Abstract

For the 17- and 120-day isolation campaigns within project SIRIUS, the stock of personal hygiene items (PHIs), underwear and clothes was supplied in compliance with the current ISS rates of consumption. Over 120 questionnaires filled by the human subjects made possible estimation of the total weight of these provisions in a mission to the Moon, and get feedback about the hygienic means and methods. The hygienic comfort of 6 crewmembers of the 120-d isolation campaign required more than 500 kg of underwear, bedclothes, towels, personal hygiene items, pieces of toilet and household essentials, which are also musts in a mission to the Moon and back. Long-duration missions and sojourns on lunar and Mars bases will call for designing arrangements for personal hygiene, shower, dish washing and laundry integrated with regenerative life support systems. Results of the investigation showed effectiveness of the sanitation and hygiene system and its functional significance.
