Kansainv\u00e4lisen avaruusaseman, joka on kaikkien aikojen suurin Maata kiert\u00e4v\u00e4 esine, rakentaminen on nyt l\u00e4hes valmis. Vaikka asemalla voi t\u00e4ll\u00e4 hetkell\u00e4 asua ja ty\u00f6skennell\u00e4 jopa kuusi miehist\u00f6n j\u00e4sent\u00e4, aikaa rentoutumiseen ja maisemien ihailuun j\u00e4\u00e4 vain v\u00e4h\u00e4n. Jokaisella astronautilla on kiireinen aikataulu, johon kuuluu tieteellisten kokeiden seuranta ja toteuttaminen.<\/p>\n<\/div>\n

Monet eurooppalaisista kokeista toteutetaan ESA:n Columbus-laboratoriossa, johon on asennettu t\u00e4t\u00e4 tarkoitusta varten suunnitellut telineet. Yksi keskeisist\u00e4 kiinnostuksen kohteista on biologinen tutkimus. Miten ja miksi painovoima vaikuttaa el\u00e4vien olentojen kasvuun ja kehitykseen?<\/p>\n

ESAn Biolab-laboratoriota k\u00e4ytet\u00e4\u00e4n mikro-organismien, solujen, kudosviljelmien, pienten kasvien ja pienten selk\u00e4rangattomien, kuten matojen ja rapujen, tutkimiseen.<\/p>\n

Tutkijat voivat my\u00f6s tutkia monien eri materiaalien k\u00e4ytt\u00e4ytymist\u00e4 mikropainovoimassa. T\u00e4h\u00e4n kuuluvat esimerkiksi suurten kiteiden kasvu ja eri sulametallien sekoittaminen uusien seosten tuottamiseksi. Maapallolla tihe\u00e4mm\u00e4t nesteet vajoavat ja l\u00e4mpim\u00e4mm\u00e4t nesteet nousevat, mutta avaruudessa tilanne on toinen. Jopa vaahto ja liekit kasvavat ja k\u00e4ytt\u00e4ytyv\u00e4t avaruudessa eri tavalla.<\/p>\n

Jotkut kokeet tehd\u00e4\u00e4n Columbuksen ulkopuolella, avaruudessa. N\u00e4ihin kuuluu kolme mittalaitetta, jotka ovat mitanneet Auringon energiantuottoa viimeisten kolmen vuoden ajan. Niiden tuottamat tiedot ovat t\u00e4rkeit\u00e4, sill\u00e4 muutokset auringon aktiivisuudessa voivat vaikuttaa Maan ilmastoon. My\u00f6s erilaisia materiaaleja voidaan altistaa avaruusaseman ulkopuolella vallitsevalle ankaralle avaruusymp\u00e4rist\u00f6lle.<\/p>","protected":false},"excerpt":{"rendered":"
