Att bo p\u00e5 en rymdstation \u00e4r ungef\u00e4r som att bo i en \u00f6ken. Det finns v\u00e4ldigt lite vatten att tillg\u00e5 och varje droppe \u00e4r dyrbar.<\/p>\n<\/div>\n

Rymdf\u00e4rjan har br\u00e4nsleceller som kombinerar v\u00e4te och syre f\u00f6r att alstra elektricitet. Stora m\u00e4ngder vatten bildas som en biprodukt. Men det finns inga br\u00e4nsleceller p\u00e5 den internationella rymdstationen (ISS).<\/p>\n

N\u00e4stan allt vatten som anv\u00e4nds p\u00e5 ISS m\u00e5ste transporteras upp fr\u00e5n jorden med rymdf\u00e4rjan eller automatiska farkoster, s\u00e5som Rysslands Progress eller ESA:s ATV. Astronauterna anv\u00e4nder vattnet f\u00f6r att dricka och tillaga mat.<\/p>\n

Vissa tidigare rymdstationer var utrustade med duschar, men s\u00e5dana finns varken p\u00e5 rymdf\u00e4rjan eller p\u00e5 ISS. Ist\u00e4llet anv\u00e4nder astronauterna en fuktig, tv\u00e5lindr\u00e4nkt trasa f\u00f6r att tv\u00e4tta sig. Man diskar inte heller smutsig disk. Anv\u00e4nda matbeh\u00e5llare krossas och kastas bort.<\/p>\n

En del av vattnet p\u00e5 ISS utvinns ur luften och \u00e5tervinns. En rysk anl\u00e4ggning kan p\u00e5 detta s\u00e4tt producera 24 kg vatten per dag. Vattnet renas och anv\u00e4nds som dricksvatten eller vid matlagning.<\/p>\n

Toaletten anv\u00e4nder en luftstr\u00f6m ist\u00e4llet f\u00f6r vatten f\u00f6r att spola bort avf\u00f6ringen. Urinen som bildas n\u00e4r astronauterna anv\u00e4nder toaletten renas och \u00e5tervinns ocks\u00e5.<\/p>","protected":false},"excerpt":{"rendered":"
