16. veebruaril lastakse ESA satelliit Sentinel-3 Maa orbiidile! Sentinel-3 on uusim liige k\u00f5rgtehnoloogiliste satelliitide perekonnas, mille \u00fclesandeks on uurida meie planeedi maismaad, ookeane ja atmosf\u00e4\u00e4ri.<\/p>\n<\/div>\n

Sentinel-3 keskendub meie ookeanidele. Ookeanide seire, mis h\u00f5lmab 70% planeedist, v\u00f5imaldab meil hinnata, kui terve on Maa. See, mis meredes toimub, m\u00f5jutab meid k\u00f5iki, olenemata sellest, kus me elame. Meie planeedi vesi on oluline ressurss, mida peame kaitsma.<\/p>\n

Sentinel-3 hakkab tiirlema \u00fcle 800 km k\u00f5rgusel Maa pinnast \u2013 see on Maast isegi kaugemal kui Rahvusvaheline Kosmosejaam, mis tiirleb meie planeedi \u00fcmber umbes 400 km k\u00f5rgusel. Sellelt vaatepunktilt m\u00f5\u00f5dab satelliit merepinna temperatuuri, v\u00e4rvi ja k\u00f5rgust ning merej\u00e4\u00e4 paksust. Need m\u00f5\u00f5tmised on v\u00e4ga olulised, sest nende abil saame j\u00e4lgida, kuidas merepinna tase muutub, kui palju on reostust ja kui heas seisundis on mereelu.<\/p>\n

Kui Sentinel-3 ei j\u00e4lgi ookeani, aitab ta oma kaaslase, satelliidi Sentinel-2 t\u00f6\u00f6d, j\u00e4lgides Maa maismaad. Ta m\u00f5\u00f5dab j\u00e4rvede ja j\u00f5gede veetaset ning j\u00e4lgib isegi ohtlikke metsatulekahjusid.<\/p>\n

Orbiidil on juba kaks Sentinel-satelliiti ning p\u00e4rast Sentinel-3-t on kavas veel neli. Iga satelliit t\u00f6\u00f6tab v\u00e4hemalt seitse aastat. Missiooni teadlased loodavad siiski, et need t\u00f6\u00f6tavad veelgi kauem, ning on varustanud satelliidid piisava k\u00fctusekogusega, et need suudaksid t\u00f6\u00f6tada 12 aastat katkematult!<\/p>\n

Huvitav fakt:<\/b> Rakett, mis viib Sentinel-3 orbiidile, on modifitseeritud SS-19 mandritevaheline ballistiline rakett. See oli algselt kavandatud s\u00f5jariistaks, kuid on \u00fcmber ehitatud rahuotstarbeliseks kasutamiseks. See sobib v\u00e4ga h\u00e4sti kokku Sentinel-3 missiooniga kaitsta Maad!<\/p>","protected":false},"excerpt":{"rendered":"
