Author Frank White has interviewed well over 100 astronauts. Almost all of them report the sense of awe they experienced as they looked down or back at Earth, and how deeply this has affected their understanding and appreciation of our planet and the Cosmos. It’s what author Frank White calls The Overview Effect. Frank joined Planetary Society Senior Communications Adviser Mat Kaplan for a deep conversation about the ideas he shares in his book of the same name, now in its fourth edition. Here’s a great introduction to the Universe-spanning yet very personal ideas Frank has shared.

Book Club Edition: Exploring the Overview Effect with Frank White

Artemis II is about more than getting four humans to the Moon and back. It's an opportunity to gather data on human health in deep space that we haven’t had in over 50 years.

This week, we’re joined by Steve Platts, chief scientist of NASA's Human Research Program, who walks us through the suite of human health experiments flying aboard Artemis II, from the ARCHER wearable sensors tracking crew health and team dynamics, to dry saliva swabs measuring stress hormones. Then Casey Dreier, chief of space policy at The Planetary Society, helps us make sense of NASA's Ignition Day, a major press event held on March 24 in which the agency unveiled sweeping changes to its lunar exploration plans and beyond.

And we close with Bruce Betts, chief scientist of The Planetary Society, in our weekly What's Up, where we explore one of the stranger phenomena in human spaceflight, the flashes of light astronauts sometimes see when cosmic rays pass through their eyes.

Join us for an awe-inspiring conversation with astrobiologist and astronomer Caleb Scharf as he eloquently makes the case for "dispersal," the nearly inevitable advance of life and humanity across our solar neighborhood.  From the book: "The idea of Dispersal is one where the sheer scale and scope of life’s future extension into the solar system profoundly changes things: not because of some new (and unlikely) cultural enlightenment from within but because of what the enormous expanse of space will do to dilute and change our species and all others.” Adam Frank says of the book, “If we can make it through the many crises of the next century, then the Solar System and the stars beyond await us. In The Giant Leap, Caleb Scharf demonstrates how becoming a true space-faring species is more than just humanity’s future.”

Humanity is going back to the Moon, and Europe is already playing a critical role in making it happen. This week, Planetary Radio brings you voices straight from the 18th European Space Conference in Brussels, Belgium, where more than 2,000 of the world’s top space leaders gathered to shape the future of European space exploration.

We begin with conference co-organizer Tomas Dimitrov of Logos and Business Bridge Europe, who sets the stage for the conversations ahead. From there, we hear from European Commissioner for Defence and Space Andrius Kubilius, ESA Director General Josef Aschbacher, French Minister Delegate for European Affairs Benjamin Haddad, and Germany’s Federal Space Minister Dorothee Bär.

We also take you inside the Moonlight Initiative panel, bringing you the full conversation as scientists and engineers from ESA, NASA, and industry lay out their vision for building GPS and communications infrastructure around the Moon, and wrestle with what it will really take to support a permanent human presence there.

Then, Planetary Society Chief Scientist Bruce Betts joins us for What’s Up to tackle one of the most fascinating and unexpected challenges of lunar exploration: what time is it on the Moon?
