CNN News:NASA慶祝首次太空行走50周年

Speaking of satellites, NASA is celebrating an anniversary this week. It`s been 50 years since the first U.S. spacewalk was made.

說起人造衛(wèi)星，美國宇航局本周正在慶祝紀念日。自美國首次太空行走至今已經(jīng)有50年了。

Since then, there had been more than 260 strolls into space. Most of them had been done to work on the International Space Station, part of its estimated $75 billion to the U.S. But many of the astronauts who`ve taken a spacewalk would call it priceless.

直至現(xiàn)在，太空行走已達260多次。大多數(shù)發(fā)生在國際空間站上，其中一些對美國的的價值估計達750億美元。但是許多在太空行走的宇航員認為，太空行走是無價的。

ED WHITE, NASA ASTRONAUT: OK, I`m out.

埃迪·懷特，美國宇航局宇航員：我出艙了。

CONTROL: OK, now

控制室：好，現(xiàn)在......

REPORTER: They were the first American boots to step into space. NASA astronaut Ed White left the hatch of Gemini IV 50 years ago this week, strapped to a tether 250 miles high above the Earth. Twenty-three minutes later, White returned to the spacecraft which he would later described as one of the saddest moments of his life.

記者：他們是首次踏入太空的美國靴子。美國宇航局航天員埃迪·懷特于50年前的今天離開了雙子座4號太空載人艙(GEMINI IV)的艙口，系著繩子進入了離地球250英里的高空范圍內(nèi)。23分鐘后，懷特返回了太空艙。之后，他描述到返回太空艙是自己生命中最悲傷的時刻之一。

MICHAEL FOREMAN, NASA ASTRONAUT: Going outside, when you have that full panoramic view through your helmet, is just amazing.

邁克爾·福爾曼，美國宇航局宇航員：進入太空，透過頭盔，可以看到看景，那種感覺很神奇。

REPORTER: Soviet cosmonaut Alexei Leonov did it first. American Ed White`s mission came three months later. But it was White who proved that productive work could be done outside a spacecraft.

記者：前蘇聯(lián)宇航員阿列克謝·列昂諾夫首次完成太空行走。三個月后，美國宇航員埃迪·懷特也獲得了同樣的任務(wù)。但是，是懷特證明了宇宙飛船外能進行生產(chǎn)性工作。

That paved the way to this.

那是太空行走為這項工作打下了基礎(chǔ)。

NEIL ARMSTRONG, NASA ASTRONAUT: It`s one small step for man, one giant leap for mankind.

尼爾·阿姆斯特朗：這是我個人的一小步，但卻是人類的一大步。

REPORTER: NASA astronauts had performed hundreds of spacewalks since Neil Armstrong`s famous moon landing.

記者：自從尼爾·阿姆斯特朗著名的登月后，美國宇航員又完成了數(shù)百次太空行走。

ASTRONAUT: Once we get that mike, we`re going to go ahead and verify our

宇航員：一旦我們拿到麥克風(fēng)，我們將會向前去核實......

REPORTER: Michael Foreman has done five of them, spending more than 32 hours in zero gravity.

記者：邁克爾·福爾曼完成了5次，在失重的情況下呆了32小時。

FOREMAN: You`re not 100 percent how you`re going to feel until you experience that for the very first time.

福爾曼：只有第一次經(jīng)歷過那種感覺，你才會完整。

Fortunately for me, I felt very comfortable out there and it was just like muscle memory took over when I went out that hatch the very first time because I was just so used to doing the same thing here in the training that we had in the pool.

幸運的是,我出艙后，沒有不適感。我第一次出艙后，就像肌肉記憶起作用。因為在我只是在做我們平時在泳池訓(xùn)練時一樣的事情。

ANNOUNCER: Now, one hour and three minutes into today`s spacewalk.

今天太空行走時間增加了63分鐘。

REPORTER: In 1973, when Skylab was damaged, repairs were made to the solar panels in space to keep it in orbit.

記者：1973年，當太空實驗室Skylab受損時，太陽能板得到修復(fù)以保持實驗室在軌道上正常運行。

During 1980s, astronauts began using jet packs to fix satellites and carry out repairs.

在20世紀80年代，宇航員開始采用太空噴氣背包修復(fù)衛(wèi)星并進行其他維修。

ASTRONAUT: Sounds great, Dan. A great effort all around.

宇航員：不錯，Dan，付出了很大的努力。

REPORTER: It took five back to back spacewalks to repair and upgrade the Hubble telescope.

記者：連續(xù)進行了5次太空行走來修理和升級哈勃望遠鏡。

ASTRONAUT: All right. (INAUDIBLE) adjustable rather goes down.

宇航員：好的，……是可調(diào)節(jié)的但不要降低。

REPORTER: Space walks are almost routine, part of the building and maintenance of the International Space Station, which orbits the Earth at more than 17,000 miles an hour.

記者：太空漫步幾乎都是常規(guī)工作，部分工作是建設(shè)和維護國際空間站。國際空間站以每小時1.7萬英里(約合27350公里)的速度繞地球軌道飛行。
