Sending an SOS to Congress: Save Our Science!

2025 was one of the most consequential years for space policy in modern U.S. history.

In this special year-in-review episode, Planetary Radio takes a deep dive into what happened behind the scenes in U.S. space policy and advocacy as NASA faced unprecedented proposed cuts to its science programs. With nearly half of NASA’s science budget at risk, dozens of missions threatened, and months of leadership uncertainty at the agency, this year became a defining moment for the future of space science.

Sarah Al-Ahmed is joined by Casey Dreier, chief of space policy at The Planetary Society, Jack Kiraly, director of government relations, and Ari Koeppel, an AAAS science & technology policy fellow, to unpack how this crisis unfolded and how scientists, space advocates, and lawmakers responded. Together, they explore how public advocacy helped shift the conversation in Congress.

Plus, in What’s Up, Chief Scientist Bruce Betts explains why stability matters so much for space science and what’s at stake when long-term missions are disrupted.

This is the first of two special year-end episodes. Next week, Planetary Radio will look back at what humanity accomplished in space exploration in 2025, from new missions and discoveries to milestones across our Solar System and beyond.

It was such a delight to feature work by our own Kate Howells in The Planetary Society’s member book club. We keep Kate busy as our public education specialist, but she found time to write about many of her favorite natural satellites in this richly illustrated edition. Join her and book club host Mat Kaplan for a journey taking us from our own Moon, past Europa, Titan, and many more, and out across a galaxy that is no doubt full of worlds circling other worlds.

The Planetary Society’s Kate Howells has written this beautifully illustrated trek among our Solar System’s most intriguing and mysterious moons.

Book Club Edition: MOONS: The Mysteries and Marvels of our Solar System by Kate Howells

Thirty years ago, NASA’s Galileo spacecraft became the first mission to orbit Jupiter, opening a new chapter in our exploration of the outer Solar System. Over eight years around Jupiter, Galileo transformed how we understand Jupiter and its moons, revealing a powerful and dynamic planetary system, uncovering evidence for oceans hidden beneath icy worlds, and reshaping the search for life beyond Earth.

To mark the 30th anniversary of Galileo’s orbital insertion, scientists, engineers, historians, and advocates gathered at the California Institute of Technology for a special symposium: Galileo at 30. In this episode of Planetary Radio, host Sarah Al-Ahmed takes you inside that celebration. You’ll hear how Galileo survived seemingly impossible challenges, how its team adapted when things went wrong, and how its discoveries reshaped planetary science.

You’ll hear from key voices in Galileo’s story, including historian Erik Conway, project manager Bill O’Neil, magnetometer principal investigator Margaret Kivelson, Europa Clipper Project Scientist Bob Pappalardo, and Dragonfly mission Principal Investigator Elizabeth “Zibi” Turtle, along with reflections from many others whose lives and careers were shaped by this remarkable mission.

Together, they tell the story of Galileo not just as a spacecraft, but as a shared human effort, one whose legacy continues to guide exploration today.
