VIEW INSIDE MARS REVEALS RAPID COOLING AND BURIED CHANNELS

     Some of Mars' best kept secrets, long buried beneath 
the surface of the red planet, were recently revealed by 
instruments on NASA's Mars Global Surveyor spacecraft.  

     New observations of Mars reveal that the planet's flat 
northern lowlands were an early zone of high heat flow that 
later may have been the site of rapid water accumulation, 
according to a view of the Martian interior generated using 
data from Mars Global Surveyor (MGS).  Elevation and 
gravity measurements, which have been used to probe beneath 
the surface of Mars, indicate a period of rapid cooling 
early in Martian history, and evidence for large, buried 
channels that could have formed from the flow of enormous 
volumes of water.
