In 1961, the Soviet Union became the first to dispatch a spacecraft to study Venus. Although contact with Venera 1 was lost when it was some 7.5m km from Earth, the mission represented a partial success in that the ‘escape stage’ had set up a trajectory that took the probe within 100,000km of Venus that May, thereby demonstrating that interplanetary flybys were feasible. NASA’s Mariner 2 made a 35,000km flyby on 14 December 1962, during which a microwave radiometer established the temperature near the surface to be 480°C.
