Backronym
"NASA Extreme Environment Mission Operations (NEEMO) "
Someone must have really worked at getting that backronym!
Blighty's one and only astronaut, Tim Peake of the European Space Agency, has just embarked on a bold mission into an environment where few human beings have ever ventured: that of the saturation diver, semi-permanently adapted to life under high pressure and able to survive only deep underwater or inside pressurised containers …
Cousteau operated a whole list of habitats like that including a whole small "underwater city" in the Red Sea 40 or so years ago. So did US Navy, germans and a few others.
This NASA habitat is a small remnant of the glorious past compared to Sealab 2-3 (in size) or Conshelf 3 (in depth - 300m). It is a pity - we still know about the deep sea less than we know about the surface of the moon and we still do so little about it.
