Mars - Viking 1 Lander

Sunset at the Viking 1 Lander site

Mars
Viking 1 Lander image of a martian sunset over Chryse Planitia. In this image the sun is 2 degrees below the local horizon. The banding in the sky is an artifact produced by the incremental brightness levels of the camera. This image was taken on the 30th martian day (sol) after touchdown, at 19:13 local time. The camera is pointing towards the southwest. (Viking 1 Lander, 12A240)
