Summary
NASA/JPL-Caltech released a commemorative poster, wallpapers and backgrounds on July 20 to mark 50 years since Viking 1 became the first spacecraft to land successfully on Mars.
July 20, 1976 launched that milestone: Viking 1 sent back the first images from the Martian surface, while Viking 2 followed on Sept. 3, 1976, with both missions paired with orbiters.
The two landers dug into Martian soil for early clues about the planet and possible life, far outlasting their planned 90-day missions—Viking 2 operated until 1980 and Viking 1 until 1982.
Nearly 2 dozen NASA Mars missions now trace back to Viking, and the anniversary materials frame that legacy as the foundation for current habitability research and future human exploration.
Fifty years after Viking's landing, did its experiments accidentally destroy the Martian life they were designed to find?
Viking showed us Mars' surface. What deadly secret does its dust now hold for the first human astronauts?
The Viking Missions 50 Years On: Unresolved Questions and Enduring Impact on Mars Exploration
Overview
On July 20, 1976, the Viking 1 lander made history by successfully touching down on Mars, with a confirmation signal reaching NASA's Jet Propulsion Laboratory 19 minutes later. This achievement, followed by Viking 2's landing, sparked celebrations and marked the start of an unprecedented era in Mars exploration. The mission team quickly shifted focus to the first images and data sent from the Red Planet, setting the stage for decades of discovery. The Viking missions not only advanced our understanding of Mars but also inspired ongoing scientific debate and future missions in the search for life beyond Earth.
