    PRESS RELEASE In June 30, 2008 we have anniversary of Tunguska event in Siberia. Scientists try to find fragments of Tunguska space impactor during 100 years. A lot of theories were suggested for explanation of mysterious Tunguska catastrophe in 1908.


    Some scientists think that it was small asteroid and other scientists consider space impactor as small comet. In July 1988 russian scientist Andrei Zlobin (CIAM, Moscow) found the fragment of hard substance at the region of Tunguska catastrophe. It was the subject with wonderful aerodynamic form which looked like "dental crown" (see photo). There is well visible melting on the edges of fragment and the color of the body's surface looks like rusty-brown.

    Last year Zlobin's paper was accepted to 2007 Planetary Defence Conference at Washington. Russian scientist described his work on Quasi Three-dimensional Modeling of Tunguska Comet Impact. Twenty years was necessary for Zlobin before he obtained calculative confirmation of coordinates of regions, where small heavy fragments could be discovered. One of these regions is located not far from the place where "dental crown" was found. That is why we can say strongly that one fragment of Tunguska impactor is already found.

    In 2009 Dr. Zlobin have plan to write paper about processes which produced "dental crown" form of fragment. Today scientist makes mathematical model concerning these processes. This work requires complicated calculations including numerical modeling of gasdynamics, heat transfer and stress analysis. After this modeling we will have more accurate information concerning parameters of Tunguska comet impact. "I can't exclude some surprise in future" - Andrei Zlobin say.

    Let us mention words of academician Dr.Sc. N.V.Vasilijev too. Vasilijev spent above 40 years of his life for investigation of Tunguska catastrophe. He said: "It is not excluded that A.E.Zlobin are not far from truth in something, and physics of Tunguska phenomenon will be necessary to rewrite from position of "clean page" in future. This words N.V.Vasilijev used in his final book "The Tunguska meteorite. Space phenomenon of 1908 summer" [Moscow, 2004].
