Azul: We're at the NASA pool watching some astronauts get suited up for
some test rounds.
Robert: Hi, I'm Robert Knight [SP]. I'm one of the suit and tool engineers
over here at the NBL, otherwise known as the Neutral Buoyancy Laboratory.
Basically, what I do is I get people fitted into a suit, and then once we
get them into the suit, we end up putting them in the training facility
Azul: How much water does this hold?
Robert: A little under 6.3 million gallons of water.
Robert: Most of the structure that's in the pool right now is mockups of
the space station.
Azul: Now how much hydration do they get in a suit like that?
Robert: We give them what we call a DIDB, a Disposable In-Suit Drink Bag,
and we can fill this bag up with either 21 or 32 ounces of water. They're
going to be lowered in on this crane. The crane is going to submerge them
in the pool. They've got weights attached to their feet so they'll sink to
the bottom and then the support divers will take the weights off because
being submerged in water is the closest they can get to zero gravity
without being in outer space.
Seth: That's CamelBak, hanging out at the NASA Neutral Buoyancy Lab
checking out the space suits.
