The temperature is so cold that it would freeze your body if you were exposed, so you would still need an airtight seal. But the atmospheric pressure is high enough that you wouldn't need a bulky vacuum-proof pressurized spacesuit.
- JoeAltmaier 10y agoI'm thinking if the surface temperature were hundreds of degrees below, and the air were thick enough for conduction, that the suit would have to be a vacuum-insulation type of thing anyway?
- LeifCarrotson 10y agoNo. Ambient-pressure-airtight is much easier than vacuum-airtight. A drysuit for scuba diving is ambient-pressure airtight, basically just a neoprene coverall with sealed seams. It's easy to move around in. But take away the external pressure, and you're in the middle of a 15 psi balloon,w which wants to be a sphere, not human-shaped. It becomes difficult to bend your limbs and fingers. Rotating a shoulder, neck, or wrist causes the suit to twist in like a party balloon. Anywhere the cross-section is not circular, it wants to be more circular. You either need a hard shell suit, a tolerance for this difficulty, or a lot of engineering.
- JoeAltmaier 10y agoCome on. Ambient-pressure-200K-differential-airtight is nothing like a scuba suit.
