Evening Shadows on Northern Boulder

This image shows a detailed view of a boulder located in asteroid Bennu's northern hemisphere. A shadow-covered depression can be seen on the lower portion of the boulder. The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on July 30, from a distance of 0.4 miles (0.7 km). The field of view is 32 ft (9.9 m). For scale, the width of the shadowed depression is 5 ft (1.5 m), which is about the width of the Lincoln Memorial's columns. 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.

Well-Lit Terrain in Bennu's Northern Hemisphere

This image shows a mixture of boulders, rocks, and fine-grained material located in asteroid Bennu's northern hemisphere. The surrounding region is free of large boulders, making this one of the most well-lit images taken during Orbital B phase. The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on July 30, from a distance of 0.4 miles (0.7 km). The field of view is 31 ft (9.4 m). For scale, the bright, sharp-edged rock just right of the image's center is 2 ft (0.7 m) long, which is about the length of a mailbox. 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.

Dramatically Lit Boulder at North Pole

This image shows a large boulder located near asteroid Bennu's north pole. The image was captured at 6:00 a.m. Local Solar Time, resulting in long morning shadows cast to the left. The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on July 30, from a distance of 0.4 miles (0.7 km). The field of view is 32 ft (9.9 m). For scale, the thin, bright rock just above the boulder (upper left) is 2 ft (0.7 m) long, which is about the size of an osprey. 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.

Site Osprey During Reconnaissance A

This is the highest-resolution image captured of candidate sample site Osprey as of October 12. Site Osprey is located near asteroid Bennu's equator in the northern hemisphere. Because the region of interest is so large, only a portion of the crater is shown in this image. Site Osprey's recognizable features are visible – there is a dark patch of material in the center of the crater, and a large, flat boulder on the northern crater wall (upper left). The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on October 12, from a distance of 0.6 miles (1 km). The field of view is 47 ft (14.2 m). For reference, the fracture in the large boulder (upper left) is 10 ft (3 m) long, which is about the length of a standing grizzly bear. The image was obtained during the mission's Reconnaissance A phase. When the image was taken, the spacecraft was over the northern hemisphere, pointing PolyCam south and to the west.

OSPREY


(11°, 88°)

Located near Bennu's equator, site Osprey is set in a small crater with a 33 ft (10 m) radius. Various areas within the crater are being evaluated for sample collection–one east of the crater's center and one west of the crater's center. These sampling areas have a 16 ft (5 m) radius. Given Osprey's geographical position on Bennu's equatorial bulge, it is possible that the region contains material from both the northern and southern hemispheres. The diversity of rock types in Osprey's surrounding area suggests that the regolith within Osprey may also be diverse. Osprey has the strongest spectral signature for carbon-rich material among the four sites. It also ranks second for the highest albedo and color variation among the candidate sites. A large, dark (low albedo) patch of material in the center of the site is of high scientific interest for the mission team.



STEREO PAIRS



This set of stereoscopic images provides a 3D view of site Osprey, located in Bennu's southern hemisphere. The two images in this stereo pair were taken from slightly different viewpoints, with one of the images meant for the left eye and the other for the right. The two images are then combined by the brain to give the perception of depth. To see the pair in 3D, print off this image and view it through a stereoscope. The cropped and processed images were obtained on April 4, 2019, by the PolyCam camera during Flyby 5A of the mission's Detailed Survey: Baseball Diamond phase.

ANAGLYPH



This anaglyph of site Osprey was made from the stereopairs seen above. Each stereoscopic image was encoded using filters of chromatically opposite colors—one made with red and the other with cyan. When viewed through color-coded anaglyph glasses, each of the two images reaches the eye it's intended for, and a 3D image is produced. Anaglyphs are helpful for selecting a sample collection site because they allow the team to intuitively understand the three-dimensional structure of things like boulders and craters.

BOULDER COUNTS

 

These Boulder Maps for site Osprey detail the number and location of boulders present within the region. Because Osprey has several possible sampling regions, a boulder count map was produced for each of these regions. The boulders are counted by the human eye, using a single image at a time. Many of these boulder counts were made by members of the public who participated in the CosmoQuest Bennu Mappers citizen science campaign. The boulder counter marks each boulder by the longest axis (point to point) in order to calculate maximum boulder size. Rocks that are 10-21 cm are marked in yellow. Anything larger than 21 cm is marked in red. Rocks and debris that are ingested by the spacecraft's Touch-and-Go Sample Mechanism (TAGSAM) head must be no more than 2.5 cm wide.

Bennu's Equator in the Morning

This image shows a variety of rocks with different textures and sizes located in asteroid Bennu's equatorial region. It was captured at 6:00 a.m. Local Solar Time, and as a result, the boulders cast long shadows to the left. The image was taken by the PolyCam camera on NASA's OSIRIS-REx spacecraft on August 5, from a distance of 0.4 miles (0.6 km). The field of view is 30 ft (9.4 m). For scale, the longest axis of the bright boulder in the upper right is 11 ft (3.3 m), which is about the size of a patio umbrella. The image was obtained during the mission's Orbital B phase. When the image was taken, the spacecraft was just south of the equator, pointing PolyCam straight down.

Bennu's Terminator During Orbital B

This image captures a view of asteroid Bennu's terminator at the equatorial region. Just right of the transition line between day and night is a small, shadowed crater (bottom center). The image was taken by the MapCam camera on NASA's OSIRIS-REx spacecraft on August 7, from a distance of 0.4 miles (0.6 km). The field of view is 521 ft (159 m). For scale, the crater is 119 ft (36 m) wide, which is about the size of the Statue of Liberty from her heel to the tip of her crown. The image was obtained during the mission's Orbital B phase. When the image was taken, the spacecraft was just north of the equator, pointing MapCam north.
