Space Policy Edition: Was the Space Shuttle a policy failure? Dec 01, 2023

Show notes

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.

A City on Mars Nov 08, 2023

Show notes

Can we build permanent human settlements in space? It might be more complex than you think. Kelly and Zach Weinersmith join Planetary Radio this week to discuss their new book, "A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through?" Then Bruce Betts, the chief scientist of The Planetary Society, and host Sarah Al-Ahmed chat about some of the most significant challenges humanity might face as we build habitats beyond Earth.

Space Policy Edition: What went wrong with Mars Sample Return Nov 03, 2023

Show notes

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.
