Liquid water reservoir reported under Mars polar cap

[QUOTE="Fewmet, post: 6031111, member: 246836"] I do not know the details of what would reflect radar of the wavelengths they used, but to me "water-laden sediments" carries a connotation of much more water than hydrated minerals. I heard Kathryn Sturman (geophysicist with the University of Texas) on http://www.cbc.ca/player/play/1285450307799 (starting at 11:49) say it might be more like an aquifer. Sturman mentioned (and the [URL='https://physicsworld.com/a/liquid-water-discovered-beneath-mars-south-pole/']Physics World summary[/URL]) notes that the SHARAD data of the same region (which was higher frequency radar and would have penetrated as deep) failed to show water.
