A billion-dollar spacecraft, a daring deep-space mission, and one of humanity’s biggest questions: Where did we come from? NASA’s OSIRIS-REx set out to collect a pristine sample from asteroid Bennu, a cosmic time capsule that may hold clues to the origins of life in our solar system. But the journey was anything but easy. Guests: Erica Jawin, postdoctoral research geologist in the Center for Earth and Planetary Studies at the Smithsonian’s National Air and Space Museum and member of the OSIRIS-REx mission Tim McCoy, curator of meteorites at the Smithsonian's National Museum of Natural History and deputy mission sample scientist for the OSIRIS-REx mission Mike Moreau, deputy project manager in the Space Science Mission Operations Project at NASA’s Goddard Space Flight Center
