Bennu visualization on the cover of Science

This visualization of Bennu was selected for the cover of the November 6th special issue of Science. The image was created using high-resolution imagery and laser altimetry data from the OSIRIS-REx spacecraft. Multiple data layers were wrapped to a detailed 3D model of the asteroid, representing just a few of the recent science results from the mission.

Data Used:
OSIRIS-REx/OCAMS/Imagery
Observed Data
The OSIRIS-REx Camera Suite (OCAMS) consists of three cameras: PolyCam, MapCam, and SamCam. These cameras will “see” asteroid Bennu as the spacecraft first approaches it. OCAMS will then provide global image mapping of Bennu’s surface and more detailed images of potential sample sites. Finally, OCAMS will record the entire sampling event during the touch-and-go (TAG) maneuver.

OSIRIS-REx/OLA/LIDAR
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 will emit laser pulses at the surface of Bennu, which will reflect back from the surface and return 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 the spacecraft and the surface of Bennu can be computed using the speed of light. This allows OLA to provide high-resolution topographical information about Bennu during the mission. OLA ranging measurements will also support other instruments and navigation and gravity analyses.
Note: While we identify the data sets used in these visualizations, we do not store any further details nor the data sets themselves on our site.
