The frequencies of the formation of explosive craters of the given sizes on the surface of the satellite «Ocean-O» were calculated. For this purpose the data on the flux of sporadic meteoroids and space debris in the near-Earth space and the E. Opik's theory of crater formation were used. The results show that the probabilities of destructive collisions with two components mentioned above are approximately equal. The probability of the collision of a space vehicle with a potentially hazard particle depending on the duration of its stay in the orbit is also estimated. The parameters of the craters formed are shown to depend strongly on both the speed and the angle of incidence of the particle. As an example, the calculation is done for the well-known Arizona crater on the Earth's surface.
