Viking 1: The Historic First Mars Landing in Pictures

Making History

Lockheed Martin

For over 50 years, NASA and other space agencies have been sending spacecraft to Mars. Today, a human mission to the Red Planet grows near. The foundational mission for expeditions to the Martian surface took place 40 years ago this week.

Putting the Pieces Together

Lockheed Martin

Construction of the Viking spacecraft was done primarily by the private company Martin Marietta (now Lockheed Martin). The team worked for six years to build the ground-breaking spacecraft.

Testing, Testing

Lockheed Martin

The Martin Marietta team developed fantastic new technologies just for the Viking mission, including innovative flight software and an X-ray fluorescence spectrometer instrument to test chemical compounds in the soil.

Packed and Ready

Preparatory Steps


Inside the Kennedy's Spacecraft Assembly and Encapsulation Facility-2 on Jan. 7, 1975, technicians ready the Viking Lander 1's aeroshell cover. This shell covered the lander during its 440,000,000-mile odyssey to Mars.

Inspecting the Protection


The aeroshell — made of a heat shield and containing parachutes and other entry components inside the "backshell" — protected the Viking Lander 1 during entry into the Martian atmosphere in July 1976.

Scrutinizing Connections

Awaiting the Mission

Beginning the Long Journey


Viking 1, atop a Titan/Centaur rocket, launched from Complex 41 at Cape Canaveral Air Force Station on August 20, 1975. The half-billion mile journey took 11 months. The spacecraft came into orbit around Mars in mid-1976.

Strange First Impressions


The Viking 1 Lander's first image of the Red Planet showed a few feet of Martian surface and the lander's own footpad. According to the team who oversaw the Viking program, this was intentional — in order to learn about the surface of Mars, the team wanted to see how the footpad would affect the soil.

Panorama of the Red Planet


Shortly after landing on Mars, on July 20, 1976, the Viking 1 Lander returned the first panoramic view of the Martian surface. The lander used the Scanning Camera 2 for a 300 degree image of Chryse Planitia, while the Sun shined in the west.
