As reported by “MK” in the Institute of Biomedical Problems, Russian Academy of Sciences, the first findings of an aqueous origin were made last year during the release of our astronauts in EVA and taking bioassay with porthole special tampons. Microbiologists discovered in samples returned to earth, the DNA of plankton and aquatic bacteria. Where they came from space, just say goodbye, no one can.
Most likely, these stable forms rose to the Earth’s orbit with the spacecraft. Argued that at the Baikonur Cosmodrome no water sources in this case are not important – particles and bacteria can enter the aquatic environment in the blocks of the spacecraft with the rain, or just with atmospheric moisture during transport or before the actual launch. In any case, this question is very interested scientists.
Therefore, the present inhabitants of the ISS – Alexander Skvortsov and Oleg Artemyev, EVA August 18 – again took bioassays with the window in the experiment “Test”. Work is done by a number of organizations, which, after transporting the samples to the ground to hold their genetic and microbiological studies.
