While it is likely that future Venus missions will be robotic craft, at one point someone in NASA carried out an interesting contingency study on sending a manned craft to orbit Venus.

The file (Click here:Manned Venus Mission 1967) works on the assumption that either the NERVA project had been carried through to completion or that NASA had retained the capacity it was developing for Apollo.

While the author does not rule out the possibility of a landing on Venus, he notes that owing to the unknown surface conditions they would be highly unlikely.

Launch times are given as being between 1975-1986 and are designed to allow 40 days in orbit at Venus.

As someone who was growing up during the period mentioned I would like to say that such missions would have been far more interesting than what actually occurred.

It's going to take an awfully long time for a rock the size of Veus to cool enough to freeze CO2 I would imagine.

I remember reading (a long time ago) of another idea, that would have split the CO2 atmosphere into an O2 one with a lot (and I mean a lot) of carbon dust coving the surface, although quite how that helps matters I can't remember! blink.gif

But anyway, why get rid of the atmosphere when it provides such a nice habitat at 50km... smile.gif

Wow, "cities designed to float at about fifty kilometer altitude in the atmosphere of Venus"... ohmy.gif
This is an intriguing idea, it recall me the cloud city from "Empire Stikes Back"! rolleyes.gif

Saturn would be much more suitable for a floating city- you have plenty of raw material nearby (in the Saturnian moons) and gravity at reasonable atmospheric depths is still close to 1g.
