29. Dust Storm at Viking 1 Landing Site (22°N,48°W)
This image shows a rock called “Big Joe,” about 2 meters across, at the Viking 1 landing site. The views on different days (sols) show how atmospheric dust affects the brightness of the sky. There was a dust storm on sol 1742. The blue-green tint on some areas of Big Joe is a result of computer processing and is not true to color.
