This video is mesmerizing to me and would have been anytime in my life, and, as someone from Texas who was ground zero for record setting sub-zero conditions last week it takes on additional significance for me. Most of my ranch is a wildlife refuge and because of remoteness I have my own solar farm, backup generators, propane tanks, deep water well and well stocked food supplies. An ecosystem on this planet is not easy. I spent the week helping others hauling wood, water, food and people to shelter. All of our Mars landers have faced much more inhospitable conditions but too your comment Mars is not wildly unfamiliar or unrecognizable. It’s eerily familiar to the way West Texas looks. We can build a diverse, redundant interplanetary backup there. Sitting aside climate change or any controversial models about this planet we are subject to possible massive disruption — be it asteroid, solar storm, biological catastrophe, magnetic shift or other. Let’s at least get on with exploring, it’s the best path to finding innovative solutions here and interplanetary for our whole species and the gains science has made so far.
