Viking Lander 1 landed in Chryse Planitia, a planar area in the northern midlatitudes of Mars, on July 20, 1976. Cameras on the lander returned thousands of photographs of the blocky, undulating terrain around the landing site. The color of the surface and the sky is primarily due to the ubiquitous presence of fine, red dust. Parts of the spacecraft (a footpad on the right and the housing for the sampling arm on the left) are visible near the bottom of the slide. The horizon is approximately 3 kilometers (2 miles) away from the spacecraft.
