Well, I'm certainly not complaining. I've very much enjoyed reading through this thread and sponging up all sorts of information. I just figured I'd go ahead and answer the OP's question. Don't let that stop the tangents. biggrin.gif

Space isn't a completely empty vacuum. Space has a temperature. Space is just So vast that it would be rather hard to fill so it acts as a vacuum. I bet you can (teraform) space if you were able to isolate and sustain an atmospheric bubble with no mass creating gravity. smile.gif

Most of the second half of the article discusses heat transfer using liquid cooling and large radiators. I can't believe all of the googler's haven't already just tried a search for "radiator in space", sixth hit down. The only hit from nasa.gov...... Hey, at least I learned something today. tongue.gif
Although I'm not entirely sure what any of this has to do with new tech heat sensors in heatshields primarily used for reentry. The problem isn't cooling it in outer space so much as it is cooling it while slamming through the Earth's atmosphere. The new tech at the start of the article could potentially dramatically (if not completely) decrease the energy consumption of the cooling required for the heatshield sensors. Fin.

I actually brought this up in post 11...and the point of this thread was supposed to be about lower massed heat shields, but the OP started it off on just using space cool components on a vehicle in space. I don't think they understood the article, but most news topics get derailed anyway. Why not start off with post 1.

Space could be absolute zero and it still would not be a good medium for cooling anything. Though a temp probe launched into space will always have a reading higher than absolute zero there will always be something around...even if it was trace radiation or a single dust particle. However, the space around earth is rather warm if you are in the sun...something like a 120°C if I remember right...and about -120° in the shade, but since things in space can only cool by radiation you could toss a hot potato out the air lock on the dark side of the moon and it would stay hot for decent amount of time...likely a few hours. Anything actively heating up, like electronics, will require massive cooling.

I knew very well that the article had nothing to do with my question hehe

But it just got me wondering about it - and I knew the best way to find out what to ask in here of all places

Also because I knew some interesting stuff would come from it ^^


and YES! I am the Master of Derailment!

i have a solution for dissipating heat into space. use compressed gas, release it at very low pressures into a set of thermal radiators on the outside of the ship. the expanding gasses would expend any heat it absorbs almost instantaneously due to dispersion. however you would need a lot of gas for any long trip.....

The mass effect games are the only big games i know of that puts heat as a concern in space......
post #37 of 51
space is a vacuum. they say what kills someone in space the quickest is the utter lack of pressure, so every bit of your body boils at once- down to each individual cell.

so two words: evaporation cooling.

Yes it is... Look at time travel, it's been proven that it can't be done. Time viewing however is a concieveable theory

Having a physcial object go faster than the speed of light, been proven that it can't be done. In addition to this, faster than light travel is possible if you use a bubble of energy to encompass a physical object to move it faster than light, which has been proven possible.

See, some things aren't possible biggrin.gif



However, on that note, this is all only proven by scientists of today using modern technologies and theories. For all you know a revolution in time travel theory could happen which could change the way it is looked at entirely (to cut it short they could just be looking at it entirely wrong, not an unplausible thought even for a scientist). Once upon a time people probably thought flying to the moon was impossible.

 

Never say never, regardless of the probability. One day we might just be surprised. Travelling forward in time is very much possible, we just have to refine the method (we already travel forward in time at a very slow rate, we just need to slow the aging process, or even remove it, and remove the element of waiting). It's travelling backward that seems the most unlikely.

 

Think of this. Scientists are already capable of teleportation at a very basic level (for a scientist anyway). Now imagine being able to teleport someone, hold them indefinitely in limbo, and release them out of teleportation at a specfic time and date in the future.

 

Not so impossible when you think about it like that. We just don't have the technology or the means to prove it's possible, yet. It's something that is likely hundreds or thousands of years ahead of our time, but I wouldn't rule out the possibility of it.

if this liquid and Enclosure doesnt Exist, whos to say we cant make one?

I would wager nothing is impossible, but why use a liquid? Liquids are costly and the manner in which containing and getting them into space is not cheap. I would image something more stable, perhaps a metal that can get rid of the heat much like a heatsink? Since the background temperature of space is near absolute zero, and considering the second law of thermodynamics (http://en.wikipedia.org/wiki/Entropy). I think with any space application it should be a matter of obtaining the most effecient materials and processes. However not to stifle innovation, what liquid and what kind of system would you propose for cooling?

The reason we are warm on earth is because the sun heats up the air, the air retains the heat and we stay warm. That in addition to the ozone etc etc.
Comps

Not to call you out, and since you are apparently an astrophysicist (seriously, and not to be mean, but this was a large part of my life for some time), here is more information stating that what you believe is simply wrong. Not to be rude, but now you are sincerely asking for this:
http://www.astro.ucla.edu/~wright/Eddington-T0.html
(Also here is another one that is a bit easier to read)
http://www.straightdope.com/columns/read/2172/whats-the-temperature-of-space

Also, if there is no temperature in the vaccum of space that would mean space would exist at absolute zero, this is the point where all atomic and quantum movement stops. period. If space had no temperature, then the universe as we know it would not work the way it does, (i.e Photons would stop in thier tracks beofre leaving the mass of thier star.) This can be debated of course (though I dont think you will make much headway), however you simply believing that you need 'atoms and molecules' to retain temperature is wrong beacause you forget about the huge swath of subatomic particles that can populate any point in space at any time. Cosmic background raditation is a large part of that temperature that exists in space. The comment of yours that i have bolded proves the point I am making. If the sun heats up the air on the planet (which I would believe no reasonable person would disagree with) then how does that heat get to the planet? There is obviously a transition period of where the particles traverse space in between the sun and the planet, hence the heating of the planet. I don't believe any sane person would argue that photons quantum tunnel to the planet and forget about any kind of motion laws that describe our universe.

I challenge you to prove me otherwise.

There is already a proof that time travel will never exist...if it ever will exist some one would have come back in time and erased the Nyan Cat video from existence.

...or maybe it will exist and there have been far more annoying things made and they've been disposed of. eek.gif
