Sellised satelliidid nagu GOCE, SMOS ja Cryosat aitavad meil paremini m\u00f5ista Maad ja seda, kuidas inimtegevus m\u00f5jutab loodust. Peagi lastakse orbiidile Sentinel-satelliitide perekond, et uurida maismaad ja ookeane v\u00e4ga \u00fcksikasjalikult.<br \/>Meteosat-ilmasatelliidid on muutnud meie igap\u00e4evaelu.
