25 Years Ago: Vikings on Mars
On July 20, 1976, NASA's Viking 1 lander became the first U.S. spacecraft to land on Mars. It was followed weeks later by its twin robot explorer, the Viking 2 lander. Operating on the Martian surface into the early 1980s, the Vikings took thousands of pictures, conducted sophisticated chemical searches for life, and studied the Martian weather and geology. In the detailed image above, a field of rocks and boulders is viewed from the Viking 1 landing site on Chryse Planitia.
