For 18 m\u00e5neder siden var forskerne fortvivlede, da en satellit, der skulle sende vigtige data om klimaforandringer tilbage, gik tabt under en mislykket opsendelse. ESA besluttede dog hurtigt at genopbygge CryoSat, og missionen er nu godt p\u00e5 vej til at komme p\u00e5 fode igen. N\u00e5r CryoSat-2 bliver sendt op i 2009, vil den faktisk v\u00e6re endnu mere avanceret end sin forg\u00e6nger.<\/p>\n<\/div>\n

Den store fordel ved CryoSat-2 er dens evne til at m\u00e5le \u00e6ndringer i isd\u00e6kkets tykkelse, b\u00e5de p\u00e5 land og til s\u00f8s. Dens prim\u00e6re radarinstrument og et identisk reserveinstrument vil kunne unders\u00f8ge Jordens iskapper og gletsjere under alle vejrforhold, b\u00e5de dag og nat.<\/p>\n

For at forberede sig p\u00e5 opsendelsen er en r\u00e6kke felteksperimenter ved at blive sat i gang i Arktis. Et af dem er Arctic Arc-ekspeditionen, der er en del af Det Internationale Polar\u00e5r. Ekspeditionens to belgiske opdagelsesrejsende, Alain Hubert og Dixie Dansercoer, er netop taget af sted p\u00e5 en kr\u00e6vende 110-dages vandring gennem den frosne vildmark.<\/p>\n

De to modige opdagelsesrejsende, der hver is\u00e6r tr\u00e6kker en 130 kg tung sl\u00e6de med forsyninger og udstyr, vil \u2018g\u00e5\u2019 over verdens tag, fra en \u00f8 i Sibirien til det sydlige Gr\u00f8nland. Undervejs vil de n\u00f8je registrere snedybden. S\u00e5danne m\u00e5linger er yderst nyttige til at kontrollere den metode, der anvendes til at omregne CryoSats radarm\u00e5linger til n\u00f8jagtige data om istykkelsen.<\/p>\n

Forskerne tager ogs\u00e5 ud til de isd\u00e6kkede \u00f8er p\u00e5 Svalbard i midten af april. Deres m\u00e5linger af sne og is vil blive sammenlignet med data, der sendes tilbage fra et fly, der er udstyret med en kopi af CryoSats radarinstrument.<\/p>","protected":false},"excerpt":{"rendered":"
