El\u00e4minen avaruusasemalla on melko samanlaista kuin el\u00e4minen autiomaassa. Vett\u00e4 on saatavilla hyvin v\u00e4h\u00e4n, ja jokainen pisara on arvokas.<\/p>\n<\/div>\n

Avaruussukkulassa on polttokennot, jotka tuottavat s\u00e4hk\u00f6\u00e4 yhdist\u00e4m\u00e4ll\u00e4 vety\u00e4 ja happea. Sivutuotteena syntyy suuria m\u00e4\u00e4ri\u00e4 vett\u00e4. Kansainv\u00e4lisell\u00e4 avaruusasemalla (ISS) ei kuitenkaan ole polttokennoja.<\/p>\n

L\u00e4hes kaikki ISS:ll\u00e4 k\u00e4ytett\u00e4v\u00e4 vesi on tuotava Maasta avaruussukkulalla tai automaattisilla aluksilla, kuten Ven\u00e4j\u00e4n Progress-aluksella tai ESA:n ATV-aluksella. Astronautit k\u00e4ytt\u00e4v\u00e4t t\u00e4t\u00e4 vett\u00e4 juomiseen ja ruoanlaittoon.<\/p>\n

Joissakin aiemmissa avaruusasemissa oli suihkut, mutta niit\u00e4 ei ole asennettu avaruussukkulaan eik\u00e4 ISS:\u00e4\u00e4n. Sen sijaan astronautit peseytyv\u00e4t kostealla, saippualla kostutetulla liinalla. Likaisia astioita ei my\u00f6sk\u00e4\u00e4n pest\u00e4. K\u00e4ytetyt ruokapakkaukset murskataan ja heitet\u00e4\u00e4n pois.<\/p>\n

Osa ISS:n vedest\u00e4 saadaan ilmasta ja kierr\u00e4tet\u00e4\u00e4n. Ven\u00e4l\u00e4inen laite pystyy tuottamaan t\u00e4ll\u00e4 tavalla 24 kg vett\u00e4 p\u00e4iv\u00e4ss\u00e4. Vesi puhdistetaan ja k\u00e4ytet\u00e4\u00e4n juomaveten\u00e4 tai ruoanlaittoon.<\/p>\n

WC:ss\u00e4 k\u00e4ytet\u00e4\u00e4n ilman virtausta veden sijaan ihmisen j\u00e4tteiden huuhteluun. My\u00f6s astronauttien WC:n k\u00e4yt\u00f6n yhteydess\u00e4 syntyv\u00e4 virtsa puhdistetaan ja kierr\u00e4tet\u00e4\u00e4n.<\/p>","protected":false},"excerpt":{"rendered":"
