Wow! Very interesting stuff but every time I see something interesting, I have more questions than answers. For example, what happens to the fluid in your body? If it floats around, won't we die???

#52That was amazing. On a side note, and not complaining about this at all, how much did it cost to get that water to the space station? I guess that bag had maybe 300 ml?
I remember reading that water is generated as a byproduct of the hydrogen fuel cells on board. And then the water vapour is also recycled and repurified back into the system. So it's a closed water system powered by solar energy inputs. Of course, the machinery necessary for this loop costs x billions, but the particular molecules of water used in this experiment probably came out of the internal water cycle and didn…

So there is still some loss of water even with the recycling

Tissues can be hanged somewhere on a clip, water evaporates, is picked up by dehumidifiers of the spaceship, goes back to the water system and purified back into drinking water.
I guess they meant getting the drinking water to the space station in the first place. Water doesn't really compress well (unlike the hockey puck rag) and also weighs quite a bit so sending it up should be pretty costly.
Hydrogen and Oxygen compress though, and are combined into water in the station's fuel cells.

#54Just floats his mic. No mic stand required. Not sure why that blows my mind. Driving home that he'd in freaking orbit. Something I "know", but is hard to comprehend.

I was wondering when they return to Earth, do they ever just let go of things thinking it will float...? Out of habit I mean.

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.
Once you have the experience of trying to get a baby wipe out at 3am while a baby is crying, you'll realize they already come pretty close to vacuum sealed. :)
Not just crying but legs kicking and hands trying to grab their own poo while you try and open a bag of wipes. I think you need 5 arms to handle that situation.

yeah, his Google+ feed is amazing. all this expeditions are very expensive and serious, and meanwhile he's like "hey, lets make it fun for everybody down there who's curious. oh hai from space, here's a photo of your city and cool tricks with no gravity".
huh. let me cite a speech I heard recently (celebration of 10 years of columbus module in space).. (approximately, it's from my mind) .. "The ISS hat two mission objectives, (I) to bring the international community together for collaboration and friendship - this has been accomplished very well, and (II) to do some meaningful science up there, which has not been accomplished at all as of yet. Thus, it's your job to i…
Well, there's a lot of science done at the ISS.
They're usually running between 100-150 "experiments" at any given time. Most of these do meaningful science. As we all should know, research and science doesn't always lead to something tangible though, but even in the cases it doesn't, it tells a lesson.
Wikipedia lists some of them, http://en.wikipedia.org/wiki/Scientific_research_on_the_Inte..., and just few weeks ago, results from the AMS (http://en.wikipedia.org/wiki/Alpha_Magnetic_Spectrometer) provided some of the most tangible measures we have of dark matter.

Haha. It's recently gotten worse at nearly 3yo, because he's much stronger and thinks playing with poo is funny. I've mastered the art of several wrestling holds, could probably go pro.
