[November 28, 2008, Oracle, AZ] Vised BioSphere2 when I was out in Tucson, AZ visiting my dad. The place is gigantic. A great engineering feat – but to think what was built is even possible on another planet is a huge stretch because of all of the manufactured equipment which would weigh tons to ship and all of the personnel needed to build it would not be able to survive long enough on a airless and food-less planet. Oh well… Anyway, the photos are shown in the order of the tour…
