Sorry to drag this off into a side-debate about the temperature of Echo Base, but it would have to be warmer inside Echo Base than -32 degrees (-60 at night). Celsius or Farenheit, that's too cold for people to live and work. That's about as cold as Antarctica.
It doesn't look warm and toasty inside Echo Base, probably -12 degrees Celsius. So my question is, at the threshold of the hangar door, would the -32 degree air meeting the -12 degree air produce any kind of visible water vapor, or is it too cold?
