In this talk I will provide an overview of recent benchmarking experiments and modeling that was conducted at the Johns Hopkins Applied Physics Laboratory in support of the upcoming Psyche, MMX and Dragonfly missions. These experiments have revealed that whilst there is reasonable agreement between measured data and simulations significant improvement is required, particularly in modeling gamma ray production, to meet the needs of near-term planetary nuclear spectroscopy investigations.
