A Web Around Asteroid Bennu – Visualizations

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 spacecraft will remain in asteroid Bennu’s vicinity until May 10, when the mission will enter its Return Cruise phase and begin its two-year journey back to Earth. This data visualization presents the mission’s complete trajectory during its time at Bennu.

Mission:
OSIRIS-REX

Data Used:
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.
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.
