Abstract

This paper outlines and solves the problem of imaging asteroid (101955) Bennu in the presence of spacecraft state perturbation during OSIRIS-REx’s approach trajectory. The problem is that the area a mosaic must cover changes size as the spacecraft state is perturbed. We developed and applied a method for determining how much to over-image the the area around Bennu to satisfy specific observation requirements. We also implemented machine learning classification techniques to explore their utility at predicting mosaic coverage for future OSIRIS-REx observations.
