The entry vehicle carried a set of instrumentation installed on the heatshield and backshell to measure aerodynamic and aerothermal performance, named the Mars Entry, Descent, and Landing Instrumentation 2 (MEDLI2). While post-flight analysis of the data was initially conducted to compare design predictions with flight data, there remained many unanswered questions regarding the actual environments experienced by Mars 2020 and why design predictions disagreed with measured data. Therefore, a deep dive effort was stated at NASA to conduct a detailed investigation of the flight data and to assess predictive capabilities of state-of-the-art modeling techniques. This talk will provide an overview of this effort along with a current status. Additionally, remaining challenges and opportunities will be identified as points of departure for future work. 收起
