Today's tour was at the Neutral Buoyancy Laboratory (NBL). This is NASA's incredibly large pool with mock-ups of most of the US segments and truss structure of the International Space Station. I have been to the pool before (thanks Uncle Howard!), but now that I am a certified diver I have a much different appreciation for all of the logistics associated with operating this tank.
|Welcome to the NBL with 6 ft thick reinforced concrete for the floor and a hyperbaric chamber just in case!|

|This is the "control center" where test directors sit during EVA test runs. Lots of cameras!|
