Apparently lifeless surface of Mars

Apparently lifeless surface of Mars

Fig. 8.29 . The Martian surface in western Chryse Planitia, as viewed from the Viking 1 lander on 3 August 1976. Wind-blown dust clings against the eroded rocks, creates dust drifts and fills the sky. These drifts were little changed during the six years they were observed from Viking 1, and revealed no evidence for the movements of any living things. Mars is instead a cold and desolate world in which the silence is broken by the roar of winds, the hiss of dust, the rumble of mammoth landslides, and perhaps by outbursts of active volcanoes.
