The Neutral Buoyancy Laboratory is a busy place! In this timelapse, NASA astronauts Sunita Williams and Josh Cassada suit up and enter the 6.2 million gallon pool to practice for spacewalks. Meanwhile, water survival training is taking place on the other side of the NBL, designed large enough to accompany two activities taking place at once.

Ever wondered how neutral buoyancy works? One of our engineering divers at the Neutral Buoyancy Laboratory demonstrates the concept with a lift bag! When neutrally buoyant, the bag doesn’t move. When positively or negatively buoyant, the bag will float or sink because of the change in the buoyant force acting upon it. During their training for space walks, astronauts are made neutrally buoyant to simulate weightlessness. | NASA's Johnson Space Center

We got to hang out with divers and admin at the stunning Neutral Buoyancy Laboratory to check out their amazing pool and talk about Splashball! Be sure to check out all of our 2019 #USAWPTexasTour videos! | USA Water Polo
