Relentless What It Takes To Build A Self-Sustaining City On Mars | Saurav Shroff, Starpath
Oct 21, 2025
Saurav Shroff, co-founder and CEO of StarPath, is on a mission to make Mars habitable with low-cost rovers and solar tech. He discusses the innovative production of methane and oxygen from Martian resources for sustainable fuel. Shroff contrasts expensive NASA rovers with StarPath's affordable models and highlights the challenges of mass solar panel production. He also dives into the philosophical implications of colonizing Mars and frames it as an exhilarating new market. Expect rapid prototyping strategies and a vision of a million-inhabitant Martian city!

Episode notes
Two Machines That Enable Mars Cities
- Two machines are required to make Mars habitable: a fully reusable rocket and a rocket-propellant plant on Mars.
- The propellant plant will consume ~90–95% of a Martian city's energy, making it the city's core engine.
Mars Fuel Is Simple Chemistry, Big Energy
- Rocket fuel on Mars is made by extracting water from regolith, splitting it, and combining H2 with CO2 to make methane and oxygen.
- The process is chemistry-simple but energy-intensive, so power, processing plants, and mining rovers are the three required machines.
Vertical Integration When Suppliers Price Gouge
- When a supply chain item is far too expensive, vertically integrate to reduce unit cost and secure production.
- StarPath built its own solar-cell production after vendor quotes were 10–20× higher than target.
