                         interaction impact on the prediction of the main aerodynamic 
                         surface loads of a space reentry capsule. In the present work 
                         different surface accommodation coefficients have been simulated 
                         by using the Direct Simulation Monte Carlo (DSMC) method in 
                         conjunction with the Cercignani- Lampis-Lord gas surface 
                         interaction model. The DSMC calculations examine differences in 
                         predictions of aerodynamic forces and heat transfer between full 
                         and partial surface accommodations for a hypersonic flow past to 
                         the Brazilian prototype reentry capsule SARA (acronym for 
                         SAt{\'e}lite de Reentrada Atmosf{\'e}rica). Seven combinations 
                         of normal and tangential accommodation coefficients associated to 
                         five different altitudes were used in the simulation. For the flow 
                         conditions considered, the analysis showed that stagnation point 
                         heating are sensitive to changes on either normal or tangential 
                         accommodation coefficients. Results substantiate that it becomes 
                         imperative to take surface accommodation into account in order to 
                         make accurate predictions of the aerodynamic forces acting on the 
                         capsule surface, and of the heat transfer rates to the surface of 
                         the capsule at hypersonic flow.",
