Neutral Buoyancy Lab

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.

Everybody in the pool

Each astronaut in the pool is accompanied by 4 divers. Since EVAs can take hours, those divers take shifts.

Outside of the pool

Training for spacewalks includes not just those who will be outside the International Space Station, but the crew monitoring and the crew operating the robotic arm. The pool has its own control room, shown here.
