But even so, it doesn't seem that it could be worse than exposure to space in LEO. While I wouldn't risk it with any other alternative, it seems likely that if need be, a human could withstand several seconds of exposure to such conditions. The things I'd be worried about would be lack of atmospheric pressure and oxygen, rather than temperature. Obviously, a human being could withstand 40 F temperatures for a long time, even clothed ordinarily. I got the impression the OP was asking whether it was physically possible to stand on the surface of Titan. IOW- Would it support a man's weight. I heard recently that the surface is thought to be spongy. It might be a good idea to have Teflon treads on your boots to avoid getting bogged down in sticky tar. Depending upon how much methane from the last rain was present in the soil, it should range from brittle sandy stuff to mushy sticky stuff. Another concern would be highly flamable leaks from the respirator. One probably couldn't just vent exhaled breath, the oxygen content would still be high enough to be dangerous in a methane rich atmosphere. Some kind of re-breather with good seals around the mask covering the nose and mouth. Clif |

Well, looks like we're almost there. Just a few more hundreds of years
and a good reason for having an outpost there, like a petrol station for those interstellar travellers... :-) |
