This was honestly one of the most fascinating interviews I did for this entire series. Walter Ballheimer founded Reflex Aerospace on a bold idea: the biggest problem in the satellite industry isn't getting to space, it's how long it takes. His Berlin-based company builds high-performance satellites in 12 to 18 months, when the rest of the industry needs three to five years. He's genuinely one of the most clear-sighted and original thinkers in the European space sector. Don't miss this episode. From the shifting balance between commercial and defence demand, to what it took to close the largest Series A in European space tech history, Walter gives a frank and fascinating account of what it means to build a hardware company in the New Space era. He makes the case that satellites are already the invisible backbone of modern life and that as autonomous vehicles, rural connectivity, and defence systems grow more dependent on them, the race to renew them faster will never stop. He also has encouraging things to say about world peace... Hosted on Acast. See acast.com/privacy for more information.

Rockets and satellites get the headlines. But what makes them work? Here are five technologies you've probably never heard of, but they're set to have a big impact on how rockets work and, even, on your electricity bill. We'll hear from the founders of companies working on: the pressure vessels inside every rocket and satellite; a green propellant to replace hydrazine, which can be stored for ten years and restarted in under thirty seconds; the aerospike engine, theoretically superior for sixty years and never yet demonstrated in flight; onboard software that lets satellites decide for themselves what to photograph; satellite data that helps power lines carry more electricity. Five technologies. None of them famous. All of them essential. Hosted on Acast. See acast.com/privacy for more information.
Tomas Jonsson leads the Cassini team at the European Commission's Directorate-General for Defence Industry and Space. It's the EU's space entrepreneurship programme. He describes how Europe's space sector has changed since 2019, with many more companies, real commercial growth and significant private investment. He also talks about the careers the sector offers beyond engineering, and about how companies in Poland, the Czech Republic, Scandinavia and the EU's smaller countries are catching up to the traditional big space economies of Germany, Italy and France.

AIKO founder Lorenzo Feruglio explains how automation lets satellites make their own decisions, reducing waste and boosting profits (because right now only 10% of the data gathered by a satellite is monetised). An interview about software, artificial intelligence and...fixing a problem that less original thinkers didn't even know existed. Hosted on Acast. See acast.com/privacy for more information.
Europe's space investment hit a record €1.4 billion in 2025. The first half of 2026 already surpassed that amount. We look at the grants, equity, venture debt and, for the first time, commercial bank lending pushing space up the financial agenda. You'll hear from venutre capital investors at Warsaw's OTB Ventures and the European Investment Fund, bankers at the European Investment Bank, and the European Space Policy Institute analyst who tracks where the money goes. Sateliot founder Jaume Sanpera explains why an EU loan is "much more than money". He also names the financial layer Europe needs to build next. Hosted on Acast.

Space is Europe's "invisible infrastructure". Giancarlo Granero, who leads on the space economy at the European Commission, explains how the European Union's Cassini initiative turned €200 million into a venture ecosystem that raised €1 billion last year.
