Scientists identified signs of life on Mars
The region of Nili Fossae is a fracture on the surface of Mars
U.S. scientists have identified rocks that “may contain evidence of life on Mars”. The finding was in an area of Mars known as Nili Fossae.
According to the experts “this area of Mars is a vivid portrait of a region in Australia where there was buried and preserved evidence of ancient life on Earth.”
This discovery was published in Earth and Planetary Science Letters, and it was said that “the fossils found seem to be of 4 billion years ago.”
Although experts remarked that they “need to analyze this region of Mars in much more detail to see if they are really life signs or signs of a feature formed by geological processes.”
Scientists discovered since 2008 in the Nili Fossae, in a fractured surface of Mars, rocks containing carbonate minerals.
A team from the Institute for Search for Extraterrestrial Intelligence(SETI) in California, stated that “these Martian rocks were compared with those of the Pilbara region of Western Australia” and they believe that” the same hydrothermal process that preserved the markers of life in this region of the Earth may have occurred in the Nili Fossae region on Mars. “
Dr. Adrian Brown, head of the research said that “In the Pilbara region was preserved the oldest evidence of life on Earth.” “When we locate carbonate on Mars, this gave us a good indication that the Pilbara region was a vivid portrait of Nili Fossae and that we should look for signs of primitive life on this planet.”
The researchers found that “the rocks of Nili Fossae are very similar to rocks in the Pilbara, in terms of minerals they contain; this is an indication that in Nili Fossae remains of ancient life could be found.” The team hopes to look more closely at these rocks.
NASA’s next mission to Mars, which will be released next year, plans to visit Nili Fossae and unearth these potential evidence of life, but the U.S. agency recently said that “this rocky old site was too dangerous to put it in the robot’s orbit to explore it.”
The vehicle, called the Mars Science Laboratory will be the last to reach the Red Planet until 2018, and scientists expect the announcement of NASA on the place where it will be located. For SETI scientists would be the last chance to solve the mystery of whether life exists on Mars or not.
