Unlike most chapters, whose content is mutually exclusive to that contained
elsewhere in the same book, there was intentional redundancy between some of the
material in this chapter and previous chapters. The reason is that both satellites and
space debris (each the subject of a previous chapter), were deemed individual and
independent risks to those residing on the Earth and spacefarers. But for the purposes of
the present chapter, both are also important factors in space saturation. In this chapter
space saturation was defined and exemplified. We learned about the linear nature of
space saturation. The constant reality of cosmic collisions was explained, exemplified
and quantified. Collisions involving space satellites, asteroids, comets, planets,
centaurs, galaxies and other space bodies were described. The past, present and future
incidence of collisions was estimated.
