Mariner 6 and Mariner 7 (Mariner Mars 69A and Mariner Mars 69B) were two unmanned NASA space probes that completed the first dual mission to Mars in 1969 as part of NASA’s wider Mariner program. Mariner 6 was launched from Launch Complex 36B at Cape Canaveral Air Force Station[3] and Mariner 7 from Launch Complex 36A at Cape Kennedy.[2] The craft[clarification needed] flew over the equator and south polar regions, analyzing the atmosphere and the surface with remote sensors, and recording and relaying hundreds of pictures. The mission’s goals were to study the surface and atmosphere of Mars during close flybys, in order to establish the basis for future investigations, particularly those relevant to the search for extraterrestrial life, and to demonstrate and develop technologies required for future Mars missions. Mariner 6 also had the objective of providing experience and data which would be useful in programming the Mariner 7 encounter five days later.
