Bennu TAG Surface Change

This visualization begins with a top-down view of a high resolution digital terrain model (DTM) of the Nightingale TAG sample site on Bennu. As the camera moves closer, data representing the surface height change pre-post TAG fades on. The surface height change as a result of the TAG event is represented by both a color map and by offsetting the original DTM to reveal the TAG crater. The DTM offset is applied to the surface region within ~7.5 meters of impact, which is highlighted for emphasis. With this color bar, yellows, greens, and blues represent a decrease in elevation, light red represents no change in elevation, and dark red represents an increase in elevation. Thruster marks and a region of ejected surface material are labeled. The camera does a 360 degree spin around the sample site before returning to a top-down view of the color-mapped data.

The Origins Spectral Interpretation Resource Identification Security-Regolith Explorer (OSIRIS-REx) spacecraft arrived at near-Earth asteroid Bennu in December 2018. After studying the asteroid for nearly two years, the spacecraft successfully performed a Touch-And-Go (TAG) sample collection maneuver on October 20, 2020. The change in surface topography as a result of the sample collection maneuver is observed by comparing pre-TAG and post-TAG digital terrain models (DTM), revealing the newly-formed TAG crater.

OSIRIS-REx will return its sample of Bennu to Earth in September 2023.
