The existence of a toxic chemical discovered in the Martian soil could reduce the chances of life being found on the planet

Even though there appears to be traces of water on the Red Planet of Mars, a toxic chemical found in the soil located near the Martian north pole has put a damper on the possibility of life on the planet.

The perchlorate chemical, often times used in solid rocket fuel, is an odd discovery, forcing researchers to try and check to ensure the chemical didn't get taken to Mars from Earth.  Several more soil tests in the area will be conducted by researchers, although they are not sure how the chemical develops or the exact amount of it in the soil.

"While we have not completed our process on these soil samples, we have very interesting intermediate results," said Peter Smith, principal investigator from the project.

The Microscopy, Electrochemistry and Conductivity Analyzer aboard the Phoenix recently tested two different soil samples collected at the north pole.  MECA previously painted a rather optimistic picture about the possibility of life on the Red Planet, which became more believable after evidence of ice crumbs found on the planet.

NASA decided to use MECA on Mars because it is able to test the acidity and presence of certain chemicals, salts and minerals in all collected soil samples.

Researchers believe it's still possible that life has existed on the planet, and believe it's possible life could be found in underground aquifers that are able to help reduce exposure to the toxic soil.  

Alongside MECA, NASA also is using the Thermal and Evolved-Gas Analyzer (TEGA) to help try and find evidence of organic chemicals and the possibility of life on the Mars' surface.

Brown University researcher John Mustard, who doesn't have a hand in the project, said that all researchers should reserve judgment regarding the possibility of life on the Red Planet because of the existence of perchlorate.

I disagree entirely...

#1 - Life as we know it is limited to tests and observations on one out of 100's of trillions (actually its a much higher # than even that!) of planets that exist in the universe.

#2 - Just because there is certain chems in the soil in one location, doesnt mean its in every region of the planet. Go check soil samples in Antarctica, Africa, Australia, and North America... You will find differences in each.

Not only that but there are many toxic chemicals and terrible conditions on earth in which bacteria grow, from radio active, to high salt, high temperature, low temperature it simply does not matter the bacteria have evolved ways to deal with it. Either buy converting harmfull substance to inert ones or keeping them out or any number of things. One thing is true though on earth where ever there is energy to be had we can find life that has figured out how to exploit it.
