The world's deepest and largest indoor pool that can be used to replicate the weightless conditions found in space is being considered for construction in Essex.
The pool is designed to help research, training and development and measures 50 metres long and 50 metres deep.
The project is estimated to cost around £40m and will also simulate deep-sea environments in addition to outer space. The facility could be used by in-training astronauts as part of their space-flight programmes.
It is aimed primarily at assisting commercial diving, remote operated vehicle work, autonomous unmanned vehicles, life science and human space flight.
The facility has even gained interest from British astronaut Tim Peake, who is currently residing on board the International Space Station (ISS).
"Exciting new project 'Blue Abyss' to build world's largest indoor pool in the UK - serving human spaceflight and more," he tweeted from the station.
Blue Abyss, the company developing the project, has created 3D footage that provides an internal view of what the pool will look like.
The pool is so large it allows for the testing of Remote Operated Vehicles which are designed to operate at the bottom of the deepest ocean trenches and are used for commercial purposes such as oil well maintenance.
The complex will house both hyper and hypo-baric chambers and a micro-gravity simulation suspension system to replicate the effects of weightlessness and low gravity in environments like those found on the Moon and Mars.
A spokesman for Blue Abyss said: "The facility aims to encourage people of all ages and abilities to discover the joys of exploring our marine environments through recreational diving, as well as providing the UK with an innovative, aquatic-based science, technology, engineering and maths education centre."
In an interview with E&T last year before he went into space, Tim Peake described some of his training prior to the launch.
It included the use of a special pool called the neutral buoyancy facility which simulated spacewalks and allowed him to learn how to control the robotic arm on the ISS in low gravity conditions.
