First Viking mission to Mars: Aug. 1976
By discovering many geological forms that are typically formed from large amounts of water, the images from the orbiters caused a revolution in our ideas about water on Mars. Huge river valleys were found in many areas. They showed that floods of water broke through dams, carved deep valleys, eroded grooves into bedrock, and traveled thousands of kilometers. Large areas in the southern hemisphere contained branched stream networks, suggesting that rain once fell. The flanks of some volcanoes are believed to have been exposed to rainfall because they resemble those caused on Hawaiian volcanoes. Many craters look as if the impactor fell into mud. When they were formed, ice in the soil may have melted, turned the ground into mud, then flowed across the surface. Normally, material from an impact goes up, then down. It does not flow across the surface, going around obstacles, as it does on some Martian craters. Regions, called "Chaotic Terrain," seemed to have quickly lost great volumes of water, causing large channels to be formed. The amount of water involved was estimated to ten thousand times the flow of the Mississippi River. Underground volcanism may have melted frozen ice; the water then flowed away and the ground collapsed to leave chaotic terrain.

yes
The United States launched the Viking space probes. Viking 1 was launched on August 20, 1975, and Viking 2 was launched on September 9, 1975. These probes were part of NASA's Viking program to study Mars.
The Viking 1 and Viking 2 missions consisted of both an orbiter and a lander. The landers successfully touched down on the surface of Mars, while the orbiters remained in Mars' orbit to relay communications and data between the landers and Earth.
NASA's Viking 1 and Viking 2 landed on Mars in 1976.

Viking Lander 1 and Viking Lander 2 Yes, but there are more than that.
Viking 1 was launched on August 20, 1975, and the second craft, Viking 2, was launched on September 9, 1975. Viking 1 entered Mars orbit on June 19, 1976. The Viking 1 touched down on the surface of Mars on July 20, 1976, and was joined by the Viking 2 on September 3.
The Viking 1 and Viking 2 missions consisted of both an orbiter and a lander. The landers successfully touched down on the surface of Mars, while the orbiters remained in Mars' orbit to relay communications and data between the landers and Earth.
