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.
The Viking 1 lander touched down on the surface of Mars on July 20, 1976, more than two weeks before Viking 2 ' s arrival in orbit. Viking 2 then successfully soft-landed on September 3. The orbiters continued imaging and performing other scientific operations from orbit while the landers deployed instruments on the surface.
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). The Viking 2 lander operated on the surface for 1,316 days, or 1281 sols, and was turned off on ...

NASA's Viking 1 and Viking 2 space probes arrive at Mars. Each Viking mission consists of an orbiter, which photographs the planet from above, and a lander, which touches down on the surface, analyzes the rocks, and searches unsuccessfully for life.
Vikings 1 and 2, launched in 1949 from White Sands Missile Range in New Mexico, both suffered from premature engine cutoff due to turbine leaks, significantly reducing their maximum altitude. [ 6 ] : 98–102 The improved Viking 3, launched on 9 February 1950, reached 50 mi (80 km) and could have gone higher.
Viking 2 was powered by a nuclear cell whereas Spirit is powered by solar arrays. Until Opportunity overtook it on May 19, 2010, the Mars probe with longest operational period was Viking 1 that lasted for 2245 Sols on the surface of Mars. On March 22, 2010, Spirit sent its last communication, thus falling just over a month short of surpassing ...
