Processing of spacecraft before sending them to Mars does not make them sterile, respectively, terrestrial life is recorded on the planet, says Boris Shustov, scientific director of the Institute of Astronomy of the Russian Academy of Sciences, corresponding member of the Russian Academy of Sciences.
“If journalists ask me if there is life on Mars, I answer:“ Already have. ”It is impossible to sterilize spacecraft absolutely. The highest degree of sterilization, as far as I know, reaches several hundred microorganisms per square meter. It is clear that they exist and turned out to be very life is incredibly difficult to create, but it is also difficult to destroy, “he said at a meeting of the Presidium of the Russian Academy of Sciences.
