Photographs of the two known natural satellites of Mars - Phobos and Deimos - illustrate the importance of impact cratering in the postformational histories of the two moons and, by inference, the asteroids and other small planetary satellites. The objectives of the present study are to investigate qualitatively the impact cratering process on small bodies, to apply some of these considerations to the observed surfaces of Phobos and Deimos, and to consider the asteroids briefly in the light of these results. The cratering process on small bodies is discussed in three stages: compression, excavation, and modification. Nonescaping and escaping ejecta are considered.
