Mars as Habitat

Long before the advent of the Space Age, we have had enthusiasts poring over photos trying to find evidence of alien life on Mars.  The above photo is inspiring another wave of this effort.  It is always unconvincing as distant photos with lousy resolution always must be.

Yet is time to weigh in.  Provided we are prepared to accept the existence of heavy alien traffic in Terran airspace, I have shown that the only plausible reason for the actual level of activity is that large underground habitats already exist on Earth housing millions.

Accepting my conjecture that modern humanity first arose around forty thousand years ago and ultimately left Earth in order to shift the Crust in order to end the Northern Ice Age, it is no stretch to suppose they then built underground habitats afterward on Earth.

If all that was possible, then the next obvious thing is to establish a presence on Mars and to do it the one way that works.  That is to go underground

Mars is geologically stable and it should be possible in the lesser gravity to build rather large open spaces and create multi level structures in such spaces.    It should be much easier to build out than the equivalent in terms of outright space habitats using my hub and suspension system.  You do forgo the option of attaining a full g of gravitational acceleration on Mars, which may be undesirable.

Thus evacuating billions of space adapted humanity may well have been easier done by establishing underground complexes on Mars as a natural first step.

Since all the necessary elements will exist on Mars and sufficient water from the little we know to date, the construction process would have faced little in the way of bottlenecks.  Also, and not least important, atmospheric pressure would act as a fail safe in the event of accidents and generally prevent the loss off built up air reserves.

With internal fusion energy, heat and lighting to support growing would also be straight forward.  It is curious that the ideal metal for energy production turns out to be nickel which is the major constituent of metallic meteors and that the main waste is heat.  Thus even the recently announced Rossi Focardi Reactor is our key to Mars.

I really do not expect to find monuments on Mars in the open atmosphere.  It really comes to be a question of why?  However, perhaps it is time to look for underground structures on Earth.  Rock strength and dynamics and temperature pretty well limit us to shallow depths of less than ten thousand feet and likely less than two thousand feet to avoid hydrostatic pressure.

It is possible to engineer around such problems, but why bother?  On top of that it is necessary to engineer access points that generally open deep enough underwater to avoid accidental visits.  So all this means selecting regions a rock with good natural drainage to take advantage of yet close by a deep enough lake or the ocean.
