Balerion Principal Aidan Daoussis sits down with Bryan Mazor, Co-Founder & CTO of Source Energy, to discuss industrializing solar power for space. Source is developing lower-cost, rapidly manufacturable solar arrays for spacecraft, applying lessons from SpaceX and terrestrial solar manufacturing to increase the availability of power in orbit. The conversation covers Source’s manufacturing strategy, space-rated solar technology, scaling toward megawatt production, and the company’s longer-term vision of becoming an energy provider for space.
