At bo p\u00e5 en rumstation er lidt som at bo i en \u00f8rken. Der er meget lidt vand til r\u00e5dighed, og hver eneste dr\u00e5be er dyrebar.<\/p>\n<\/div>\n

Rumf\u00e6rgen har br\u00e6ndselsceller, der omdanner brint og ilt til elektricitet. Der dannes store m\u00e6ngder vand som et biprodukt. Men der er ingen br\u00e6ndselsceller p\u00e5 Den Internationale Rumstation (ISS).<\/p>\n

N\u00e6sten alt det vand, der bruges p\u00e5 ISS, skal transporteres fra Jorden med rumf\u00e6rgen eller automatiske rumfart\u00f8jer som f.eks. Ruslands Progress eller ESA\u2019s ATV. Astronauterne bruger vandet til at drikke og til at tilberede mad.<\/p>\n

Nogle tidligere rumstationer var udstyret med brusere, men s\u00e5danne findes hverken i rumf\u00e6rgen eller p\u00e5 ISS. I stedet bruger astronauterne en fugtig, s\u00e6beindsmurt klud til at vaske sig med. Der vaskes heller ikke snavset service. Brugte madbeholdere knuses og smides v\u00e6k.<\/p>\n

En del af vandet p\u00e5 ISS udvindes fra luften og genbruges. Et russisk anl\u00e6g kan p\u00e5 denne m\u00e5de producere 24 kg vand om dagen. Vandet renses og bruges til drikkevand eller til madlavning.<\/p>\n

Toilettet bruger en luftstr\u00f8m i stedet for vand til at skylle aff\u00f8ringen v\u00e6k. Urinen, der dannes, n\u00e5r astronauterne benytter toilettet, renses og genbruges ligeledes.<\/p>","protected":false},"excerpt":{"rendered":"
