This book focuses on all of the major problems associated with
the absence of body weight in space, by analyzing effects,
adaption, and re-adaptation upon returning to Earth, using sound
scientific principles embedded in a historical context. Serious
problems for space travelers range from Space Motion Sickness
(SMS) to recently discovered ocular effects that may permanently
impair vision. Fluid loss and shifts, spinal changes, and bone
and muscle loss are also all results of weightlessness.

Starting with a brief definition and history of
weightlessness, the authors then address in detail each
problem as well as the countermeasures aimed at alleviating them.
In some cases, alternative hypotheses regarding what can and
should be attempted are also presented. As plans for long-term
missions to the Moon and Mars develop, it will be essential to
find countermeasures to weightlessness that are effective for
missions that could span years.
