The Advanced Supersonic Parachute Inflation Research and Experiment (ASPIRE) was a series of sounding rocket flights aimed at understanding the dynamics of supersonic parachutes that are used for Mars robotic applications. Three flights for ASPIRE occurred off the coast of Wallops Island, VA in Oct. 2017, Mar. 2018, and Sept. 2018 and successfully demonstrated deployment and inflation of the Mars Science Laboratory and Mars 2020 mission parachute. Prior to all three flights, a multi-body flight dynamics simulation was developed to predict the parachute dynamics and was used, in conjunction with other tools, to target Mars-relevant flight conditions. After each flight, the reconstructed trajectory was used to validate the preflight dynamics simulation and recommend changes to improve predictions for future flights in the ASPIRE program. This paper describes the parachute models and flight mechanics simulation used to target conditions for the three flights and the post-flight comparison of the tools.
