400:), the astronaut feels gravity inside the pressurized suit while immersed in water. However the astronaut-spacesuit combination, when properly balanced in neutral buoyancy as when in EVA, is weightless so the astronaut is, similar to standing on ice, unable to use weight to provide a force in any vector. The vector of any force is similar, if not exactly the same in EVA and in neutral buoyancy. The magnitude of the force, if static, is very similar and if dynamic is still similar although the force and vector used in moving large objects must be carefully studied and planned to make the simulation realistic. It is the inability to use weight in any

Reduced-gravity aircraft training avoids neutral-buoyancy training's drag problem (trainees are surrounded by air rather than water), but instead faces a severe time limitation: periods of sustained weightlessness are limited to around 25 seconds, interspersed with periods of acceleration of around 2

Quickly, Environmental Research Associates' submerged testing evolved into proper neutral buoyancy simulation, featuring weighted subjects and numerous safety divers on hand during given sessions.

The main purpose for an astronaut to egress the vehicle and go EVA is often to provide a force to push, pull, crank, squeeze or transport an object. While living in normal earth gravity people do not generally recognize the use of their weight to provide a force. The simple task of opening or closing

In EVA, most work is done slowly, carefully and methodically not because of the neutral buoyancy training but because that is how a task must be performed by a pressurized astronaut in weightlessness. It takes more force to accelerate a mass to a higher velocity, and then to slow the mass back down,

is the other major concern identified in articles on neutral buoyancy simulation. Any motion in the water is subject to drag and requires a little more time (seconds) and a little more force (ounces) to compensate for drag compared to the same motion in EVA. Early in the history of neutral buoyancy

than to move it slowly to its destination. It is also easier to control its movement if it is moving slowly. Thus, the drag of water on movement in neutral buoyancy simply necessitates a slowness of movement that is also appropriate to spaceflight.
