Cette mission comporte deux \u00e9l\u00e9ments distincts : une sonde spatiale baptis\u00e9e Trace Gas Orbiter (TGO), qui restera dans l\u2019espace autour de Mars, et un robot appel\u00e9 Schiaparelli, qui va atterrir \u00e0 la surface de la plan\u00e8te.<\/p>\n<\/div>\n<p>La sonde TGO va \u00e9tudier les gaz de l\u2019atmosph\u00e8re martienne afin de d\u00e9terminer si leur source est d\u2019origine g\u00e9ologique ou biologique. Cela devrait nous aider \u00e0 savoir si la Plan\u00e8te rouge a d\u00e9j\u00e0 abrit\u00e9 des formes de vie ! Le 16 octobre prochain, TGO va se s\u00e9parer du robot Schiaparelli, qui effectuera ensuite un voyage de trois jours en direction de Mars. Schiaparelli entrera dans la fine atmosph\u00e8re martienne le 19 octobre, avant d\u2019entamer une descente mouvement\u00e9e de six minutes jusqu\u2019\u00e0 la surface de la plan\u00e8te. Si tout se passe bien, Schiaparelli devrait atterrir dans la r\u00e9gion de Meridiani Planum.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2000\" data-credit=\"ESA\/ATG medialab\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2016\/10\/The_Schiaparelli_lander_will_look_like_this_once_it_is_on_the_surface_of_Mars\" 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\/the_schiaparelli_lander_will_look_like_this_once_it_is_on_the_surface_of_mars\/18246069-2-eng-GB\/The_Schiaparelli_lander_will_look_like_this_once_it_is_on_the_surface_of_Mars.jpg\" alt=\"The Schiaparelli lander will look like this once it is on the surface of Mars\"><figcaption>Voici \u00e0 quoi ressemblera l'atterrisseur Schiaparelli une fois pos\u00e9 \u00e0 la surface de Mars<\/figcaption><\/figure>\n<p>Le robot Schiaparelli va tester des technologies et des \u00e9quipements qui pourraient \u00eatre requis lors de futures missions d\u2019atterrissage sur Mars.
