...Mars Science Lab Rover... entry, descent and landing video
This is a great animation, science fiction becomes fact! And less than two years to launch! http://mars.jpl.nasa.gov/msl/gallery/videos.html And an almost crater-less (young) landing site full of hydrated clays with evidence of an ancient lake. http://hirise.lpl.arizona.edu/PSP_002828_1700 Hydrated clay! "The clay minerals are especially promising in the search for ancient life on Mars," UA Professor Alfred S. McEwen, principal investigator for the high resolution camera, said." http://www.jpl.nasa.gov/news/news.cfm?release=2007-116 Mars has plenty of underground water/ice, and it's orbit means ice ages should wax and wane somewhat as on earth. Even with the thin atmosphere, underground water melting out could replenish ice capped lakes faster than the ice would ablate away. There's no reason to assume Mars has been dry everywhere for geologic time as has been assumed. Odyssey Studies Changing Weather And Climate On Mars "One explanation could be that Mars is just coming out of an ice age," Feldman said. "In some low-latitude areas, the ice has already dissipated. In others, that process is slower and hasn't reached an equilibrium yet." http://marsprogram.jpl.nasa.gov/odys...20031208a.html Compare the delicate erosion pattern seen in the ...shadows...cast in both pics below. And the same gravely surface. How long ago was water there???
