Misiunea sa: testarea unor noi tehnologii, studierea v\u00e2nturilor din jurul planetei noastre \u0219i transmiterea de date c\u0103tre meteorologi, pentru a \u00eembun\u0103t\u0103\u021bi prognozele meteorologice la nivel global!<\/p>\n<\/div>\n<p>Aeolus a fost un satelit pionier, capabil s\u0103 m\u0103soare v\u00e2nturile globale din spa\u021biu cu ajutorul unui laser. Datele colectate ajungeau la meteorologi \u00een termen de trei ore, ceea ce l-a transformat \u00eentr-un instrument extraordinar pentru marile servicii de prognoz\u0103 meteorologic\u0103 din \u00eentreaga lume, inclusiv Centrul European pentru Prognoze Meteorologice pe Termen Mediu \u0219i Met Office din Marea Britanie. Aeolus a fost utilizat, de asemenea, pentru a afla mai multe despre coloanele vulcanice, pentru a \u00een\u021belege fenomenul prafului saharian \u0219i chiar pentru a studia biochimia oceanelor!<br \/>Acum, rezerva sa de combustibil este aproape epuizat\u0103, iar misiunea trebuie s\u0103 se \u00eencheie. Aeolus a fost proiectat s\u0103 orbiteze la 320 km deasupra suprafe\u021bei P\u0103m\u00e2ntului, dar acum coboar\u0103 \u00eencet cu aproximativ 1 km pe zi. Inginerii misiunii au \u0219tiut dintotdeauna c\u0103 acest moment va veni, a\u0219a c\u0103 au planificat ca Aeolus s\u0103 revin\u0103 \u00een mod natural pe P\u0103m\u00e2nt \u0219i s\u0103 se dezintegreze \u00een atmosfer\u0103. Cu toate acestea, inginerii spa\u021biali ai ESA au decis s\u0103 \u00eencerce o reintrare asistat\u0103, prima de acest gen!<\/p>\n<p>Transmiterea semnalelor de la <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Technology\/Mission_control\/ESOC\" target=\"_blank\" rel=\"noopener\">Centrul de opera\u021biuni spa\u021biale al ESA din Germania<\/a>, echipa de control al zborului va folosi pu\u021binul combustibil care i-a mai r\u0103mas satelitului Aeolus pentru a-l ghida \u00een timpul revenirii sale pe P\u0103m\u00e2nt. Cea mai mare parte a satelitului se va consuma la o altitudine de aproximativ 80 km deasupra suprafe\u021bei P\u0103m\u00e2ntului.
