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.
Viking 2 landed on Mars on the September 3, 1976
The viking 1 landed on Mars in July 20th 1976.
Viking 1 landed on Mars on the 19th of June, in 1976.

Viking 1 landed on Mars in July 1976.
The first spacecraft to land successfully on Mars was Viking 1 in 1975
First ever satellite to land on the planet Mars was a Russian probe called Mars 2. Albeit it did not land but crashed. The first successful probe to land on Mars was Mars 3 sent by the Russians, however the probe was operational for 15 minutes after landing on Mars. The first American probe to land on Mars was the Viking 1 on the 20th of July 1976.

The NASA Viking 1 and 2 probes were targeted to two specific regions on Mars.- Viking 1 landed on July 20, 1976 on the "Golden Plain" (Chryse Planitia) about 22° north of the Martian equator.- Viking 2 landed on September 3, 1976 on the "Utopia Planitia" plain in the northern mid-latitudes, on the opposite side of Mars from Viking 1.
The first United States spacecraft to land on Mars was Viking 1 on June 19, 1976. It was followed by Viking 2 on September 3, 1976.
The first man made probes to successfully land on the surface of Mars were two Soviet probes; Mars 2 on November 27 and Mars 3 on December 2, 1971, but both ceased communicating within seconds of landing. The NASA Viking program had two landers; Viking 1 remained operational for six years, Viking 2 for three years after their 1976 landing.
