新型宇宙トイレの開発

抄録

The improvement of space technology has enabled astronauts to stay for a long time in space. But microgravity makes their living hard. Excretion is one of the inconveniences. Crew’s stools and urine will float in the air under microgravity. The current space toilet system has complicated structure and many problems such as fragility, insanitation, requiring prior training and so on. When it is under the service, astronauts have to repair it about for an hour. It is necessary for them to use it comfortably. In order to solve such problems, we report the development of a new space toilet system which is tough, clean and needs no training.
