Earth Microbes Not Likely to Contaminate Mars, Scientists Say

[mickw]

Scientists have long been concerned with the possibility that their search for any signs of life on Mars could be thrown off-course by wayward microorganisms from Earth that hitch a ride to the red planet on man-made spacecraft. But a new study suggests that fear may be less likely than researchers once thought.

While some bacteria could potentially survive the harsh trip through space, Mars atmospheric entry and landing, they would most likely die soon after landing on Mars because of the planet's harsh atmosphere, the study found.

Ultimately it is unlikely such microorganisms will be able to replicate once on the Martian surface, the research suggests.
