Planetary Radio: Space Exploration, Astronomy And Science

Sometimes, when you want to learn more about other worlds, all you have to do is step out your door. Mat Kaplan, Planetary Radio's creator and former host, takes us on an adventure with planetary geologist Kirby Runyon as they tour New Mexico, U.S.'s varied geology and compare it to other worlds. They'll explore the dunes of White Sands National Park, the Mars-like geology of Kilbourne Hole, and the rocks in the Carrizozo Lava flow. Then Bruce Betts, the chief scientist of The Planetary Society, and host Sarah Al-Ahmed discuss the most otherworldly places they've been in this week's What's Up.

Was the Space Shuttle a successful program? In many ways, yes: it endured for 30 years, launched hundreds of astronauts into space, and built the International Space Station. But, according to the goals of lower costs, rapid reusability, and reliability NASA stated at its conception, the Space Shuttle program was a failure. In this new recurring feature on SPE, Jack and Casey read through a classic paper in space policy and discuss its arguments, its conclusions, and whether the paper stands up to this day. Read along with us and suggest future episodes in our Planetary Society online member community.

NASA’s Mars Sample Return mission was supposed to be lean, fast, and focused — no extra science instruments, no dedicated communications systems, and launching in 2026. But the effort has foundered under its own complexity and mismanagement. MSR’s total cost is likely to double to $10 billion or more and not launch until 2030 at the earliest. This month’s guest, Orlando Figueroa, chaired an independent review board which recently evaluated this project and identified management failures, unexpected design complexities, and external events such as the war in Ukraine as contributing to MSR’s difficulties. We review the board’s conclusions and recommendations for how NASA can fix MSR’s problems and ensure a successful return of the samples already selected by the Perseverance rover.
