Scientists have revisited the idea that organic molecules could be present in the soil on Mars.
Tests conducted in the Atacama Desert in Chile intended to be as close to the conditions on Mars as possible have revealed that the same tests conducted by the Viking lander yielded similar results when conducted there and that chemical reactions in the soil due to the test effectively killed off all the organic compounds.
Carbon-rich organic molecules, which serve as the building blocks of life, may be present on Mars after all, say scientists - challenging a widely-held notion of the Red Planet as barren.
