00:00:00.045 --> 00:00:06.156
Now, in this week's Art of Movement, we're looking at something that has gone where no man-made object has ever gone before.
在本週的《動的藝術》節目裡，我們要看看有個東西跑到了人造物體不曾到過的地方。

2
00:00:06.485 --> 00:00:14.095
Now, NASA's Voyager has finally exited our solar system and it's still sending back crucial information about our universe.
美國太空總署的「航海家號」終於飛出了我們的太陽系，而且仍然不斷傳回有關宇宙的重要資訊。

3
00:00:26.206 --> 00:00:30.004
It's been on a 37-year trip deep into space.
這艘太空船往深遠的太空飛行了三十七年。

4
00:00:31.873 --> 00:00:38.052
NASA's unmanned spacecraft, Voyager, has traveled farther than anyone or anything in history.
美國太空總署的無人太空船航海家號所飛行的距離，是歷史上任何人或物從未能及的。

5
00:00:38.354 --> 00:00:43.038
The primary mission for Voyager was to fly by Jupiter and Saturn.
航海家號的首要任務是飛經木星與土星。

6
00:00:43.465 --> 00:00:45.337
But Voyager went beyond this mission.
不過，航海家號超越了這項任務。

7
00:00:45.600 --> 00:00:53.838
It has been the only spacecraft to fly by Uranus or Neptune and has no plans to stop, having already journeyed billions of kilometers.
它是唯一飛經天王星與海王星的太空飛行器，而且還不打算停下來，至今已飛行了數十億公里。

8
00:00:54.148 --> 00:01:01.608
Voyager took advantage of alignment of the outer planets, which are Jupiter, Saturn, Uranus and Neptune,
航海家號利用外行星——木星、土星、天王星與海王星——排成一直線的時候，

9
00:01:02.059 --> 00:01:06.434
to be able to go by all four of those planets within a 12-year period.
才能在十二年間飛過全部這四顆行星。

10
00:01:06.719 --> 00:01:10.718
Now, that alignment of planets only happens every 176 years.
行星排成那樣的一直線每一百七十六年才會出現一次。

11
00:01:13.745 --> 00:01:19.683
The brilliant images Voyager sends back to Earth are the only true window this far into our universe,
航海家號傳回地球的壯觀影像，是至今為止唯一能夠讓我們真正窺見宇宙這麼遠處的窗口，

12
00:01:20.111 --> 00:01:27.014
providing fascinating new information about our solar system all from a spacecraft designed almost 40 years ago.
關於我們太陽系的新資訊相當引人入勝，全都由將近四十年前設計的太空飛行器提供。

13
00:01:27.757 --> 00:01:30.023
Voyager was launched in 1977,
航海家號於一九七七年發射，

14
00:01:30.034 --> 00:01:37.322
so the technology that are on each of the Voyager spacecraft are vintage '70... early '70s to '75.
所以每一艘航海家號太空飛行器上的科技都是古早的七○年……從七○年代初期到七五年間的產物。

15
00:01:37.762 --> 00:01:42.246
Vintage technology, like only having around 70 kilobytes of memory.
古早的科技，例如記憶體容量只有七十 KB（七萬位元組）左右。

16
00:01:42.726 --> 00:01:48.693
A 16-gigabyte iPhone 5 has more than 240,000 times that amount,
一支十六 GB（一百六十億位元組）的 iPhone 5 手機記憶體容量超過航海家號的二十四萬倍，

17
00:01:49.034 --> 00:01:52.054
but some of Voyager's features have proven to be timeless.
但事實證明航海家號有些規格歷久不衰。

18
00:01:52.562 --> 00:01:58.975
Its fault-protection technology allows the spacecraft to fix itself without getting commands from Earth.
它的故障保護科技使它不必接收來自地球的指令也能夠自我修復。

19
00:01:59.338 --> 00:02:04.392
The fault-protection technology that Voyager had on board has been improved,
航海家號上的故障保護科技已經有所改進，

20
00:02:04.752 --> 00:02:08.995
but has been flown on every spacecraft since Voyager.
而自航海家號以降的每一架太空飛行器都搭載了這項技術。

21
00:02:09.365 --> 00:02:12.506
And instead of an endless supply of energy carried on board,
此外，航海家號也沒有搭載無窮無盡的能源供應，

22
00:02:12.860 --> 00:02:19.947
Voyager helps fuel itself using the pull of gravity to essentially slingshot from planet to planet.
而是藉由引力來提供自身動能，基本上是從一顆行星拋往另一顆行星。

23
00:02:20.538 --> 00:02:28.049
And now Voyager is heading toward new discoveries, already moving past the edge of our solar system into interstellar space.
現在，航海家號正朝向新發現前進，已經飛出我們這個太陽系的邊緣，進入了星際空間。

24
00:02:28.519 --> 00:02:33.037
What that means is that Voyager has traveled outside of the bubble of our sun.
也就是說，航海家號已經飛到我們這個太陽的泡泡之外。

25
00:02:33.445 --> 00:02:43.462
The data that Voyager 1 is sensing now is data from other stars and from supernova eruptions and the remnants of stars that have exploded over the course of history.
航海家一號現在偵測到的資料，都是來自其他恆星、超新星噴發以及過去爆炸的恆星所留下的殘骸。

26
00:02:43.947 --> 00:02:47.969
The art of getting this data back to Earth takes time and precision.
將這種資料傳回地球的技術需要時間與精確度。

27
00:02:48.455 --> 00:02:54.011
Now, Voyager is now so far from Earth that commands take more than 17 hours to reach it.
現在，航海家號距離地球已非常之遠，以致從地球上發出的指令要十七個小時以上才會送達。

28
00:02:54.248 --> 00:02:58.338
But it may be much longer before the spacecraft encounters any other planets.
不過，航海家號恐怕還要很長一段時間才會再遇到其他行星。

29
00:02:58.586 --> 00:03:07.705
It's gonna take us 40,000 years to come within three light years of the next nearest sun or the next nearest star.
我們要花上未來四萬年才能到達離我們最近的下一顆太陽或恆星三光年以內的距離。

30
00:03:07.871 --> 00:03:09.443
And that's a long, long time.
那可是一段非常、非常久的時間。

31
00:03:10.179 --> 00:03:15.017
But if there's anything out there, Voyager will be the first to let us know.
不過，如果外太空有任何東西，航海家號絕對會率先讓我們知道。
