Image of Venusian surface taken by Venera 9

Venera 9, launched June 8, 1975, touched down on Venus and transmitted the first images ever from the surface of another planet.  The lander detached from the orbiter on October 20 and made a soft landing 2 days later near Beta Regio.  It transmitted for 53 minutes before falling silent. It detected hydrochloric acid, hydrofluoric acid, bromine and iodine.  Venera 9 measured a surface pressure 90 times that of earth and a sultry atmosphere of 485° C.
