Contour, seen on Mars, is often made of rain water; Scientists say that the angle of the valleys’ branches on the red planet was found in the dry landscape on the same planet. The surface of Mars gives bearings to the impressions of structures that resemble fluvial steam networks on Earth.
Scientists believe that to feed the flow of water on the Red Planet, there should be enough water once, putting its way into the soil.
However, for years, scientists are arguing on this source from which this water should originate. A research established in Science Advance indicates that, the branch structure of the East River Network on Mars has brought parallels with terrestrial arid landscapes. Through data from all mapped river valleys on Mars, researchers have concluded that the faces visible today should be made from the surface stream of rain water.
Consequently, the effects of ground water seepage from soil can be excluded as a major process to shape these features. Distribution of angles of the branches of the valleys on Mars is found in the dry landscape on Earth. This implies that there should be a similar hydroelectric environment with long periods of heavy rain on Mars and it can run fast on the surface shaping the rainwater valley network.
River valleys develop in arid areas on Earth. Like, in Arizona, researchers uses same valley network pattern in a storyline where astronauts are trained for upcoming Mars mission. Valleys in the fork of dry areas at a narrow angle.
Angle of branches on Mars is comparatively low. Therefore, Seybold controls the impact of the size of the groundwater in the form of the main channel on Mars. Found in the form of rivers that are formed by the emerging groundwater for example in Florida, for example, there are very wide branches angle between the two tributaries, and the narrow angle of the rivers in arid regions does not match Accounts. The terrestrial dry landscape rises relatively short period from 3.68 to 3.8 billion years ago on Tuesday.
In that period, the environment on Mars can be quite dense compared to today. “Recent research shows that there would be much more water on Mars than pre-imagined,” said Professor Hansjorg Seybold, ETH Zurich.
One hypothesis suggests that at that time there was an ocean covered in the northern third sea of Mars. The water was evaporated, surrounded by high volcanoes of highlands in the south of the ocean and there was heavy rain. The big question is that the water has disappeared over time. “It is likely that most of these have evaporated into space, but it can still be found in areas around Mars. This is a question for future space missions,” Seybold said.
