The Surprising Ways Mars is Hostile to Life

Energy Source = Fusion reactor
Dust Storm = If Nomads on Earth can do it for thousands of years with no tech. we should have a solution for keeping solar panels clear and functioning e.g. powerful wind turbine to keep dust away
Magnetic Shield = Create local regional magnetic shield or literal shields and the hostile space between will be radioactive oceans to cross with well protected vehicles. Biodomes.
Thin air = create sealed plant terrarium with water vapor that become oxygen production units and carbon dioxide absorption units at our disposal. Biodomes.
