- Аннотация: The problem aiming qualitative change of an Apophis orbit when its movements in Solar system comes to an end is formulated in [Ostrik:1995, Ostrik:2010]. Instead of passive saving tactics the variant of use of this asteroid is considered for realization of large-scale space experiment. This experiment is shock interaction of an asteroid and the Moon. The organization of space scale collision will allow to solve a set of the physical questions concerning the Moon [Ostrik:2010]. Correction of an Apophis orbit on July 22, 2016 or on July 11, 2017 by means of making of an speed increment 7,33m/s for an asteroid is sufficient. As result of calculations by method [Kazantsev:2002] this correction provides Apophis redirection to the Moon surface.Superficial and near-surface explosions lead to asteroid fragmentation that is undesirable for a set of reasons. The variant of the outlying explosion is more preferable. Results of calculations show that the speed increment 10m/s is realized at the power of outlying explosion about 10 … 40Mt TTN. It depends on distance before explosion (50 … 100m), thermodynamic properties of Apophis material and its porosity. In case of outlying explosion the basic factor is mechanical action of X-ray and neutron fluxes \cite{Grib:1997}. We used Planck spectrum for estimates of mechanical radiation action.
