		<abstract>Hypersonic flow over forward-facing steps is examined for a range of freestream Mach number from 5 to 25 at zero-degree angle of incidence. The work is motivated by interest in assessing the impact of surface discontinuities on hypersonic configurations in the Earth reentry. The Direct Simulation Monte Carlo (DSMC) method has been employed in order to examine the flowfield structure on these forward-facing steps. The results presented highlight some significant differences on the primary properties due to variations on the step frontal-face height and on the freestream Mach number. Interesting features observed on the velocity, density, pressure, and temperature profiles showed that small frontal-face thickness, compared to the freestream mean free path, still has important effects on the flowfield structure for the freestream Mach number range investigated.</abstract>
