Mutta mit\u00e4 tapahtuu kansainv\u00e4lisell\u00e4 avaruusasemalla, jossa miehist\u00f6 kokee 16 auringonnousua ja -laskua 24 tunnin aikana?<\/p>\n<\/div>\n<p>Astronautit voivat k\u00e4rsi\u00e4 unih\u00e4iri\u00f6ist\u00e4 avaruudessa, aivan kuten mekin.

Maanantaista perjantaihin heill\u00e4 on hyvin j\u00e4sennelty p\u00e4iv\u00e4rutiini: he ty\u00f6skentelev\u00e4t jopa 10 tuntia, mink\u00e4 j\u00e4lkeen seuraa kahdeksan tunnin unijakso. Ateriat nautitaan m\u00e4\u00e4r\u00e4tyin\u00e4 aikoina, samoin kuin rentoutumishetket, tilannekatsaukset sek\u00e4 ajat, jotka on varattu yhteydenpitoon perheen ja yst\u00e4vien kanssa, yksityisyydelle ja vapaa-ajan harrastuksille.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3032\" data-credit=\"NASA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2007\/11\/Nespoli_inside_sleeping_bag_in_Harmony2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2007\/11\/nespoli_inside_sleeping_bag_in_harmony2\/17894684-2-eng-GB\/Nespoli_inside_sleeping_bag_in_Harmony.jpg\" alt=\"Nespoli inside sleeping bag in Harmony\"><figcaption>Nespoli makuupussissa Harmony-mallissa<\/figcaption><\/figure>\n<p>Lauantai kuluu lis\u00e4\u00e4 ty\u00f6h\u00f6n, huoltot\u00f6ihin, siivoukseen ja omaan aikaan.
