Agree or Disagree? It sounds strange that NASA is excited about finding a patch of wet sand in a desert on Planet Mars. When here on?

That's true, but the boiling point of water also depends upon temperature and what is dissolved in it. If the ambient temperature is somewhat below zero Celsius, and the water contains sufficient quantities of toxic dissolved salts in it, then the water may not boil even at the low pressures found on Mars. Also if a liquid is seeping below the surface, the overburden of dust may also increase the pressure sufficiently to stop the liquid from boiling for awhile.

Note that the pressure at the surface of Mars also depends upon the altitude of the landscape. In deep craters and in other low lying areas, the pressure will be considerably higher than on higher ground. Hence we would expect traces of highly toxic salt-laden water to seep through the ground in low lying areas of Mars at certain times of the year.

The recent discovery of hydrated rocks on or near the surface of Mars in a few very small places confirms that indeed there may be seeping poisons just below the surface. Cheers!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
