This trio of images taken by the NASA Space Vehicle OSIRIS-REx shows a large shot and two close-up images of a region in the asteroid of Bennu's northern hemisphere. The wide-angle image (left) taken with the spaceship's MapCam camera shows a 180 meter wide area with many rocks, including some large boulders, and a regolithic "pond" mostly free of large areas. Rocks The two Closer images taken with the high-resolution PolyCam camera show details of the areas in the MapCam image, notably a 15 meter long boulder (top) and the regolith pond (bottom). The PolyCam frames have a diameter of 31 meters and the pictured boulder is about the same size as a humpback whale.
The images were taken on February 25 while the spacecraft was located within approximately 1.8 km of the Bennu) from the surface of the asteroid. The observation plan for that day provided a MapCam and two PolyCam images every 10 minutes, allowing this combination of context and detail of the Bennu interface.
