Es sind wahre Geschichten aus Astronomie und Astrophysik, Geologie und Geowissenschaften.","poster":"https:\/\/astrogeo.de\/podlove\/image\/68747470733a2f2f617374726f67656f2e64652f77702d636f6e74656e742f75706c6f6164732f323032322f30322f4c6f676f5f71756164332d312d7363616c65642e6a7067\/500\/0\/0\/astrogeo-geschichten-aus-astronomie-und-geologie","link":"https:\/\/astrogeo.de"},"title":"Aluminium im Himmel: Wie Satelliten die Ozonschicht gef\u00e4hrden","subtitle":"Zwei unscheinbare Satelliten l\u00e4uteten 2018 eine neue \u00c4ra ein: Megakonstellationen aus tausenden Satelliten bieten Chancen, k\u00f6nnten aber die Ozonschicht gef\u00e4hrden. Karl erz\u00e4hlt von seiner Langzeitrecherche \u00fcber die Risiken f\u00fcr unsere Atmosph\u00e4re.","summary":"Am 22. Februar 2018 starten zwei unscheinbare Satelliten in eine Umlaufbahn: Sie sind weder besonders gro\u00df, noch auf andere Weise auff\u00e4llig. Aber diese zwei Satelliten, die den Namen Starlink tragen, l\u00e4uten einen Wandel im erdnahen Weltraum ein. Und der ist auch heute l\u00e4ngst noch nicht abgeschlossen. Wir befinden uns mitten im Zeitalter der Megakonstellationen - von tausenden Satelliten, die viele neue Anwendungen m\u00f6glich machen. Allerdings kommen diese Chancen der Raumfahrt zu einem hohen Preis.\r\nKarl erz\u00e4hlt in dieser Podcastfolge von seiner Langzeitrecherche \u00fcber die letzten sechs Jahre. Er wollte herausfinden, ob die Atmosph\u00e4re durch immer mehr startende Raketen und vor allem durch die stark wachsende Zahl vergl\u00fchender Satelliten besch\u00e4digt werden k\u00f6nnte. Wieder mal geht es um die Ozonschicht: Denn jeder vergl\u00fchende Satellit hinterl\u00e4sst Partikel aus Aluminium, die chemische Abbaureaktionen ansto\u00dfen k\u00f6nnten und dadurch den planetaren Schutzschicht gegen krebserregende UV-Strahlung der Sonne besch\u00e4digen.","publicationDate":"2024-09-05T00:00:00 +02:00 ","duration":"01:10:37 .813","poster":"https:\/\/astrogeo.de\/podlove\/image\/68747470733a2f2f617374726f67656f2e64652f77702d636f6e74656e742f75706c6f6164732f323032342f30382f61673039392e6a7067\/500\/0\/0\/aluminium-im-himmel-wie-satelliten-die-ozonschicht-gefaehrden","link":"https:\/\/astrogeo.de\/aluminium-im-himmel-wie-satelliten-die-ozonschicht-gefaehrden\/","chapters":[{"start":"00:00:00 .000","title":"Intro und Begr\u00fc\u00dfung","href":"","image":""},{"start":"00:01:33 .891","title":"Geschichte","href":"","image":""},{"start":"00:57:56 .494","title":"Diskussion: Altes menschliches Dilemma","href":"","image":""},{"start":"01:01:36 .194","title":"Quiz","href":"","image":""},{"start":"01:04:27 .704","title":"Diskussion: Wirtschaft und Regulation","href":"","image":""},{"start":"01:07:34 .920","title":"Unterst\u00fctzt uns.
