Postgraduate students of UrFU Grigory Yakovlev and the assistant professor of UrFU, Candidate of Physical and Mathematical Sciences, Nikolai Kruglikov with the participation of the Finnish physicist Thomas Kohaut have created a 3D-model of the largest fragment of the meteorite “Chelyabinsk” which fell on February 15, 2013.
The volumetric digital model was created in two steps: first they scanned the largest fragment weighing about 500 kilograms, then a small splinter. “It is important to preserve it for history” - Grigory Yakovlev says. “Of course, it is in a secure environment - under the hood in the Chelyabinsk museum of regional history. But it is not protected from weathering”. With the help of a 3D-model you can precisely determine the properties of the meteorite, in particular, its average density. The theoretically obtained data can be used to calculate the flight through the atmosphere at a high speed. Besides, now you can create copies of the meteorite fragments with the help of 3D-printers.
