Martian water suitable for life

Martian water suitable for lifeWater on Mars has been found to be suitable for life. The mineral evidence in the Martian water is capable of supporting life.

NASA's Mars Reconnaissance Orbiter has finally spotted rocks on Mars which contain carbonate minerals. The scientists disclosed in a meeting of the American Geophysical Union in San Francisco that deposits of carbonate, formed in neutral or alkaline water, were spotted by NASA's Mars Reconnaissance Orbiter. The landscape viewed by Mars Reconnaissance Orbiter (MRO) is believed to have originated more than 3.6 billion years ago.

"Obviously this is very exciting," said John Mustard of Brown University in Rhode Island. "It's white -- it's a bulbous, crusty material."

The presence of carbonate minerals was detected in a mid-latitude region called the Nili Fossae, on the western edge of the Isidis impact basin. The size of the deposits is nearly that of football fields.

Carbonate is formed by the mixture of water and carbon dioxide with calcium, iron or magnesium. Since carbonate dissolves quickly in acid, so the present discovery counters the theory that all water on Mars was at one time acidic.
