Uusi luku maapallon havainnoinnissa alkoi 8. lokakuuta 2005 kello XX.XX CEST, kun eurooppalainen CryoSat-satelliitti laukaistiin Plesetskin avaruuskeskuksesta Pohjois-Ven\u00e4j\u00e4lt\u00e4. T\u00e4m\u00e4 711 kg painava avaruusalus on ensimm\u00e4inen ESA:n Earth Explorer -ohjelman satelliiteista \u2013 uudesta satelliittisarjasta, jonka avulla tutkitaan maapallollamme tapahtuvia merkitt\u00e4vi\u00e4 muutoksia.<\/p>\n<\/div>\n

Cryosat laukaistiin Rockot-kantoraketilla 720 km:n korkeudelle l\u00e4hes polaariselle kiertoradalle. T\u00e4m\u00e4 oli ensimm\u00e4inen kerta, kun ESA k\u00e4ytti t\u00e4llaista kantorakettia. Cryosat on osa ESA:n Living Planet -ohjelmaa, ja sen teht\u00e4v\u00e4n\u00e4 on kolmen vuoden ajan suorittaa historian tarkimmat mittaukset napaj\u00e4\u00e4tik\u00f6ist\u00e4.<\/p>\n

Sen tutka-korkeusmittari havaitsee vain muutaman senttimetrin muutokset maa- ja merij\u00e4\u00e4peitteiden paksuudessa. N\u00e4m\u00e4 tiedot ovat elint\u00e4rkeit\u00e4, sill\u00e4 arktisen ja antarktisen j\u00e4\u00e4peitteen merkitys planeetan ilmastolle on ratkaiseva.<\/p>\n

Monet tutkijat pelk\u00e4\u00e4v\u00e4t, ett\u00e4 ilmaston l\u00e4mpeneminen sulattaa suuren osan j\u00e4\u00e4peitteest\u00e4 seuraavien vuosikymmenien aikana. T\u00e4m\u00e4 voisi muuttaa dramaattisesti Pohjois-Atlantin merivirtauksia, jotka pit\u00e4v\u00e4t L\u00e4nsi-Euroopan l\u00e4mpim\u00e4n\u00e4 talvella.<\/p>\n

\u201cCryoSat-satelliitin ja koko Living Planet -ohjelman avulla ESA tarjoaa v\u00e4lineit\u00e4, joilla voidaan vastata kaikkien eurooppalaisten huoliin ilmastonmuutoksesta ja el\u00e4m\u00e4n tulevaisuudesta maapallolla\u201d, sanoi ESA:n p\u00e4\u00e4johtaja Jean-Jacques Dordain.<\/p>\n

Suunnitteilla on viel\u00e4 viisi Earth Explorer -tutkimuslentoa. Niiss\u00e4 tutkitaan monia erilaisia ymp\u00e4rist\u00f6\u00f6n liittyvi\u00e4 ilmi\u00f6it\u00e4. N\u00e4it\u00e4 ovat muun muassa merivirtaukset, maaper\u00e4n kosteus ja meren suolapitoisuus, maailmanlaajuiset tuulet, maapallon magneettikentt\u00e4 sek\u00e4 pilvipeitteen vaikutus maapallolle saapuvaan auringon s\u00e4teilyyn.<\/p>","protected":false},"excerpt":{"rendered":"
