NASA: The search for life on Mars continues, as NASA finds what may be “flowing rivulets of water” on the red planet, said scientists on September 28, 2015.
NASA’s director of planetary science, Jim Green, said that Mars is not as dry and arid as expected in the past.
This is not the first time that scientists have found traces of water on the red planet. Back in 2008, it was confirmed that there is presence of frozen water on Mars.
The latest news of finding water comes after the instruments of Mars Reconnaissance Orbiter gave the strongest evidence for the same. This is a big development as water was been found in liquid form down slopes of Mars.
Given that NASA and many other organizations are looking for life on Mars, the presence of liquid water may be seen as a big move. It also gives the impression of possible microscopic life forms on the planet.
The scientists also added that the found rivulets are around 12 to 15 feet wide and 300 feet long. Apparently, the rivulets consist of wet soil and not standing water.
Salts like magnesium perchlorate, sodium perchlorate and magnesium chlorate are believed to be present in the “water”, which prevents water from freezing at extreme low temperatures.
This theory of ‘water containing salts’ may be the reason for presence of water in liquid form, as the temperature on the red planet is minus 85 degrees Fahrenheit on an average, said a report on Journal Now.
While the presence of water may be a big clue in search of life on Mars, it will also help astronauts in their survival and stay, given that NASA is planning to send humans to the planet soon.
NASA’s Mars exploration program’s scientist, Michael Meyer, said that the only way to find the presence of life on Mars is to collect and analyze rocks and soil.
