Bennu TAG Surface Change

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.

Data Used:
The OSIRIS-REx Laser Altimeter (OLA) is a scanning LIDAR (Light Detection and Ranging). LIDAR is similar to RADAR, but it uses light instead of radio waves to measure distance. OLA emitted laser pulses at the surface of Bennu, which reflected back from the surface and returned a portion of the laser pulse to the LIDAR detector. By carefully measuring the time difference between the outgoing pulse and the incoming pulse, the distance from the spacecraft to the surface of Bennu was computed using the speed of light. This allowed OLA to provide high-resolution topographical information about Bennu during the mission.
Observed Data
The OSIRIS-REx Camera Suite (OCAMS) consists of three cameras: PolyCam, MapCam, and SamCam. These cameras captured a wealth of imagery during OSIRIS-REx’s time at asteroid Bennu. To help mission planners select a site on Bennu for sample collection, OCAMS provided global image mapping of the asteroid’s surface and more detailed images of potential sample sites. OCAMS also recorded the sampling event during the touch-and-go (TAG) maneuver.
