Un groupe de scientifiques vient de choisir Oxia Planum comme meilleur site d'atterrissage pour notre rover d\u2019exploration martienne. Ce v\u00e9hicule robotique fera partie de la mission ExoMars 2018 de l\u2019Agence spatiale europ\u00e9enne, qui devrait atteindre la plan\u00e8te Mars en janvier 2019.<\/p>\n<\/div>\n

Oxia Planum est le site d'atterrissage pr\u00e9f\u00e9r\u00e9 des scientifiques pour deux raisons majeures. Tout d\u2019abord, il est plat. Cet aspect est tr\u00e8s important car, si le site comportait de gros rochers ou des pentes abruptes, le rover ExoMars pourrait s\u2019y retrouver bloqu\u00e9. D\u2019autre part, il semblerait qu\u2019Oxia Planum ait \u00e9t\u00e9 recouvert d\u2019eau dans un pass\u00e9 lointain. Si ce site a un jour abrit\u00e9 de l\u2019eau, il a potentiellement accueilli des formes de vie - peut-\u00eatre m\u00eame qu\u2019on en trouve toujours ! La recherche de la vie sur Mars est le principal objectif de mission du rover ExoMars.<\/p>\n

Si jamais nous devions trouver des cr\u00e9atures extraterrestres sur Mars, il ne s\u2019agirait pas de cr\u00e9atures capables de parler et de marcher comme nous, mais plut\u00f4t de formes de vie microscopiques. C\u2019est pourquoi leur recherche est compliqu\u00e9e ! Tout organisme vivant se cacherait probablement sous terre, \u00e0 l\u2019abri des conditions climatiques extr\u00eames qui r\u00e8gnent \u00e0 la surface de Mars. Les scientifiques de la mission s\u2019y sont pr\u00e9par\u00e9s, c\u2019est pourquoi ils ont \u00e9quip\u00e9 le rover ExoMars d\u2019une puissante foreuse capable d\u2019extraire des \u00e9chantillons jusqu\u2019\u00e0 deux m\u00e8tres sous la surface.<\/p>\n

D\u2019ici quelques ann\u00e9es, le rover ExoMars pourrait explorer Oxia Planum. Selon vous, que va-t-il y trouver ?<\/p>\n
