Mars, Rovers
and Water

In the 1970s the Viking spacecraft uncovered evidence that liquid water had flowed across the surface of the red planet.  More recent missions have discovered more compelling evidence for the presence of liquid water even though liquid water is not stable under current Martian pressure and temperature regimes.  Recently the extremely capable rovers Spirit and Opportunity have at last provided clinching evidence for the existence of a wet Martian past.  Images of the red planetís surface and instrumental evidence will be reviewed.

Please join us for light refreshments at 4:15pm outside WSC 109.
