The Neutral Buoyancy Lab Experience

The Neutral Buoyancy Lab (NBL) serves as a critical training environment for astronauts, simulating the experience of weightlessness in space. This massive facility, with its 6.2 million gallons of water, allows astronauts to practice maneuvers and familiarize themselves with the complexities of operating in a spacesuit. Training in the NBL requires astronauts to don their suits, a process that can take about 45 minutes, emphasizing the importance of meticulous preparation before they can enter the water. Once submerged, astronauts rehearse tasks they would perform during spacewalks, ensuring they know the layout and mechanics of the International Space Station (ISS) while adjusting to the sensations of weightlessness.
