Summary:

-- News Release: Magnetic Stripes Preserve Record of Ancient Mars 

*****
Magnetic Stripes Preserve Record of Ancient Mars
     NASA's Mars Global Surveyor has discovered surprising evidence of 
past movement of the Martian crust, further evidence that ancient Mars 
was a more dynamic, Earth-like planet than it is today. Scientists using 
the spacecraft's magnetometer have discovered banded patterns of 
magnetic fields on the Martian surface. If the bands on Mars are an 
imprint of crustal spreading, they are a relic of an early era of plate 
tectonics on Mars, according to a NASA scientist.
