The Viking 2 mission was part of the American Viking program to Mars, and consisted of an orbiter and a lander essentially identical to that of the Viking 1 mission. [1] Viking 2 was operational on Mars for 1281 sols (1,316 days ; 3 years, 221 days ).
Viking 1 entered Mars orbit on June 19, 1976, with Viking 2 following on August 7. After orbiting Mars for more than a month and returning images used for landing site selection, the orbiters and landers detached; the landers then entered the Martian atmosphere and soft-landed at the sites that had been chosen.

Soviet Mars 3, which landed in 1971, was the first successful Mars landing, though the spacecraft failed after 110 seconds on the surface. All other Soviet Mars landing attempts failed. [2] Viking 1 and Viking 2 were first successful NASA landers, launched in 1975.
By Eric Sandler On August 20, 1975 -- 39 years ago today -- NASA launched the first of two spacecraft as a part of their new Viking program and the images they captured back in the '70s and '80s ...
Schematic of the Viking Lander Biological Experiment System. In 1976 two identical Viking program landers each carried four types of biological experiments to the surface of Mars. The first successful Mars landers, Viking 1 and Viking 2, then carried out experiments to look for biosignatures of microbial life on Mars. The landers each used a ...
Viking 1 was the first of two spacecraft, along with Viking 2, each consisting of an orbiter and a lander, sent to Mars as part of NASA's Viking program. [2] The lander touched down on Mars on July 20, 1976, the first successful Mars lander in history. Viking 1 operated on Mars for 2,307 days (over 6 1 ⁄ 4 years) or 2245 Martian solar days ...
The Viking program launched Viking 1 and Viking 2 spacecraft to Mars in 1975; The program consisted of two orbiters and two landers – these were the second and third spacecraft to successfully land on Mars. In 1976, Viking 1 and Viking 2 touched down on the Martian surface. These landers were significantly larger than the Soviet Mars 3 lander ...
