Sen tarina alkaa jo 1960-luvulta, jolloin useat eurooppalaiset maat yhdistiv\u00e4t voimansa rakentaakseen uuden raketin avaruusajalle, nimelt\u00e4\u00e4n Europa! Hanke ep\u00e4onnistui, mutta vuonna 1975 Eurooppa yhdisti eri avaruusj\u00e4rjest\u00f6t muodostaakseen ESA:n, joka otti Europa-idean ja muokkasi siit\u00e4 Ariane-raketin. Ariane 1 -rakettien laukaisut alkoivat vuonna 1979, ja niit\u00e4 seurasivat uudet versiot aina Ariane 5:een asti.<\/p>\n<p>Tutkijat ja insin\u00f6\u00f6rit ovat kiireisi\u00e4 viimeistelem\u00e4ss\u00e4 ESA:n seuraavan sukupolven raketteja, <a href=\"https:\/\/www.esa.int\/Enabling_Support\/Space_Transportation\/Launch_vehicles\/Ariane_6\" target=\"_blank\" rel=\"noopener\">Ariane 6<\/a>! Niiden hinta on noin puolet Ariane 5:n hinnasta, mik\u00e4 merkitsee valtavaa s\u00e4\u00e4st\u00f6\u00e4. Ensimm\u00e4isen Ariane 6 -laukaisun toivotaan tapahtuvan ensi vuoden alussa!<\/p>\n<p><i>Mielenkiintoinen fakta: Ariane 5 -raketit eiv\u00e4t olleet pelk\u00e4st\u00e4\u00e4n luotettavia, vaan my\u00f6s eritt\u00e4in tehokkaita!
