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 not THAT difficult to shield solar cosmic rays. They're relatively low energy. You do need pounds of mass <perferably low atomic weight mass> per square inch surrounding you (sea level on earth has 14 pounds of mass per square inch over it)
What's a real problem is high atomic weight high energy galactic cosmic rays. But 14 lb/sq-in stops most of them, and shatters most into smaller and lower energy particles (cosmic-ray showers, they call'm) The problem is the simple one of having to live inside a radiation shelter most of the mission. And you have to take that mass with you whereever you go. |
