈軌道後，才能開始對接

On later Apollo Missions, they were able to do this in

不過在後來的阿波羅任務中，太空人能在

all valuables are transferred to the Command Module.

所有重要物資都被轉移到指揮艙中

It's time to say goodbye to the LM Ascent Stage;

it was either left floating in Lunar Orbit,

不是把它留置在月球軌道上漂流

this is very similar to what we've done before.

這階段和我們之前的操作很類似

On the far side of the Moon, the Service Module Engine

服務艙的火箭發動機在月球背面

fires up for about two and a half minutes.

This is called the Trans-Earth Injection.

這階段被稱之為「逾地軌道嵌入」(TEI)

It was a three day journey to get back home.

接著要花三天時間慣性飛行至地球

Remember that the Service Module contains things like

This means that all three Astronauts are in the

這代表三位太空人在這段旅程中

Command Module for the remainder of the journey.

We started with the giant Saturn Five Rocket

任務一開始是龐大的農神五號火箭

and now the Command Module is the only part

而任務執行到現在，只剩下指揮艙

The climax of the whole mission is called Re-entry.

整趟任務的最後高潮就是「重返大氣層」

All this time the Service Module was protecting

what's on the bottom side of the Command Module,

Re-entering the Earth's atmosphere is dangerous

重返地球的大氣層是一項危險任務

The Heat Shield protects the Command Module for

防熱板能夠在指揮艙穿越大氣層時

several minutes as it passes through the atmosphere.

Down below, an Aircraft Carrier waits for the

海面上，兩棲突擊艦(LPH)正等待著

Once we get about two miles above the surface,

一旦指揮艙距海面兩英里高度時

the parachutes are deployed to slow us down even more.

減速傘就會開啟，讓降落速度進一步降低
