In the perspective of higher approximations of the Chapman-Enskog theory for transport property calculations, existing transport cross sections databases for interactions involving Earth atmosphere spec ies have been updated and extended to Mars atmosphere components, proposing a phenomenological approach for the derivation of the relevant elastic collision integrals in neutral-neutral and neutral-ion interactions. Inelastic collision integrals terms, due to resonant charge exchange channels, have been considered and the asymptotic approach extended to the estimation of charge transfer cross section of multiple resonant processes.
