Throughout the Viking Mission which extended from July of 1976 through July of 1980, more than two Mars years, spectral and photometric observations were made using some complement of the four, paired camera systems, two on the surface and two in orbit. Results of these studies have enabled definition of the probable composition and texture of the surface, grossly and at high resolution; determination of optical properties of the atmosphere from two vantage points and under varying conditions; and overall, a better understanding of the Martian environment.
