Between the Crew Quarters (40′ shipping container) and Workshop (20′ shipping container) there will be a bridge. It will not offer a pressure door, although we may add a standard interior door for the sake of noise mitigation from the Workshop into the Crew Quarters. We have given this passage a good deal of consideration, with concern for the width and height being such that the average crew member does not have to mind his or her head or shoulders when moving tools or supplies, yet the passage is not so large that it cannot be closed. The step-up height is identical to that into the airlock, so the crew will be accustomed to the motion. The bridge must hold a hermetic seal, be insulated (as with the rest of the living space), and offer a stable, non-slip floor plate.

Colleen removes a foam panel from SAM at Biosphere 2 The first effort was to remove a 34″ wide by 72″ tall door way. Kai applied the cutting wheel while Colleen and our new volunteer Luna Powell took turns with the angle grinder to remove the rivets. We then peeled the exterior aluminum and interior stainless steel skins from the foam, used a reciprocating saber (“saws-all”) to complete the cut across the full depth, and pushed the foam panel out of the wall space.
