At Work on Mars
Explanation:
To learn about the history of
Mars, just ask the rocks.
Last year, that's exactly what the robot rover
Sojourner did.
Sojouner can be seen, above, analyzing a rock nicknamed
Moe, trying to discern its past.
One significant
discovery of the
Mars Pathfinder mission was that of conglomerate rocks,
indicating the presence of running water in the past.
Such water, in turn, indicates that
Mars was much more like watery Earth in the distant past.
Visible in the foreground of
this color-enhanced mosaic is part of the
Sagan Memorial
Station, while a hill nicknamed one
of the "Twin Peaks" is
visible about a kilometer in the distance.
