Abstract

The OSIRIS-REx mission successfully entered a closed orbit around target asteroid Bennu for the first time on December 31, 2018. Due to the extremely low gravity of the asteroid, a specific orbit design was necessary to balance the perturbations provided from solar radiation pressure in order to maintain spacecraft safety, meet mission requirements, and demonstrate orbit stability over a propagation period of several months. This paper describes the design for OSIRIS-REx’s record-setting orbit and the as-flown performance of the spacecraft while it remained in orbit for two months without need for orbit maintenance.
