Mariner 6, spacecraft to Mars, launched 1969

Mariner 6, one of two probes to explore Mars, launched February 25, 1969.  Mariner 7 launched the following month.  Mariner 6 made its closest approach to Mars on July 31, 1969, less than a week after Apollo 11's mission.  As a consequence, Mariner 6's achievements did not receive the attention it should have.
