The two VIKING probes arrived in Mars orbit in 1976 when they started sending photographs back to Earth. The two orbiters continued sending photographs and the landers conducted experiments on the planet's surface until they failed as follows:Viking 2 Orbiter: July 1978 Viking 2 Lander: April 1980 Viking 1 Orbiter: August 1980 Viking 1 Lander: November 1982.
The Viking program sent two space probes to the planet Mars in 1976. It was a very expensive mission, costing approximately 1 billion dollars.
NASA's Viking 1 and Viking 2 landed on Mars in 1976.
First ever satellite to land on the planet Mars was a Russian probe called Mars 2. Albeit it did not land but crashed.

The Viking program was a pair of probes launched in 1975, Viking I and Viking II, which were both sent to land on Mars. They ran a series of experiments while on the planet, Viking I operated for just over 3 and a half years until it suffered battery failure. Viking II operated for just over six years, unfortunately human error caused its antenna to stop working, and it could no longer communicate.
