This week on Pathfinder, we welcome back Andy Lapsa, cofounder and CEO of Stoke Space. Stoke has made remarkable strides since Andy's last appearance on the show two years ago. They've grown to over 140 employees and developed innovative full-flow staged combustion cycle engines and reusable upper-stage prototypes. Andy shares his insights on the challenges and progress in creating fully reusable launch vehicles, emphasizing the importance of rapid reusability for reducing costs and increasing availability and reliability.

We dive into Andy's background, including his ten years of experience at Blue Origin and his decision to start Stoke Space to accelerate the pace of innovation. We also discuss:

The unique technical approach of Stoke and the architecture of their first launch vehicle, Nova
The strategic decision to focus on second-stage reusability and how it differentiates Stoke from other providers
Thoughts on the current state of launch and the market potential for multiple providers
The importance of manufacturing and scalability in achieving high-frequency launches
Stoke's proprietary software, Fusion, and its role in optimizing operations

And much more...
