Thanks for bringing this up Emlyn. I hope everyone who speculates about a humaned mission to Mars will review the findings of the great Biosphere experiment. It is actually shocking to see how much mass and volume is evidently needed to keep even one person alive for extended periods of time in a closed system. I was quite discouraged when, with *aaaaall thaaaaat stuuuuuffff*, they *stilll* had a hell of a time. {8-[ spike
