Wasn’t that the one Steve Bannon was involved in, of all people?
I wasn’t necessarily thinking of Biosphere 2, just the fact that you won’t be getting a resupply on short notice.
The problem is that Mars is 6-12 months away depending on launch window, at least with current rockets. If something goes wrong you must be able to respond locally and at least survive. The Moon is 3 days away (ish) and LEO is hours away (including time to align and dock).
If you want to send people to Mars you need to build a Mars sim on Earth and actually test your life support systems.
