    Mars rover finds signs of microbial life

    Nasa says its Mars rover Spirit has discovered "the best evidence yet" of a past habitable environment on the planet's surface.
    Spirit unearthed a patch of silica-rich soilSpirit has been exploring a plateau called Home Plate, where it discovered silica-rich soil in May.

    Researchers are now trying to determine what produced the patch of nearly pure silica - the main ingredient of window glass.

    They believe the deposits came from an ancient hot-spring environment or an environment called a fumarole, in which acidic steam rises through cracks.
    On Earth, both of these types of settings teem with microbial life, said rover chief scientist Steve Squyres.
    "Whichever of those conditions produced it, this concentration of silica is probably the most significant discovery by Spirit for revealing a habitable niche that existed on Mars in the past," he said.
    "The evidence is pointing most strongly toward fumarolic conditions, like you might see in Hawaii and in Iceland.

    That's a great discovery. From what I understand about Mars is next to Earth it's the most likely to support life in our solar system.

    It's a great discovery, but the existence of a fumarole isn't direct evidence of microbial life on Mars, is it?

    Mars gets pretty cold at night, you might want to reconsider your wardrobe.
