The OSIRIS-REx mission, launching in September 2016, plans to return a sample of asteroid Bennu to Earth in 2023 so that scientists can study pristine material left over from the early solar system. Dante Lauretta, Principal Investigator for OSIRIS-REx, provides an overview of this asteroid sample return mission. Learn more at http://www.nasa.gov/osiris-rex and http://www.asteroidmission.org
