A similar phenomenon makes it dangerous to sleep without proper ventilation: >It is important that crew accommodations be well ventilated; otherwise, astronauts can wake up oxygen-deprived and gasping for air, because a bubble of their own exhaled carbon dioxide has formed around their heads. http://en.wikipedia.org/wiki/International_Space_Station#Cre...
This sounds like the exact opposite of fan death.

I was really suprised to see them in the original package. One would think they had applied some form of vacuum sealed pressured bag or something to minimize space, or had special designed wipes with material that’s light weight. I guess not everything up there is special space stuff. Some of it is just the same stuff as in the local Grocery store.
Reminds me of that famous anecdote where NASA invested a million in developing a pen that could write in zero G, while the Russians used a pencil.

Because it's real?

#84I thought just watching the microphone float in front of him was interesting enough. I was totally not prepared for the awesomeness of the wrung-out washcloth.
When astronauts come back to earth, do they have some adjusting period where they keep dropping items on the floor because they forget about gravity?

I always wonder, if you spend a length of time in space, you must get used to being able to leave an object in mid air, go do something, and go back and pick it up later. When astronauts come back to earth, do they have some adjusting period where they keep dropping items on the floor because they forget about gravity?
If I'm ever allowed to be a space tourist, I suspect I'd spend hours just trying to get something to stop drifting relative to the cabin. And then play with water.

TV makeup is split into two types, 1) getting people looking good (same reason people wear makeup any time - but if you're being filmed, more people will see you, so you care more) 2) preventing the shine While it's true that the lighting often doesn't help, the biggest problem is that the lighting can produce a lot of heat, so it's actually the lights making people sweat, not just making sweat show up more. Not sure…
Alexandr Laveikin (cosmonaut) spent time on the Mir (Мир) spacestation in 1987. He said it was "very noisy, very hot." (This is from 'Packing for Mars' by Mary Roach) I guess heat conduction is difficult if your spacecraft is in a vacuum.
Very much so. Search for "heat" in this SVG and you'll see the giant accordion radiators: http://upload.wikimedia.org/wikipedia/commons/a/aa/Iss027e03...
When the Space Shuttle was in orbit, it kept its giant bay doors open to expose its radiators.
If you'd like, I can dig up some extensive articlage written for hard sci-fi writers about dealing with heat for engines and for life support.

#88Does anyone else here find it amazing that NASA paid to send a fullsize wireless microphone into space. Given the cost per kilogram of sending things into space, I'm surprised they didn't go with something much smaller/lighter.
Can you imagine a wired mic in zero g? Given how easily headphones etc tangle in gravity, I'd hate to see what they could do IN SPACE.

I would feel wary sending anything smaller, lest it get stuck or lost in some nook somewhere and caused problems. Besides, part of CSA's mandate is to "advance the knowledge of space through science", and sending up cameras and microphones is well within that mandate. http://www.asc-csa.gc.ca/eng/about/mission.asp

#90I did a talk yesterday with one of those headset radio mics, and all through that video I kept thinking "I want a floating microphone next time". No matter what you say, a floating microphone will hold the audience :-)
I wonder whether, after he returns to Earth, Cmdr Hadfield will expect things to hang in the air for him; looks habit-forming.
