Africa-Press – Burkina Faso. <\/strong><\/span>Un petit morceau de roche pris sur Mars est \u00abmaintenant enferm\u00e9 dans un tube \u00e0 \u00e9chantillon en titane herm\u00e9tique, ce qui le rend disponible pour une r\u00e9cup\u00e9ration future\u00bb.<\/p>\n

Le rover Perseverance de la NASA a r\u00e9ussi \u00e0 collecter le premier \u00e9chantillon de roche sur Mars, a annonc\u00e9 le 6 septembre l’agence spatiale am\u00e9ricaine. Le petit morceau est \u00abmaintenant enferm\u00e9 dans un tube \u00e0 \u00e9chantillon en titane herm\u00e9tique, ce qui le rend disponible pour une r\u00e9cup\u00e9ration future\u00bb.<\/p>\n

Dans le cadre de leurs objectifs, la NASA et l’ESA (Agence spatiale europ\u00e9enne) pr\u00e9voient une s\u00e9rie de futures missions pour ramener ces \u00e9chantillons sur Terre pour une \u00e9tude plus approfondie, indique la m\u00eame source qui pr\u00e9cise que ces \u00e9chantillons seraient le premier ensemble de mat\u00e9riaux scientifiquement identifi\u00e9s et s\u00e9lectionn\u00e9s renvoy\u00e9s sur la plan\u00e8te Terre depuis une autre.<\/p>\n

En plus d’identifier et de collecter des \u00e9chantillons de roche et de r\u00e9golithe (roche bris\u00e9e et poussi\u00e8re) tout en recherchant des signes de vie microscopique ancienne, la mission de Pers\u00e9v\u00e9rance comprend l’\u00e9tude de la r\u00e9gion de Jezero pour comprendre la g\u00e9ologie et l’habitabilit\u00e9 ancienne de la r\u00e9gion, ainsi que pour comprendre le climat du pass\u00e9.<\/p>\n

Perseverance est le cinqui\u00e8me et le plus sophistiqu\u00e9 rover que la NASA a envoy\u00e9 jusqu\u2019\u00e0 pr\u00e9sent sur Mars. Il s’appuie sur les le\u00e7ons tir\u00e9es d’autres robots envoy\u00e9s sur la plan\u00e8te rouge. L’astromobile de la taille d’un v\u00e9hicule mesure environ 3 m\u00e8tres de long, 2,7 m\u00e8tres de large, 2,2 m\u00e8tres de haut et p\u00e8se 1025 kilogrammes.<\/p>\n

Arriv\u00e9 sur Mars en f\u00e9vrier dernier, il recherche des signes de vie microbienne ancienne, \u00e9tudie la g\u00e9ologie et le climat de la plan\u00e8te, et collecte des \u00e9chantillons de roches et de s\u00e9diments soigneusement s\u00e9lectionn\u00e9s en vue d’un \u00e9ventuel retour sur Terre en 2026 avec l’ambition d’ouvrir la voie \u00e0 une future exploration humaine.<\/p>\n
