I always assumed their big ship is for putting weapons in space. Are they actually funded for building colonies on Mars? What percentage of the population are resilient, physically fit, highly intelligent and mentally stable enough to endure such a harsh environment? AFAIK most of the experiments in bio-domes located in deserts simulating Mars on earth had failed miserably.
