Dear Wiki Questioner, The first spacecraft that visited the planet Mars was the "Mariner 4". It was launched by NASA in 1964 and simply flew past Mars, taking pictures and gathering information as it passed! The first spacecraft to LAND ON Mars were the "Mars 2" and "Mars 3" probes launched by the USSR in 1971. Unfortunately, both of these probes stopped functioning not long after landing on Mars. NASA's "Viking 1" lander was the first spacecraft to land on Mars and function for an extended period of time (6 years in fact).
