Life on Mars???

Early NASA probes may have overlooked, even killed, Martian microbes
In a paper released on Sunday, a scientist theorized that thirty years ago when the Viking Space probes first visited the Red Planet, they may have stumbled upon alien microbes and inadvertantly killed them. During the 1970's when these missions took place, scientists found no signs of life, because they were looking for the wrong type. They were looking for Earth-like life. One Viking experiment seeking life on Mars poured water on soil. That would have essentially drowned hydrogen peroxide-based life, Schulze-Makuch said. A different experiment heated the soil to see if something would happen, but that would have baked Martian microbes, he said.
