Space Policy Edition: Space isn’t black — it’s grey

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.Discover more at: https://www.planetary.org/planetary-radio/grey-zones-in-space-governance See omnystudio.com/listener for privacy information.

Space Policy Edition: India’s growing space ambitions

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.

Space Policy Edition: What went wrong with Mars Sample Return

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.

Space Policy Edition: Why are outer planets missions so expensive?

It's the 50th anniversary of Pioneer 10, the first spacecraft to the outer planets. Pioneers 10 and 11 were scrappy, low-cost endeavors that blazed the path for future exploration. But the future has been expensive: outer planets missions are some of the priciest planetary probes in history. Can we get back to a pioneering spirit and increase the frequency of outer planet exploration? To find out, we talk with Mark Wolverton, author of “The Depths of Space: The Story of the Pioneer Probes,” and Scott Bolton, principal investigator for Juno, the most affordable Jupiter mission in decades. Casey and Mat also discuss the dynamic and tragic situation in Ukraine, and its implications for space.

Space Policy Edition: Should the U.S. be in a space race with China?

China's space program notched an impressive "first" last month when its Chang'e 4 spacecraft landed on the far side of the Moon. The U.S. space program, in contrast, was in the midst of an extended shutdown. Some observers expect China's growing space capability and lunar ambitions to trigger a new space race. Not Dr. Roger Handberg, Professor of Political Science at the University of Central Florida. He discusses how the current geopolitical situation differs from the Cold War standoff between two superpowers, and how we shouldn't expect dollars to flow back to the U.S. space program as a consequence of China's space successes. Cooperation, or even friendly competition, is a much more likely outcome than a new space race.

Space Policy Edition: How NASA Came to Be

Happy 60th, NASA. In celebration of the space agency’s birthday, we do the audio equivalent of pulling out NASA’s baby book and explore its origin story. Though legislation creating the space agency developed in the wake of Sputnik, it was built upon a rapidly changing relationship of the government to fundamental research and development in the decade before. We follow the threads of what makes NASA NASA, as well as how, in its early years, NASA looked quite different than the agency we know today.  We also discuss the current bill that partially funds the U.S. government and provides temporary funding for NASA and other agencies through December of 2018.

Space Policy Edition: Did NASA Ace its Midterms? With Special Guest Louise Prockter

We talk with planetary scientist and Lunar and Planetary Institute Director Louise Prockter, who co-led creation of a new report evaluating the performance of NASA's planetary science division. This comes five years after the release of the influential decadal survey. Given the massive budget cuts over the past few years, how did NASA do? Where do these reports come from and who puts them together? Why are they important? All will be answered in this month’s SPE!  We also look into the report-within-a-report on the status of the robotic Mars Exploration Program, and find some recommendations that appear to have been inspired by a 2017 Planetary Society report.
