Bruce Betts, Jason Davis, Casey Dreier and Emily Lakdawalla gather with Mat Kaplan for a fascinating and informative Planetary Radio Extra year-in-review roundtable discussion.
Our year-end review features the “best of 2015” lists from Jason Davis, Casey Dreier, Emily Lakdawalla and Bill Nye the Science Guy. What’s Up offers planets, a comet, and a nice prize package for the space trivia contest.
Mat Kaplan sits down with our Director of Advocacy, Casey Dreier, for a discussion of NASA's 2016 budget.
The newly-approved federal budget includes great news for fans of space exploration and development. Texas Congressman John Culberson led the fight for a Europa mission, the SLS rocket, commercial crew and more. He tells us why on this week’s show.
Senior Editor Emily Lakdawalla has returned from the Lunar and Planetary Science Conference in Texas with the latest revelations about our solar system. She shares them in an extended report.
The Beagle 2 Mars lander disappeared after it separated from the Mars Express orbiter on Christmas Day, 2003. Eleven years later, it has been found, partially-deployed on the Martian surface. Longtime Beagle 2 mission leader Mark Sims tells the story.
We’ll visit the Jet Propulsion Lab on its Icy Worlds Day to learn more about spacecraft exploring Ceres, Enceladus and Europa from leaders of these missions.
The just-released budget for the US space agency has much that fans of planetary science can be grateful for, though the news is not all pos.
Robina Shaheen and Mark Thiemens tell us how an ancient Mars meteorite has revealed much about the red planet. Mat holds a tiny fragment of the rock in their UC San Diego lab.

MIT planetary scientist and astrophysicist Sara Seager is on a quest. She wants to find a warm, wet exoplanet with signs of life. It could be Earth 2.0.
It’s terribly hard to find exoplanets that look like our homeworld. The search requires development of astoundingly powerful and precise instruments. That’s the job Debra Fischer and her team have taken on.
Cassini Project Scientist Linda Spilker joins us at the first Starlight Festival in Big Bear Lake, California, and festival MC Andre Bormanis makes a bonus appearance on the show.
Planetary Radio host Mat Kaplan learns why Director of Advocacy Casey Dreier is cautiously optimistic about the budget outlook for planetary science and exploration, so long as Planetary Society members and others keep making their voices heard in the nation's capitol.
