PHOTO CAPTION >

The Mars Global Surveyor Satellite carries an instrument known as the Mars Orbiter Laser Altimeter (MOLA) This device emphasizes terrain features, and the images it produces are false-colored to highlight detail. On the top globe, the Helles Impact Basin, a feature that is approximately 2,300 km in diameter,  is shown in dark blue. The lower globe prominently displays the Tharsis volcanic province and Valles Marineris. Go to the TVS website for color versions of both images.  (G. A. Neumann, MIT and NASA/Goddard, 1999)

TVS Presents

   Since ancient times, volcanism and volcanoes have frightened and fascinated humanity. Today this is equally true of the volcanoes on Mars, as we observe them with space probes. 

   This presentation introduces volcanism in general, and explores volcanism on Earth and on Mars. Ms. Froehlich will show us images of terrestrial volcanoes, and will show space craft photography illustrating characteristic examples from both Earth and Mars.
