Timp de multe secole, singura modalitate de a avea o vedere bun\u0103 asupra unei zone \u00eentinse era s\u0103 urci pe un teren mai \u00eenalt. Apoi, inventarea baloanelor \u0219i a aeronavelor a facilitat considerabil observarea P\u0103m\u00e2ntului.<\/p>\n<\/div>\n

\u00cen era spa\u021bial\u0103, sateli\u021bii au fost folosi\u021bi din ce \u00een ce mai mult pentru a studia fiecare aspect al planetei noastre.<\/p>\n

Deoarece observ\u0103 P\u0103m\u00e2ntul de la mare distan\u021b\u0103, ace\u0219tia sunt adesea denumi\u021bi sateli\u021bi de \u201cteledetec\u021bie\u201d.<\/p>\n

Cele mai detaliate imagini ale suprafe\u021bei \u0219i atmosferei P\u0103m\u00e2ntului sunt transmise de sateli\u021bii afla\u021bi pe orbite joase, care trec peste polul nord \u0219i polul sud.<\/p>\n

Pe m\u0103sur\u0103 ce P\u0103m\u00e2ntul se rote\u0219te sub ei, ace\u0219ti sateli\u021bi pot realiza imagini ale \u00eentregii planete \u2013 band\u0103 cu band\u0103 \u2013 la fiecare c\u00e2teva zile.<\/p>\n

Sateli\u021bii afla\u021bi pe orbite polare studiaz\u0103 stratul de ghea\u021b\u0103 \u0219i z\u0103pad\u0103, utilizarea terenurilor, poluarea aerului \u0219i a apei, precum \u0219i condi\u021biile meteorologice locale. Sateli\u021bii ESA afla\u021bi pe orbite polare sunt Satelitul European de Teledetec\u021bie (ERS-2) \u0219i satelitul de monitorizare a mediului, Envisat.<\/p>\n

Alte nave spa\u021biale observ\u0103 \u00een mod continuu aceea\u0219i zon\u0103 a P\u0103m\u00e2ntului, \u00een timp ce orbiteaz\u0103 la o altitudine de 36.000 km deasupra ecuatorului. Acest lucru le ofer\u0103 o perspectiv\u0103 mai larg\u0103, dar \u00eenseamn\u0103 c\u0103 nu pot vedea P\u0103m\u00e2ntul cu acela\u0219i nivel de detaliu.<\/p>\n

P\u00e2n\u0103 \u00een prezent, Europa a lansat opt sateli\u021bi meteorologici, denumi\u021bi Meteosat, pe acest tip de orbit\u0103 \u201cgeosta\u021bionar\u0103\u201d.<\/p>","protected":false},"excerpt":{"rendered":"
