24 fev 1969 ano - Mariner 6

Descrição:

U.S., launched Feb. 24, 1969 and successfully completed a Mars flyby on July 31, 1969. The spacecraft returned 75 photos.
Flying by over the equator and south polar regions and analyzing the Martian atmosphere and surface with remote sensors, as well as recording and relaying hundreds of pictures. By chance, both flew over cratered regions and missed both the giant northern volcanoes and the equatorial grand canyon that was discovered later. Their approach pictures did, however, show that the dark features on the surface long seen from Earth were not canals, as once interpreted in the 1800s.
