Mars: Sunset at the Viking Lander 1 Site (1976) | NASA
Happy Viking 40th Anniversary! (1976-2016)
First Successful Mars Landing!
On July 20, 1976, at 8:12 a.m. EDT, NASA received the signal that the Viking Lander 1 successfully reached the Martian surface. This major milestone represented the first time the United States successfully landed a vehicle on the surface of Mars, collecting an overwhelming amount of data that would soon be used in future NASA missions.

First Successful Mars Landing: NASA Viking 40th Anniversary
(1976-2016) | July 20, 1976, 7 years to the day after the Apollo 11 moon landing, the first successful landing on Mars by NASA's Viking spacecraft took place. The ambitious Viking missions continue to evoke pride and enthusiasm for future space exploration. Built for 90 days, the Viking 1 lander sent data from Mars for over 6 years.

NASA's Viking 1 and 2 missions to Mars, each consisting of an orbiter and a lander, became the first space probes to obtain high resolution images of the Martian surface; characterize the structure and composition of the atmosphere and surface; and conduct on-the-spot biological tests for life on another planet.

Viking provided the first measurements of the atmosphere and surface of Mars. These measurements are still being analyzed and interpreted. The data suggested early Mars was very different from the present day planet. Viking performed the first successful entry, descent and landing on Mars. Derivations of a Viking-style thermal protection system and parachute have been used on many U.S. Mars lander missions since.
