This series of images shows the OSIRIS-REx spacecraft’s view of Bennu during its final approach to the asteroid. They were taken beginning in mid August using the spacecraft’s PolyCam camera. The last images were taken on 27 November when the spacecraft was about 65 km away from the asteroid. During the approach, the spacecraft’s velocity with respect to Bennu slowed from around 491 m/s to about 0.04 m/s, which resulted in the seemingly slower approach speed at the end of the video.
