"We cannot yet say that Mars ever harbored life, but our findings further support the evidence that Mars was a habitable world around the time that life of Earth originated."
"The abundance of clay present in the Glen Torridon area of the crater suggests water was once present there, which is fundamental to the formation of carbon-based life as we know it."
NASA's Curiosity rover discovered seven organic compounds in Martian rock, five of which are new to Mars. The findings suggest the presence of a compound similar to DNA precursors. However, these organic compounds may have formed through nonbiological processes. Mars, formed 4.5 billion years ago, was once warmer and wetter, potentially supporting life. Curiosity's exploration of Gale Crater, with evidence of past water, indicates conditions suitable for carbon-based life. Researchers emphasize that while findings support Mars' habitability, no direct evidence of life has been found.
