Sophia Space just secured $10 million to turn satellites into supercomputers, moving AI from Earth-bound server farms directly into orbit.
Down here, AI is a resource hog: it guzzles water for cooling and radiates excessive enough heat. Pasadena’s aerospace elite are taking AI off-planet. The solution to the data crisis is found 300 miles up, in the cold, quiet efficiency of orbit.
Sophia Space, a Pasadena-based startup specializing in space-native computing, has closed a $10 million Seed funding round. The round was led by Alpha Funds, KDDI Green Partners Fund, and Unlock Venture Partners.The company is developing an AI-optimized computing infrastructure designed specifically for the harsh orbital environment. The funding will enable the advancement of two technological pillars: a TILE platform and space-native thermal management.This proprietary, passive radiative cooling technology would enable supercomputers to operate without overheating in space. “Sophia Space is pioneering scalable supercomputing in orbit; fueling the emerging space economy, strengthening national defense infrastructure, and helping to save lives on Earth by processing massive volumes of space-generated Earth observation data in real time,” said Dr. Leon Alkalai, Founder and CTO of Sophia Space. “It effectively reduces bandwidth demands and latency, enabling faster, real-time decision-making for time-critical missions, from defense and disaster response to maritime awareness and monitoring vital energy infrastructure,” added Alkalai, who is a former NASA/JPL Fellow. AI’s heat problemComputers generate massive heat. On Earth, fans and liquid cooling are used. In space, there is no air to move heat away. The company is designing ruggedized, “space-native” hardware to survive the vacuum’s brutal radiation and temperature swings. Solving these orbital physics headaches, it will allow power-hungry AI and cloud workloads to finally scale beyond Earth’s atmosphere.“Moving high-performance compute into orbit isn’t just growth. It’s a separator. Our TILE modules, enhanced with patented cooling technology, let us scale AI in ways that are simply unmatched,” added Rob DeMillo, Co-founder and CEO of Sophia Space. Industry giants like SpaceX and Google rely on bulky radiators to cool orbital data centers. Sophia Space — an Nvidia partner — is pivoting to a thin “TILE” architecture. Tech Crunch explained that these modular, meter-wide server racks use a passive heat spreader and integrated solar panels. The design will eliminate active cooling to ensure that 92 percent of the generated power is used directly for processing. To manage this efficiency, the company is developing a software layer to balance workloads across the hardware, with plans to flight-test the system on an Apex Space satellite bus by late 2027.Long-road aheadWith its unique heat-shedding technology, Sophia Space is scaling a modular “TILE” architecture to serve as the brain of the next-generation space economy. “With this Seed round, we’re not just building compute modules,” DeMillo added. “We’re building the infrastructure for the next era of space-based AI and data processing.”Reportedly, the company aims to construct data centers by interlocking thousands of TILE modules by the 2030s. Interestingly, this modular megastructure would function as both a power plant and a processor, delivering 1 MW of computing power to support the growing demands of the space economy.If successful, it would enable AI inference and data processing to occur directly in orbit, thereby reducing latency and bandwidth constraints associated with sending massive datasets back to Earth.It would offer a data-heavy backbone for everything from commercial satellite constellations to critical national defense missions.

U.S. Offers $10 Million Reward for Capture of Tijuana Cartel LeadersThe U.S. State Department is offering a combined reward of up to $10 million for information leading to the arrest or conviction of two brothers, Rene Arzate Garcia and Alfonso Arzate Garcia, leaders within a Tijuana-based cartel. The reward announcement coincides with a new indictment against Rene Arzate Garcia, including charges of conspiracy, narcoterrorism, and providing material support to a designated foreign terrorist organization. The authorities say the brothers are key figures in the Sinaloa Cartel's command structure, controlling a critical trafficking node at the U.S. border.
