Fair enough. It does make me wonder which is a worse environment for regolith mitigation… no atmosphere Moon, or light-atmosphere Mars?

I'm not sure that we know enough about Martian regolith to answer that yet. We really need those samples Perseverance is collecting back here in the lab...

No atmosphere on the moon means weather doesn't blow it around like on Mars. But the moon is uniquely oxygen rich from circling the earth. The same technology won't be feasible on mars.

Oxygen production is quite a bit easier on Mars, as it turns out. We've already produced O2 from the CO2 atmosphere. That's a lot easier than importing oxygen from Earth or extracting it from Lunar rock, as per this NASA proposal.

The oxygen extracted from lunar rock is a byproduct. The main goal is the aluminum, iron, and silicon that's leftover.
