月、火星居住に向け共同研究　人工重力施設など構想―京都大と鹿島

　京都大学と鹿島建設は５日、人類が月や火星で生活する時代に必要となる、重力を人工的に生み出す居住施設構想について共同研究を始めると発表した。
　構想は２１世紀後半、人類が月や火星への移住を実現すると想定。月や火星は地球に比べて重力が小さく、長期間の滞在は健康や発育などへの影響が懸念される。このため、施設全体が回転するグラスのような形をした居住施設を建設。遠心力で地球環境と同等の重力を人工的に発生させる。（2022/07/05-21:33）

Kyoto University and Kajima Corp. will launch joint research on housing facilities with artificial gravity, needed for human habitation on the moon and Mars.
   The research is based on the assumption that human beings will realize permanent presence on the moon and Mars in the second half of the 21st century.
   Due to weaker gravity there compared to Earth, however, concerns linger that staying on the moon or Mars for long periods of time may affect people's health.
   The Japanese university and the general contractor therefore aim to build glass-shaped housing facilities that can rotate and create the same level of gravity as that on Earth using centrifugal force.
   They plan to reproduce in the facilities an environment similar to the ecosystem on Earth. The research project also aims to develop a train-style transportation system linking Earth with the moon and Mars.
