Guest: José Mariano López Urdiales, CEO and Founder of Zero 2 Infinity

The Cosmic Scoop:
In this remarkably candid episode, José Mariano López Urdiales presents a compelling case for why balloon-assisted launches might be the only economically viable solution for small satellite deployment.
Drawing from 15 years of experience with Zero 2 Infinity, José breaks down why conventional micro launchers face fundamental economic challenges, from capital-intensive launch sites to the physics of dense lower atmosphere.
He explains how launching from 25km altitude could eliminate up to 70% of conventional launch costs while offering a refreshingly honest perspective on the challenges of innovating in Europe's space sector and why copying American rocket designs isn't the answer.
Quotable Insights:
1. "Developing a micro launcher traditionally needs a couple hundred million dollars. We believe with a balloon-assisted launcher, it's in the ballpark of 120 million Euro - including four orbital trials."

2. "Nobody explains it like this - they just say 'because we're so innovative' or whatever. I don't know. I'm going to tell you how it really works."

3. "The only kind of micro launcher that can be viable is balloon-based. But nobody's actually developing it - we got to a certain point, but we're lacking funding."

4 "You don't win by copying. That's not how the V2 appeared, and Starship is super interesting because it's very, very different."
