Should policymakers spend more time looking — really looking — at the Moon? Chris Cokinos thinks so. He is the author of the new book, Still As Bright: An Illuminating History of the Moon, from Antiquity to Tomorrow, which explores the role of our nearest celestial neighbor in culture, art, and our dreams of space exploration over the course of human history. It’s about the power of looking and seeing something beyond what you’d expect. But the conversation goes beyond that. We discuss the role of the sublime in our everyday lives, how to find beauty in the quotidian, the role of language in conveying the beauty and power of space, and even why he thinks landing cremains on the Moon is disrespectful.

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?

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.

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.

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.See omnystudio.com/listener for privacy information.

NASA's Dragonfly mission to Saturn's moon Titan has been authorized to proceed with work on final mission design and fabrication, known as Phase C. This week on Planetary Radio, we get an update on the mission's progress and new timeline. You'll hear from Bobby Braun, head of the Johns Hopkins Applied Physics Lab's Space Exploration Sector, Elizabeth (Zibi) Turtle, the principal investigator for Dragonfly, and Ken Hibbard, mission systems engineer for the spacecraft. If that doesn't convince you that Dragonfly is one of the most epic things humanity has attempted to date, stick around for What's Up with Bruce Betts as he shares even more reasons for us to explore Titan.

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.
