While it has been known that Mars’s north pole contains an abundance of water, it looks as if some French scientists have discovered that water ice located up north may be much purer than we have originally thought.
(Physorg.com) Radar data sent back by the US Mars Reconnaissance Orbiter (MRO) point to 95 percent purity in this deposit, France’s National Institute of Sciences of the Universe (Insu) said in a press release.
The Martian polar regions are believed to hold the equivalent of two to three million cubic kilometres” (0.47-0.72 million cu. miles) of ice, it said.
Although its fairly obvious that the Martian water would still have to be heavily filtered, this high concentration of water ice does give the red planet some much needed real estate value.
