I would watch Nova on PBS.

在小的時候，我就對航空及太空的事物十分著迷。

Our school would show Bill Nye the Science Guy.

我會看公共電視網播放的 Nova 節目。

When I was in elementary school, my next door neighbor,

我們學校也會放映的 "比爾教科學" (由迪士尼製作的一個科學節目)

he gave me a book for my birthday.

小學的時候, 隔壁鄰居

It was an astronomy book,

在我生日時送了我一本

and I poured over that thing for hours on end,

有關天文的書，

and it was a combination of all these things

我花了好幾個小時一口氣把它看完,

that inspired me to pursue space exploration

就是這些經歷

as my own personal dream, and part of that dream was,

對太空的探索

I always wanted to just fly around the solar system

成為了我的夢想, 而其中一個，

and visit different planets and visit moons and spacecraft.

就是飛遍太陽系,

Well, a number of years later, I graduated from UCLA

拜訪不同的星球，參觀各個衛星及太空飛行器。

and I found myself at NASA,

幾年後，我從加州大學洛杉磯分校畢業

working for the jet propulsion laboratory,

進入了美國國家航空暨太空總署，

and there our team was challenged

在噴氣推進實驗室裡工作

to create a 3D visualization of the solar system,

而我們的團隊, 正思索著

and today I want to show you what we've done so far.

能否創建一個三度空間視覺化的太陽能系統，

Now, the kicker is, everything I'm about to do here

今天, 我要向您們展示我們現階段所做出的成果。

you can do at home, because we built this

而且, 我在這裡所展示的

for the public for you guys to use.

您們在家裡都可以自己操作，因為我們建立的目的

So what you're looking at right now is the Earth.

就是讓大眾都能輕易使用。

You can see the United States and California

現在各位看到的是地球。

and San Diego, and you can use the mouse

可以看到美國和加州

or the keyboard to spin things around.

聖地牙哥. 您可以使用滑鼠

Now, this isn't new. Anyone who's used Google Earth

或鍵盤輕易的旋轉。

has seen this before, but one thing we like to say

使用過 Google Earth 的人

in our group is, we do the opposite of Google Earth.

都知道如何的操作，但我們團隊所做的

Google Earth goes from this view down to your backyard.

和 Google Earth 是完全相反

We go from this view out to the stars.

Google Earth 是將視野透視到每個家的後院。

So the Earth is cool, but what we really want to show

而我們則是從地球向外拉出去看各個宇宙中的星球。

are the spacecraft,

這個地球是很酷，但我們真正想要展示的

so I'm going to bring the interface back up,

是太空飛行器，

and now you're looking at a number of satellites

現在我獎調節接觸面

orbiting the Earth.

然後, 你們會看到幾個衛星，

These are a number of our science space Earth orbiters.

正繞著地球飛行。

We haven't included military satellites and weather satellites

這裡有些科學人造衛星。

and communication satellites and reconnaissance satellites.

我們還沒將軍事衛星和氣象衛星涵蓋進來

If we did, it would be a complete mess,

也沒有通信衛星和偵察衛星。

because there's a lot of stuff out there.

如果將它們全數納進來，這系統將會顯得非常混亂，

And the cool thing is, we actually created 3D models

因為實在太多了。

for a number of these spacecraft, so if you want to visit

最酷的是，我們確實的創建了某些飛行器的 3D 模型

any of these, all you need to do is double-click on them.

因此，如果您想要更仔細的它們,

So I'm going to find the International Space Station,

只需要按兩下划鼠就可以了.

double-click, and it will take us all the way down to the ISS.

假設我想找國際太空站，

And now you're riding along with the ISS

找到它, 按兩下，馬上就到那兒去了。

where it is right now.

而且就跟著它此時此刻所在的位置

And the other cool thing is, not only can we

一起飛行。

move the camera around, we can also control time,

另外一件很酷的事是，我們不只可以

so I can slide this jog dial here

左右移動相機，還可以控制時間，

to shuttle time forward, and now

我現在在這選項裡

we can see what a sunset on the ISS would look like,

將時間往後拉,

and they get one every 90 minutes. (Laughter)

就可以看到在國際空間站的日落是什麼景象

All right, so what about the rest of it?

