OLA's Complete 3D Map of Bennu

This three-dimensional view of asteroid Bennu was created by the OSIRIS-REx Laser Altimeter (OLA), contributed by the Canadian Space Agency, on NASA's OSIRIS-REx spacecraft. This 3D global map of Bennu's topography was created from about 20 million measurements taken by OLA. From Feb. 12 through 17, OLA made more than 11 million measurements of the distance between OSIRIS-REx and Bennu's surface as the spacecraft flew less than 1.2 miles (2 km) above the surface. From July 2 through August 5, OLA took additional measurements using its low-energy laser transmitter (LELT). The LELT is designed to fire 10,000 light pulses per second at the asteroid, and operates approximately 700 meters above Bennu's surface.

OLA obtained these measurements by firing laser pulses at Bennu and measuring the amount of time it takes for the light to bounce off the asteroid's surface and return to the instrument. That time measurement is then translated into altitude data. Using this data, the OLA team created the 3-D model of Bennu's surface. The colors represent the distance from the center of Bennu: dark blue areas lie approximately 197 feet (60 meters) lower than peaks indicated in red.

Rock on Boulder's Edge

This image shows a small area just north of asteroid Bennu's equatorial region. Pictured is a diversely-shaped group of smaller rocks surrounded by larger boulders. The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on July 8, from a distance of 0.4 miles (0.7 km). The field of view is 31 ft (9.5 m). For scale, the small rock perched on top of the large boulder (upper left) is 1.6 ft (0.5 m) across, which is about the size of a large watermelon. The image was obtained during the mission's Orbital B phase. When the image was taken, the spacecraft was over the northern hemisphere, pointing PolyCam nearly straight down.

Textured Boulder Near Bennu's Largest Boulder

This image shows a detailed view of a boulder feature located near asteroid Bennu's largest boulder in the southern hemisphere. The long morning shadows emphasize the feature's series of ledges, and a small, light-colored rock sits on one of the ledges. The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on July 9, from a distance of 0.4 miles (0.7 km). The field of view is 31 ft (9.6 m). For scale, the light-colored rock is 2.8 ft (0.9 m), which is about the size of a pickup truck tire. The image was obtained during the mission's Orbital B phase. When the image was taken, the spacecraft was over the southern hemisphere, pointing PolyCam nearly straight down.

Bennu's South Pole at Dawn

This image shows a region near asteroid Bennu's south pole, where smaller rocks and larger boulders are mixed together. It was captured at 6:40 am Local Solar Time, so the long, morning shadows are cast to the left. The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on July 13, from a distance of 0.4 miles (0.7 km). The field of view is 32 ft (9.7 m). For scale, the small, round boulder that is bright in color at the top center of the image is 1 ft (0.4 m) across, which is about the size of a wine bottle. The image was obtained during the mission's Orbital B phase. When the image was taken, the spacecraft was over the southern hemisphere, pointing PolyCam slightly north and to the west.
