Venera 3 launched to Venus 1965

Venera 3, launched November 16, 1965 by the Soviet Union to Venus, is the first spacecraft to (crash)land on another planet.  Venera 3's communications system failed about 17 days before it reached Venus.  It is believed to have entered the Venusian atmosphere March 1, 1966.

Thirty-one years to the day later, the Russians launched Mars 8, November 16, 1996 to Mars, but the spacecraft failed and re-entered Earth's atmosphere.  So instead of landing on Mars, it crashlanded on Chile, Bolivia and in the Pacific Ocean.
