Interstellar messages are sent by laser array.

星际信息将由激光发送。

Oh, sure you do. Now, see, what's this here in the schematic? Is that a laser array? Yes. No. Hmm!

别逞强了。等下，瞧示意图上这是什么？是激光列阵吗？对。不。

It only uses the reflection of light from this very large laser array to propel the spacecraft.

它只利用这个非常大的激光阵列反射的光来推动航天器。

You do not leave the laser array that produces the light on for the entire journey.

在整个旅程中，您都不要让产生光的激光阵列保持打开状态。

But we'd need a giant, square laser array that's 10 kilometers long on each side -- which presents some obvious problems.

但我们需要一个每边长 10 公里的巨大方形激光阵列——这会带来一些明显的问题。

The team's plan -- assuming NASA chooses to move forward with their idea -- is to start with a laser array that's only one meter square.

该团队的计划——假设美国宇航局选择推进他们的想法——是从一个只有一平方米的激光阵列开始。

That laser array technology is a whole project all by itself, called the Directed Energy System for Targeting of Asteroids and exploRation, or DE-STAR, and being developed by the same research team.

激光阵列技术本身就是一个完整的项目，称为小行星瞄准和探索的定向能系统，或 DE-STAR， 由同一个研究团队开发。

In our case, we're creating an artificial wind in space from this laser array, except the wind is actually the photons from the laser itself, the light from the laser becomes the wind upon which we sail.

在我们的例子中， 我们正在用这个激光阵列在太空中制造人造风，除了风实际上是来自激光本身的光子， 来自激光的光变成了我们航行的风。

With a huge laser array putting out 50-70 gigawatts of power, a 100 kilogram ship -- about the size of Voyager 1 -- could travel at around 1.5% of the speed of light -- nearly 300 times Voyager's top speed.

一个巨大的激光阵列输出 50-70 吉瓦的功率，一艘 100 公斤重的船——大约相当于航海者一号的大小——可以以大约 1.5% 的光速行进——几乎是航海者号最高速度的 300 倍。
