    temperature regulation

    Vakuum has no temperature. Maybe a problem close to a star. And that bit against infrared loss…

    You know we have a space station up there?

      What…? Space is incredibly cold unless you have the warmth of a sun to warm you up, so you would always need heat, or AC at any given time. You can shut turn these lower to save power and find and optimal orbit for heat or something, but yeah, temperature regulation in space is crucial.

        Space has no air to transmit temperature. Well, maybe a few atoms of hydrogen and dust every m³ (and they do have about -200°C if i remember right), depending on where you are, but that does nothing. Only way to transmit heath in space is via radiation. You lose a bit of warmth via infrared radiation but i doubt that a crewed spaceship has no insulation. And the 400k liter of air in Enterprise should be an adequate buffer.

        That bit about inszantly freezing in space is Hollywood, same with firey explosions.

          You don’t instantly freeze, but you will freeze since space is incredibly cold, regardless of no atmosphere to transmit temperature. It’s still cold and you need heat to survive in any situation unless you are close enough for radiation from the sun.

          That bit about inszantly freezing in space is Hollywood, same with firey explosions.

          Radiational transfer is still a thing even though conduction transfer can’t happen.

          Why do you think you need to heat AND cool something depending on where you are in space? And if space couldn’t transfer temperature the sun could never warm us, there is obviously more than one way to transfer heat here……

          No one said anything about INSTANTLY feeezing. Try not to be so smarmy while completely missing the point.
