Mechanics of space suits?

Question

I do believe in the moon landing and was curious about the mechanics behind it. The moon has amazing temparatures that I doubt anyone could withstand unprotected. What kind of powers do these suits hold and have they evolved since the first moon landing?

I was thinking that myself. Was it kept at room temp?

Answer 1

internal a/c

Answer 2

The Moon's SURFACE has amazing temperatures. Please be clear about this. The Moon is in a vacuum. There is no such thing as ambient temperature up there. It is not the same as walking around on a hot or cold day on Earth, because when you describe the day as hot or cold you are referring to air temperature.

The extremes of temperature of the lunar surface result from the lunar day consisting of two weeks of uninterrupted sunlight and two weeks of uniterrupted darkness. There is not an instantaneous change from the highest to the lowest temperature.

As far as a man on the surface is concerned, he has two problems. One, the temperature of the surface itself, and two the incoming heat from the sun. The surface temperature is easily solved by making the soles of the boots thermally non-conductive. The other is solved by making the suit bright white so it reflects most incoming solar light and heat. The white of the suit was not an aesthetic choice but a practical one. Consider the difference between being in sunlight and shade here on Earth, or the way people who live in the desert keep themselves covered from head to toe rather than walking around with minimal clothing. They stay cool by effectively keeping their bodies permanently in the shade generated by their clothes.

The space suit's bigger problem was actually getting rid of the heat from the astronaut inside it. Once you've made the suit airtight, strong enough to resist puncture, and thermally protected from the outside, you then have the problem that the guy inside will overheat because of his own body temperature. To deal with that a system of tubes was sewn through an undergarment, and water was pumped through the tubes to a heat exchanger in the backpack. The water carried away some heat from the astronaut and kept the inside of the suit cool.
