Well written, Will. Humans have evolved to live comfortably on 10% of this planet -- 10% is too hot, 10% too cold, 70% is briny water. Colonizing a planet that is orders of magnitude more hostile (and immensely expensive to reach) will remain a pipe dream for the foreseeably future. Incidentally, did you know that if Endeavour finds life on Mars -- even some ancient fossils, then we are doomed! https://frederic-38110.medium.com/if-we-find-life-on-mars-we-are-doomed-6b9a0577990c
