BSV Webinar 0042: Longshot

Balerion Senior Associate Aidan Daoussis sits down with Longshot Founder & CEO Mike Grace to discuss kinetic launch, radically lower launch costs, and reinventing access to orbit.00:00 – Welcome & introductionsAidan introduces Mike Grace and Longshot, setting the stage for a discussion on fundamentally rethinking space launch economics.01:30 – Mike Grace’s background & Longshot’s originMike traces his path through NASA, startups, and early inspiration from SpaceX and the Ansari X Prize, culminating in founding Longshot.03:30 – The core insight: launch cost as the primary leverWhy lowering the cost of getting mass to orbit reshapes the entire space economy beyond incremental rocket improvements.05:00 – What is kinetic launch? (Plain-English explanation)Ground-based energy systems accelerate payloads before flight, eliminating the need to lift fuel and infrastructure.06:45 – Rockets vs artillery analogyWhy stationary systems are dramatically easier to build than flying ones—and how kinetic launch exploits that asymmetry.08:00 – Energy economics of launchBreaking launch down to electricity costs and why the long-term goal is coupling launch pricing to grid energy prices.10:00 – Baby Bear, Mama Bear, Papa Bear roadmapLongshot’s phased system approach, from MVP competitive with Starship to megaton-scale solar-system infrastructure.12:00 – Why not railguns or centrifuges?Critique of SpinLaunch and magnetic rail systems: unnecessary novelty, material limits, and poor product-market fit.14:30 – Historical precedents: WWII and the 1960s supergunsLessons from the German V-3 and Gerald Bull’s work showing manufacturability and cost advantages.16:00 – Touring the Alameda facilityDiscussion of Longshot’s new hangar and the world’s largest operational gun currently in testing.17:30 – Prototype results & multi-injection systemOver 100 firings of the small prototype; precision timing via controlled gas “pops” rather than valves.19:30 – Scaling to defense and hypersonicsThe current system’s role in hypersonic testing and Department of Defense applications.21:00 – What can (and can’t) be launched kineticallyWhy telecom satellites, solar panels, and orbital infrastructure tolerate high G-forces—and humans do not.23:30 – Orbital insertion & second-stage requirementsWhy a small, simple kick stage is still needed for orbit circularization—but at a fraction of rocket energy.26:00 – Earth vs Moon launch architecturesWhy magnetic rail launch may work better on the Moon, while kinetic gas-based launch dominates on Earth.28:30 – Golden Dome & hypersonic demandMassive DoD tailwinds, missile defense testing, and Longshot’s cost advantage versus traditional rockets.30:00 – Government traction & contract pipelineSBIR funding, MDA discussions, and pursuit of large programs of record.32:30 – Products, not PowerPointWhy owning working hardware accelerates government adoption compared to speculative proposals.35:00 – Deterrence economics vs exquisite weaponsCost-per-capability as the decisive factor in modern defense competition.38:00 – Fixed infrastructure vs mobile missilesVisibility, deterrence value, and why known launch sites can still be strategically valuable.40:00 – Scaling fast with fundingHow quickly Longshot could deploy operational systems with sufficient capital and authorization.42:00 – Two-year path to transformative capabilityTimeline to fielding a system capable of reshaping hypersonics and launch economics.44:00 – Closing reflectionsWhy kinetic launch is a foundational infrastructure play for space, defense, and humanity’s long-term future.44:00 – Deployment scenarios & geographic sitingDiscussion of where kinetic launch systems make sense geographically, including coastal sites, deserts, and allied partner locations.45:30 – Regulatory and safety considerationsFAA, DoD, and airspace coordination challenges; why ground-based systems simplify certification compared to reusable rockets.47:00 – Environmental impact & sustainabilityComparing kinetic launch to traditional rockets in terms of emissions, noise, and environmental footprint.48:30 – Competitive landscape & why Longshot is differentWhy other alternative-launch concepts struggle to scale, and how Longshot’s approach prioritizes manufacturability and physics-first constraints.50:00 – What success looks like in 3–5 yearsDefining success not by launches alone, but by cost-per-kg, cadence, and integration into defense and space supply chains.51:30 – Broader implications for space infrastructureHow ultra-low-cost launch changes satellite design, on-orbit construction, and long-term space industrialization.53:00 – Final reflections on reinventing launchMike summarizes why kinetic launch is an inevitability once economics, energy, and materials are correctly aligned.54:30 – Closing remarksAidan thanks Mike for joining and previews future BSV webinars focused on launch, infrastructure, and deep tech.
