On this day in 1971, Mariner 9 leaves for Mars:
Mariner 9 (Mariner Mars ’71 / Mariner-I) was an unmanned NASA space probe that contributed greatly to the exploration of Mars and was part of the Mariner program. Mariner 9 was launched toward Mars on May 30, 1971[1][2] from Cape Canaveral Air Force Station and reached the planet on November 14 of the same year,[1][2] becoming the first spacecraft to orbit another planet[3] — only narrowly beating the Soviets’ Mars 2 and Mars 3, which both arrived within a month. After months of dust storms it managed to send back clear pictures of the surface.
Mariner 9 returned 7329 images over the course of its mission, which concluded in October 1972.
