宇宙值多少钱?

How Much Money Is Space Worth?

大家好!
Hey there!
欢迎来到Life Noggin
Welcome to Life Noggin.
太空已经教会我们探索许多有关于恒星、宇宙
Space exploration has taught us a lot about
甚至是我们星球的知识
the stars, our universe, and even our own planet.
但是太空是否能让你们变得富有吗?
But what if space could make you rich?
有许多出现在宇宙中的元素是在地球上十分珍贵的
There are some elements up in space that are very valuable here on Earth.
许多元素被发现在小行星内部并且价值数亿乃至上万亿美金
Many are found inside asteroids and could be worth billions or trillions of dollars
如果我们能开采它们
if we could mine them.
当中最珍贵的是铂族的金属 它在地球上很稀有但是很重要
The most expensive are platinum-group metals, which are rare on Earth but necessary for
对高科技设备和电子产品
high-tech devices and electronics.
科学家认为一些小行星蕴藏的铂矿远超所有
Scientists think that some asteroids contain more platinum-group metals than are in all
地球上的存量
the Earth’s reserves.
一个15年经过地球的小行星可能蕴藏九千万公吨的
One asteroid that passed us in 2015 likely contained 90 million metric tons of these
金属矿藏 价值高达五万亿美金
metals… worth up to 5 trillion dollars.
你还能在某些小行星上找到铁、镍、钴
You can also find iron, nickel, and cobalt in certain asteroids.
但最珍贵的东西是水
But the most valuable item might be water.
运送水到太空里真的很贵 仅仅16盎司的水就要花费惊人的
It’s really expensive to ship water up to space — just 16 ounces costs a whopping
2500美元
2500 dollars.
假如在大气层之上有一个稳定的水源 这将有很多用处
If there was a reliable source up above the stratosphere, it would have a lot of uses.
对于太空站里的制冷系统来说 水是必要的
Water is necessary for the cooling systems on the International Space Station, and it
并且它有可能被用于为宇航员提供辐射防护
could potentially be used as a radiation shield for astronauts.
但是最合算的方法是将水分解成氢气和氧气…火箭燃料的
But the most lucrative use is to split it into hydrogen and oxygen… the basic elements
基本元素
of rocket fuel.
这将把一个含水的小行星变成燃料补给站
This would essentially turn a water-filled asteroid into a space gas station, allowing
允许飞船填充燃料和更远地航行
vehicles to refuel and venture farther away.
另一个潜在水源地是我们的邻居月亮
Another potential source of water is our neighbor, the moon.
此外月亮上还有别的珍贵元素
And the moon has other valuable elements as well.
月亮上蕴藏氦3 它在地球上极其稀少
It contains Helium 3, which is extremely rare on Earth but could potentially be used in
但能被用于核聚变反应 假如我们能利用核聚变来造福地球
nuclear fusion reactors, if we can get fusion to work on our planet.
月球的全部资源被估计在150到500
The total value of the moon’s resources has been estimated at between 150 and 500
千的五次方美金
QUADRILLION dollars.
是的 千的五次方!
Yep, QUADRILLION.
尽管太空采矿很困难 这还是有一定可能性的 而且有几个公司
Although space mining isn’t easy, it’s definitely possible, and several companies
当前就在努力找出怎样实现它的办法
are currently working out how to do it.
一个小行星的引力不足以让一艘宇宙飞船停留 因此目的就变成了让飞船停留
An asteroid’s gravity is too weak to hold down a spacecraft, so the goal is to dock
就像飞船停在太空站里
with it like a vehicle docks with the Space Station.
然而真正的挑战是找到有开发价值的小行星
The real challenge is to figure out which asteroids are worth going to.
地球附近大约有1500个小行星 但它们都很昏暗
There are roughly 1500 candidates nearby, but they can be faint and hard to detect from
并且很难从地球观测
Earth.
红外线技术帮助我们了解那些小行星的构成,但是很难判断
Infrared technology helps tell us what’s them, but it’s difficult to know if the
这些数据是否精准
readings are accurate.
尽管一个小行星的引力不够强 但它还是能对宇宙飞船造成混乱
Also, even though an asteroid’s gravity isn’t strong, it can still mess with spacecraft.
不像圆圆的月球 小行星形状不规则
Unlike the round moon, asteroids have irregular shapes, making their gravitational pull vary
这让它们的引力随你在的位置而变化
depending on where you are.
绕过这些“驼峰”得花些功夫
Getting around these “humps” will take some work.
尽管如此 一个公司认为在大约2027年
Still, at least one company thinks that they will be extracting water from asteroids by
能从小行星提取出水
about 2027.
并且美国航空航天资源勘探代表团想第一个开发月球
And NASA’s Resource Prospector mission wants to be the first to mine the moon, with the
随着2020年代初登陆计划的希望
hopes of launching a craft in the early 2020s.
不管他们能否成功 已经有不少直接因为太空而产生的利益
Whether or not they’re successful, there’s still money to be made indirectly from space.
许多本为了航空而开发的技术已经在日常生活中
Many of the technologies developed for space programs have had other uses in our daily
有了其他用途
lives.
美国航空航天的进步引领了许多技术 诸如智能手机摄像、记忆海绵、MRI和CAT扫描
NASA’s advancements have led to smartphone cameras, memory foam, MRI and CAT scans, and
甚至还有婴儿食品中的一种重要添加剂
even a key ingredient in infant formula.
因此如果你想在太空赚钱 最好的方法就是呆在
So if you want to make money off space exploration, maybe the easiest way is to just stay here
地球
on Earth.
你认为我们应该在太空采矿吗?
Do you think we should mine in space?
它有价值吗?
Is it worth it?
