Abstract
The space exploration is nowadays assisted by realistic modeling of re-entry conditions of space vehicles in planetary atmospheres, for the design of thermal protection systems. The detailed kinetic modeling relies on the accurate description of elementary process dynamics, including the role of the excitation of the internal degrees of freedom of chemical species. Efforts in the construction of a complete and consistent dynamical information are presented, focusing on hydrogen plasmas relevant to the Jupiter atmosphere. Examples of numerical experiments are given, emphasizing the relevance of the adopted state-to-state approach in reproducing the onset of non-equilibrium internal distributions governing the plasma system evolution.
