Aetherflux, a new startup founded by Robinhood co-founder Baiju Bhatt, has emerged from stealth mode with plans to develop space-based solar power technology. The company aims to unlock this untapped energy source, which has been studied for decades but hasn't yet been realized commercially. Meanwhile, venture capital firm Interlagos, established by former SpaceX leaders, is seeking to raise $550 million for its first fund, focusing on hard tech investments. These developments highlight growing interest and investment in the commercialization of space technologies.
