The biannual Starship Congress attracts starry-eyed believers in humankind’s destiny among the stars. We talk with several of them about their ideas for technologies and science that may help pave the way. Science fiction author David Brin dropped by the Congress and spends a few fun and speculative minutes with us. The September Equinox edition of The Planetary Report is ready for all to read. Editor Emily Lakdawalla gives us a sneak peek. The Milky Way has at least 54 satellite galaxies? Who knew? Bruce Betts, that’s who.

This US research center has been part of more than 200 space missions, but it’s not a NASA facility! The Los Alamos National Laboratory in New Mexico gave the Voyager spacecraft their power sources, is building nuclear generators for future Martians, and accidentally invented the field of High Energy Astrophysics. That’s just some of what we’ll learn from Lab historian Alan Carr and longtime Lab astrophysicist Ed Fenimore. The Planetary Society’s Jason Davis has the latest news about India’s lunar lander, while Bruce Betts and Mat Kaplan go where no acronym has gone before.

As NASA struggles to return humans to the Moon by 2024, it's worth asking: why did it stop in the first place? Space historian John Logsdon joins the show to discuss the politics behind the decision to abandon the Moon in 1972. Casey and Mat also discuss the proposal to offer a $2 billion prize for sending humans back to the Moon and establishing a base there, and why that's not good public policy.
