- Air cooling is also relied on, at least on the Shuttle: There is a
- 10-psi mode, used during EVA missions to reduce pre-breathing
- requirements. Rockwell, however, was sufficiently concerned about
- cooling at low cabin pressure, to have a clause written into the
- contract: Rockwell has no responisbility what so ever for any electronics
- failures related to low cabin pressure...

- Actually, Vail or Aspen at ~10 psi average, would be a better example
- than Denver (~12 psi...) I have never understood why NASA doesn't
- consider this fact relevant. I know the reason the Case for Mars IV
- conference endorsed 14.5psi for Mars missions: NASA apparently likes
- it and will probably be using that pressure in many existing systems
- by the time a Mars mission is launched. Having two different pressures
- is a _major_ pain, so the general consensus was to stick to 14.5psi...
