Humans could have visited Mars or Venus in the 70s or 80s using variations of the Apollo spacecraft that went to the Moon. The catch was that they couldn't land. An Apollo-based interplanetary mission would have just flown by or possibly spent a few weeks in orbit, because landing would require a much heavier spacecraft and a lot more fuel. Because of this the spacecraft would have to be launched in several pieces and assembled in orbit, and demand the development of a lot of new technology and infrastructure (one of the original purposes for the International Space Station was as a kind of shipyard for interplanetary craft). As such, a Mars mission would be extremely expensive.
