Le projet, en fait, a \u00e9t\u00e9 lanc\u00e9 depuis 2014 par les \u00c9mirats Arabes Unis pour, comme son nom l&rsquo;indique, partir \u00e0 l&rsquo;exploration de Mars. Une grande premi\u00e8re dans le monde arabe. Le d\u00e9collage de la sonde est pr\u00e9vu pour le 14 juillet 2020.<br \/>\nSelon les autorit\u00e9s \u00e9miraties, le lancement de la sonde devrait \u00eatre effectu\u00e9 \u00e0 partir de la petite \u00eele japonaise de Tanegashima. Selon l&rsquo;agence de presse Emirats News Agency, l&rsquo;objectif de la mission est de permettre \u00e0 la sonde en question d&rsquo;entrer dans l&rsquo;orbite de la plan\u00e8te Mars en f\u00e9vrier 2021. Une fois chose faite, la mission d&rsquo;observation devrait pouvoir commencer et elle durera 687 jours, ce qui repr\u00e9sente une ann\u00e9e martienne.<br \/>\nLa conqu\u00eate de l&rsquo;espace, comme nous le savons, comprend des enjeux politiques par excellence. Outre cet aspect, la mission des \u00c9mirats Arabes Unis comprend une dimension scientifique plut\u00f4t in\u00e9dite. En effet, alors que les pr\u00e9c\u00e9dentes missions \u00e9tudiaient la constitution tellurique de Mars, celle des \u00c9mirats Arabes Unis vise plut\u00f4t \u00e0 analyser l&rsquo;atmosph\u00e8re de l&rsquo;astre. Plus pr\u00e9cis\u00e9ment, il s&rsquo;agit de comprendre pourquoi l&rsquo;hydrog\u00e8ne et l&rsquo;oxyg\u00e8ne &#8211; les deux atomes formant l&rsquo;eau &#8211; ont disparu de la plan\u00e8te rouge.<br \/>\nDe fait, les scientifiques estiment que Mars poss\u00e8de des caract\u00e9ristiques similaires \u00e0 celles de notre Terre. <em>\u00ab\u00a0Elle poss\u00e9dait probablement des rivi\u00e8res, des oc\u00e9ans et une atmosph\u00e8re plus cl\u00e9mente il y a plusieurs milliards d&rsquo;ann\u00e9es\u00a0\u00bb<\/em>, estiment-ils.<br \/>\nL&rsquo;objectif serait donc de comprendre les raisons qui ont conduit la plan\u00e8te Mars \u00e0 devenir ce qu&rsquo;elle est aujourd&rsquo;hui : hostile \u00e0 la vie et sans la possibilit\u00e9 d&rsquo;une pr\u00e9sence de l&rsquo;eau.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mars Hope marquera certainement un tournant dans l&rsquo;Histoire de la conqu\u00eate spatiale.
