If you have underwater training or testing to conduct, NASA has the Neutral Buoyancy Lab for you! Cranes! Diving suits! Workshops! Hyperbaric chambers! This video is a strange and fabulous mix of sales, engineering, and just wow as NASA shows off their 6.2 million gallon astronaut training facility pool – designed to simulate the weightlessness of space – and we get to watch. From Wikipedia:
The NBL contains full-sized mock-ups of the International Space Station (ISS) modules and payloads, visiting vehicles such as the Japan Aerospace Exploration Agency (JAXA) HTV, the European Space Agency ATV, the SpaceX Dragon, and the Orbital Sciences Corporation Cygnus. Previously there was also a mockup of the Space Shuttle payload bay, but since Space Shuttle retirement it has been removed.
