We are joined by asteroid expert and "b" quark Dr. Zoe Landsman to discuss the remarkable discovery by the OSIRIS-REx mission that the asteroid it is orbiting, Bennu, is spitting pebbles and rocks out into space. The mechanism for this remains a topic of research. Also, another thing named after Enrico Fermi, another super moon with a silly name, and examining Apollo samples that have been sealed since they were recovered from the lunar surface. All in all, just another episode of Walkabout the Galaxy.
