BSV Webinar 0064: A.C. Charania: Space, Defense & the Lunar Opportunity

Balerion General Partner Dan Wallman sits down with Balerion Advisor, Vast Board Member, and Zeno Power SVP of Space Business Development A.C. Charania to discuss lunar infrastructure, commercial space stations, nuclear power in space, and emerging opportunities at the intersection of space and defense.A.C. brings more than two decades of experience across the commercial space sector and government, including leadership roles at Blue Origin, Virgin Orbit, and NASA, where he served as Chief Technologist. Today he works at the center of several key developments shaping the next phase of the space economy: supporting the Balerion investment portfolio, serving on the board of commercial space station company Vast, and leading space market development at Zeno Power, which is building compact nuclear power systems for missions ranging from the seabed to the outer planets.In this conversation, A.C. shares lessons from developing the Blue Moon lunar lander program, insights from inside NASA’s technology portfolio, and his perspective on where the next major opportunities in space will emerge, from lunar infrastructure and commercial LEO stations to power systems and the growing overlap between space and national security.00:00 – Introduction and industry contextDan Wallman opens the webinar, introduces A.C. Charania, and frames the conversation around recent momentum in the space sector and Balerion’s activity.00:40 – A.C. Charania’s background across space and governmentA.C. walks through his career spanning SpaceWorks, Virgin Orbit, Blue Origin, Reliable Robotics, NASA, and now Zeno Power, while also serving as a Balerion advisor.03:34 – Building Blue Origin’s lunar lander effortA.C. reflects on joining Blue Origin at the start of the lunar lander effort and helping mature it from an early concept into a major NASA-funded program.05:30 – Commercial opportunity on the MoonDiscussion of lunar cargo rate, infrastructure utilization, and the role of lunar resources such as water ice in enabling a sustainable cislunar economy.07:28 – Moving from commercial space into NASAA.C. explains what changed when he moved inside NASA, including the agency’s coordination-heavy culture and the challenges of accelerating decision-making.09:15 – First-principles thinking and technology portfolio management at NASAA.C. discusses trying to improve efficiency, focus on metrics, and push NASA’s early-stage technology investments toward clearer outcomes.10:11 – Artemis architecture and the path back to the MoonDan asks about the evolving Artemis architecture, and A.C. explains why the newer plan is more logically sequenced and more competitive.12:11 – Lunar milestones before a human returnA.C. highlights key upcoming lunar demonstrations, cargo landers, propellant transfer work, and the broader buildout of lunar communications and power infrastructure.13:17 – What Zeno Power doesA.C. shifts to his current role at Zeno Power and explains the company’s focus on compact radioisotope power systems for maritime and space applications.14:02 – How radioisotope power worksHe distinguishes Zeno’s systems from fission reactors and explains how decaying isotopes generate heat that can be converted into electricity.15:50 – Zeno’s five- to ten-year visionA.C. describes the long-term goal of scaling production of radioisotope power systems for widespread deployment from the ocean floor to planetary missions.17:52 – Why power sits at the bottom of every tech stackDan and A.C. discuss how compact off-grid power enables distributed systems in both maritime and space environments.18:56 – Vast and the future of commercial LEO destinationsThe conversation turns to commercial space stations, the ISS transition, and why Vast sits at the center of an important shift from government-owned to commercially provided orbital infrastructure.21:54 – What people may underestimate about building space stationsA.C. emphasizes systems engineering, integration, and flight-testing as core challenges, and explains why vertical integration can be an advantage.24:21 – Underappreciated opportunities in the space economySpeaking with his investor hat on, A.C. highlights power systems, thermal control, satellite manufacturing scale, and Golden Dome-related opportunities.27:37 – Advice for founders building space companiesA.C. shares his core advice: stay close to real customer demand, but do not become so narrowly tailored to one customer that you lose the ability to scale.29:31 – Closing remarksDan wraps the conversation and thanks A.C. for joining.
