Andreas a pass\u00e9 quatre nuits dans l\u2019habitat Aquarius, accompagn\u00e9 des astronautes de la NASA Joe Acaba et Kate Rubins ainsi que de l\u2019astronaute japonais Soichi Noguchi. Paxi (la mascotte du programme ESA Kids) s\u2019est temporairement absent\u00e9 de la capitale \u00e9cossaise \u00c9dimbourg, o\u00f9 avait lieu un congr\u00e8s scientifique, pour rendre visite \u00e0 son ami Andreas ! Comme vous pouvez le voir ci-dessus, Thomas a assur\u00e9 le r\u00f4le de responsable des communications.<\/p>\n<\/div>\n<p>Apprendre \u00e0 vivre et \u00e0 travailler dans l\u2019espace n\u2019est pas une mince affaire ! Des missions comme Seatest permettent aux astronautes de tester des proc\u00e9dures potentiellement utilisables \u00e0 bord de l'ISS, mais \u00e9galement de s\u2019entrainer \u00e0 20 m\u00e8tres sous l\u2019eau pour les sorties extrav\u00e9hiculaires dans l\u2019espace. Ces derniers apprennent \u00e9galement \u00e0 communiquer et \u00e0 travailler en \u00e9quipe dans un environnement international et multiculturel.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1024\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2013\/09\/Andreas_underwater2\" 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\/2013\/09\/andreas_underwater2\/17910085-2-eng-GB\/Andreas_underwater.jpg\" alt=\"Andreas underwater\"><figcaption>Andreas sous l'eau<\/figcaption><\/figure>\n<p>Chaque matin, deux membres de l\u2019\u00e9quipage se sont aventur\u00e9s \u00e0 l\u2019ext\u00e9rieur pour une sortie aquatique de trois heures, pendant que deux autres les surveillaient de l\u2019int\u00e9rieur d\u2019Aquarius. L\u2019apr\u00e8s-midi, les r\u00f4les \u00e9taient invers\u00e9s. Pendant ces exercices, les astronautes se sont entra\u00een\u00e9s \u00e0 se d\u00e9placer sur diff\u00e9rents terrains et ils ont \u00e9galement test\u00e9 de nouvelles m\u00e9thodes de r\u00e9colte d\u2019\u00e9chantillons de fonds marins. Les outils test\u00e9s comprenaient notamment une version modifi\u00e9e d\u2019une \u00ab pelle \u00e0 d\u00e9jections \u00bb et une foreuse permettant d\u2019effriter des rochers en toute s\u00e9curit\u00e9.<\/p>\n<p>Le troisi\u00e8me jour de leur mission, les astronautes ont ajust\u00e9 leur lestage pour recr\u00e9er la gravit\u00e9 de la Lune, o\u00f9 tout p\u00e8se six fois moins lourd que sur Terre. \u00ab Les sorties lunaires \u00e9taient les meilleures, \u00bb raconte Andreas. \u00ab C\u2019est une impression fantastique que de rebondir sur la surface. \u00bb<\/p>\n<p>\u00c0 l\u2019int\u00e9rieur d\u2019Aquarius, Andreas et ses coll\u00e8gues ont assembl\u00e9 et test\u00e9 un dispositif d\u2019exercice miniature contr\u00f4l\u00e9 par ordinateur.