而且每隔90分鐘就可以有一個日落。（笑聲）

Well, I can click on this home button over here,

好吧，那還有什麼呢？

and that will take us up to the inner solar system,

按一下主頁按鈕，

and now we're looking at the rest of the solar system.

這將帶我們到太陽系內部，

You can see, there's Saturn, there's Jupiter,

我們看到了太陽系的其他星球。

and while we're here, I want to point out something.

有土星，木星

It's actually pretty busy.

在這裡，我想說明的是

Here we have the Mars Science Laboratory

這是個很忙碌的銀河系。

on its way to Mars, just launched last weekend.

這個是上個星期才發射,

Here we have Juno on its cruise to Jupiter, there.

正航向火星的科學實驗室

We have Dawn orbiting Vesta,

這個是正航向木星的 Juno 號.

and we have over here New Horizons

我們的曙光號繞著灶神星 (Vesta)

on a straight shot to Pluto.

這裡是新視野號

And I mention this because

正航向冥王星

there's this strange public perception that

我提到這些是因為

NASA's dead, that the space shuttles stopped flying

大眾有個奇特的認知，

and all of the sudden there's no more spacecraft out there.

以為美國國家航空暨太空總署已死，太空梭已不再發射

Well, a lot of what NASA does is robotic exploration,

或突然之間所有的太空飛行器都不見了。

and we have a lot of spacecraft out there.

目前美國國家航空暨太空總署都是用機器人探索，

Granted, we're not sending humans up at the moment,

而且已經送出很多這樣的太空飛行器了。

well at least with our own launch vehicles,

我們不再將人類送至外太空，

but NASA is far from dead,

至少 NASA 不再如此做了.

and one of the reasons why we write a program like this

但 NASA 不會這麼輕易的結束的

is so that people realize that there's so many other things

我們寫這個程式的原因之一

that we're doing.

就是因為人們意識到

Anyway, while we're here, again,

我們還在著手進行很多其它的研究。

if you want to visit anything,

好, 現在回到這個程式,

all you need to do is double-click.

如果您想要造訪任何行星衛星，

So I'm just going to double-click on Vesta,

您只需對著它按兩下划鼠。

and here we have Dawn orbiting Vesta,

現在我找到灶神星，按兩下

and this is happening right now.

就可以看到曙光號環繞灶神星

I'm going to double-click on Uranus, and we can see

而且這是現在這個時刻正在進行的事。

Uranus rotating on its side along with its moons.

現在對著天王星，按兩下，我們看到

You can see how it's tilted at about 89 degrees.

天王星以及它的衛星群的運轉情形

And just being able to visit different places

您可以看到它們是呈 89 度傾斜。

and go through different times,

我們可以造訪不同的地點

we have data from 1950 to 2050.

也可以進入不同的時空

Granted, we don't have everything in between,

因為這系統擁有 1950 到 2050 年的資料

because some of the data is hard to get.

當然，我們沒有所有的時空的詳細資料，

Just being able to visit places in different times,

因為某些資料真的很難取得

you can explore this for hours,

因為可以在不同的時空裡造訪這個太陽系,

literally hours on end,

您大概得花上幾個小時

but I want to show you one thing in particular,

才能瀏覽完畢

so I'm going to open up the destination tab,

現在我要特別展示一下

spacecraft outer planet missions, Voyager 1,

現在我要打開目標選項欄

and I'm going to bring up the Titan flyby.

選擇: 外太空衛星任務，旅行者一號

So now we've gone back in time.

然後再叫出泰坦星球

We're now riding along with Voyager 1.

所以現在我們回到了那個時空

The date here is November 11, 1980.

我們現在正在與旅行者一號同行。

Now, there's a funny thing going on here.

日期是 1980 年 11 月 11 日。

It doesn't look like anything's going on.

現在，有趣的是

It looks like I've paused the program.

它看上去像沒事一樣

It's actually running at real rate right now,

就好像我暫停了程序。

one second per second, and in fact,

但它實際上是以一個速率在行進的

Voyager 1 here is flying by Titan at

事實上，

I think it's 38,000 miles per hour.

