Scientists have found that microbes could not “chew” a hole in the Union

INTERFAX.RU Specialists of the Institute of biomedical problems of RAS tested the hypothesis that the appearance of the hole in the hull of the Union could be involved in microorganisms, it has not been confirmed, reported “Interfax” leading researcher of IMBP RAS Svetlana Poddubko.

“Our specialists and specialists from other organizations of space industry, who participated in the study for samples taken in the area of the hole, came to the conclusion that the number of microorganisms on the ISS, not enough to cause corrosion and destruction of metal structure in the center of the notorious hole.
