What an asteroid 200 million miles away can tell us about life, space, and the early solar system

NASA's OSIRIS-REx has touched down on the asteroid Bennu and successfully grabbed a sample for scientists to study back on earth. So why are they interested in this particular asteroid, and what are they hoping to learn? Dr. Harold Connolly, Jr., Founding Chair and Professor in the Department of Geology at Rowan University and Co-Investigator and Mission Sample Scientist on the OSIRIS-REx mission team joined KYW Newsradio In Depth just a few hours before the spacecraft made contact with the asteroid to talk about the mission and the secrets the team hopes Bennu wants to tell.
