The workaday world of NASA-439's cargo bay during today's mission.  Most of the OIB science gear and operators reside here, for eight hours every flight day.  The science equipment racks, most seats, and the comfort facilities are mounted on standard aluminum cargo pallets and conveniently "roll on/roll off" directly from the C-130's cargo ramp during integration and deintegration.  Survival equipment, intercom cords, headsets, spare computer network cables and various other prosaic but necessary items are visible throughout the bay.  Windows are few, and prized.
