Organic Material Found on Mars

Over three decades after the Viking mission to Mars led scientists to believe there was no organic material on the red planet, new research says the results were misinterpreted. It turns out there was organic material there after all. But don’t jump to conclusions. This does not mean NASA is on the verge of discovering little green men. It simply means that there is a greater likelihood that some form of life exists, or has existed on Mars, and changes how scientists approach the search for it. "For decades NASA's mantra for Mars was 'follow the water' in the search for life, and we know today that water has been all over the planet," said one researcher. "Now the motto is 'follow the organics' in the search for life."
