Un réservoir d’eau mystérieux découvert sur Mars

Une analyse plus approfondie des données de la sonde spatiale présente sur Mars, Odyssey, a montré des résultats incroyables que les scientifiques n’avaient pas prévus. La planète rouge cacherait de l’eau gelée là où il ne devrait pas y en avoir.


Une équipe de scientifiques américains de l’Université Johns-Hopkins aux États-Unis a découvert que sous la surface martienne, à proximité de son équateur, se trouve une grande quantité d’eau sous forme solide. Le groupe de chercheurs, dirigé par le scientifique Jack Wilson, a pu faire cette conclusion après avoir analysé les données de Mars Odyssey, la plus ancienne sonde spatiale de la NASA placée en orbite autour de Mars. Pourtant, la présence d’eau dans cette partie de la planète rouge est peu probable, vu son climat, relate la revue scientifique ScienceAlert.


Se trouvant à environ 4.000 kilomètres au-dessus de la surface martienne, la sonde Mars Odyssey n’est pas en mesure de définir la quantité précise d’eau glacée se trouvant sous le sol martien. Cependant, la sonde détecte des neutrons qui apparaissent suite à des collisions de rayons cosmiques avec de l’hydrogène. Cela a déjà permis de découvrir de la glace sur la planète rouge en 2002, mais elle se trouvait dans les zones polaires. Des scientifiques estimaient que sur l’équateur, la glace aurait dû disparaitre très vite au vu des conditions thermiques de la planète rouge.

Grâce à de nouvelles méthodes statistiques qui ont permis de reproduire des images de la nappe phréatique, il a été possible de découvrir que de la glace se trouvait également dans des zones plus chaudes de la planète, à proximité de son équateur.

Selon les scientifiques, il est possible d’expliquer ces résultats étranges par le fait qu’il y a plusieurs millions d’années, l’axe de Mars était incliné sous un autre angle, ce qui a provoqué l’accumulation d’une grande quantité de glace. Cependant, il est possible qu’il y ait quelque chose qui permette à l’eau glacée de résister à la fonte, estiment les chercheurs.
