Water on Mars was discovered a long time, and, moreover, its stock only in the polar ice caps were so huge that they would be enough for the formation of the oceans of mammoth proportions and a large depth.

In these manipulations NASA considered the biggest achievement since the landing apparatus on the surface of Mars, but in March in some rock samples obtained rover had found traces of hydrated calcium sulfate - in fact it is gypsum, which means rock in contact with the water.
One of their pens - neutron scanner DAN (Dynamic Albedo of Neutrons), which is made in Russia - the rover Curiosity poked the surface of the Red Planet, and found traces of ground water at a depth of 60 cm Moreover, recent data from the satellite MRO showed that water in the Mars has existed for more than 3 billion years ago in a favorable period for the origin of life.
