OSIRIS-REx was the first U.S. mission to retrieve a sample from an asteroid and deliver it to Earth. So, of the more than one million known asteroids in our solar system, why did NASA choose the near-Earth asteroid Bennu for its target? Three factors made Bennu ideal: proximity to Earth, the right size and spin rate, and a carbon-rich composition. Now, scientists studying the Bennu samples are learning more about the history of our solar system and the origins of life – thanks to this one-in-a-million asteroid.
