75-Centimeter Shape Model (Mar. 2019)

After studying asteroid Bennu at close range for three months, the OSIRIS-REx mission team has developed a new shape model with a 75-centimeter resolution. This more precise model, which was created using imagery taken by OSIRIS-REx’s PolyCam camera, shows features on Bennu smaller than one meter.

Preliminary Shape Model (Nov. 2018)

This preliminary shape model of asteroid Bennu was created from a compilation of images taken by OSIRIS-REx’s PolyCam camera during the spacecraft’s approach toward Bennu during the month of November, 2018. This 3D shape model shows features on Bennu as small as six meters.

Radar-Based Shape Model (2013)

The OSIRIS-REx  team planned the spacecraft’s mission using a shape model of asteroid Bennu that was developed in 2013 and based on radar observations from Arecibo Observatory and Goldstone tracking station. Although the original model did not predict the surface topography of Bennu in detail, at least one large rock formation was predicted in the southern hemisphere.

Pre-TAG DTM

OLA data were used to develop a digital terrain model (DTM) of the Nightingale site with a ground sample distance of 5 cm produced with data collected before sampling. These data show that the sampling event occurred on a 20–30° north-to-south slope, relative to Bennu’s gravity vector.

Post -TAG DTM

PolyCam images of the sampling region were used to develop a digital terrain model (DTM) of the Nightingale site following sampling. The post-sampling DTM used in this analysis was developed with stereophotoclinometry with a ground sample distance also equal to 5 cm per pixel, the same spatial resolution of the source images. The sampling event created an elliptical crater (9.0 × 6.5 m) centered at 55.997°, 44.971° with a depth of almost 70 cm. The total excavated volume is roughly twelve cubic meters.
