Depuis son lancement en 2004, Rosetta a parcouru quasiment 8 milliards de kilom\u00e8tres. Elle a survol\u00e9 trois fois la Terre et une fois la plan\u00e8te Mars, et elle a crois\u00e9 deux ast\u00e9ro\u00efdes pendant sa mission \u00e0 travers l\u2019espace ! Mais ce n\u2019est pas tout : Rosetta a \u00e9t\u00e9 le premier v\u00e9hicule spatial \u00e0 \u00e9voluer en orbite autour d\u2019une com\u00e8te (67P\/Churyumov-Gerasimenko) et le premier \u00e0 y envoyer un atterrisseur, baptis\u00e9 Philae, en novembre 2014.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"ESA\/ATG medialab\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/10\/This_picture_shows_what_it_would_have_looked_like_moments_before_Rosetta_hit_the_comet\" 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\/10\/this_picture_shows_what_it_would_have_looked_like_moments_before_rosetta_hit_the_comet\/17880772-2-eng-GB\/This_picture_shows_what_it_would_have_looked_like_moments_before_Rosetta_hit_the_comet.jpg\" alt=\"This picture shows what it would have looked like moments before Rosetta hit the comet\"><figcaption>Cette image montre \u00e0 quoi cela aurait ressembl\u00e9 quelques instants avant que Rosetta ne percute la com\u00e8te<\/figcaption><\/figure>\n<p>La d\u00e9cision de mettre un terme \u00e0 la mission Rosetta n\u2019a pas \u00e9t\u00e9 facile pour les \u00e9quipes de l\u2019ESA, mais la sonde spatiale \u00e9voluait d\u00e9sormais aux confins de notre syst\u00e8me solaire, en continuant de s\u2019\u00e9loigner \u00e0 chaque seconde.
