OSIRIS-REx Arrives at Bennu -- 2018 AGU Press Conference

  • Released Monday, December 10, 2018
View full credits

NASA’s OSIRIS-REx mission presented the science results gained during the spacecraft’s approach toward the asteroid Bennu at a press conference hosted during AGU’s Fall Meeting at 2 p.m. ET, Monday, Dec. 10.

The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft, which launched on Sept. 8, 2016, started asteroid science operations on Aug. 17, 2018, while still 1.4 million miles from the asteroid Bennu. Between that time and the spacecraft’s arrival at Bennu on Dec. 3, the mission made a number of discoveries about the asteroid.

The mission represents a valuable opportunity to learn more about the origins of our solar system, the sources of water and organic molecules on Earth, and the hazards and resources in near-Earth space.

The briefing participants are:

Jeffrey Grossman, OSIRIS-REx program scientist at NASA Headquarters
Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson
Amy Simon, OVIRS deputy instrument scientist at NASA Goddard Space Flight Center

Michael Nolan, OSIRIS-REx science team chief at the University of Arizona, Tucson

Lauretta – Twelve-Image PolyCam Mosaic of Bennu Credit: NASA/Goddard/University of Arizona This mosaic image of asteroid Bennu is composed of 12 PolyCam images collected on Dec. 2 by the OSIRIS-REx spacecraft from a range of 15 miles (24 km). The image was obtained at a 50° phase angle between the spacecraft, asteroid and the Sun, and in it, Bennu spans approximately 1,500 pixels in the camera’s field of view.

The inset photograph shows the OSIRIS-REx Touch-and-Go Sample Acquisition Mechanism (TAGSAM) sampling head extended from the spacecraft at the end of the TAGSAM arm. The spacecraft’s SamCam camera captured the image on November 14, 2018 as part of a visual checkout of the TAGSAM system, which was developed by Lockheed Martin Space to acquire a sample of asteroid material in a low-gravity environment. The imaging was a rehearsal for a series of observations that will be taken at Bennu directly after sample collection.
