High Fidelity Radiation Pressure Models for Spacecraft.

One area I am particularly excited about is the development of radiation force models for spacecraft in Low Earth Orbit. One of the major challenges that remains in the spacecraft operations community is the lack of an open-source, easy-to-use, and widely accepted community tool for high-accuracy radiation pressure modeling. This gap exists largely because ray-tracing software, which is key to accurate radiation pressure models, is daunting, compute-heavy, and time-consuming to run. Until recently, this level of modeling has been seen as overkill for most low-Earth orbit applications, where drag forces—far more uncertain—dominate the error budget.
