THE VIEW FROM THE SURFACE
The colors in this slide have been computer enhanced in order to show the details of the martian surface. As a result, the colors shown here do not precisely represent those that a human observer would see on Mars.

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.
