Most of what we know about Venus is derived from the intensive Soviet study of the planet. The only existing images from the surface were returned from four of their landing craft. Attempts to carry phototelevision cameras to Venus in 1962 and 1965 failed, but the Venera-9 orbiter performed the first long-term imaging survey of cloud circulation, in 1975.
