Pendant plus de 60 ans, ces \u00ab d\u00e9chets de l\u2019espace \u00bb se sont accumul\u00e9s au point d\u2019entourer notre plan\u00e8te et de provoquer de r\u00e9els probl\u00e8mes. Les d\u00e9bris spatiaux peuvent malheureusement entrer en collision avec des satellites actifs, au risque de les endommager ou de les d\u00e9truire - en cr\u00e9ant ainsi encore plus de d\u00e9bris ! Pour tenter d\u2019y rem\u00e9dier, les scientifiques et les chercheurs de l\u2019ESA ont d\u00e9velopp\u00e9 un moyen de nettoyer les d\u00e9bris spatiaux .<\/p>\n<\/div>\n<figure class=\"wp-block-image size-large\" data-width=\"720\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/08\/This_picture_shows_what_e.Deorbit_may_look_like_closing_in_on_a_disused_satellite\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2016\/08\/this_picture_shows_what_e.deorbit_may_look_like_closing_in_on_a_disused_satellite\/17912333-2-eng-GB\/This_picture_shows_what_e.Deorbit_may_look_like_closing_in_on_a_disused_satellite.png\" alt=\"This picture shows what e.Deorbit may look like, closing in on a disused satellite\"><figcaption>Cette image montre \u00e0 quoi pourrait ressembler e.Deorbit en s'approchant d'un satellite hors service<\/figcaption><\/figure>\n<p>Si tout se d\u00e9roule comme pr\u00e9vu, la mission e.Deorbit devrait \u00eatre lanc\u00e9e en 2023.
