Hey there, Welcome to Life Noggin.
大家好，欢迎来到脑洞大开的生命奇想。
Space travel has given us a lot more than just some pretty pictures of Mars and a few footprints on the moon.
太空旅行带给我们的不仅仅是火星和月球脚印的一些漂亮照片。
It's taught us so much about the universe, shifted our perspective and changed how we live here on Earth.
太空旅行教会了我们很多关于宇宙的东西，改变了我们的视角，改变了我们在地球上的生活方式。
But what if we never traveled to space?
但是如果我们从来没有去过太空呢？
You may not realize it but there's a lot of things we use in our day to day lives that might not be around if we hadn't ventured out into the unknown.
你可能没有意识到，如果我们没有冒险进入未知世界，我们日常生活中使用的很多东西，可能就不会出现。
There's one set of pretty basic space tech that we definitely take for granted here on Earth. Satellites.
有一套非常基本的太空技术，我们在地球上肯定认为是理所当然的。就是卫星。
The area surrounding Earth is full of satellites from various space agencies like NASA, JAXA and the ESA.
地球周围布满了来自美国国家航空和宇宙航行局(NASA)、宇宙航空研究开发机构（JAXA）和欧洲航天局（ESA）等各种航天机构的卫星。
These under-appreciated heroes give us GPS navigation, more detailed storm warnings and cosmic weather forecasts, which sounds really cool.
这些默默无闻的英雄为我们带来GPS导航，详细的风暴警告和宇宙天气预报，听起来真的很酷。
GPS relies on real-time satellite data that streams down to GPS receivers. No satellites, no GPS.
GPS依赖于实时的卫星数据，这些数据会传到GPS接收器。没有卫星，就没有GPS。
Imagine having to use maps to get around! Real maps! No, thank you.
想象一下，你出门得拿着地图！真正的地图！不了，谢谢。
In a world without satellites, a lot of extreme storms like hurricanes and tornadoes wouldn't be forecast at all!
没有卫星的话，很多像飓风和龙卷风这样的极端风暴根本无法预测！
They'd just come out of nowhere, taking unsuspecting lives and causing more damage to unprepared areas.
它们会不知从哪里冒出来，在人毫无防备的情况下，危害生命，造成重大损失。
Without satellites, we wouldn't be ready for geomagnetic storms either.
如果没有卫星，我们也没办法应对地磁暴。
These are when radiation from the sun hurdles towards Earth threatening our global electrical power systems.
地磁暴发生时，来自太阳的辐射冲击地球，威胁到我们的全球电力系统。
Satellites send storm warnings to Earth, allowing the electric power industry to prepare and avoid massive outages.
卫星向地球发送风暴警报，使电力行业能够做好准备，避免大规模停电。
In just 3 years, these warnings are estimated to have saved about $450 million.
在短短3年的时间里，这些警告估计已经节省了4.5亿美元。
If we never sent those satellites up there, you'd be in for a lot of candlelit, no-wifi nights.
如果我们不把卫星送上去，你就会经历很多没有wifi的烛光之夜。
Without advances made in the space industry, air travel would be more time-consuming and expensive too.
如果没有航天工业的进步，航空旅行也会更加耗时和昂贵。
NASA created the backbone of modern air traffic control, and without it, you'd better believe it'd take us a lot longer to get up into the sky.
NASA创造了现代空中交通控制的支柱，如果没有它，我们要花更长的时间才能到达天空。
NASA engineers figured out that turning the tips of the plane wings upward reduces drag, saving airlines billions in fuel costs.
NASA的工程师们发现，将机翼的尖端向上翻转可以减少阻力，从而为航空公司节省数十亿美元的燃油成本。
We can also thank space travel for countless breakthroughs in the field of medicine.
我们还要感谢太空旅行为医学领域带来的无数突破。
JPL, the Jet Propulsion Laboratory, played a lead role in developing the digital imaging technology that's now used for CAT scans and radiography!
喷气推进实验室喷气推进实验室(JPL)在数字成像技术的开发中发挥了主导作用，该技术目前应用于CAT扫描和放射学！
So many illnesses and broken bones would go undiagnosed without this tech! You know that memory foam mattress you sleep on?
如果没有这项技术，那么许多疾病和骨折将无法诊断！你知道你的记忆泡沫床垫是怎么来的吗？
Well, you got that thanks to NASA's advances in space travel and spending a Saturday afternoon at Bed Blocko & Beyond.
好吧，这要归功于美国宇航局在太空旅行方面的进步，以及周六下午在Bed Blocko & Beyond公司度过的时光。
Wireless headphones? NASA. Tech to ensure clean drinking water? ESA. Safe land mine removal? ESA & NASA.
无线耳机？NASA发明的。清洁饮用水的技术？ESA发明的。安全清除地雷？ESA和NASA发明的。
Futuristic self-driving tractors? Yes, you heard that right. NASA.
未来无人驾驶拖拉机？是的，你没听错。NASA发明的。
And also there are a bunch of foods we wouldn't have without space travel either.
还有一些食物，如果没有太空旅行，我们也不会有。
Space travel has done even more than all that. Space travel feeds the curiosity of so many of us stuck here on Earth.
太空旅行所做的甚至比所有这些还要多。我们被困在地球上，太空旅行激发了我们的好奇心。
It's taught us so much about space, like that the universe is expanding, that it's 14 billion years old, and about what it looked like 10 billion years ago.
它教会了我们很多关于太空的知识，比如宇宙在膨胀，它有140亿年的历史，以及它100亿年前是什么样子的。
It's taught us so much about our planet too, like the long-term implications of global warming, changing ocean and weather patterns, and our atmosphere.
它也教会了我们很多关于地球的知识，比如全球变暖的长期影响，海洋和天气模式的变化，以及我们的大气层。
Space travel is crazy expensive and whether or not it's worth the money is heavily debated.
太空旅行非常昂贵，是否物有所值还存在很大争议。
So do you think it's worth it? Let us know in the comments section below.
你觉得值得吗？请在下面的评论部分告诉我们。
And if you enjoyed this space video, then you should probably check out the video we did on whether we can or cannot live on the moon.
如果你喜欢这个太空视频，那么你应该看看我们做的，关于我们能否在月球上生活的视频。
These solar rays can do some serious damage to our fragile human bodies, especially during solar storms when the moon's surface can be hit with hundreds of rems of radiation.
这些太阳射线会对我们脆弱的人体造成严重的伤害，尤其是在太阳风暴的时候，月球表面会受到数百雷姆的辐射。
As always, my name is Blocko. This has been Life Noggin. Don't forget to keep on thinking.
我是宝高，这里是脑洞大开的生命奇想。思考不要停！
