Mars landing vehicle descent propulsion is discussed in light of constraints of mission, environment, and interfacing functions; presence of largely undefined, tenuous atmosphere is shown to produce great variability of initial and boundary conditions for propulsion phase of descent; current requirement for prelaunch, in-situ, thermal sterilization and problems encountered in sterilization feasibility program; landing site alteration and landing mechanics; typical Mars propulsive lander mission objectives and constraints are tabulated, impact of these and other interfaces on design requirements and design criteria; conceptual monopropellant mechanization is presented which satisfies most of these constraints.
