Ann Druyan wishes you a happy Sagan Day
November 9 would have been our co-founder Carl Sagan’s 88th birthday. His professional and life partner, Ann Druyan, returns with a love story — the love between two people that encompassed the Cosmos and had to be shared. Sarah Al-Ahmed will tell us about two missions to Venus. Sarah, too, was inspired by Dr. Sagan. The theme continues with Planetary Society Chief Scientist Bruce Betts in this week’s What’s Up segment.

Innovate! NASA’s leading-edge fellows share their amazing projects
Mat Kaplan once again hosted the live webcast from the annual NASA Innovative Advanced Concepts or NIAC symposium. He presents a speed dating sample of highlights. How about a Mars habitat grown from mushrooms? A lunar farside radio telescope built by robots? Or a kilometer-long space station launched by a single rocket? We’ll also join Planetary Society chief scientist Bruce Betts for another What’s Up scan of the night sky and more.

Space Policy Edition: The Geopolitics of a Successful SETI Detection
What would nation-states do in response to a signal from an alien intelligence? Would they compete for status and control of the message, or hope to gain some technological advantage from its contents? Or would the world shrug its shoulders and move on? Professor Jason Wright, Director of the Penn State Extraterrestrial Intelligence Center, joins the show to discuss a new paper proposing a more nuanced and positive view of world behavior given a potential SETI detection, and how the most likely message we receive may be more ambiguous than we imagine.

Grounded: The director of the SOFIA flying observatory looks back
The Stratospheric Observatory for Infrared Astronomy (SOFIA) made its last flight on Sept. 30, 2022. Astronomer Margaret Meixner was onboard as the huge telescope built into a 747 aircraft ended its observations of the universe. Margaret joined us earlier that day to celebrate the great successes of this unique instrument and its team.
