But now the thinking is

但現在的想法是

these pockets of water, some no bigger than a penny, could be much more common on accessible than we previously thought.

這些一坑坑的水，有的不比一分錢大，可能比我們之前想象的更常見。

Tens of billions of potential ice reservoirs on the moon.

月球上有數百億個潛在的冰庫。

And so this expands greatly the potential reservoirs of water that could be accessed for both scientific and exploration purposes.

是以，這極大地擴大了可用於科學和勘探目的的潛在水庫。

Scientists say that one day humans could be drinking this water, using it to grow food or splitting its molecules to make rocket fuel to help us travel deeper into space.

科學家說，有朝一日，人類可以飲用這種水，用它來種植食物，或者將其分子分裂成火箭燃料，幫助我們深入太空。

The moon is a lot smaller than here on Earth.

月球比地球上小很多。

Gravity is a lot less so.

重力就沒有那麼大了。

It's actually more economical for us to launch missions from the surface of the moon than it would be from Earth, and this could be happening before the end of the century.

實際上，對我們來說，從月球表面發射任務比從地球發射更經濟，這可能在本世紀末之前發生。

But what does the surface of the moon look like right now?

但現在月球表面是什麼樣子的呢？

Mountains, valleys, storm and volcanoes and planes of solidified lava.

山脈、山谷、風暴和火山以及凝固的熔岩平面。

You can't step on the moon without treading on a crater.

踏上月球就會踩到火山口。

That's because it's constantly being bombarded by things like asteroids and meteoroids and comets on.

那是因為它不斷地被小行星、流星體和彗星等東西轟炸。

They've been hitting the moon for billions of years because the moon has no atmosphere.

他們已經撞擊月球幾十億年了，因為月球沒有大氣層。

Once a mark is made, almost nothing can remove it.

一旦做了記號，幾乎沒有任何東西可以消除它。

And then let's not forget about all the things humans have left behind.

然後我們不要忘記人類留下的所有東西。

Over the years we are explorers were looking to go live on the moon and on do a lot of science there that we couldn't achieve on the short emissions of, say, the Apollo era on.

這些年來，我們是探險家都想去月球上生活，在那裡做很多科學，我們無法實現的短排放，比如說，阿波羅時代的上。

Then hopefully you use the moon, a za launchpad, to take us onwards deeper into the solar system to Samar's.

那麼希望你利用月球這個za發射臺，帶著我們繼續深入太陽系，前往薩瑪爾的。
