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 from Cape Canaveral Air Force Station and reached the planet on November 14 of the same year becoming the first spacecraft to orbit another planet — only narrowly beating Soviet Mars 2 and Mars 3 which both arrived within a month.
