The Japan Aerospace Exploration Agency (JAXA) recently proposed a landing mission to Mars. To improve the feasibility of the mission, rarefied aerodynamics need to be accurately estimated for a precise determination of its flight path and landing site. This work has investigated rarefied hypersonic aerodynamics experimentally and numerically. A rarefied aerodynamic measurement scheme has been developed by using pendulous models in a hypersonic rarefied wind tunnel at JAXA, and the results have been compared with direct simulation Monte Carlo computations. Consequently, numerically predicted aerodynamic coefficients are consistent with the measured values.
