In the next century, mankind will expand its activity to the moon and
Mars. At that time, humans will be exposed to a low and micro-gravity
environment in long term which causes physiological and psychological
problems. The authors propose an artificial gravity space station for
a research laboratory on human physiology and psychology at various gr
avity levels. The baseline specifications and the configuration of the
space station are shown. Reviewing the history of manned space flight
, the necessity of the research on an artificial gravity space station
is discussed, including themes of research to be conducted on the sta
tion and the application of its results. Technical issues for realizat
ion of the space station such as environmental factors, system functio
n and assembly scenario are also discussed.
