Dr. Gurpartap "GP" Sandhoo, a Senior Space Development Agency leader, shares insights on transformative advancements in 2025. He discusses groundbreaking achievements like tracking hypersonic threats with low Earth orbit sensors and the introduction of space-based Link 16 communications for broader operational reach. The conversation also covers the successful demonstration of the first optical space-to-air laser link. Sandhoo emphasizes the importance of speed, adaptability, and emerging technologies as key to future endeavors.

In this discussion, Luke Fisher, CEO of SkyFi, emphasizes the importance of fast and actionable intelligence over just speed in launches. Bradley Cheetham, from Advanced Space, highlights the urgent need for usable capabilities, while Bob Pavelko, from Intuitive Machines, promotes a pragmatic approach using 'minimum viable products.' The panel underscores how the commercial sector is outpacing government efforts, delves into risk tolerance in experimentation, and discusses the integration of commercial and classified systems for national security.

In this episode of Space Minds, host Sandra Erwin sits down with former NASA astronaut and Space Force leader Brig. Gen. Nick Hague for a wide-ranging conversation on how the U.S. Space Force is shaping its culture, training Guardians, and preparing for future conflict in space.Hague reflects on his journey from the International Space Station to the Pentagon, where he now helps oversee operations, readiness, and policy for America’s newest military service. The discussion explores what “test” really means in the Space Force, how risk and speed are balanced, and why continuous learning is essential to maintaining space superiority.

Maj. Gen. Stephen Purdy, a senior U.S. Space Force acquisition leader and SpaceNews Icon Award recipient, talks modernization of software, infrastructure, and commercial integration. He highlights 2025 as a turning point for Space Systems Command. Short takes cover AI adoption, on-orbit servicing and refueling, acquisition reform, and surprising commercial tech shaping military space.

Matt Magaña, President of Space, Defense and National Security at Voyager Technologies, dives into the pivotal Golden Dome initiative, highlighting its significance for U.S. missile defense by 2025. He discusses the challenges posed by hypersonic weapons and advocates for an integrated system-of-systems approach. Magaña shares insights on scaling dual-use technologies, recent acquisitions to boost capabilities, and the importance of AI/ML for future defense strategies. His foresight on the evolving landscape of national security is both riveting and essential.

In this episode of Space Minds, former NASA commercial space division chief Phil McAlister sits down with host David Ariosto for a wide-ranging conversation about the future of human spaceflight, NASA’s internal culture, and the explosive growth of the commercial space sector.McAlister spent nearly 20 years inside NASA, helping spearhead programs like Commercial Crew and COTS, which paved the way for SpaceX, Blue Origin, Rocket Lab, and a new era of public-private partnerships. He shares stories about internal resistance, political battles, and what it took to shift NASA away from cost-plus contracting after decades of inertia.We also dive into:• Whether the U.S. is really in a “space race” with China• Why the moon’s South Pole may not be first-come, first-served• The sustainability crisis facing SLS, Orion, and Artemis• The role of commercial companies in deep space—not just LEO• How Starship, New Glenn, and private human spaceflight change everything• Whether NASA is destined to become more like the FAA• What the next 50 years in space might actually look like

In this episode of Space Minds, Senior Staff Writer Jeff Foust moderates a panel at the Johns Hopkins University Bloomberg Center, the next installment of the Center’s Discovery Series.The panel brings together leaders from Astrobotic, Apex, Johns Hopkins APL and Stoke Space to explore how ideas once confined to the pages of science fiction are rapidly becoming reality. From commercial lunar landers and factory-scale satellite production to nuclear-powered rotorcraft bound for Titan and fully reusable rockets designed to fly daily, the space industry is undergoing a transformative moment.The panel discusses the technologies driving this surge—lower-cost launch, advanced autonomy, shrinking spacecraft, and the rise of a vibrant commercial ecosystem. They also examine the future of lunar infrastructure, in-orbit manufacturing, national security needs, and the growing competitive pressure from China. It’s a wide-ranging conversation about innovation, challenges, and the new frontiers emerging as space becomes more accessible than ever.

In this engaging discussion, Marshall Smith, CEO of Starlab Space and a former NASA engineer with extensive experience in spacecraft programs, shares his vision for the future of commercial space stations. He highlights the shift towards independent commercial capabilities and how market demand has surged, with over half of Starlab's capacity already reserved. Smith also emphasizes the importance of continuous human presence in space, the role of AI in operations, and innovative design strategies to make space more habitable—setting the stage for a new era of exploration and manufacturing.

In this episode of Space Minds, host David Ariosto speaks with Jim Bridenstine, former NASA Administrator and U.S. Congressman, who oversaw the launch of the Artemis program—America’s renewed effort to return astronauts to the Moon.Now Managing Partner of the Artemis Group, Bridenstine discusses the intersection of politics, policy, and innovation shaping the modern space race. From government shutdowns and funding instability to U.S.-China competition and the future of lunar commercialization, he shares candid insights on why America’s leadership in space depends on sustaining investment, fostering commercial partnerships, and inspiring a new generation through science and exploration.
