The "Dead Seas" of Mars Discovered?

Free episodes:

Water is a necessary but not a sufficient condition. There must be an energy source. Sunlight at the surface may be no good because of exposure to radiation, and extreme cold. Underground life might utilize internal planetary heat but a possible problem is exhaustion of the heat due to massive volcanism in the past. Lastly, even if there is sufficient water, heat and carbon for life, there may not be enough nitrogen, given inability of this gas to persist on Mars, where gravity is too weak to retain it over geologic time. Most of it appears to be gone.

You should contact NASA and let them know what to look for they probably don't realise.
