    Background: U.S. Air Force pilots are taking to the water in studies aimed at determining how men will fare in the weightless, isolated darkness of space flight. They are submerged in a tank from 6 to 24 hours, serving as subjects at the U.S. Air Force Aerospace Medical Laboratory, Wright Air Development Division, Wright Paterson Air Force Base, Ohio.

    Scientists are investigating possible physiological deterioration, and physiological and psychological effects of extended periods of weightlessness on man. For certain phases, each candidate for the tank undergoes a battery of psychological tests prior to the experience and after it.

    The present study involves the use of water immersion to approximate some of the effects of weightlessness. Supported by water, normal weight sensation is altered and movements relatively effortless. In the tank, the muscular effort necessary to compensate for earth's gravitational pull no longer is necessary. This area of research has been termed hypodynamics.

    Test profile includes muscle and performance tests on and off the centrifuge, and the establishment of tolerance to G force on the centrifuge. Heart action ion the tilt table is measured and each man is exposed to temperatures of 100øF, for one hour.

    After the six hour submersion in the tank, the man repeats the test cycle to study the physiological effects of simulated weightlessness. This is repeated after similar 2 and 14 hour periods in the thank.
