Mars Orbiter Sees Changes

pin_gween writes "The long-lived Mars Global Surveyor (8 yrs and flying) has enabled scientists to see changes in the surface of Mars. From the article: 'New gullies that did not exist in mid-2002 have appeared on a Martian sand dune. New impact craters formed since the 1970s suggest changes to age-estimating models. And for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size, suggesting a climate change in progress.' The probe's primary mission ended in 2001 and scientists are hopeful the orbiter's life can be extended for another 5 -10 years."

    just think about the percentage increase in cars on Mars in the last few years!

    Cars? Have you see the size of those things? They're definitely SUVs! And who was president when they were sent there? George W Bush!
