Meteorites on Mars Suggest Super Drought Wiped Out Alien Life
Many believe that Mars is not as dead and dry as it is today. This is the reason why a lot of theories about how Mars 'died' are being presented; one of which is the potential role played by meteorites in the long lasting drought on Mars.
This also suggests that there could be some form of alien life form thriving on the red planet before meteorites initiated super drought on Mars obliterating any living organism on the planet. This finding was presented after researchers were able to analyze the metallic meteorite recently spotted on the surface of Mars.
Last Oct. 30, NASA's Mars Curiosity Rover captured an image of an odd looking rock on the Martian surface; turned out the rock was a part of a meteorite. Apparently, finding these space rocks are nothing unusual on the red planet and it is a good learning ground for the scientists and researchers.
"On Mars, iron meteorites dominate the small number of meteorites that have been found. Part of the explanation could come from the resistance of iron meteorites to erosion processes on Mars," a NASA official said in a statement.
Researchers suggest that iron materials have a tendency to rust when it collide with water and oxygen. On Mars, it will take a maximum of 10,000 times longer to reach the lever of rust formations compared to the driest part of the Earth. But the Martian meteorites lack rust that means the surface of the red planet is extremely dry.
Experts say that Mars has already been experiencing super-drought for about million years. Technically, a super drought has the capability to wipe out any life form or any living organism. But to start with, Mars has no liquid water that makes finding any form of alien life very difficult, if not impossible.
The University of Stirling researchers in Scotland conducted the study. The study believes that in order to find life, the existence of water is vital. And although the planet is in super drought condition today, they believe that water once flowed on the red planet.
"Evidence shows that more than three billion years ago Mars was wet and habitable," Dr. Christian Schröder, the study team leader said in a statement. "However, this latest research reaffirms just how dry the environment is today," Schröder added.
