Life On Mars, Is It Possible?

Scientists seem to be excited about discovering bacteria living two miles beneath the Earth’s crust, able to adapt to not only extreme cold but also an oxygen-less environment.

(Mars Today) “The low temperature limit for life is particularly important since, in both the solar system and the Milky Way Galaxy, cold environments are much more common than hot environments,” said Neill Reid, an astronomer at the Space Telescope Science Institute and leader of the research team. “Our results show that the lowest temperatures at which these organisms can thrive fall within the temperature range experienced on present-day Mars, and could permit survival and growth, particularly beneath Mars’s surface. This could expand the realm of the habitable zone, the area in which life could exist, to colder Mars-like planets.”

Although it would be interesting to find life on Mars, the planet is not known to be friendly to life as its surface may be toxic, not to mention the lack of a magnetic field.

These organisms may provide another use however, as scientists may be able to insert their DNA into grains and plants, allowing colonists to grow food on the red planet. Of all the worlds that orbit the solar system, Mars provides the greatest opportunity for terraforming. Perhaps these microbes could provide a little assistance along the way.
