Pitk\u00e4n ty\u00f6p\u00e4iv\u00e4n j\u00e4lkeen kiertoradalla ei ole mit\u00e4\u00e4n parempaa kuin hyv\u00e4 y\u00f6uni! Avaruudessa nukkuminen on kuitenkin hieman erilaista. Siell\u00e4 ei ole yl\u00e4- tai alapuolta, ja kaikki on painotonta. Astronautit voivat kiinnitt\u00e4\u00e4 makuupussinsa sein\u00e4\u00e4n tai kattoon ja nukkua miss\u00e4 tahansa, kunhan he eiv\u00e4t leijailisi ymp\u00e4riins\u00e4 ja t\u00f6rm\u00e4isi johonkin.<\/p>\n<\/div>\n

Kansainv\u00e4lisell\u00e4 avaruusasemalla (ISS) suurin osa miehist\u00f6st\u00e4 nukkuu omissa pieniss\u00e4 hytteiss\u00e4\u00e4n. Jos niit\u00e4 ei riit\u00e4 kaikille aluksella oleville, astronautti voi nukkua jossakin ISS:n moduuleista. Amerikkalaisten hytit ovat yksityisi\u00e4, \u00e4\u00e4nieristettyj\u00e4 kopeja, joissa miehist\u00f6n j\u00e4sen voi my\u00f6s kuunnella musiikkia, k\u00e4ytt\u00e4\u00e4 kannettavaa tietokonetta ja s\u00e4ilytt\u00e4\u00e4 henkil\u00f6kohtaisia tavaroitaan suuressa laatikossa tai hytin seiniin kiinnitetyiss\u00e4 verkoissa. Hytiss\u00e4 on my\u00f6s lukuvalo, hylly ja ty\u00f6p\u00f6yt\u00e4.<\/p>\n

On t\u00e4rke\u00e4\u00e4, ett\u00e4 makuutiloissa on hyv\u00e4 ilmanvaihto. Muussa tapauksessa astronautit voivat her\u00e4t\u00e4 hapenpuutteessa ja haukkoen henke\u00e4, koska heid\u00e4n p\u00e4\u00e4ns\u00e4 ymp\u00e4rille on muodostunut kupla heid\u00e4n omasta uloshengitetyst\u00e4 hiilidioksidistaan.<\/p>\n

ISS:ll\u00e4 on 16 auringonlaskua ja -nousua 24 tunnin aikana, joten ei ole helppoa tiet\u00e4\u00e4, milloin on aika menn\u00e4 nukkumaan. Astronautit ty\u00f6skentelev\u00e4t ja nukkuvat p\u00e4ivitt\u00e4isen aikataulun mukaisesti. Heille on yleens\u00e4 varattu kahdeksan tuntia unta jokaisen teht\u00e4v\u00e4n p\u00e4iv\u00e4n p\u00e4\u00e4tteeksi. He voivat k\u00e4ytt\u00e4\u00e4 silm\u00e4lappuja tai vet\u00e4\u00e4 ikkunoiden kaihtimet alas est\u00e4\u00e4kseen auringonvalon p\u00e4\u00e4syn sis\u00e4\u00e4n nukkuessaan.<\/p>\n

Kun on aika her\u00e4t\u00e4, miehist\u00f6 k\u00e4ytt\u00e4\u00e4 her\u00e4tyskelloa tai musiikkia, jota l\u00e4hetet\u00e4\u00e4n maassa sijaitsevasta lennonjohdosta. J\u00e4nnitys avaruudessa olemisesta ja matkapahoinvointi voivat h\u00e4irit\u00e4 astronautin unirytmi\u00e4. Jotkut astronautit ovat kertoneet n\u00e4hneens\u00e4 unia ja painajaisia. Jotkut ovat jopa kertoneet kuorsaavansa avaruudessa!<\/p>","protected":false},"excerpt":{"rendered":"
