D\u00e9collage depuis <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Technology\/Rockets\/Europe_s_Spaceport\" target=\"_blank\" rel=\"noopener\">Le port spatial europ\u00e9en en Guyane fran\u00e7aise<\/a>, le vol de la fus\u00e9e a dur\u00e9 33 minutes. Sa mission consistait \u00e0 placer en orbite le satellite de communication exp\u00e9rimental \u00ab Heinrich Hertz \u00bb de l'agence a\u00e9rospatiale allemande DLR, ainsi que le satellite de communication fran\u00e7ais Syracuse 4b.\u00a0<\/p>\n<\/div>\n<p>Les fus\u00e9es Ariane 5 affichent un excellent bilan de r\u00e9ussite, et cette fois-ci n'a pas fait exception \u00e0 la r\u00e8gle puisque la mission s'est d\u00e9roul\u00e9e \u00e0 la perfection ! Les fus\u00e9es Ariane 5 ont \u00e9t\u00e9 utilis\u00e9es pour la premi\u00e8re fois en 1996 et ont, au total, effectu\u00e9 pas moins de 117 vols ! Elles ont mis en orbite d'importants satellites et sondes, notamment ceux de l'ESA <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/Comets_and_meteors\/Rosetta_makes_friends_with_a_comet\" target=\"_blank\" rel=\"noopener\">Rosetta, \u00e0 la poursuite des com\u00e8tes<\/a>, le <a href=\"https:\/\/www.esa.int\/kids\/en\/news\/The_James_Webb_Space_Telescope_will_investigate_the_origins_of_life_the_Universe_and_everything\" target=\"_blank\" rel=\"noopener\">T\u00e9lescope spatial James Webb<\/a>, et celui de l\u2019ESA <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Our_Universe\/JUICE\/Juice_mission_will_explore_Jupiter_and_its_icy_moons\" target=\"_blank\" rel=\"noopener\">Mission \u00ab Juice \u00bb vers Jupiter<\/a>. Les fus\u00e9es Ariane 5 ont \u00e9galement jou\u00e9 un r\u00f4le essentiel dans la participation de l'Europe au <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Life_in_Space\/Space_Stations\/The_International_Space_Station\" target=\"_blank\" rel=\"noopener\">Station spatiale internationale<\/a>, utilis\u00e9 pour fournir <a href=\"https:\/\/www.esa.int\/kids\/en\/learn\/Life_in_Space\/Space_Stations\/ESA_s_supply_ship\" target=\"_blank\" rel=\"noopener\">V\u00e9hicule de transfert automatis\u00e9<\/a> navire de ravitaillement.<\/p>\n<p>Les fus\u00e9es de la s\u00e9rie Ariane ont une histoire int\u00e9ressante. Leur histoire commence dans les ann\u00e9es 1960, lorsque plusieurs pays europ\u00e9ens ont uni leurs forces pour construire une nouvelle fus\u00e9e pour l'\u00e8re spatiale, baptis\u00e9e Europa ! Ce projet n'a pas abouti, mais en 1975, l'Europe a regroup\u00e9 diff\u00e9rentes organisations spatiales pour former l'ESA, qui a repris l'id\u00e9e d'Europa et l'a transform\u00e9e en Ariane. Les fus\u00e9es Ariane 1 ont commenc\u00e9 \u00e0 \u00eatre lanc\u00e9es en 1979, suivies de nouvelles versions jusqu'\u00e0 Ariane 5.<\/p>\n<p>Les scientifiques et les ing\u00e9nieurs s'affairent \u00e0 mettre la touche finale \u00e0 la prochaine g\u00e9n\u00e9ration de fus\u00e9es de l'ESA, <a href=\"https:\/\/www.esa.int\/Enabling_Support\/Space_Transportation\/Launch_vehicles\/Ariane_6\" target=\"_blank\" rel=\"noopener\">Ariane 6<\/a>! Leur co\u00fbt sera environ deux fois moins \u00e9lev\u00e9 que celui d'une Ariane 5, ce qui repr\u00e9sente une \u00e9conomie consid\u00e9rable. On esp\u00e8re que le premier lancement d'Ariane 6 aura lieu au d\u00e9but de l'ann\u00e9e prochaine !<\/p>\n<p><i>Fait int\u00e9ressant : les fus\u00e9es Ariane 5 n'\u00e9taient pas seulement fiables, mais aussi tr\u00e8s puissantes ! Elles pouvaient mettre en orbite deux gros satellites ou propulser des engins dans l'espace lointain.<\/i> \u00a0<\/p>\n<figure class=\"wp-block-embed is-type-video esa-video-hosted\"><a class=\"esa-video-hosted__link\" href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Videos\/2023\/07\/Ariane_5_bows_out_in_style\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"esa-video-hosted__poster\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/videos\/2023\/07\/ariane_5_bows_out_in_style\/24977768-1-eng-GB\/Ariane_5_bows_out_in_style.png\" alt=\"Ariane 5 bows out in style\" loading=\"lazy\" style=\"max-width:100%;height:auto\"><span class=\"esa-video-hosted__play\" aria-hidden=\"true\"><\/span><\/a><figcaption>Ariane 5 tire sa r\u00e9v\u00e9rence en beaut\u00e9<br \/><a class=\"esa-video-hosted__access\" href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Videos\/2023\/07\/Ariane_5_bows_out_in_style\" target=\"_blank\" rel=\"noopener\">Regarder la vid\u00e9o<\/a><\/figcaption><\/figure>","protected":false},"excerpt":{"rendered":"<p>5 July 2023 is a date to remember for space fans, as it was the last launch of an amazing ESA Ariane 5 rocket!
