Electron production from the high temperature shock layer of blunt re-entry bodies are considered at high altitudes. The dissociation and subsequent ionization of air species due to the high flight speeds are predicted by analytical techniques with the consideration of the prevalent viscous effects at low density throughout the flow and with chemical relaxation of these species. The effect of vibrational nonequilibrium is also determined. Finally the spatial distributions of air species, temperature, velocity, and electron concentrations over a sphere-cone body, the Trailblazer, is mapped in detail for several altitude velocity conditions.
