>>2322828Fun fact: Human skin is reasonably airtight. Surviving in a vacuum boils down to three issues:
1. providing oxygen
2. providing counter-pressure to your body's own pressure
3. keeping orifices sealed
So some skintight suit providing strong tension over the entire body and either a breathing mask or a blood-gas-exchanger would be sufficient to survive up there for a while. Direct, unfiltered sunlight could be an additional problem, but that's not much worse than standing in a desert under the sun at noon.
Or, much easier, they're robots.
