From 700,000 to 1 - Why OSIRIS-REx is Going to Asteroid Bennu

In September of 2016, the OSIRIS-REx mission will launch on a seven-year mission to collect a sample of the near-Earth asteroid Bennu and return that sample to Earth in 2023. Over the past few decades, the number of known asteroids has exploded to nearly 700,000. LPL Staff Scientist Carl Hergenrother will explain why Bennu was selected as the target of the OSIRIS-REx mission.
