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 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.

Astronomers reflect on the 25th anniversary of the Mars rover landing, the first wheeled robot to roam a planet. It's been 25 years since the landing of the Mars Pathfinder. Planetary exploration ...
In 1976 two American Viking probes entered orbit about Mars and each released a lander module that made a successful soft landing on the planet's surface. They subsequently had the first successful transmission of large volumes of data, including the first color pictures and extensive scientific information.
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 ...