旅行家一號正在飛往泰坦星

It only looks like nothing's moving because, well,

速率應該是每小時 38,000 英里

Saturn here is 700,000 miles away,

它看起來不像在移動的樣子

and Titan here is 4,000 to 5,000 miles away.

那是因為, 土星離這裡是 700,000 英里，

It's just the vastness of space makes it look like nothing's happening.

泰坦星則離這裡 4,000 至 5,000 英里遠。

But to make it more interesting,

因為距離太遙遠, 因此感覺不到有任何的動靜

I'm going to speed up time, and we can watch

為了使它更有趣，

as Voyager 1 flies by Titan,

我把速度加快， 我們可以看到

which is a hazy moon of Saturn.

旅行者一號正通過泰坦星

It actually has a very thick atmosphere.

它是一個土星的矇矓的衛星。

And I'm going to recenter the camera on Saturn, here.

實際上，它有很厚的大氣層。

I'm going to pull out, and I want to show you

並且我要把中心設為土星

Voyager 1 as it flies by Saturn.

然後將鏡頭拉出去，

There's a point to be made here.

您就會看到旅行者一號正飛行過土星

With a 3D visualization like this,

我要說明的是

we can not only just say Voyager 1 flew by Saturn.

利用這樣的三度空間視覺化系統

There's a whole story to tell here.

我們不僅僅可以了解旅行者一號飛過了土星

And even better, because it's an interactive application,

更可以明白在背後的故事

you can tell the story for yourself.

更棒的是，它是一個互動式應用程式

If you want to pause it, you can pause it.

您可以讓它為您說故事。

If you want to keep going, if you want to change

可以依您的需要隨時的暫停, 繼續

the camera angle, you can do that,

如果您想更改相機角度

and because of that, I can show you

隨時都可以這麼做的

that Voyager 1 doesn't just fly by Saturn.

因此，我可以告訴您

It actually flies underneath Saturn.

旅行者一號不只是飛向土星。

Now, what happens is, as it flies underneath Saturn,

它實際上是從土星的下方飛過

Saturn grabs it gravitationally and flings it up

現在, 當它從土星底下飛過, 發生了一件事

and out of the solar system,

土星的地心引力抓住了它

so if I just keep letting this go,

並把它往上扔出了太陽系

you can see Voyager 1 fly up like that.

所以如果我只是讓它繼續延著這路徑走，

And, in fact, I'm going to go back to the solar system.

您會看到旅行者一號往上飛了起來。

I'm going to go back to today, now,

現在我要回到太陽系裡

and I want to show you where Voyager 1 is.

回到今天，現在，此時此刻

Right there, above, way above the solar system,

我會指出旅行者一號在哪裡

way beyond our solar system.

就在哪兒，在太陽系的上方

And here's the thing. Now you know how it got there.

在離太陽系很遠很遠的地方

Now you know why, and to me,

現在您明白了它是如何到那裡的

that's the point of this program.

對我來說，

You can manipulate it yourself.

這也是設計這個程式的主要目的

You can fly around yourself and you can learn for yourself.

您可以自己操縱它

You know, the theme today is "The World In Your Grasp."

您可以任意的飛，也可以幫助自己學習

Well, we're trying to give you

今天的主題是"掌握世界"。

the solar system in your grasp — (Laughter) —

我們試圖給您的

and we hope once it's there,

則是 "掌握的太陽系" — — （笑聲） — —

you'll be able to learn for yourself

我們希望可以藉由這個系統

what we've done out there, and what we're about to do.

您能夠自我學習

And my personal dream is for kids to take this

也能更瞭解我們做了什麼，我們將要做什麼

and explore and see the wonders out there

我個人則是希望, 能藉此啟發孩子們

and be inspired, as I was as a kid,

去探索外太空的奇妙宇宙

to pursue STEM education

像我孩提時的經歷一樣

and to pursue a dream in space exploration.

追求科學,技術,工程和數學 (STEM) 教育

Thank you. (Applause)

並繼續探索太空的夢想。
