F\u00f6r 18 m\u00e5nader sedan var forskarna f\u00f6rtvivlade n\u00e4r en satellit, som skulle skicka tillbaka viktiga data om klimatf\u00f6r\u00e4ndringarna, gick f\u00f6rlorad till f\u00f6ljd av ett misslyckat uppskjutningsf\u00f6rs\u00f6k. ESA beslutade dock snabbt att bygga om CryoSat, och uppdraget \u00e4r nu p\u00e5 god v\u00e4g att \u00e5terupptas. N\u00e4r CryoSat-2 skjuts upp 2009 kommer den faktiskt att ha \u00e4nnu st\u00f6rre kapacitet \u00e4n sin f\u00f6reg\u00e5ngare.<\/p>\n<\/div>\n

Den stora f\u00f6rdelen med CryoSat-2 \u00e4r dess f\u00f6rm\u00e5ga att m\u00e4ta f\u00f6r\u00e4ndringar i ist\u00e4ckets tjocklek, b\u00e5de p\u00e5 land och till havs. Dess prim\u00e4ra radarinstrument och en identisk reserv kommer att kunna studera jordens ist\u00e4cken och glaci\u00e4rer i alla v\u00e4derf\u00f6rh\u00e5llanden, b\u00e5de dag och natt.<\/p>\n

F\u00f6r att f\u00f6rbereda lanseringen p\u00e5b\u00f6rjas nu ett antal f\u00e4ltf\u00f6rs\u00f6k i Arktis. Ett av dessa \u00e4r Arctic Arc-expeditionen, som ing\u00e5r i det internationella polar\u00e5ret. Expeditionens tv\u00e5 belgiska uppt\u00e4cktsresande, Alain Hubert och Dixie Dansercoer, har just gett sig iv\u00e4g p\u00e5 en kr\u00e4vande 110-dagars vandring genom den frusna vildmarken.<\/p>\n

De tv\u00e5 or\u00e4dda uppt\u00e4cktsresande kommer, var och en dragande en 130 kg tung sl\u00e4de med f\u00f6rn\u00f6denheter och utrustning, att \u2018vandra\u2019 \u00f6ver v\u00e4rldens tak, fr\u00e5n en \u00f6 i Sibirien till s\u00f6dra Gr\u00f6nland. Under resan kommer de att noggrant dokumentera sn\u00f6djupet. S\u00e5dana m\u00e4tningar \u00e4r oerh\u00f6rt anv\u00e4ndbara f\u00f6r att kontrollera den metod som anv\u00e4nds f\u00f6r att omvandla CryoSats radarm\u00e4tningar till exakta uppgifter om istjockleken.<\/p>\n

Forskarna kommer ocks\u00e5 att bege sig till de isbelagda \u00f6arna p\u00e5 Svalbard i mitten av april. Deras sn\u00f6- och ism\u00e4tningar kommer att j\u00e4mf\u00f6ras med data som skickas tillbaka fr\u00e5n ett flygplan utrustat med en kopia av CryoSats radarinstrument.<\/p>","protected":false},"excerpt":{"rendered":"
