As important, the oxygen is produced from locally-sourced CO2, not from water brought from elsewhere.

So it's not limited by the rocket's or craft's carrying capacity.
Is there any evidence of this or is it just "NASA says" as usual?

- It is the purpose of the MOXIE unit, which they had proved a small amount from back in 2021. OG press release
