I really hope they take as many people as they can. Really.
And I hope they all take the most efficient path to Mars, rather than the fastest. And I hope they send them all in a very short time period, and Musk never bothers to read anything about the hazard of traveling in space outside of our magnetosphere.
Yeah what you said - fire him out of a cannon.
I really don't like to be the "well acktschually" guy but the major constraint for a mars settlement is the availability of water. mars is inhabitable (with the help of technology ofc) wherever there is water, probably it in the form of ice underground. Various research missions are currently mapping that out. Here's a map from around 2000:
Have you read A City On Mars? It has quite a detailed look at many of the challenges. You've pointed to some research relevant to the possible availability of water - which is great, but I think it would be better to say "a major constraint" rather than "the major constraint."
