NASA’s OSIRIS-REx mission will send a spacecraft in September 2016 to the asteroid Bennu in order to extract a sample and bring it back to earth. Bennu is a carbon-rich asteroid that records the earliest history of our Solar System, and by studying a piece of it we could discover the origin of life. Bennu is also one of the most potentially hazardous asteroids. It has a relatively high probability of impacting the Earth late in the 22nd century. OSIRIS-REx will determine Bennu’s physical and chemical properties. This will be critical for future scientists to know when developing an impact mitigation mission.
