Bennu’s Topography


This three-dimensional view of near Earth asteroid Bennu was created by the Canadian Space Agency’s Laser Altimeter aboard NASA’s OSIRIS-REx spacecraft. The colors represent the distance from the center of Bennu: dark blue areas lie about 60 meters below the peaks indicated in red. Because some parts of the asteroid have not yet been measured, there are gaps in the image.

Bennu Up Close


This wide shot and pair of close-ups was taken by the OSIRIS-REx spacecraft. They show a region in asteroid Bennu’s northern hemisphere. The wide-angle image (left) covers a 180 m wide area filled with rocks, including some large boulders, and a “pond” of regolith that is mostly devoid of large rocks. The two close ups show details of areas in the wide image, specifically a 15 m boulder (top) and the regolith pond (bottom). The close up frames are 31 m) across. The boulder depicted is about the same size as a humpback whale.

New Views of Bennu


This mosaic image above was stitched together using 12 PolyCam images collected on 2 December by the OSIRIS-REx spacecraft while it was about 24 km from Bennu. The animation below show a preliminary shape model of the asteroid created image data taken during the spacecraft’s approach to Bennu during November. This 3D model shows features on Bennu as small as 6 m.

Approaching Bennu


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.
