Bennu in Stereo

NASA – OSIRIS-REx Mission logo.

April 3, 2019

This set of stereoscopic images provides a 3D view of the large, 170-foot (52-meter) boulder that juts from asteroid Bennu’s southern hemisphere and the rocky slopes that surround it. The stereo pair was created by stereo image processing scientists Dr. Brian May, who is also the lead guitarist for the rock band Queen, and Claudia Manzoni. In January, May and Manzoni formally joined NASA’s OSIRIS-REx mission science team as collaborators to create stereoscopic data products, which will be used by the team while selecting a sample collection site on Bennu.

“I’m proud to have been adopted as a collaborator on the OSIRIS-REx team, along with my colleague Claudia Manzoni,” said May. “Our passion is producing stereoscopic (3-D) images from the astounding data that the OSIRIS-REx mission has been collecting.”

The two images in this stereo pair were taken from slightly different viewpoints, with one of the images meant for the left eye and the other for the right. The two images are then combined by the brain to give the perception of depth. To see the pair in 3D, cross your eyes and relax your vision until there are three images, then focus on the center image. Tilt your head as needed to bring the image into focus. A version of the image suitable for viewing through a stereoscope can be found here: https://www.asteroidmission.org/bennus-boulder-1-stereo-pair-stereoscope-version/

The cropped and processed images were obtained on December 1 and 2, 2018, by the PolyCam camera during the spacecraft’s final approach toward the asteroid.
