国际空间站的Wifi SSID是什么？What is the International Space Station’s Wifi SSID?
That’s top secret. I can tell you, but I’d have to kill you…
Just kidding, but actually it really is a secret. We keep the SSID confidential to make it harder for someone to hack the LAN onboard. (Not that a Quora reader would ever do something so vile, of course.)
只是开玩笑，但实际上这确实是个秘密。 我们对SSID保密，以使别人更难破解空间站LAN。 （当然，并不是说Quora读者会做些卑鄙的事情。）
I can tell you that is a very mundane SSID. Nothing cute like ‘Hal’.
我可以告诉你，这是一个非常普通的SSID。 没有什么像“ Hal”那样可爱。
你在太空中最想念的是谁？What earthbound thing did you miss the most while you were in space?
That’s easy – my wife, Simone.
Once a reporter asked me that question near the end of my 95 days aboard the International Space Station. I replied that while I often gaze out the window at the billions of people below, I am usually thinking about only one of them.
That reporter called me “The Most Romantic Astronaut” and it led to a lot of teasing from my fellow astronauts who were worried about the standard I was setting. It also made Simone very embarrassed, although she found a way to forgive me.
The NY Daily News even wrote an article about it. You can read it here:
NASA astronaut Garrett Reisman is out of orbit, into love
And if you are wondering what I missed the second-most, that’s also easy – pizza!
你来到空间站外的时候是什么感觉？How does it feel to go outside of the International Space Station?
Doing a spacewalk was the most exciting as well as the most challenging part of both of my space missions. The best way that I can describe the experience, other than “AWESOME!!” would be to say that it is a strange combination of the familiar and the outlandish.
进行太空行走是我两次太空任务中最激动人心，也是最具挑战性的部分。 除了“真棒！”之外，我可以描述体验的最佳方式！ 可以说这是熟悉的和古怪的组合。
What I mean by that is that you have done so much preparation for this event that many aspects feel perfectly normal. Your suit fits just like the ones you have worn on Earth; the switches are all in the same place and the glove fits like, well… When you get to the worksite, the bolts and electrical connectors are all in the same place as they were in the big pool that we use for training in Houston. Your tools all work the same way and even the Space Station looks very familiar.
我的意思是，您已经为这次活动做了大量准备，很多方面都已经感觉不错。 你的宇航服就像在地球上穿的衣服一样合身。 开关就在平时训练时的那个地方，手套也很合适……当您到达工作地点时，螺栓和电连接器，都和我们在休斯顿训练所用的大游泳池训练时那样都在同一个地方 。 您的工具都以与在地面上相同的方式工作，甚至空间站也看起来非常熟悉。
Then you look out and see the entire east coast of the United States go flying on by – and that is totally outlandish!
I’ve always wanted to ask this question to an astronaut – do you feel like Superman when you are space walking?
A little bit. Not that you feel like you are actually flying, but with your head in a giant glass fishbowl of a helmet it’s almost like there is nothing between you and the universe. Those scenes in the Superman movies where he flies above the atmosphere and just kind of hovers above the Earth for a moment – it’s kind of like that.
一点点。 您并不觉得自己实际上正在飞行，而像是把头放在巨型玻璃鱼缸中，然后您似乎融进了宇宙。 但在超人电影中，场景通常是他飞过大气层，然后在地球上方徘徊片刻-就像那样。
宇航员在太空中能听到什么声音？What sounds do astronauts hear during a spacewalk?
Mostly what you hear is the sound of the pumps and fans that circulate air and water through your suit. It’s not terribly annoying or anything, but it’s not the silent lonely environment with no sound other than your own breathing like often depicted in the movies.
Plus you are wearing a headset so you have the sound of your crewmates and the folks in Mission Control talking to you fairly regularly.
It is true, however, that sound cannot travel in a vacuum so you do not hear things outside. When you drive a bolt or tap a piece of equipment with a tool, you don’t hear a thing.
One interesting thing that happens is that when you put your crewmates in the airlock to perform an EVA and then shut the hatch, at first you can hear a bunch of clanging as their metal tools softly strike the other equipment, handrails, or the hull of the small airlock. Then as you depress the airlock it still looks exactly the same through the hatch window. But now the clanging sound is gone. You can see their equipment bumping into stuff as before, but now it is silent.
As an EVA is in progress, you can hear the spacewalkers bumping and clanging along as your crewmates translate on the exterior of your module. It sounds kind of like ghosts in the attic dragging chains. Although without the scary moaning sounds!
And one more thing – as Stephen Colbert and I proved, it is true that in space, no one can hear you scream. Check out my profle for the link to our interview so you can see for yourself!

These are some of the sounds recorded by astronaut Chris Hadfield while on the ISS:
Also, NASA just put up a soundcloud page. It’s got voice & radio transmission recordings, launch sounds, solar system sounds, and some others. How *DID* that “NASA, we have a problem” quote really go???
