Walkabout the Galaxy

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.

Our guest, André Bormanis, has spent a considerable amount of time thinking about extraterrestrial intelligence, as well as warp travel, holodecks, artificial life forms, and more. Having spent more than a decade as an advisor and producer on the Star Trek franchise, André is now an executive producer and writer on "The Orville", Seth MacFarlane's trekkiest of shows. André joins the astroquarks for a discussion of Trek, humor, and the vexing Fermi paradox. Maybe we're just too early to the party. Check it out, and check out "The Orville", plus a special Trek trivia on this episode of Walkabout the Galaxy.
