A Human-Directed Bolide Impact-Dug Mars Funnel City

So far most publicly merchandized macro-engineering plans specifically designed to terraform Mars are impossible of achievement because Mars naturally lacks adequate physical resources allowing completion of that transformative anthropogenic event-process. These undoable plans fall mainly into two classifications: (I) artificial build-up Mars’ natural gaseous shell and (II) using capacious buildings to create a pressurized carapace civilization. In other words, to-date, all Mars terraformers are really thinking only as Earth counterfeiters who cannot ever gift humankind with a totally made-over Mars suitable for long-term settlement by humans. We suppose another, feasible, non-terraforming macro-project plan option, the rapid excavation of a single deep pit by successive timely big bolide bombardment. Such impacts cause anthropogenic erosion with some material leaving Mars forever. Funnel City, the subsequent deep pit will gravitationally attract most of Mars’ enshrouding ambient gases. The concentrated and densified gases within the deep hole might result in many Earthlings inhabiting safely a permanent exploration and exploitation Mars Base, the Funnel City. In effect, after the completion of this suggested macro-project, the extra-pit territory of Mars then may still closely resemble the present-day rocky and dusty surface of our Earth’s biggest natural satellite, the Moon. Funnel City can become the “dockyard” for Jack Smith’s Mars-centered Dyson Swarm used to send extraterrestrial power to Earth’s populace.
