Neutral Buoyancy Lab

TechRepublic visited the Neutral Buoyancy Lab at the Johnson Space Center where astronauts train for spacewalks.

This giant pool is an important piece of training for astronauts who will be completing extra vehicular activities (EVAs), or spacewalks. The pool prepares them for working in a (mostly) weightless environment, as neutral buoyancy refers to the equal tendency to float or sink.
