Misja CryoSat zosta\u0142a przywr\u00f3cona do \u017cycia po tym, jak pierwszy satelita zosta\u0142 utracony w wyniku awarii rakiety no\u015bnej w pa\u017adzierniku 2005 roku. Teraz nowy, ulepszony CryoSat-2 jest gotowy do startu 8 kwietnia. Zostanie on umieszczony na orbicie polarnej, 700 km nad Ziemi\u0105, przez rosyjsk\u0105 rakiet\u0119 \u201eDniepr\u201d, kt\u00f3ra zostanie wystrzelona z kosmodromu Bajkonur w Kazachstanie.<\/p>\n<\/div>\n<p>Od wielu lat satelity, takie jak Envisat, sporz\u0105dzaj\u0105 mapy pokrywy lodowej z kosmosu.

Nie oddaje to jednak w pe\u0142ni obrazu tego, jak zmiany klimatu mog\u0105 wp\u0142ywa\u0107 na regiony polarne. Naukowcy s\u0105 r\u00f3wnie\u017c bardzo zainteresowani ustaleniem, jak zmienia si\u0119 grubo\u015b\u0107 lodu. Pokrywy lodowe na l\u0105dzie maj\u0105 wiele kilometr\u00f3w grubo\u015bci.
