Jak minul\u00fd t\u00fdden informovala agentura Reuters<\/a>, rover detekoval podzemn\u00ed poz\u016fstatky d\u00e1vn\u00e9 \u0159\u00ed\u010dn\u00ed delty pomoc\u00ed georadaru.

Mars, stejn\u011b jako Zem\u011b, vznikl zhruba p\u0159ed 4,5\u00a0miliardy let, co\u017e znamen\u00e1, \u017ee tato delta existovala pom\u011brn\u011b brzy v\u00a0d\u011bjin\u00e1ch planety.<\/p>\n
