This week on Pathfinder, we’re ready to kick off 2025 with our first episode back from a brief holiday hiatus. Joining us is Stefan Powell, co-founder and CEO of Dawn Aerospace—a company focused on building scalable, sustainable space transportation solutions. After cutting their teeth with an in-space propulsion business, Dawn is now pushing the boundaries with Aurora, a rocket-powered plane that recently breaking the sound barrier (or Mach 1).

In this episode, we explore:

From Student Rocket Club to Thriving Venture: Stefan’s background and how his early rocketry experiences shaped Dawn’s mission.
Satellite Propulsion: Why Dawn’s safer, scalable alternatives to traditional satellite fuel are gaining traction in the market—and how they enable near-term revenue.
Aurora’s Breakthrough Flight: Hitting Mach 1.1, testing supersonic aerodynamics, and the path toward suborbital flight capabilities.
Hypersonics & Beyond: Why government R&D and military programs are pouring billions into hypersonics research—and how Dawn plans to help solve the “access-to-test-time” gap.
Aircraft-Like Space Access: Dawn’s long-term vision for truly rapid, reusable, runway-based vehicles that could revolutionize launch operations.
Building for the Future, One Step at a Time: How Stefan thinks about scaling, capital efficiency, and bridging near-term commercial opportunities with an ambitious roadmap.

…and much, more.
