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.

Bennu 360


This set of images shows one full revolution of the asteroid Bennu. The OSIRIS-REx spacecraft acquired an image for every 10 degrees during the asteroid’s 4 hour and 11 minute rotation from a range of just under 200 km last Friday. Bennu is approximately 200 pixels wide in the images.

Closing in on Bennu


This set of 16 images was taken the OSIRIS-REx spacecraft during its approach on the asteroid Bennu during the last half of October. From the 12th through the 29th, the long-range PolyCam camera took one optical navigation image per day, except on the 16th and 17th when PolyCam was not scheduled to take images. The spacecraft was roughly 44,000 km from Bennu when the first image was taken. The last image was taken from a distance of around 320 km.
