The comets play important role as a simulation laboratory for multiscale kinetic plasma processes which are key-role processes in space and laboratory plasmas. A development of multiscale combined numerical methods allows us to use more realistic cometary plasma models (see, e.g. [Häberli et al., 1997; Delamere et al., 1999; Bagdonat and Motschmann, 2002; Lipatov et al., 2002]). In this report, we develop a Particle-Ion--Fluid-Ion--Fluid--Electron method of kinetic ion-neutral simulation (see, e.g. [Lipatov, 2002]), which is based on a multiscale adaptive mesh, particle and algorithm refinement. This method takes into account charge-exchange and photoionization processes. The first results of such simulation of the dynamics of ions near comet Borrelly are discussed in this report. ~
