This event took place live at 2pm EST on December 10, 2018 at the American Geophysical Union conference in Washington DC. Watch this video on YouTube. || 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 HeadquartersDante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, TucsonAmy Simon, OVIRS deputy instrument scientist at NASA Goddard Space Flight Center Michael Nolan, OSIRIS-REx science team chief at the University of Arizona, TucsonFor more information, go to nasa.gov/osiris-rex or asteroidmission.org. || TAGSAM Banner ImageCredit: NASA/Goddard/University of Arizona This image shows an artist’s rendering of the OSIRIS-REx spacecraft collecting a sample of material from Bennu’s surface in 2023. || 1.

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. || 18. Lauretta – Mission Science ObjectivesCredit: University of Arizona || 19.
