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 c

Episode Summary

Executive Summary: This episode centers on U.S. space policy at the end of FY2018, urging listeners to advocate on NASA funding and congressional engagement, while featuring a deep review of the National Academies’ midterm assessment of the planetary science decadal survey. Casey Dreyer and Louise Proctor explain how NASA has largely met decadal priorities despite budget turmoil, but major concerns remain over Discovery/New Frontiers cadence, ocean worlds process changes, Europa lander prioritization, Uranus/Neptune studies, and the future of Mars exploration beyond sample return.

Main Topics: Planetary Society advocacy and member engagement: The hosts promote membership, congressional visits, and the free Space Advocacy 101 course as practical ways for listeners to influence space policy and support the organization’s work. Fiscal year-end budget and shutdown risk: The conversation warns that Congress has very little time to pass a budget before the fiscal year ends, raising the likelihood of a continuing resolution and possible disruption to NASA and planetary science funding. Why decadal surveys matter: Casey Dreyer explains the National Academies decadal process as a central, respected mechanism for setting planetary science priorities, balancing community consensus, NASA execution, and congressional decision-making. Midterm review of the planetary science decadal survey: Louise Proctor outlines the new National Academies report, concluding NASA has broadly performed well on decadal recommendations despite difficult funding conditions, while identifying areas needing correction or flexibility. Mission-class priorities: Discovery, New Frontiers, and flagships: The discussion debates how NASA balanced small, medium, and flagship missions; the report defends some flagship progress but acknowledges slower-than-planned cadence for smaller mission lines. Mars program status and sample return architecture: A bonus section reviews the Mars program, warning it has become too dependent on Mars 2020 and sample return without a broader long-term exploration framework or refreshed telecom infrastructure. Europa, ocean worlds, and future outer solar system strategy: The report grapples with strong congressional enthusiasm for Europa lander concepts, the addition of ocean-world mission concepts to New Frontiers, and the need for more aligned study processes for future ice-giant missions.

Key Arguments: Congress and citizens should actively support space policy because NASA budget decisions are being made under severe time pressure and can directly affect science continuity. The decadal survey is an unusually effective policy tool because it converts broad community consensus into a durable, fundable NASA roadmap. NASA has generally respected the decadal survey despite starting from worse-than-expected budget conditions, especially in research and analysis and technology development. Large flagship missions can be scientifically transformative and politically sustaining, but they must be balanced against smaller missions and workforce continuity. Ocean worlds and Europa developments justified some course correction, but the committee argued that new mission concepts should still go through community-based decadal processes. The Mars program needs an integrated long-term plan; sample return alone is not a full program and aging orbital relay assets create real risk. For the next decadal, NASA should do more precursor studies earlier so future mission concepts are vetted before the survey begins. The committee declined to elevate the Europa lander immediately because it was outside the statement of task and not part of the original decadal priorities.

Data Points: Federal fiscal year deadline: ~11 working days after Labor Day - Time available for Congress to pass a budget before the fiscal year ends House of Representatives seats up for election: 435 - Explained as part of the midterm election context Senate seats up for election: 1/3 of the chamber - Also part of the midterm election context Decadal survey coverage period: 2013-2022 - The planetary science decadal survey under review Midterm point of the decadal: About halfway through the 10-year period - Reason for the National Academies review Discovery mission cadence recommendation: About one every 24 months - Described in the decadal survey and referenced in the review R&A budget increase target: 5% above 2011 level plus 1.5% above inflation - Recommendation for research and analysis funding in the decadal Current R&A funding increase: About 30% above 2011 level - NASA had exceeded the decadal’s R&A recommendation Technology development recommendation: 6–8% of NASA budget annually - Decadal recommendation for technology investment Mars program missions in pipeline: 1 major mission (Mars 2020) - Used to argue the Mars program lacks a broader long-term architecture NASA orbiter age at Mars: MAVEN is the only U.S. orbiter less than 12 years old - Illustrates fragility of Mars telecom/orbital infrastructure Lunar and Planetary Institute age: 50 years - Louise Proctor describes the institution’s history Lunar and Planetary Science Conference age: 50th anniversary upcoming - Highlighting the institution’s role in planetary science New Frontiers mission class: Approximately billion-dollar class missions - Used to distinguish mission sizes in the decadal framework Flagship missions discussed: Mars sample return, Europa/Europa Clipper, Uranus/Neptune mission - High-priority large missions in the decadal and review

Pivotal Quotes: "This decade has been one of the most important and scientifically productive periods ever in the history of planetary science." — Louise Proctor: Opening framing of the midterm report’s assessment of the planetary science decade "If you want to unburden your conscience, join the Planetary Society, support this program, and other work we do." — Casey Dreyer: Appeal for membership and support during the advocacy segment "We think that it was NASA is doing extremely well." — Louise Proctor: Her headline conclusion on NASA’s response to the decadal survey despite budget constraints

Implications: Listeners are urged to act now on budgets and advocacy, while the science community gets reassurance that decadal surveys still shape NASA effectively. But future progress depends on better mission planning, stronger Mars infrastructure, and keeping new discoveries aligned with community consensus.
