Life Science studies in space were initially driven by the need to
explore how man could survive spaceflight conditions; the effects
of being launched un der high accelerations, exposed to
weightlessness and radiation for different periods of time, and
returned to Earth in safety. In order to substantiate the detailed
knowledge of potentially adverse effects, many model experiments
were launched using organisms which ranged from bacteria, plants,
inverte brates, rodents and primates through to man. Although no
immediate life threatening effects were found, these experiments
can be considered today as the precursors to life science research
in space. Many unexplained effects on these life forms were
attributed to the condition of weightlessness. Most of them were
poorly recorded, poorly published, or left simply with anecdotal
information. Only with the advent of Skylab, and later Spacelab,
did the idea emerge, and indeed the infrastructure permit,
weightlessness to be considered as an ex tended tool for research
into some fundamental mechanisms or processes as sociated with the
effect of gravity on organisms at all levels. The initial hy
pothesis to extrapolate from hypergravity through 1 x g to near 0 x
g effects could no longer be retained, since many of the experiment
results were seen to contradict the models or theories in the
current textbooks of biology and physiology. The past decade has
been dedicated primarily to exploratory research."
