In a Reddit AMA, the billionaire laid further plans to get a million people living on Mars in the next few decades.
Mining will be a big part of the colony’s sustainability and Musk said the major trip would include droids to get the first digs done.
“Initially, glass panes with carbon fiber frames to build geodesic domes on the surface, plus a lot of miner/tunneling droids,” he said after being asked how the first structures would be built.
“With the latter, you can build out a huge amount of pressurised space for industrial operations and leave the glass domes for green living space.”
Studies done on meteorites proven to be from the red planet recovered magnesium, aluminium, titanium, iron, and chromium in amounts suggesting they were commonly found there.
Musk has said he wants SpaceX to begin flights to Mars in 2022.
