Le rover Curiosity a immortalis\u00e9 une concr\u00e9tion min\u00e9rale en forme de fleur sur la surface de Mars. Large d\u2019\u00e0 peine un centim\u00e8tre, cette concr\u00e9tion est \u00ab\u00a0\u00e9rod\u00e9e par une roche s\u00e9dimentaire qui a \u00e9t\u00e9 ciment\u00e9e par une eau souterraine riche en min\u00e9raux\u00a0\u00bb, indique le compte Twitter du rover.<\/p>\n

Le rover s\u2019est servi de sa cam\u00e9ra Mars Hand Lens Imager (MAHLI) \u00e0 l’extr\u00e9mit\u00e9 de son bras robotique pour faire deux \u00e0 huit images qui ont permis de r\u00e9aliser une vid\u00e9o 3D.<\/p>\n

La concr\u00e9tion est constitu\u00e9e de sels appel\u00e9s sulfates, pr\u00e9cise sur Twitter Abigail Fraeman, scientifique adjointe du projet Curiosity. Selon Futura Sciences, cette formation min\u00e9rale pourrait \u00eatre l\u2019analogue de la rose des sables, propre aux d\u00e9serts.<\/p>\n

Le rover Curiosity partage tr\u00e8s r\u00e9guli\u00e8rement des photos de Mars avec la Terre. En juillet 2020, la cha\u00eene YouTube ElderFox Documentaries a pu reconstituer des images ultra-haute d\u00e9finition de la plan\u00e8te rouge \u00e0 partir de prises de vues dans le crat\u00e8re de Gale, o\u00f9 le rover a atterri en 2012.<\/p>\n

Les selfies que prend Curiosity permettent \u00e9galement de constater l\u2019\u00e9tat du robot, en mission depuis 10 ans, et qui a largement d\u00e9pass\u00e9 son esp\u00e9rance de vie.<\/p>\n

En f\u00e9vrier 2021, le rover Perserverance, successeur de Curiosity, s\u2019est \u00e0 son tour pos\u00e9 sur Mars, apr\u00e8s un voyage de 203 jours et de 472 millions de kilom\u00e8tres. Il a pour principal objectif de rechercher des signes de vie microbienne sur place.<\/p>\n
