The UK is getting a new commercial astronaut training facility, called “Blue Abyss,” which will include a pool with a depth of 50 meters, Engadget reports. That’s 164 feet, which tops (or undercuts, rather) NASA’s own 12 meter buoyancy lab, and it’ll help prepare paid private astronauts for the rigors of spaceflight, along with other features of the facility, including hypobaric and hyperbaric champers, and a centrifuge for simulating high-G flight.
