After the arrival of the new colonists, the construction of the Mars Colony also entered the second stage.
Celestial Trade had a clear position of the Mars Colony as the solar system industrial base from the beginning, so the development direction of the second stage of the colony had been quite clear. The focus was mining, mining, and steelmaking!
Steel was the foundation of industry. To produce on Mars, steel production must keep up.
It wasn't difficult to achieve this on Mars. It was possible to smell rust when one bent down and grabbed a handful of sand. It was just a matter of the amount that was the concern. Also, the development of heavy industry had the added benefit of artificially causing a greenhouse effect that would indirectly change Mar's atmospheric thickness. Perhaps after a few centuries, the atmospheric thickness of Mars might return to the levels three billion years ago with human intervention and become the second paradise of mankind...
