OSIRIS-REx's approach to Bennu

OSIRIS-REx's approach to Bennu
OSIRIS-REx's approach to Bennu This video shows the OSIRIS-REx spacecraft’s view of Bennu during the final phase of its journey to the asteroid. From 17 August through 27 November, the spacecraft’s PolyCam camera imaged Bennu almost daily as the spacecraft covered the remaining 2.2 million kilometers toward the asteroid. The final images were obtained from a distance of about 65 km kilometers. During this period, OSIRIS-REx completed four maneuvers slowing the spacecraft’s velocity from approximately 491 m/s to 0.04 m/s relative to Bennu, which resulted in the slower approach speed at the end of the video.
