In the ariticle of "The Challenge of Exploring Venus", it say " solar power would be plentiful, and radiation would not exceed Earth levels. Not easy conditions, but survivable for humans." from this phrase, you can tell that scientists are really pensive about exploring Venus. Even though it is a difficult condition, they are willing to explore it, at least it is survivable for human.
