Description
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.

Bennu
You talkin' to me? You talkin' to me? You're coming at me with your OSIRIS-REx. You want a piece of ME?! Well I'll give you a piece of me. Take a good long look at what you dismissively describe as my rubble pile self. That rubble is a big pile of rocks I can throw at you, and if you're not careful, I'll bring my whole bad self over to planet Earth on my own little walk about the galaxy, aided by some Yarkovsky maneuvers where I take some solar energy in and radiate it out just in the right direction to put me on a collision course with Earth. So if you want a sample of Bennu, be careful what you ask for.
