I presume you are talking about Biosphere II.

Biosphere II was a marking and scientific failure.

It was an engineering success.

Think about it.

On the first try the system supported 6 people for over a year without resupply. Eventually, more oxygen was needed proving that the system was in fact air tight. The extra oxygen was needed because the concrete was absorbing it. This was a fantastic result obscured by the target of two years. If the target had been one year we would have thought: wow, they did it.

In any case, resupply of a space settlement is ok just as colonies on the American East coast were resupplied from the home country.
