Africa-Press – Djibouti. <\/strong><\/span>Un sol blanc a\u0300 perte de vue, un halo vert et trois points lumineux dans le ciel: le Soleil, la Terre et Ve\u0301nus. Voici a\u0300 quoi ressemble un coucher de soleil sur la Lune.<\/p>\n

La Nasa et l’entreprise spatiale ame\u0301ricaine Firefly Aerospace ont re\u0301ve\u0301le\u0301 mardi les premie\u0300res images haute de\u0301finition d’un coucher de soleil lunaire, prises par un robot s’e\u0301tant pose\u0301 de\u0301but mars a\u0300 la surface de l’astre.<\/p>\n

Des cliche\u0301s qui pourraient notamment permettre aux scientifiques d’e\u0301lucider enfin le myste\u0300re de cette lueur a\u0300 la surface de la Lune, observe\u0301e pour la premie\u0300re fois sur le satellite de la Terre dans les anne\u0301es 1960.<\/p>\n

\u00ab\u00a0Nous prenons le temps de demander a\u0300 des spe\u0301cialistes scientifiques d’examiner toutes les images\u00a0\u00bb, a de\u0301clare\u0301 Joel Kearns, un responsable de la Nasa, lors d’une confe\u0301rence de presse mardi.<\/p>\n

Ce phe\u0301nome\u0300ne a e\u0301te\u0301 observe\u0301 pour la premie\u0300re fois dans les anne\u0301es 1960 par des sondes de la Nasa, et plus tard par des astronautes. L’une des explications envisage\u0301es est qu’il soit du\u0302 a\u0300 la le\u0301vitation de particules de poussie\u0300re lunaire charge\u0301es e\u0301lectriquement par les rayonnements du Soleil.<\/p>\n

Les cliche\u0301s pre\u0301sente\u0301s cette semaine ont e\u0301te\u0301 pris par Blue Ghost, un robot de\u0301veloppe\u0301 par l’entreprise Firefly Aerospace pour le compte de la Nasa. Arrive\u0301 de\u0301but mars sur la Lune, il a re\u0301alise\u0301 pendant deux semaines de multiples expe\u0301riences scientifiques et a pris d’autres cliche\u0301s, notamment d’une e\u0301clipse lunaire.<\/p>\n

\u00ab\u00a0Les images sont magnifiques, elles sont vraiment esthe\u0301tiques\u00a0\u00bb, a salue\u0301 M. Kearns.<\/p>\n

La Nasa a choisi il y a plusieurs anne\u0301es dans un objectif de baisse des cou\u0302ts de charger le secteur prive\u0301 de l’envoi de mate\u0301riel et de technologies sur la Lune, destine\u0301s a\u0300 pre\u0301parer le terrain pour de futures missions humaines.<\/p>\n

La mission de Firefly Aerospace, qui s’inscrit dans ce cadre, a e\u0301te\u0301 un succe\u0300s \u00ab\u00a0a\u0300 100%\u00a0\u00bb, a assure\u0301 mardi Jason Kim, son directeur ge\u0301ne\u0301ral, e\u0301voquant \u00ab\u00a0un tournant dans l’histoire\u00a0\u00bb.<\/p>\n

La socie\u0301te\u0301 texane a en effet re\u0301ussi de\u0300s sa premie\u0300re tentative a\u0300 faire alunir son robot sur la surface lunaire, une prouesse technique. Avant qu’une autre entreprise prive\u0301e ame\u0301ricaine n’y parvienne en fe\u0301vrier 2024, seule une poigne\u0301e de pays, a\u0300 commencer par l’Union sovie\u0301tique en 1966, y e\u0301taient parvenus.<\/p>\n
