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

To simulate microgravity, they practice underwater using a full-scale replica of the space station. Astronaut Anne McClain describes a spacewalk as “hanging off a cliff and performing brain surgery at the same time.” Credit: Smithsonian | National Astronaut Day | Facebook

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

Suit up with NASA astronaut Anil Menon. Johnson’s Neutral Buoyancy Laboratory in Houston provides astronauts an underwater atmosphere resembling zero gravity (weightlessness) to train for spacewalks. For years, NASA Astronauts have performed spacewalks outside the International Space Station for maintenance and upgrades while wearing the Extravehicular Mobility Unit (EMU) spacesuit. The spacesuit can weigh anywhere from about 250-300 pounds on the ground. Spacewalks are some of the most physical
