Excuse my ignorance.

I'm interested in what you said but am having trouble understanding.

ambient pressure in space? I was told space was a vacuum. I don't know a lot about it. It's cold but the sun bakes any matter at 260°, no atmosphere to protect and no wind to cool it off. im spit balling here. The module and the suits must be pressurized by a compressor er somthin.

Are they running compressors to compress the gass? Compressors take a lot of electricity. What am I missing?

it's cool. :) I understand your question. yes, space is a vacuum but it is pressurized within the suit or space capsule. So, basically, the gasses are carried in liquid form as they are more compact in that manner and easier for transport. in order to turn them into a gas, they will absorb large amount of heat as they expand. any fluid that expands will act like a heatsink as this process is performed. going from a high pressure liquid state to a medium suit pressure state and then finally to a low pressure open space state. at each stage this process will absorb heat voraciously. think of a large tank of liquid nitrogen held at a high pressure - even at sea level. if you allow the nitogen to evaporate / offgas, it will drop in temperature.

That was an Ayn Rand joke to you john galt.

Yes I get that, but where is all the electricity coming from to run the compressors?

for the lunar missions, there weren't any compressors in space. it was all compressed before being sent into space. it's an excellent engineering question, for sure.

Water is dense and will transfer heat much faster than air at sea level.

Vacuum of space won't heat/cool as fast. But I don't know much more about space stuff
