SUMMARY: A year's worth of observations from the Mars Odyssey spacecraft is starting to overturn some older theories about how environmentally active the Red Planet is. Using Odyssey's Thermal Emission Imaging System (THEMIS), scientists were able to detect geological formations of lava and rock which were deposited under varying environmental condition. One example is kilometre wide sheets of bedrock which are being scoured bare by wind. If Mars were less active, they should be covered in sand and dust.
