Adelaide-based Neumann Space is pioneering a range of new technologies, including using electric, rather than chemical, propulsion for spacecraft. The business believes its "Neumann Drive" has the potential to change the game by making propulsion simpler and paving the way for tech that could effectively "refuel" satellites in space, alongside making deorbiting easier. In this episode, CEO Herve Astier and executive chairman Peter Schultz discuss how they built the business by thinking about existing technology in a new way.
