Viking Lander Landing Sequence
This artist's representation shows the landing sequence of the Viking landers on the surface of Mars. Each Viking spacecraft consisted of an orbiter and a lander. The Viking 1 lander worked for more than 6 years after landing on July 20, 1976. Viking 2 landed two months later on the other side of Mars, where it transmitted data for over 3½ years.
