Selle \u00fclesanne on testida uusi tehnoloogiaid, uurida meie planeedi \u00fcmber puhuvaid tuuli ja saata andmeid meteoroloogidele, et parandada ilmaprognoose kogu planeedi ulatuses!<\/p>\n<\/div>\n<p>Aeolus oli teedrajav satelliit, mis suutis kosmosest laseriga m\u00f5\u00f5ta \u00fclemaailmseid tuuli. Kogutud andmed j\u00f5udsid ilmateadlasteni kolme tunni jooksul, mist\u00f5ttu oli see suurep\u00e4rane vahend maailma suurimatele ilmateenistustele, sealhulgas Euroopa Keskpika Ajavahemiku Ilmaprognooside Keskusele ja Suurbritannia Met Office\u2019ile. Aeolust on kasutatud ka vulkaaniliste pilvede uurimiseks, Sahara tolmu m\u00f5istmiseks ja isegi ookeani biokeemia uurimiseks!<br \/>N\u00fc\u00fcd on selle k\u00fctusevaru peaaegu otsas ja missioon peab l\u00f5ppema. Aeolus oli kavandatud tiirlema 320 km k\u00f5rgusel Maa pinnast, kuid n\u00fc\u00fcd langeb see iga p\u00e4ev aeglaselt umbes 1 km v\u00f5rra madalamale. Missiooni insenerid teadsid alati, et see hetk saabub, seega olid nad planeerinud, et Aeolus langeb loomulikul teel tagasi Maale ja p\u00f5leb atmosf\u00e4\u00e4ris \u00e4ra. Siiski on ESA kosmoselaeva insenerid otsustanud proovida l\u00e4bi viia esimest omalaadset abistatud atmosf\u00e4\u00e4ri sisenemist!<\/p>\n<p>Signaalide saatmine alates <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Technology\/Mission_control\/ESOC\" target=\"_blank\" rel=\"noopener\">ESA kosmoseoperatsioonide keskus Saksamaal<\/a>, kasutab lennujuhtimismeeskond Aeolusele j\u00e4\u00e4nud v\u00e4hest k\u00fctust satelliidi juhtimiseks selle Maale tagasip\u00f6\u00f6rdumise ajal. Suurem osa satelliidist p\u00f5leb \u00e4ra, kui see asub umbes 80 km k\u00f5rgusel Maa pinnast. Selleks ajaks on Aeolus paigutatud v\u00f5imalikult kaugele maismaast asuvale ookeanialale, nii et isegi kui m\u00f5ni satelliidi t\u00fckk peaks j\u00f5udma maapinnale, on v\u00e4ga ebat\u00f5en\u00e4oline, et see ohustaks inimesi.<br \/>ESA kosmoseprahi osakonna juhataja Tim Flohrer selgitab: <i>\u201cSee abistatud atmosf\u00e4\u00e4ri tagasip\u00f6\u00f6rdumise katse \u00fcletab 1990. aastate l\u00f5pus kavandatud ja projekteeritud missiooni ohutusn\u00f5udeid.
