Microbes ‘could survive on Mars’ BBC

Microbes may be able to survive on Mars according to new simulations of the Martian environment. Researchers used a device called the Andromeda Chamber to simulate Martian conditions. They discovered that microorganisms called methanogens could grow at low pressures. They say their findings imply that life could have existed on the Red Planet in the past, present, or at some point in the future.
