Musk, Mars and Glass Domes (Earth Day)

Apr 22, 2020

If it wasn’t already clear that Elon Musk has considered virtually every aspect of what it would take to colonize Mars, it is now. As part of his Reddit AMA session, the SpaceX founder has revealed that his vision of a permanent colony would entail a huge number of “miner/tunneling droids.” The robots would build large volumes of underground pressurized space for industrial activity, leaving geodesic domes (made of carbon fiber and glass) for everyday living. As a resident, you might never see the ‘ugly’ side of settling the Red Planet.

Musk also explained how his colony would get to the point where it can reliably refuel spacecraft all by itself. Dragon capsules would serve as scouts, helping find the “best way” to extract water for fuel reactions. An unmanned Heart of Gold spaceship would then deliver the basics for a propellant plant, while the first crewed mission would finish that plant. After that, SpaceX would double the number of flights between each ideal Earth-Mars rendezvous (every 26 months) until the colony can reliably produce fuel by itself.

Although the main booster for interplanetary travel will “have an easier time of things,” Musk believes that the final iteration of Falcon 9 (Block 5) could be used “almost indefinitely” if properly maintained. Production on Block 5 should fly in the next 6 to 8 months.

Responding to a question about permanent habitation on Mars, Musk said that he envisions geodesic domes on the surface made with glass panes supported by carbon fiber frames. He added that ‘miner/tunneling droids’ will help ‘build out a huge amount of pressurized space for industrial operations’ underground.

Concerning transporting equipment, materials and people, Musk said that the first crewed mission would have about a dozen people, who will be tasked with building out and troubleshooting the propellant plant and Mars Base Alpha power system once it lands.

That’s all we’ve got for now: Musk noted that it’ll be a year or two before the company will release mockups of habitation environments. It’s kind of mind-blowing to think about such major issues and problems, and to observe a company already working to solve them for the future of mankind. However, this at least shows that Musk and team have thought about the minutiae of their plan — the big challenge is following through on all those promises.
