Kuu on liian pieni pit\u00e4m\u00e4\u00e4n ilmaa sis\u00e4ll\u00e4\u00e4n. Koska tuulia ei ole, auringonpuoleinen puoli on kuumempi kuin kiehuva vesi, mutta y\u00f6puoli on kylmempi kuin miss\u00e4\u00e4n muualla Maassa (miinus 180 astetta Celsius).<\/p>\n<\/div>\n

Suuri osa siit\u00e4, mit\u00e4 tied\u00e4mme Kuusta, on per\u00e4isin 1960- ja 1970-lukujen robottiluotaimista ja laskeutujista. Jotkut tutkijat uskoivat, ett\u00e4 Kuuhun laskeutuva avaruusalus uppoaisi sen p\u00f6lyiseen pintaan. Amerikkalaiset ja ven\u00e4l\u00e4iset laskeutujat osoittivat t\u00e4m\u00e4n oletuksen v\u00e4\u00e4r\u00e4ksi. Ne raivasivat tien ihmisten Kuun-matkoille.<\/p>\n

Vuosina 1969\u20131972 kaksitoista miest\u00e4 k\u00e4veli Kuun n\u00e4kyv\u00e4ll\u00e4 puolella. He j\u00e4ttiv\u00e4t pinnalle tieteellisi\u00e4 kokeita. He toivat mukanaan my\u00f6s l\u00e4hes 400 kg kivi\u00e4 ja maaper\u00e4\u00e4. My\u00f6hemmill\u00e4 lennoilla astronautit ajelivat Kuun pinnalla akkuk\u00e4ytt\u00f6isell\u00e4 maastopy\u00f6r\u00e4ll\u00e4.<\/p>\n

Viime vuosina monet maat ovat p\u00e4\u00e4tt\u00e4neet palata Kuuhun. Kiertoradalla olevat avaruusalukset ovat tutkineet koko pinnan eritt\u00e4in yksityiskohtaisesti. Yksi merkitt\u00e4v\u00e4 l\u00f6yt\u00f6 oli vesij\u00e4\u00e4n esiintyminen kraatterien pohjalla l\u00e4hell\u00e4 Kuun napa-alueita. Auringon s\u00e4teilt\u00e4 suojassa oleva j\u00e4\u00e4 on saattanut olla siell\u00e4 jo miljoonia vuosia. Tulevat tutkimusmatkailijat voisivat k\u00e4ytt\u00e4\u00e4 sit\u00e4 hapen tuottamiseen ja juomaveten\u00e4.<\/p>\n

Euroopan ensimm\u00e4inen kuualus oli SMART-1, joka kierteli Kuun kiertoradalla marraskuusta 2004 syyskuuhun 2006. SMART-1 otti yksityiskohtaisia kuvia pinnasta ja tutki kivien koostumusta. L\u00e4hetys p\u00e4\u00e4ttyi tarkoitukselliseen t\u00f6rm\u00e4ykseen Kuun pintaan.<\/p>","protected":false},"excerpt":{"rendered":"
