Radiolab helps name a quasi-moon of Venus
2024/04/10
Info (Show/Hide)
Sometimes, misunderstandings can spark beautiful adventures. This week on Planetary Radio, we explore the story behind the naming of Zoozve, a quasi-moon of Venus, with Latif Nasser, co-host of Radiolab. He shares how a typo on a space poster led the Radiolab team on an epic quest to convince the International Astronomical Union to name this quirky space object. Then, Bruce Betts, our chief scientist, pops in for What's Up and a discussion of some of the things asteroid hunters have found lurking in our Solar System.

Space Policy Edition: Real and Acceptable Reasons for Space Exploration
2024/04/05
Info (Show/Hide)
Former NASA Administrator Mike Griffin joins the Space Policy Edition to discuss his notable 2007 speech outlining the tension between so-called “real” and “acceptable” reasons for space exploration.
“Acceptable” reasons for space exploration are logical, policy-friendly justifications such as workforce development, technology spinoffs, and STEM engagement. They are quantifiable and dispassionate — the Vulcans of arguments.
However, Griffin argues that the essence of humanity's drive to explore space is the “real” reasons, which are intuitive, emotional, and grand. They have value but are hard to quantify. These include the innate human desire for competitiveness, curiosity, and the urge to leave lasting legacies through monumental achievements.
Why do we have this dichotomy? What in the system itself prefers acceptable reasons over real reasons? And how can we leverage the relative strengths of both systems to be better space advocates?

Space Policy Edition: The ahistorical era of commercial lunar exploration
2024/03/01
Info (Show/Hide)
The successful landing of IM-1 on the Moon ushered in a new era of commercial lunar exploration, one that has little to no historical precedent. The future, still highly uncertain, is rich with promise for what commercial payload deliveries can provide. There will be new and more frequent science opportunities, lower-cost access for national and non-state actors, and, potentially, a path to a sustainable presence on the lunar surface. Dr. Matt Shindell, science historian and curator of the planetary exploration collection at the Smithsonian Institution, joins the show to discuss the unique historical moment we find ourselves in, and how planetary exploration has evolved and could continue to evolve on and around the Moon.

Space Policy Edition: Space isn’t black — it’s grey
2024/02/02
Info (Show/Hide)
It’s a policy paper episode! Laura Delgado López joins the show to break down “Clearing the Fog: The Grey Zones of Space Governance” by Jessica West and Jordan Miller. Grey zones are harmful or disruptive space activities that fall short of provoking a military response — ideally. But the ambiguity, by its nature, could generate unplanned escalation and conflict.
What are these grey zones, and why do they exist? What are their consequences to humanity, even for those in nations not actively pursuing spaceflight? And by what means can we reduce the uncertainty and, therefore the risk to space operations at Earth and beyond?
Laura Delgado López has worked in space policy in the Washington, D.C., area for nearly 15 years and is currently a visiting fellow with the Americas Program at the Center for Strategic and International Studies (CSIS), where she researches and writes on international space cooperation in Latin America. She selected this episode’s paper, which can be accessed for free at the Centre for International Governance Innovation’s website .

Space Policy Edition: India’s growing space ambitions
2024/01/05
Info (Show/Hide)
The history of India’s space program is, in many ways, the inverse of that of the US and Russia. While the two superpowers were outpacing each other in space spectaculars in their early decades, India — which began its space program around the same time in 1963 — prioritized practical programs by developing its own launch capability and launching satellites for weather, communications, and regional positioning systems. It is only in the 21st century that India began embracing the more symbolic feats of spaceflight, first with its launches of robotic spacecraft, including the Chandrayaan series and the Mars Orbiter Mission, and now by establishing its own human spaceflight program.
Buoyed by the success of Chandrayaan-3, as well as recognizing increasing competition with China, Prime Minister Narendra Modi announced ambitious plans for Indian space stations and lunar missions in the coming decades.
UK-based space writer Gurbir Singh, who literally wrote the book on the Indian space program, aptly titled The Indian Space Programme: India’s Incredible Journey from the Third World towards the First, joins the show to help us understand the history and motivations behind these achievements and India’s growing ambitions in space.

Space Policy Edition: What went wrong with Mars Sample Return
2023/11/03
Info (Show/Hide)
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.
