Scientists have found that certain types of microbes living in the world, can easily live in Mars, so the units that are already in large numbers in recent years, landed on the Red Planet's surface, could easily to bring himself to Mars samples of terrestrial biology. Accordingly, if in the future the same device detects Curiosity Mars microbes can not be a 100% chance to say that they are the true inhabitants of the planet. However, most of the scientists also said that if the earthly germs and can physically exist on Mars it does not mean that they can live there for a long period of time - radiation, the total lack of humidity and nutrients of organic matter will do the job and germs can not survive.
A joint team of scientists from Russia and the United States has demonstrated that microbes living in natural conditions in Kolyma, could survive on Mars. According to scientists, if the data microbes survive on Mars in reality or not, this is still an open question, but the monitoring of these organisms can certainly help prepare for future missions to Mars.
