For many years, astronomers assumed that Venus, which on June 5/6 will cross the Sun’s disk as viewed from Earth, was Earth’s twin. The first successful planetary probe, Mariner II, revealed it to be hellishly hot. That put an end to thoughts of piloted Venus landings, but not to plans for piloted Venus exploration. Beyond Apollo blogger David S. F. Portree looks at one such plan — a Venus orbiter — that was meant as a stepping stone to Mars.
