The results indicated that even common bacteria were able to survive under the simulated conditions and that other microbes that have evolved to survive in extreme environments would fare even better.

Scientists have run an experiment to grow bacteria in conditions designed to simulate those on Mars.

Scientists have grown bacteria in a very low-atmospheric-pressure environment, similar to the surface of Mars.
