Viking 40th Anniversary Emblem

Author/Origin: William Keeter, DMI/NASARelevant Mission: Viking NASA's Viking Project found a place in history when it became the first U.S. mission to land a spacecraft successfully on the surface of Mars. Two identical spacecraft, each consisting of a lander and an orbiter, were built. Each orbiter-lander pair flew together and entered Mars orbit; the landers then separated and descended to the planet's surface. https://nasa3d.arc.nasa.gov/detail/viking-40emblem
