The Neutral Buoyancy Lab was our next stop. The huge pool is 40 feet deep and 200 feet long, with 6.2 million gallons of water. In the pool are mockups of the ISS and the shuttle payload bay. I presume they’ll be taking out the shuttle bay.
There was a training exercise going on while we were there. Two of the people who normally train the astronauts were in the suits. So it was a ‘training the trainers’ day. Along with the people in spacesuits, there were several divers around them.
