Oldest Bang Since the Big Bang!

Marcia Smith, the founder and editor of Space Policy Online, joins the show and revisits a conversation we had one year ago, recorded just weeks before the second Trump administration took office. That episode, “The Challenges of Change at NASA,” explored the institutional and political roadblocks to radical change at the U.S. space agency.

A lot has happened since that show, including DOGE, mass staff departures, a draconian budget cut proposal, a dramatic shift toward sending humans to Mars, and the rapid departure of 20% of NASA's workforce.

But at the end of the year, much remains the same. The SLS and Orion programs continue unchanged, with funding locked in through 2032. The humans-to-Mars policy has effectively vanished; returning U.S. astronauts to the Moon, to stay, is again centered within civil space policy. NASA's science missions, though still facing a serious budgetary threat, have not gone away.

So, did we see real change at NASA? And to what end? Or was it merely disruption masquerading as change?

Marcia Smith and host Casey Dreier revisit their original analysis and discuss what they got wrong, what they got right, and what surprised them about 2025 in civil space policy.

After DOGE cuts, mass staff departures, and a blink-and-you-missed-it pivot to Mars, how much did NASA actually change in 2025? Space Policy Online founder Marcia Smith returns to assess a turbulent year.

Space Policy Edition: Change for the Sake of Disruption at NASA

As 2025 comes to a close, Planetary Radio looks back on a year that reshaped space exploration, through stunning discoveries, major milestones, unexpected challenges, and the people who carried science forward through it all.

In this episode, Sarah Al-Ahmed, host and producer of Planetary Radio, is joined first by Kate Howells, public education specialist at The Planetary Society, to share results from The Planetary Society’s Best of 2025 campaign and the newly released 2025 Year in Pictures edition of The Planetary Report. They discuss the images, missions, and accomplishments voted on by the global space community, and how space imagery continues to inspire curiosity, connection, and hope. 

Then, Sarah sits down with Mat Kaplan, senior communications advisor, Asa Stahl, science editor, and Ambre Trujillo, digital community manager at The Planetary Society, for a wide-ranging conversation about the defining space exploration stories of 2025. 

The episode closes with Bruce Betts, chief scientist of The Planetary Society, in What’s Up, where he looks ahead to what’s coming in 2026.

Planetary Radio looks back at the biggest space exploration stories of 2025, from stunning images and major missions to hard lessons about how science moves forward. Host Sarah Al-Ahmed is joined by members of The Planetary Society’s communications team to reflect on what defined the year, and what they’re most excited to see in 2026.

Looking back: Space exploration in 2025

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.
