This outstanding novella, “To Be Taught, If Fortunate” by award-winning science fiction author Becky Chambers, is a passionate argument for the human exploration of space and the wonders we will find there. Kirkus Reviews calls it, “An extraordinary picture of humanity among the stars.” Join host Mat Kaplan for a conversation with Becky in which her personal enthusiasm for space science matches that of her four wandering explorers. The very alien lifeforms they discover amplify their own, very human failings and triumphs. Questions submitted by The Planetary Society’s members were a valuable contribution to this live event presented in our member community.

Saturn's moon Titan is one of the most Earth-like worlds in our Solar System, with a dense nitrogen atmosphere, weather cycles, methane rivers, and vast organic dune fields. It also happens to be the perfect place to fly a drone. NASA's Dragonfly mission is doing exactly that, sending a car-sized, nuclear-powered rotorcraft to explore Titan's surface starting in 2034. With just two years until launch, the team is deep in the work of making it happen.

This week, we're joined by two members of the Dragonfly team from the Johns Hopkins Applied Physics Laboratory. Felipe Ruiz is the mission's lead rotor engineer and mechanical implementation lead, responsible for designing the eight-rotor system that will carry Dragonfly across Titan's skies. Zibi Turtle is the mission's principal investigator, a planetary scientist whose career has spanned missions from Galileo to Cassini to Europa Clipper.

Together, they walk us through the engineering challenges of flying a thousand-kilogram rotorcraft in an alien atmosphere, how the team is testing and validating the design here on Earth, and what the spacecraft's instruments will look for on Titan's surface.

Then Bruce Betts, our chief scientist, joins us for What's Up, where we pay tribute to the Ingenuity Mars helicopter and the legacy of the first powered, controlled flight on another world.

Between budget battles, proposed grant rule changes, and an exploding Blue Origin rocket, there's a lot to cover in U.S. space policy right now. Jack Kiraly, The Planetary Society's director of government relations, joins host Sarah Al-Ahmed to walk through a cascade of developments affecting NASA and the broader U.S. science community, including a proposed rule change at the Office of Management and Budget that would hand control of federal research grant decisions to political appointees, bypassing the peer review process that has underpinned U.S. science for decades. Kiraly also discusses a major reorganization at NASA, a new competition for the management of the Jet Propulsion Laboratory, the fallout from the New Glenn explosion, and what it means for the future of Artemis.

Plus, in What's Up, the names of the Artemis III crew are revealed.
