The first probe to Venus was launched by Russia in 1959, only two years after they had launched the first space satellite, Sputnik. After many not very successful attempts, Venera 3 landed a capsule on the surface in 1965, but communication ceased immediately. Venera 4 in 1967, also landed a capsule by parachute through the atmosphere, which transmitted for a short time, but did not survive on the surface which has a temperature hot enough to melt lead and an atmospheric pressure 90 times that on Earth.
