Water on Mars?! …
Well, anyone thinking of long-range manned space travel cares. Liquid water on other worlds, aside from indicating a possibility of life, is a necessity for deep space exploration in the long run. Further, it’s also a necessity for any kind of future extraterrestrial base establishment, be it purely research, mining, terraforming, or military.
I am in partial agreement with Bornagain – the Shroud and water on Mars research are not even in the same category; by comparison to finding liquid water on Mars, the Shroud of Turin is a tourist dollar store trinket.
