ESA uue Maa-vaatlus satelliitide Sentinel-seeria esimene satelliit on toimetatud Euroopa Kourou kosmodroomile Prantsuse Guajaanas L\u00f5una-Ameerikas. P\u00e4rast seitsmeaastast projekteerimist, kokkupanekut ja katsetamist lastakse Sentinel-1A 3. aprillil 2014 orbiidile \u201eSojuz\u201c-raketiga.<\/p>\n<\/div>\n

Satelliidi kaal on stardil tagasihoidlik 2,3 tonni. Sentinel-1A konstruktsioon on \u00fcsna ebatavaline: sellel on kaks 10 m pikkust p\u00e4ikesepaneeli ja 12 m pikkune radarantenni. P\u00e4ikesepaneelid ja antenn on kokku volditud, et need mahuksid raketi ninaosas asuvasse kaitsekatte sisse. P\u00e4rast satelliidi kosmosesse viimist avatakse need \u00fcheaegselt, kuid hoolikalt planeeritud j\u00e4rjekorras, mille l\u00e4biviimine v\u00f5tab aega umbes 10 tundi.<\/p>\n

Kui Sentinel-1A hakkab t\u00f6\u00f6tama, hakkab selle k\u00f5rgtehnoloogiline radar seadeldis pildistama Maa pinda 24 tundi \u00f6\u00f6p\u00e4evas, seitse p\u00e4eva n\u00e4dalas, olenemata sellest, kas taevas on pilvine v\u00f5i pime.<\/p>\n

Sentinel-1A andmeid kasutatakse paljude erinevate tegevuste jaoks. Selle abil kaardistatakse muutusi Arktika merej\u00e4\u00e4katte pindalas, j\u00e4lgitakse naftalekkeid merel ning tuvastatakse laevu. Selle abil uuritakse metsa-, vee- ja mullavarusid ning pakutakse abi kriisiolukordades. Tegelikult on see ainus Euroopa satelliit, mis on spetsiaalselt loodud kiireks reageerimiseks sellistele h\u00e4daolukordadele nagu \u00fcleujutused ja maav\u00e4rinad.<\/p>\n

Teine, identne Sentinel-1 satelliit on kavas orbiidile saata j\u00e4rgmisel aastal. Koos j\u00e4tkavad need ERS-1, ERS-2 ja Envisat poolt alustatud pikaajalist radaruuringute traditsiooni.<\/p>","protected":false},"excerpt":{"rendered":"
