| Voyager 1 here is flying by Titan at |
旅行者1号掠过土卫六的速度 |
| I think it's 38,000 miles per hour. |
我记得是3万8千英里每小时 |

| Voyager 1 as it flies by Saturn. |
旅行者1号飞过土星的画面 |
| There's a point to be made here. |
这里有一点我需要说明 |
| With a 3D visualization like this, we can not only just say Voyager 1 flew by Saturn. |
凭借这样的一个三维可视化程序 我们不仅可以简单地展示旅行者1号飞过土星 |
| There's a whole story to tell here. |
这里包括了这个过程的所有细节 |

| It actually flies underneath Saturn. |
它实际上是从土星的下面飞过 |
|
underneath:prep.在…的下面;在…的支配下;n.下面;底部;adj.下面的;底层的;
|
| Now, what happens is, as it flies underneath Saturn, |
现在,随着旅行者1号从下方飞过土星 |
| Saturn grabs it gravitationally and flings it up and out of the solar system, so if I just keep letting this go, you can see Voyager 1 fly up like that. |
进入土星的重力场后,旅行者1号受其引力被向上抛出 离开了太阳系 所以如果我让画面继续 你就可以看到旅行者1号的轨迹是这样的 |

|
| And, in fact, I'm going to go back to the solar system. |
接着了,让我们重新回到太阳系 |
| I'm going to go back to today, now, and I want to show you where Voyager 1 is. |
我把时间调回今天,此时此刻 我想向大家展示旅行者1号现在在哪 |
| Right there, above, way above the solar system, way beyond our solar system. |
就在这,太阳系的上方,遥远的上方 离太阳系很遥远了 |
| And here's the thing. Now you know how it got there. |
所以,现在你就知道了旅行者1号是怎么到达那里的 |
| Now you know why, and to me, that's the point of this program. |
你也知道了其中的奥妙,对于我来说 这就是这个程序的意义所在 |

|
| Well, we're trying to give you the solar system in your grasp — (Laughter) — and we hope once it's there, you'll be able to learn for yourself what we've done out there, and what we're about to do. |
我们想要做的了就是 把太阳系至于你的掌控之中——（笑声）—— 我们希望大家能利用这个程序 学到点什么东西 能够了解我们做了些什么,我们即将要做些什么 |
| And my personal dream is for kids to take this and explore and see the wonders out there and be inspired, as I was as a kid, to pursue STEM education and to pursue a dream in space exploration. |
我个人的梦想了,是希望孩子们能够利用它 发现和探索宇宙中的奥妙 并能因此获得激励,就像我还是孩子的时候 受到鼓舞投身于科学、技术、工程、数学之中 投身于空间探索之中 |
| Thank you. (Applause) |
谢谢 |
