Post-Flight Aerodynamics Assessment of the Artemis-I Booster Separation Event

The successful launch of the Artemis-I mission in November 2022 was made possible, in part, by years of rigorous vehicle simulation and scaled testing. Correctly anticipating the complex physics of the booster separation event was one of many necessary challenges. The successful booster separation of Artemis-I yielded flight data with which the fidelity of these predictions could be assessed. In this paper, the flight data and flight simulations are reconciled to present a unified assessment of the booster separation event. With this assessment, predictive confidence can be reinforced in support of the crewed Artemis-II mission.
