NASA Extreme Environment Mission Operations, or NEEMO, [1] is a NASA analog mission that sends groups of astronauts, engineers and scientists to live in the Aquarius underwater laboratory, the world's only undersea research station, for up to three weeks at a time in preparation for future space exploration.
Scientists on the Aquarius are often called "aquanauts" (as they live underwater at depth pressure for a period equal to or greater than 24 continuous hours without returning to the surface). A technique known as saturation diving allows the aquanauts to live and work underwater for days or weeks at a time. After twenty-four hours underwater at ...
Actual water use during space missions is typically double the given value, mainly due to non-biological use (e.g. showering). Additionally, the volume and variety of waste products varies with mission duration to include hair, finger nails, skin flaking, and other biological wastes in missions exceeding one week in length.
The space station is whizzing around Earth at about five miles per second (18,000 mph), according to NASA. That means time moves slower for the astronauts relative to people on the surface. Now ...

According to Lunine, "oceans" have been defined as "stable, globe-girdling bodies of liquid water." [13] In addition, "Ocean worlds is the label given to objects in the solar system that host stable, globe-girdling bodies of liquid water," in contrast to the terms "'ocean planet' and 'water world', both of which refer to exoplanets (planets orbiting other stars) with substantial mass fractions ...
A Stanford torus interior (cutaway view) Interior view of a large scale O'Neill cylinder, showing alternating land and window stripes. A space settlement (also called a space habitat, spacestead, space city or space colony) is a settlement in outer space, sustaining more extensively habitation facilities in space than a general space station or spacecraft.
Through diving surveys in Aarhus Bay [in Denmark] we will determine how widespread coastal settlements were compared to those in the interior and determine how marine resources were exploited 9000 ...
