Viking: The Tenth Anniversary On the Cover: Ten years ago Viking 1 reached Mars, and the doughty little spacecraft began to turn the mysterious Red Planet into a familiar place to scientists and television viewers back on Earth. Here, the spacecraft looks across the cratered surface to the cloud-streaked horizon. Argyre Planitia, the large, smooth basin in the lower left, is probably the remnant of an asteroid impact.
