Evidence of water on Mars (MARS) has been discovered by the American space agency NASA. After this, scientists examined the evidence of water found on the Red Planet. This investigation has been done by scientists from the California Institute of Technology (Caltech). In this investigation, it has been found that water was present on Mars 200 million years ago, because salt minerals that came with running water have been found there. Their traces are present in the form of white streaks on the surface of Mars which can be seen.
There have been many revelations from the data and photos from NASA's spacecraft Mars Reconnaissance Orbiter. Millions of years ago, there was a reservoir of rivers and ponds on Mars. Scientists believe that there must have been micro-life here as well. As the planet's atmosphere thinned, the water evaporated. Now only a desert area exists on Mars.
New information has emerged after this research. There was water on Mars until 100 years later. This suggests that water on Mars ended 200 million years ago. Caltech scientists have examined 15 years of data obtained from MRO. In this investigation, it has been found that water was present on Mars 200 to 250 million years ago. Scientists previously believed that water on Mars ended 300 million years ago. If compared to earlier, more watersheds for a billion years.
Salt streaks formed after the formation of vapor after the melting of icy water have been seen on the surface of Mars. For the first time, salt streaks have been seen on the planet Mars. These are indications that minerals are also present on the Red Planet. Now the question is how long the microorganisms must have been present on Mars. How long would life have existed in the water there?
The name of the scientist who did this study is Elaine Lisk and she is doing her Ph.D. at Caltech, Pasadena. Professor Bethany Allman assisted Elaine in this study. These researchers have taken help in studying data from MRO's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM). There are chloride salts in the craters present in the southern hemisphere of Mars. Apart from this, there are also highlands filled with clay.
