We Are The Martians

On the Cover: Viking Lander 2 views Utopia Planitia on Mars. Spacecraft surfaces in the foreground include color targets for calibrating the transmitted images, as well as a micro-print frame bearing about ten thousand names of people involved in the project. Viking Lander 1, on the other side of the planet in Chryse Planitia, continues operations and has been named the Thomas A. Mutch Memorial Station in memory of the leader of the Viking imaging team. A commemorative plaque will be installed by the next Earth-launched expedition to visit the Lander.
