An interesting bit of Soviet history. They successfully landed 10 probes on the surface of Venus between 1967 and 1984 and broke a lot of barriers in space exploration. Among the other results, probes of the series became the first man-made devices to enter the atmosphere of another planet (Venera 4 on October 18, 1967), to make a soft landing on another planet (Venera 7 on December 15, 1970), to return images from the planetary surface (Venera 9 on June 8, 1975), and to perform high-resolution radar mapping studies of Venus (Venera 15 on June 2, 1983). The entire series could be considered highly successful. The surface conditions on Venus are extreme, therefore the probes only survived on the surface for a duration of 23 minutes (initial probes) up to about two hours (final probes). en.wikipedia.org/wiki/Venera
