Et nyt kapitel inden for jordobservation begyndte kl. XX.XX CEST den 8. oktober 2005, da Europas CryoSat blev opsendt fra Plesetsk-kosmodromen i det nordlige Rusland. Rumfart\u00f8jet, der vejer 711 kg, er den f\u00f8rste af ESA\u2019s Earth Explorer-missioner \u2013 en ny serie af satellitter, der skal unders\u00f8ge de store forandringer, der finder sted p\u00e5 vores planet.<\/p>\n<\/div>\n

Cryosat blev bragt i en 720 km lang, n\u00e6sten pol\u00e6r bane af en Rockot-raket \u2013 det var f\u00f8rste gang, ESA har anvendt et af disse l\u00f8ftefart\u00f8jer. Som en del af ESAs \u00bbLiving Planet\u00ab-program skal Cryosat i tre \u00e5r foretage de mest n\u00f8jagtige m\u00e5linger af polarkalotterne nogensinde.<\/p>\n

Dens radarh\u00f8jdem\u00e5ler vil kunne registrere \u00e6ndringer p\u00e5 blot f\u00e5 centimeter i tykkelsen af iskapperne p\u00e5 land og til s\u00f8s. Disse oplysninger er af afg\u00f8rende betydning, da iskapperne i Arktis og Antarktis spiller en afg\u00f8rende rolle for klodens klima.<\/p>\n

Mange forskere frygter, at den globale opvarmning vil f\u00e5 store dele af isen til at smelte i l\u00f8bet af de kommende \u00e5rtier. Dette kan medf\u00f8re dramatiske \u00e6ndringer i havstr\u00f8mmene i Nordatlanten, som holder Vesteuropa varmt om vinteren.<\/p>\n

\u201cMed CryoSat og hele Living Planet-programmet stiller ESA v\u00e6rkt\u00f8jer til r\u00e5dighed, der kan im\u00f8dekomme alle europ\u00e6eres bekymringer vedr\u00f8rende klimaforandringer og livets fremtid p\u00e5 Jorden,\u201d sagde Jean-Jacques Dordain, generaldirekt\u00f8r for ESA.<\/p>\n

Der er planlagt yderligere fem Earth Explorer-missioner. De skal unders\u00f8ge mange forskellige aspekter af milj\u00f8et. Heriblandt havcirkulation, jordfugtighed og havets saltholdighed, globale vinde, Jordens magnetfelt samt skyernes indvirkning p\u00e5 den indfaldende solstr\u00e5ling.<\/p>","protected":false},"excerpt":{"rendered":"
