Mars Reconnaissance Orbiter had captured the 'dark finger-style' marks on Mars in 2011. And now NASA confirms the marks can be the imprint of the water flow on the surface of the Red Planet. The recent confirmation has given scientists a big hope to discover the source of water to secure the existence of organic life on the Mars. Nasa announced the marks of water flow as a 'major scientific discovery.'
The dazzling photographs of the water signs on the Red Planet are also revealed. Take a look.
The marks of the seasonal flow is the significant evidence to confirm the possibility of the organic life on the Mars.
You can easily spot the difference between the two pictures. The second picture contains the marks of the seasonal flow of water. The watermarks appear in the several locations of the planet in the temperature above minus 23 Celsius. NASA says the marks disappear at colder times.
During the Press Conference by NASA in Washington, John Grunsfeld (astronaut and associate administrator, NASA's Science Mission Directorate) said: 'Our quest on Mars has been to 'follow the water,' in our search for life in the universe, and now we have convincing science that validates what we've long suspected.'
Mars had the oceans for more than 1.5 billion years, and they were larger than the Artic Ocean. But by now, it has lost 87% of the water it had. Dr Michael Mumma (co-author of the study and Senior Scientist) said, 'Curiosity shows it was wet for 1.5 billion years, already much longer than the period of time needed for life to develop on Earth. And now we see that Mars must have been wet for a period even longer.'
Lujendra Ojha is credited with the accidental discovery of the watermarks on the surface of the alien world after studying the images taken by Reconnaissance Orbiter in 2011. Ojha said: 'That is really the key here. The fact these salts are hydrated means there is presence of molecular water in their structure.'
NASA states: 'Our findings strongly support the hypothesis that recurring slope lineae form as a result of contemporary water activity on Mars.'
Red marks are the locations where salts have been detected.
