Space Policy Edition: The Moon-to-Mars Strategy, with Dr. Scott Pace

How spacefaring nations prioritize funding can be just as important, if not more so, than the capabilities of the commercial sector, says Dr. Mary Lynne Dittmar, President and CEO of the Coalition for Deep Space Exploration. She joins the show to talk how these complement each other, and why the SLS

Episode Summary

Executive Summary: The episode centers on a Space Policy Edition interview with Scott Pace about the National Space Council’s strategy for deep space exploration. Pace argues that lunar return, Mars, and commercialization should be framed as enduring national interests, not one-off missions, with a whole-of-government and public-private approach that advances U.S. security, diplomacy, and economic goals.

Main Topics: National Space Council strategy and whole-of-government policy: Pace explains that A New Era for Deep Space Exploration and Development is meant to unify NASA, commerce, defense, diplomacy, and other agencies around a coherent long-term space strategy. Sustainability as policy, economic, and technical durability: The discussion emphasizes that sustainable space policy means aligning programs with enduring national interests so they persist across administrations, budgets, and political cycles. Commercialization and space resource utilization: The show explores NASA’s lunar-sample buying announcement and the broader legal/policy precedent for owning and trading resources extracted from celestial bodies without claiming sovereignty. Geopolitics, competition, and norms in space: Pace contrasts today’s environment with the Cold War, arguing that U.S. leadership matters because rules are set by those who show up, especially as China and Russia shape shared domains. Low Earth orbit commercialization and post-ISS future: The interview discusses how LEO can evolve toward a more commercial ecosystem with multiple platforms, private buyers/sellers, and reduced dependence on a single government-owned station. Moon-to-Mars as an expanding sphere of human activity: Rather than flags-and-footprints missions, Pace frames exploration as a continuous expansion of human presence that feeds back into LEO and forward to Mars.

Key Arguments: Space policy should be treated as a whole-of-government issue, not just an NASA program, because it intersects with commerce, defense, energy, transportation, and diplomacy. The strategy document does not create major new policy; it articulates and connects existing directives into a coherent narrative for deep space exploration and development. Sustainability is primarily political and economic: programs must align with enduring national interests so they survive changes in administration and Congress. Commercial and international partnerships are now central because today’s globalized, democratized space environment differs from the 1960s Cold War context. The U.S. should establish norms and legal certainty for space resource extraction so investors and companies can confidently pursue lunar and other off-world activities. NASA’s lunar sample purchase is less about the price and more about creating precedent that collected resources can be owned and sold under U.S. law. Low Earth orbit commercialization, lunar sustainment, and Mars exploration can proceed in parallel rather than as strictly sequential prerequisites. Human spaceflight should be viewed as a continuing national activity, not a one-time destination mission, because lasting value comes from routine presence and capability. The government should spearhead exploration while transitioning feasible operational functions to the private sector whenever possible. U.S. leadership in space is justified not by romanticism but by national interests: security, diplomacy, economic growth, and shared norms in a strategic domain.

Data Points: Strategy document title: A New Era for Deep Space Exploration and Development - National Space Council report released in July and discussed throughout the interview. NASA lunar sample payment: Upwards of $100,000 - Administrator Bridenstine’s announcement about buying lunar soil from a commercial provider. Maximum sample mass: Up to 500 grams - NASA’s proposed purchase amount for lunar material. Front-end payment structure: About 80% upon delivery - Casey Dreyer explains the contract structure for sample acquisition and transfer of ownership. Relevant law: H.R. 2262, Commercial Space Launch Competitiveness Act - U.S. law cited as the domestic framework for space resource rights without sovereignty claims. Year of law: 2015 - The Commercial Space Launch Competitiveness Act passed in 2015 and was signed into law then. Space Policy Directive 1: SPD-1 - Directed NASA toward a moon-to-Mars program with commercial and international partners. Space Policy Directive 2: SPD-2 - Referenced as part of streamlining regulation affecting commercial space industry. Space Policy Directive 4: SPD-4 - Referenced in the context of the changed security environment and creation of the Space Force. Space Policy Directive 5: SPD-5 - Cited as establishing principles for space systems and cybersecurity.

Pivotal Quotes: "Space activities by the United States are reflection of our values." — Scott Pace: Pace explains that space policy serves national interests and expresses American values, not just space enthusiasm. "This is not about flags and footprints. This is not about single-point destinations." — Scott Pace: He frames exploration as an ongoing, sustainable human activity rather than a one-off mission. "The rules are made by the people who show up." — Scott Pace: Pace describes why U.S. presence is needed to shape norms and standards in the space domain.

Implications: The episode suggests the next phase of space policy will hinge on legal certainty, public-private collaboration, and durable national framing. For industry and agencies, that means building systems that can outlast politics and support a sustained lunar and Mars economy.
