I don’t think they found water on mars. The ‘lab’ doesn’t support the observation that ‘some light colored particles vanished’. They also could have changed color after exposure to elements in the atmosphere.
Besides, even if they do find a few particles of water, it easily could have got there from a comet impacting the planet.
Certainly not anything to begin building a base on mars, what ever purpose that would serve since it’s basically uninhabitable even of there were rivers of water. A waste of money as far as I’m concerned.
Well that depends on if there really *is* a large anout of water there. Perhaps if there were, converters could be set up, and Mars could be Terraformed over a couple of hundred years...Or more...Ever read ‘Dune’?
