OSIRIS-REx spent over two years near the asteroid Bennu, which is a third of a mile (500 meters) wide. During that time, the spacecraft gathered information about Bennu’s size, shape, mass, and composition while monitoring its spin and orbital trajectory. Before leaving the near-Earth object May 10, 2021, the spacecraft scooped up a sample of rock and dust from the asteroid’s surface. OSIRIS-REx will return the sample to Earth Sept. 24, 2023, for further scientific study.
The teleconference will stream live online at: http://www.nasa.gov/live\r
Participants in the briefing will be:\r
•\tDante Lauretta, study co-author and OSIRIS-REx principal investigator at the University of Arizona in Tucson\r
•\tDavide Farnocchia, study lead author and scientist with the Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory in Southern California\r
•\tJason Dworkin, OSIRIS-REx project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland\r
•\tLindley Johnson, planetary defense officer at NASA’s Planetary Defense Coordination Office at NASA Headquarters in Washington
