Note that in each case, the vehicle performance and configuration are driven (and ultimately constrained) by the chemical propellants employed. This section deals with a variety of advanced chemical propellant systems ranging from near-term high-energy fuels and oxidizers, to very advanced chemical propellants employing, in some cases, atomic (free-radical) or excited metastable species to achieve the maximum possible I sp that can be...
