ISS space bio-experiment freezer to return on Discovery Consumer pundits have long speculated that we would one day - perhaps even by now - have intelligent fridges which could be remotely controlled and monitored from afar using advanced communications links. But they couldn't realise that these fridges would become crammed with possibly-deadly organisms warped by extraterrestrial …
Loyd is correct about the temperature in space near earth as such. I can't find a source for a good figure near the earth, but cooling was a significant issue for Apollo 13. Substantial cooling will occur simply from radiation in space, so an area away from the heating support systems for any vehicle in space will cool substantially. What it this doesn't take into account is transport to and from the surface of the earth, and for that part of the journey both substantial insulation and cooling would be required. (Although I've never understood the desire to bring potentially deadly materials back to earth. Far better to study them in space where if something goes hideously wrong you can try to contain it, maybe even launch it into the sun.)
Oh, and the sun doesn't freeze because the gravitational energy of the sun keeps it in a plasma state in which nuclear fusion occurs, which also adds to the temperature of the sun.
Yeah, I was an astro major a long long time ago, although I eventually gave it up because arithmetic and I don't get along.
One last note, conduction via metal is the most efficient heat transfer mechanism. Which means that a box attached to an array of metal fins that radiate the heat away would actually be the fastest means to transfer heat away in space.
"Aliens live in our Earth's atmosphere"
For the first time in human history, I present here incontrovertible evidence of existence of tens of thousands of UFO in the Earth's atmosphere, which can be seen by any person in any part of the world at any time...

Do you spuds not understand irony? You'd think that the Fantastic Four reference might have hinted at a lack of seriousness but apparently not.
And by the way, it's a double L, like the bank or the insurance company or the chemist or the gym or the Prime Minister or the composer, in fact like everything famous with the same name except Grossman who's a septic and thus doesn't count. *sigh*
...with this fridge of bio-death in tow lets damned well hope the shuttle doesn't do another one of those re-entry burn ups (OOOHHH too soon!?) and send the bio-matter flinging across a latitudinal line along south U S of A showering down on its unsuspecting inhabitants.
Or do we care? And would we be able to tell the difference if they do become infected with astro-zombification viruses?
Frickin southern redneck merkins. I saw that Top Gear special when they drove those cars across the deep south with 'Nascar Sucks' plastered all over one of their cars - they all ignant dawg.
I beg to differ, metal is not the optimum medium for heat transfer in regards to thermic transport properties, just the easiest to work with all things considered. granted, you can create a gradient to draw heat out with more reliable and constanr results, but over all speed and heat conductivity cannot be beaten by oil and polymers there of.
Maybe you mean metal is by far the most efficiant dissapator of heat? I think that was a very open comment, and probably not worth me thinking about it, but hey, it's wednesday, i'm bored.

You obviously never served time in one of our fine higher education establishments. If you had you would have known how the contents of your average student house fridge can mutate, over time, into the most hideously deformed and unidentifiable biological waste of the lowest order.
