Mars - Viking 1 Lander

Rocks and Silt in Chryse Planitia on Mars

Mars
This image of Chryse Planitia was taken by camera 2 on the Viking 1 Lander on 20 July 1978, exactly two Earth years after Viking 1 landed and took the first picture of this region. It shows a field of rocks and silt, some of the dust is concentrated into drifts, which may be stable erosional remnants of sedimentary cover. The darker drift at upper right appears to be enriched in ferrous material. The larger boulders near the horizon are about 90 meters away and 1 to 2 meters in diameter. Images were taken of the same scenes over a long period of time to look for surface changes. The camera is looking roughly south-southeast. (Viking 1 Lander, P-20453)
