Ann Druyan wishes you a happy Sagan Day

In a jam-packed episode, we’ll talk to a discoverer of a distant, lonely planet that wanders the galaxy, and then turn to plans to send a radically-simple sample collection system to the Moon and Mars’ moon Phobos. Planetary Society CEO Bill Nye will add his congratulations for the PlanetVac team. We’ve also got a signed copy of Bill’s latest book for the winner of the new What’s Up space trivia contest.

At least two ambitious, smart asteroid mining companies have gone bust. Joel Sercel makes the case that his new effort comes at a much better time, and with a better approach. He’ll also share his audacious plan for mining water on the Moon, along with his concerns regarding humanity’s spread across the solar system. Can we avoid the mistakes made in past eras of exploration and expansion? You’ve got one more chance to win your own asteroid—a small, rubber one—in this week’s What’s Up space trivia contest.

We are joined by the leader of the OSIRIS-REx mission that sampled an asteroid last week. Dante reveals just how brilliantly successful the encounter was, and describes preparations for the journey back to Earth. Space journalist Nancy Atkinson tells us about Orbilander, a mission that would orbit and then descend to Saturn’s moon Enceladus in a search for life. Space headlines from The Downlink and our weekly visit with Chief Scientist Bruce Betts round out this week’s show.

OSIRIS-REx has done it! We have special coverage of the spacecraft’s successful collection of a sample from asteroid Bennu. Then we talk with Jane Greaves, leader of the team that found evidence of phosphine gas in the atmosphere of Venus. Has this put us on the road to discovery of life above that hellish world? Bruce Betts and Mat Kaplan offer a copy of Beyond Earth’s Edge: The Poetry of Spaceflight in the new space trivia contest.

Protecting worlds like Earth and Mars from microscopic invaders carried by human and robot visitors was just one of the scores of topics covered at this year’s Humans to Mars summit. Mat Kaplan moderated a panel featuring planetary scientist and New Horizons mission principal investigator Alan Stern, NASA associate administrator Mike Gold, and NASA planetary protection officer Lisa Pratt. Planetary Society digital editor Jason Davis shares the fascinating 40-year timeline that can be found in the Society’s September equinox edition of The Planetary Report, and Mars shines bright in our What’s Up segment.

A month before the U.S. election Joe Biden's campaign has yet to state its goals for space and NASA. We asked Jeff Foust, one of the best space reporters in the business, to help us piece together a working model of a potential Biden Administration space policy. We comb through the available evidence, combining insights from Biden's history in the Senate, his 8 years as vice president, and current activities in the Democratic House of Representatives and party platform to create a prediction of what might be the same, and what might differ from the Trump Administration's approach to NASA.
