Mars had seas and rivers during billions of years more
Mars had great seas and rivers during billions of years more than until now it was believed, according to the results of a new interpretation of images obtained by the Mars Reconnaissance Orbiter sounding. The existence of great masses of liquid water during so many million years increases the possibility that at some time there was life in the Red Planet.
The analysis of the photographies, obtained from the Martian orbit, has allowed to identify a series of elements in the land that formed by the action of the liquid water.
The studied area is the plains that are next to the Marineris valley, a zone that formed during the era Hespérica, does between 3000 and 3700 million years, practically thousand years subsequent to the era Noeica, that until now thought that it had been in which was water in liquid state.
“It has been a very great surprise to find these extensive fluvial land systems formed in the era Hespérica. Everybody thought that by then Mars already was much more dry”, indicates Catherine Weitz, of the equipment of investigation of the Institute of Planetary Sciences of Tucson (EE.UU.) that has realised the discovery.
