失重情况下喵星人会怎么表现

What The Heck Are These Cats Doing In Zero-G?!

这里是DNews 我们喜欢太空
Here at DNews, we love space.
我们也喜欢猫
And we love cats.
所以我们应该讨论下猫在太空中的情况了
So it’s about time we talk about cats in space!
嘿所有地球上的笨蛋们 跟着DNews一起探索吧
Hey all you earthbound suckers, Trace here for DNews.
现在我们要做些与众不同的当我们在网上闲逛时 发现
Today, we’re doing something a little different: while poking around on the internet, we found
这个科学视频我们看不懂
this science video that we could not figure out.
在这些实验中你会发现动物会失去方向感当突然被放置
In these experiments you can see the disorientation resulting when an animal is suddenly placed
在失重的环境中
in a weightless state.
看完这个我们要问:这个录像从哪里来
After watching that, we had to find out: where did this footage come from?
这些失重的猫接下来会怎样
And what is going on with those weightless cats?
这个答案可以追溯到美国宇航局存在前
Well, it turns out the answer stretches back to before NASA even existed.
这些猫至今仍影响着我们的太空计划
And those cats are still affecting our space program today.
这场太空竞赛开始于1957年 因为第一颗人造卫星 苏联Sputnik1的发射
The space race began in 1957 with the Soviet launch of Sputnik 1, the very first man-made satellite.
顺便说 这是Sputnik1绕着地球运行的真实声音
That’s the actual sound of Sputnik 1 while orbiting the Earth, by the way.
Sputnik点燃了美国去太空的野心 不超九个月 美国宇航局成立了
Sputnik lit a fire under the US to get to space, and within 9 months, NASA was up and running.
但事实证明 就太空研究而已NASA并不是最好的
But it turned out,NASA was’t the only game in town when it came to space research.
美国军队一直在研究极限飞行对飞行员的影响
The American military had been studying the effect of the extreme flight on pilots
从第一次世界大战起
since World War I.
他们知道如果我们要打败俄罗斯人去太空 我们需要明白
And they knew that if we were going to beat the Russians to space, we’d need to understand
人体对重力变化有什么反应……像火箭
how the human body responded to changes in gravity…like the huge g-forces of a rocket
发射的巨大重力或轨道的失重环境
launch or the macro-gravity environment of orbit.
我们怎么在50年代学习新且危险的事情
And how did we study new and dangerous things in the 50s?
还有动物
With animals.
这是一个1952年的火箭测试 NASA成立前5年
Here’s a rocket test from 1952, five years before NASA was founded.
火箭上有两只菲律宾猴子和两只白色老鼠
Onboard were two Philippine monkeys and two white mice.
他们变成在火箭飞行过程生存的最早一批动物 而且那给了
These animals became some of the very first to survive a rocket flight, and that gave
我们一些最早的关于极端重力和零重力的资料
us some of our earliest data on both extreme g-forces and macro gravity.
真是超勇敢的火箭猴子
Brave, brave rocket monkeys.
但无论如何
But anyway.
1985年 NASA的短期目标是让一个美国人进轨道
In 1958, NASA comes online with the immediate goal of getting an American into orbit.
但是他们没有条件去进行所有实验
But they don’t have the facilities or scale to conduct all the experiments they want to conduct.
所以在1961年 逐渐出现了一个叫航空航天医学部的空军部门 或叫AMD
So in 1961, in steps an Air Force department called the Aerospace Medical Division, or AMD.
他们和NASA一起实验使水星航天项目
They work with NASA on experiments designed to get the Project Mercury spaceflight program
成功
up to snuff.
还有一些很高强度的测试
And there are some pretty intense tests.
这是AMD试着为战斗机加弹射椅
Here’s the AMD trying out an ejection seat for a fighter jet:
主降落伞开始打开 但在这个特殊的测试中它部分倒塌了
“The main parachute starts to deploy, but in this particular test, it collapsed partially.
受试者受到冲击 大概在16.5G时失去意识
The subject received an opening shock, estimated at 16.5 G, and lost consciousness.”
AMD对人进行了大部分实验 但 你懂的……他们也要
The AMD ran most of their tests on humans, but, you guessed it…they’re also responsible
为这个录像负责
for this video.
为了研究没有真正送进轨道的失重动物 AMD把
In order to study weightless animals without actually sending them into orbit, AMD loaded
猫 鸽子装进货机然后让它自由下落
cats, and also pigeons, into a cargo plane and sent it into a controlled free fall…
看 零Gs
voila, zero Gs.
60年以后……再来看 互联网黄金时代来临
And 60 years later… double voila, internet gold!
但到底在货机里挣扎的猫能体现人类在太空里是什么样吗
But what on Earth can kicking cats around a cargo plane teach us about humans in space?
嗯 很多
Well, a lot, actually.
1961年 AMD发表了一篇教人们在
In 1961, the AMD published a paper that described techniques to help people rotate themselves
零重力条件下漂浮时旋转的论文
while floating in zero gravity.
像这样的实验告诉我们“弯曲” “套索”和 呃
Experiments like these taught us: the “Bend and Twist,” the “Lasso,” and, wait for
……“猫反射”
it…the “Cat Reflex.”
看起来和这很像
Which looks a lot like this.
重点是:像如何在太空移动自己的身体这样基本的东西并没有直接体现
The point is: basic things like how to move your own body are not intuitive in space.
但通过从自然中学习 科学家们能教我们的宇航员们怎样在轨道中生存和超越
But by copying nature, scientists taught our astronauts how to survive in orbit, and beyond.
因为NASA和空军辛勤地工作 我们现在才有科学家
So thanks to a lot of hard work by NASA and the Air Force, we now have footage of floating
逗猫的录像
scientists juggling cats.
你的税在起作用
Your tax dollars at work.
……鸽子 尽管……我们仍然不知道有什么卵用
…The pigeons, though… we still have no idea what that’s all about.
So what do you guys think?
这是交税带来的杰作吗?来看看评论 多多订阅DNews哦
