Dens opgave er at afpr\u00f8ve nye teknologier, unders\u00f8ge vindforholdene omkring vores planet og sende data til meteorologer for dermed at forbedre vejrudsigterne for hele kloden!<\/p>\n<\/div>\n<p>Aeolus var en banebrydende satellit, der kunne m\u00e5le globale vindforhold fra rummet ved hj\u00e6lp af en laser. De indsamlede data kunne n\u00e5 frem til vejrprognoserne inden for tre timer, hvilket gjorde den til et fremragende redskab for store vejrprognosetjenester over hele verden, herunder Det Europ\u00e6iske Center for Mellemlangtidsvejrprognoser og det britiske Met Office. Aeolus er ogs\u00e5 blevet brugt til at indsamle viden om vulkanske r\u00f8gs\u00f8jler, forst\u00e5 st\u00f8v fra Sahara og endda studere havets biokemi!<br \/>Nu er br\u00e6ndstofforsyningen n\u00e6sten opbrugt, og missionen m\u00e5 afsluttes. Aeolus var konstrueret til at kredse 320 km over Jordens overflade, men den falder nu langsomt med omkring 1 km hver dag. Missionsingeni\u00f8rerne har altid vidst, at dette \u00f8jeblik ville komme, og de havde derfor planlagt, at Aeolus naturligt skulle falde tilbage til Jorden og br\u00e6nde op i atmosf\u00e6ren. ESA\u2019s rumfart\u00f8jsingeni\u00f8rer har imidlertid besluttet at fors\u00f8ge sig med en assisteret genindtr\u00e6den \u2013 den f\u00f8rste af sin art!<\/p>\n<p>Afsendelse af signaler fra <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Technology\/Mission_control\/ESOC\" target=\"_blank\" rel=\"noopener\">ESA\u2019s rumoperationscenter i Tyskland<\/a>, vil flyvekontrolteamet bruge det lille br\u00e6ndstof, Aeolus har tilbage, til at styre satellitten under dens tilbagevenden til Jorden. St\u00f8rstedelen af satellitten vil br\u00e6nde op, n\u00e5r den befinder sig ca. 80 km over Jordens overflade. P\u00e5 det tidspunkt vil Aeolus v\u00e6re placeret over et havomr\u00e5de s\u00e5 langt v\u00e6k fra land som muligt, s\u00e5 hvis der skulle v\u00e6re dele af satellitten, der n\u00e5r ned til overfladen, er det meget usandsynligt, at nogen mennesker vil v\u00e6re i fare.<br \/>Tim Flohrer, leder af ESA\u2019s kontor for rumskrot, forklarer: <i>\u201cDette fors\u00f8g p\u00e5 assisteret genindtr\u00e6den g\u00e5r langt ud over sikkerhedsbestemmelserne for missionen, som blev planlagt og udformet i slutningen af 1990\u201derne. Hvis alt g\u00e5r efter planen, vil Aeolus leve op til de g\u00e6ldende sikkerhedsbestemmelser for missioner, der udformes i dag.\u00ab<\/i><br \/>Hvis det lykkes, kunne denne metode til assisteret genindtr\u00e6den i atmosf\u00e6ren bruges til at hj\u00e6lpe andre \u00e6ldre satellitter med at tr\u00e6nge ind i Jordens atmosf\u00e6re og dermed afslutte deres missioner p\u00e5 den sikreste m\u00e5de!<\/p>\n<p><i>Interessant faktum: Fem \u00e5r er langt l\u00e6ngere, end det var planlagt, at Aeolus skulle v\u00e6re i kredsl\u00f8b.
