OSIRIS-REx Observes an Asteroid in Action (VIDEO) NASA/Goddard Space Flight Center This video is under embargo. Please login to access this video. Caption Using data collected by NASA's OSIRIS-REx mission, this animation shows the trajectories of particles after their emission from asteroid Bennu's surface. The animation emphasizes the four largest particle ejection events detected at Bennu from December 2018 through September 2019. Additional particles, some with lifetimes of several days, that are not related to the ejections are also visible. Credit M.
