+ - SPAM: Mars' water too salty to support life

Submitted by

FiReaNGeL writes "A new analysis of the Martian rock that gave hints of water on the Red Planet now suggests the water was more likely a thick brine, far too salty to support life as we know it. "Liquid water is required by all species on Earth and we've assumed that water is the very least that would be necessary for life on Mars," says Nicholas J. Tosca, a postdoctoral researcher in Harvard's Department of Organismic and Evolutionary Biology. "However, to really assess Mars' habitability we need to consider the properties of its water. Not all of Earth's waters are able to support life, and the limits of terrestrial life are sharply defined by water's temperature, acidity, and salinity.""

Some people have a great ambition: to build something that will last, at least until they've finished building it.
