Buoyancy
In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.

Density
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.

Float (nautical)
Floats (also called pontoons) are airtight hollow structures, similar to pressure vessels, designed to provide buoyancy in water.

Micro-g environment
The term micro-g environment (also µg, often referred to by the term microgravity) is more or less a synonym for weightlessness and zero-g, but indicates that g-forces are not quite zero—just very small.

NASA
The National Aeronautics and Space Administration (NASA) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research.

Neutral buoyancy simulation as a training aid
Neutral buoyancy simulation with astronauts immersed in a neutral buoyancy pool, in pressure suits, can help to prepare astronauts for the difficult task of working while outside a spacecraft in an apparently weightless environment.

Personal flotation device
A personal flotation device (abbreviated as PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a piece of equipment designed to assist a wearer to keep afloat in water.

Roscosmos
The Roscosmos State Corporation for Space Activities (Государственная корпорация по космической деятельности «Роскосмос»), commonly known as Roscosmos (Роскосмос), is a state corporation responsible for the space flight and cosmonautics program for the Russian Federation.

Scuba diving
Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater.

Seaplane
A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water.
New!!: Neutral buoyancy and Seaplane · See more »
Ship
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying passengers or goods, or in support of specialized missions, such as defense, research and fishing.

Space suit
A space suit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes.

Space Systems Laboratory
The Space Systems Laboratory (SSL) is part of the Aerospace Engineering Department and A. James Clark School of Engineering at the University of Maryland in College Park, Maryland.

Submarine
A submarine (or simply sub) is a watercraft capable of independent operation underwater.

Submersible
A submersible is a small vehicle designed to operate underwater.
New!!: Neutral buoyancy and Submersible · See more »
Swim bladder
The swim bladder, gas bladder, fish maw or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to waste energy in swimming.

Swimming
Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival.
