Carbon on the surface of Mars.The NASA’s rover Curiosity looking around for the chemical ingredients and environment for microbial life on Mars,has transmitted material indicating there could be carbon on its surface.
But scientists are not sure if this carbon which facilitated growth of life on Earth has done the same on Mars,says a byline story by Irene Klotz under title – NASA’s Mars rover finds traces of carbon – quoting scientists.
“Just finding carbon somewhere doesn’t mean that it has anything to do with life, or the finding of a habitable environment,” the same story adds saying lead scientist John Grotzinger, with the California Institute of Technology, told reporters at the American Geophysical Union conference in San Francisco.
Notably,carbon without any water can not make a habitable environment.”Even with carbon and water, life needs other chemicals, such as sulfur, oxygen, phosphorous and nitrogen, to form and evolve”,states the same article.
It further states:”It’s not unexpected that this sand pile would not be rich in organics. It’s been exposed to the harsh Martian environment,” added planetary scientist Paul Mahaffy, with NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
It’s really going to be an exciting hunt over the course of this mission to find early environments that might be protected from this surface Mars environment and see what we can add to the carbon story,”the article quotes Mahaffy as saying.
“The rover, which in August touched down on the floor of a 93-mile wide (150-km) impact crater near the Martian equator, has already turned up evidence that its landing site was once covered in water.”
