Alors qu\u2019il s\u2019habitue progressivement \u00e0 la vie en impesanteur, Alex a pour l\u2019instant pass\u00e9 l\u2019essentiel de son temps \u00e0 d\u00e9couvrir son nouvel environnement, mettre en place son programme d\u2019exp\u00e9riences scientifiques, effectuer des prises de sang, faire de l\u2019exercice physique... mais aussi nettoyer les sanitaires.<\/p>\n<\/div>\n<p>Au matin du 30 mai, imm\u00e9diatement apr\u00e8s leur arriv\u00e9e, Alex et ses \u00e9quipiers Reid Wiseman et Maxim Suraev ont tenu une br\u00e8ve conf\u00e9rence pour leur famille et leurs amis rest\u00e9s sur Terre. Alex a laiss\u00e9 parler son enthousiasme en d\u00e9clarant : \u00ab C\u2019est g\u00e9nial, l\u00e0-haut ! \u00bb.<\/p>\n<p>L\u2019une des premi\u00e8res exp\u00e9riences d\u2019Alex a consist\u00e9 \u00e0 remplir un questionnaire sur ses maux de t\u00eate. De nombreux astronautes se plaignent en effet de violentes migraines en arrivant sur l\u2019ISS. La communaut\u00e9 scientifique aimerait aujourd\u2019hui comprendre quels astronautes en souffrent le plus, et \u00e0 quel moment.<\/p>\n<p>Comme pour de nombreuses autres exp\u00e9riences se d\u00e9roulant sur la Station, ce projet scientifique de l\u2019ESA portant sur les migraines spatiales va collecter des donn\u00e9es pendant plusieurs ann\u00e9es avec l\u2019intervention de nombreux astronautes.<\/p>\n<h2>Visite \u00e0 domicile<\/h2>\n<figure class=\"wp-block-image size-large\" data-width=\"1024\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2014\/06\/Expedition_portrait\" 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\/2014\/06\/expedition_portrait\/17880069-2-eng-GB\/Expedition_portrait.jpg\" alt=\"\"><\/figure>\n<p>Apr\u00e8s leur amarrage sur l\u2019ISS, le commandant Steve Swanson a convi\u00e9 Alex et son \u00e9quipier Reid \u00e0 visiter la Station (qui fait approximativement la taille d\u2019une grande maison de six chambres).
