Weird Geological Features Spied On Mars 99
astroengine writes "The High-Resolution Imaging Science Experiment (HiRISE) camera carried by NASA's Mars Reconnaissance Orbiter has spotted a strange geological feature that, for now, defies an obvious explanation. Found at the southern edge of Acidalia Planitia, small pits with raised edges appear to hug a long ridge. So far, mission scientists have ruled out impact craters and wind as formation processes, but have pegged the most likely cause to be glacial in nature."

No tectonics. The planet's core is supposed to be frozen, because it it so much smaller than Earth.

Archive.org to the rescue. Maybe the 9-June-2003 issue of Marsbugs (#23), page 5, "Martian Spiders"?: http://web.archive.org/web/20080725114636/http://www.lyon.edu/projects/marsbugs/volume10old.html [archive.org]
Man, just realized how long ago Spirit and Opportunity were.
