Space mystery: the Chelyabinsk meteorite was rusty Bashny.Net

This conclusion was made by researchers from the Institute of Geology and Geochemistry, Ural branch (IgG UB RAS). Says the head of the group for the study of meteorite by academician Victor Koroteeva, the presence of rust − a sign that the rocks of the meteorite could contain moisture.





To obtain reliable information in the study of the meteorite is quite important that the samples not subjected to collision with the Ground, as well as weathering and corrosion in earth conditions. "All these conditions have to be met. The studied fragments had not reached the soil layer and removed from the snow from a depth of 20-50 cm, shortly after the fall," − says Victor Koroteev.
