Twin Peaks - Sol 10 (True Colors; credits: NASA/JPL)

Caption NASA:"The True Colors of Mars based upon three filters with the sky set to aluminance of 60. The color of the Pathfinder Landing Site is yellowish brown with only subtle variations. These colors are identical to the measured colors of the Viking Landing Sites reported by Huck et al. [1977]. This image was taken near local noon (12:00 M.L.T.) on Sol 10. A description of the techniques used to generate this color image from IMP data can be found in Maki et al., 1999".
