NASA’s OSIRIS-REx spacecraft mission, launched on Sept. 8, 2016, is the first U.S. mission designed to retrieve a pristine sample of an asteroid and return it to Earth for further study. The mission’s target is Bennu, a carbon-rich near-Earth asteroid that is potentially hazardous, representing an approximately 1 in 2,700 chance of impacting the Earth late in the 22nd century.
