No Liquid Water on Mars

Researchers say that there is no evidence of limestone formations on Mars, meaning that there were never large quantities of liquid water flowing on the surface. This does not rule out ice or underground water says Philip Christensen of Arizona State University. He bases his conclusion on the information from Global Surveyor. Information that has no significant source of carbonates sources. Ross Irwin, a geologist with the Smithsonian Institution has pointed out, though, that basins and river beds, looking to be clearly carved by running water, allows for the possibility that any carbonate that was formed was carried beneath the surface of the planet, beyond the detection range of the TES.
