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.
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.

The first NASA rover, Sojourner (on the Mars Pathfinder lander), and twin rovers Spirit and Opportunity, used a combination of parachutes, retrorockets, and airbags for landing. Curiosity, launched in 2011, weighs nearly 900 kg, and was too heavy to be landed this way, as the airbags needed for it would be too heavy to be launched on a rocket. [2]
The Mars 1M programs (sometimes dubbed Marsnik in Western media) was the first Soviet uncrewed spacecraft interplanetary exploration program, which consisted of two flyby probes launched towards Mars in October 1960, Mars 1960A and Mars 1960B (also known as Korabl 4 and Korabl 5 respectively). After launch, the third stage pumps on both ...
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 ...
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 robotic arm to pick up and place soil samples into sealed test ...
