November 21, 2008 (Computerworld) After the excitement of scraping up slivers of what turned out to be ice on Mars this summer, NASA announced late Thursday that it has discovered vast glaciers hidden under rubble.
One glacier is three times the size of the city of Los Angeles and up to a half-mile thick, according to an alert from NASA's Jet Propulsion Laboratory. The glaciers were spotted by the Mars Reconnaissance Orbiter, which in late September also sent back information about fractures in the surface of the Red Planet that once directed water flows through underground sandstone.
