NASA: Ancient Martian lake may have supported life

LOS ANGELES (AP) – NASA says the Curiosity rover has uncovered signs of an ancient freshwater lake on Mars that may have supported tiny organisms for tens of millions of years.

The lake near the Martian equator existed about 3.5 billion years ago. Scientists say it was neither salty nor acidic, and contained nutrients – a perfect spot to support microbes.

The findings were published online Monday in the journal Science and presented at the American Geophysical Union meeting in San Francisco.

Curiosity touched down near the Mars equator last year. Now that the $2.5 billion mission has accomplished a key goal – finding a habitable environment – the rover will look for organic compounds that are fundamental to all living things.

    Perhaps then, is there fossils in Mars, life in other planets? But, isn’t the emergence and maintenance of life a process of radical contingency ? That is, is a unique and unrepeatable past totally necessary? Or does life emerge through space like mushrooms in the field when some conditions are present? So, how many conditions are necessary: three, four, trillions, infinite? Only one, water or any sort of God? Is God the word that means infinite conditions? And, how did the life that emerge in a given conditions resist when switching to a different moment? How does life resist time itself, the effects of entropy? Anyway, is it possible for human beings to recognise a simpler life than their own brain only? On the other hand, is it possible to recognise a complex life than their brain, is this the extra-terrestrial life that some people are searching unsuccessfully? But, is there an origin of life or would it be as finding a cut in the material history of the universe, an infinite void that human language patches now? Is this the same cut between life and death? What would you and me be without this cut? Along these lines, a scientific-humanistic b-book, a public preview in Just another suggestion for leisure, far away from dogmas or axioms.
