18 kuud tagasi olid teadlased meeleheitel, kui kliimamuutuste kohta olulisi andmeid edastama pidanud satelliit l\u00e4ks kaduma stardi eba\u00f5nnestumise t\u00f5ttu. Siiski otsustas ESA kiiresti CryoSati uuesti ehitada ja missioon on n\u00fc\u00fcd taastumise teel. T\u00f5epoolest, kui CryoSat-2 2009. aastal \u00f5hku t\u00f5useb, on see veelgi v\u00f5imekam kui oma eelk\u00e4ija.<\/p>\n<\/div>\n

CryoSat-2 suurim eelis on v\u00f5ime m\u00f5\u00f5ta j\u00e4\u00e4katte paksuse muutusi nii maismaal kui ka merel. Selle p\u00f5hiradar ja selle identne varuradar suudavad uurida Maa j\u00e4\u00e4kilpe ja liustikke igasugustes ilmastikutingimustes, nii p\u00e4eval kui \u00f6\u00f6sel.<\/p>\n

Stardi ettevalmistamiseks on Arktikas k\u00e4imas mitmed v\u00e4likatsed. \u00dcks neist on \u201eArctic Arc Expedition\u201d, mis on osa Rahvusvahelisest polaaraastast. Ekspeditsiooni kaks Belgia maadeavastajat, Alain Hubert ja Dixie Dansercoer, on just asunud teele, et l\u00e4bida 110 p\u00e4eva kestev kurnav r\u00e4nnak \u00fcle j\u00e4ise looduse.<\/p>\n

Iga\u00fcks t\u00f5mbab endaga kaasa 130 kg kaaluvat kelku, millel on varud ja varustus, ning need kaks julget maadeavastajat \u2018k\u00f5nnivad\u2019 \u00fcle maailma katuse, alates \u00fchest Siberi saarest kuni L\u00f5una-Gr\u00f6\u00f6nimaani. Teel hoiavad nad hoolikalt arvestust lume s\u00fcgavuse \u00fcle. Sellised m\u00f5\u00f5tmised on \u00e4\u00e4rmiselt kasulikud, et kontrollida meetodit, mida kasutatakse CryoSati radarm\u00f5\u00f5tmiste teisendamiseks t\u00e4pseteks j\u00e4\u00e4paksuse andmeteks.<\/p>\n

Teadlased suunduvad aprilli keskel ka Svalbardi j\u00e4\u00e4ga kaetud saartele. Nende lume- ja j\u00e4\u00e4m\u00f5\u00f5tmisi v\u00f5rreldakse andmetega, mis saadetakse tagasi lennukilt, mille pardal on CryoSati radari seadme koopia.<\/p>","protected":false},"excerpt":{"rendered":"
