  • The Apollo Spacecraft was the incredible machine that

    阿波羅太空船是讓太空人

  • allowed astronauts to walk on the moon.

    得以登上月球的神奇載具

  • It was split up into 3 parts

    它總共分成三個部分

  • the Command Module, the Service Module

    包括指揮艙、服務艙

  • and the Lunar Module.

    以及登月艙

  • Later on, we'll talk about what each module does,

    我們稍後將介紹每個艙別的功用

  • but first, let's talk about the launch vehicle that gets us into orbit.

    但首先,要來談談將太空船送上軌道的發射載具

  • The Saturn Five rocket.

    也就是農神五號火箭

  • Each mission was launched from

    每次的阿波羅任務都是從位於佛州的

  • Cape Canaveral in Florida.

    卡拉維爾角發射

  • Mission Control was all the way in Houston, Texas.

    任務控制中心則位於德州休士頓

  • The Saturn Five rocket was 363 feet tall.

    農神五號火箭高達363英尺

  • Just to get a good size comparison,

    為了更好理解它的大小...

  • here's the size of a person,

    這是一個人的大小

  • and here is the size of a Boeing 747.

    而這是一架波音747的大小

  • The Saturn Five was split up into 3 stages;

    農神五號火箭共分為三節

  • they referred to each stage by a technical name.

    每一節都有個各自的名稱

  • The first stage was called the S-1C

    第一節叫做S-IC

  • and was powered by five F1 rocket engines.

    它是由五具F-1火箭發動機推動

  • The second stage was called the S2, and was powered

    第二節叫做S-II,它是由五具

  • by five, slightly smaller, J2 rocket engines.

    較小的J-2火箭發動機所推動

  • The third stage was called the S-4B and was powered

    第三節叫做S-IVB,動力來源

  • by only one J2 rocket engine.

    則是一具J-2火箭發動機

  • The actual spacecraft, was stored up at the top of the

    真正的太空船則是安裝在

  • rocket stages.

    各級火箭的頂端

  • Here is the Lunar Module, which would actually land on

    這是實際執行登月任務的

  • the Moon.

    登月艙

  • During the launch, it was protected by four panels,

    發射時,它是由四片稱為

  • known as the spacecraft Lunar Module adapter.

    「太空船登月艙結合器」的外板所保護

  • The Service Module contain the engines necessary to

    服務艙裝載著進出月球軌道所需的

  • enter and leave lunar orbit as well as fuel cells

    火箭發動機和燃料電池

  • and other electrical components.

    以及其他的電子組件

  • The Command Module is where the 3 astronauts spent

    指揮艙則是三位太空人航程中

  • most of their time.

    所待最久的艙室

  • At the very top, you'll find the Launch Escape System.

    而在火箭的最頂端則是發射逃生系統

  • In the event of an emergency, it would carry

    它能在緊急狀況下讓指揮艙安全地

  • the Command Module safely away from the rocket.

    脫離火箭本體

  • The structure you see next to the Saturn Five

    位於神農五號火箭旁邊的結構物

  • is called the Launch Umbilical Tower.

    叫做「發射塔」

  • You'll notice there are 9 service arms that provide

    還能看見上面共有九根橫臂

  • access to the Saturn Five.

    讓工作人員能夠接近農神五號火箭

  • On the day of the launch, the 3 astronauts ride an

    在發射當日,三位太空人

  • elevator to the top service arm.

    將搭乘電梯到達最上方的橫臂

  • The White Room is where they enter the Command Module.

    「無塵室」是他們進入指揮艙的地點

  • Four of the service arms are moved out of the way

    其中四根發射前橫臂(preflight arms)

  • before the launch.

    會在發射前就移開

  • The First Stage ignites 8 seconds before the Saturn Five

    第一級會在農神五號火箭升空前

  • leaves the ground.

    八秒點火

  • As the Saturn Five starts to rise,

    當農神五號火箭開始升空時

  • the remaining 5 service arms quickly rotate to get out of

    剩下的五根發射中橫臂(inflight arms)

  • the way.

    才會快速移開

  • It takes about 12 seconds for the rocket to completely

    火箭本體要花12秒才能

  • clear the tower.

    完全脫離發射塔

  • As the Saturn Five picks up speed,

    當農神五號火箭開始加速時

  • the astronauts will feel as much as 4 G's, or 4 times

    太空人會承受高達4G的重力

  • the amount of gravity pressing them into their seats.

    也就是自身體重四倍的力量壓著他們

  • The First Stage shuts off at 2 minutes 42 seconds

    第一級發動機會在2分42秒後關斷(OECO)

  • at a height of about 42 miles.

    這時的高度約是42英里

  • Explosive bolts detonate releasing the first stage,

    爆炸螺栓會起爆使第一級脫離

  • letting it to fall back down to the Atlantic Ocean;

    並讓它自由落下至大西洋中

  • shortly after, the second stage fires up.

    而第二級緊接著馬上點燃

  • We're high enough in the atmosphere now, that the

    這時火箭的高度已經夠高

  • Launch Escape System is no longer needed.

    所以發射逃生系統已經不再需要(LET)

  • The second stage shuts off at 9 minutes and 12 seconds

    第二級會在發射後9分12秒關斷(OECO)

  • at a height of 109 miles.

    這時的高度是109英里

  • The third stage fires up for a short amount of time

    第三級火箭發動機短暫點燃一段時間

  • to get the astronauts into a Parking Orbit

    將太空人送進高度118英里的

  • of 118 miles.

    停駐軌道

  • We'll talk more about the Parking Orbit in the next video.

    我們將在下一部影片介紹停駐軌道

  • It shuts off at 11 minutes and 39 seconds, but does not detach yet.

    第三級火箭在發射後11分39秒關斷,但暫時不會脫離本體

  • One of the hardest parts of the mission is over, but the adventure doesn't stop here.

    任務最困難的階段之一已經結束,但冒險才正要開始

  • Please join me in part two, as we continue our journey towards the Moon.

    歡迎收看第二部影片,我們將繼續前往月球的旅程
