The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) was the third mission in NASA’s New Frontiers program. OSIRIS-REx launched out of Cape Canaveral, Florida on September 8, 2016, with a science goal to return a minimum of 60 g of a primitive asteroid’s surface, specifically the near-Earth asteroid Bennu. The sample return capsule (SRC) successfully touched down at UTTR on the morning of September 24, 2023. The entry, descent, and landing (EDL) sequence had an off-nominal deployment of the parachute, but the spacecraft safely landed within the pre-flight prediction of the landing ellipse and the payload was safely recovered. This paper discusses the pre-flight EDL modeling and simulation and focus on predictions for EDL operations. Flight observations such as timeline are compared to the predicted timeline produced by the EDL simulation.
