Abstract

Data was developed for the thermodynamic properties of Mars atmosphere at, or near, the surface, where freezing and thawing of the CO2 can occur. Data must be known to develop missions that explore the surface and lower atmosphere of Mars. Thermodynamic and transport properties of the Martian atmospheric gases have been developed for atmospheric entry of the lower part of the Mars atmosphere as a function of temperature, mole fraction of CO 2, and mass ratio of N2 to CO2. the Mars surface temperature and pressure varied daily and seasonally. Real-gas effects were shown to be negligible. the surface pressure and temperature were such that N2 always remained at the gaseous state.
