The race to build the infrastructure powering the next generation of the space economy has taken another significant step forward. Sophia Space Inc., a portfolio company of Mandala Space Ventures, has announced the issuance of U.S. Patent No. 12,679,564 for its groundbreaking Space-Based Data Centers architecture, marking a major milestone in the commercialization of orbital computing technologies.
The patent, jointly owned by Sophia Space and Caltech, was filed in October 2024 and officially issued on July 14, 2026. It introduces a scalable architecture for constructing large, modular data centers in orbit that are specifically designed to harness solar energy while using the cold vacuum of deep space for passive thermal management.
Unlike terrestrial facilities, space-based data centers face a unique engineering challenge: cooling. Traditional cooling systems cannot function in orbit, requiring an entirely different approach to thermal control.
At the heart of the patented technology is Sophia Space's innovative "TILE" architecture, a modular computing and storage platform capable of being assembled into expansive orbital data center arrays. Powered continuously by sunlight, each module is engineered to dissipate waste heat by radiating it directly into deep space, eliminating the need for conventional cooling infrastructure.
The invention originated from an internal research and development program at NASA's Jet Propulsion Laboratory (JPL), managed by Caltech, which focuses on advancing high-risk, high-impact technologies beyond JPL's active mission portfolio.
The patent credits seven inventors representing expertise from JPL, Caltech, and Sophia Space, including Dr. John R. Brophy, Dr. Leon Alkalai, Prof. Sergio Pellegrino, Dr. Jonathan Sauder, Timothy P. McElrath, Dr. Douglas J. Sheldon, and Don J. Hunter.
Dr. Leon Alkalai, Founder and CTO of Sophia Space and a longtime JPL Fellow, established the company in 2023 to commercialize the technology through Mandala Space Ventures.
"You can't simply take a terrestrial data center and move it into space," said Dr. Alkalai. "Building data centers in space requires a completely different way of thinking about energy and thermal management. Our TILE architecture creates modular, scalable computing units that operate continuously using solar power while passively radiating heat into deep space."
From Space Solar Power to Orbital Computing
The concept builds upon earlier work conducted through Caltech's Space Solar Power Project, launched in 2013 with support from the Donald and Brigitte Bren Foundation. The project successfully demonstrated wireless power transmission from space to Earth in 2023.
That achievement inspired a new direction.
Rather than transmitting energy to Earth, researchers began exploring whether computing itself could move into orbit, allowing processed information, not raw data, to be transmitted back to Earth.
"The key technical challenge became cooling," Dr. Alkalai explained. "Once we solved that problem, the opportunity for space-based computing became much more compelling."
Public Research Driving Commercial Innovation
For JPL researcher Dr. John Brophy, the patent demonstrates how federally funded research can successfully transition into commercial technology.
"The space-based data center architecture described in this patent was developed as part of JPL's mission to address challenges of national significance," Brophy said. "This collaboration between JPL, Caltech, and private industry demonstrates how breakthrough technologies can rapidly move toward commercialization."
New Research Partnership to Advance Orbital Infrastructure
Alongside the patent announcement, Sophia Space revealed plans to deepen its research collaboration with Caltech through a new sponsored research agreement.
Working with Professor Sergio Pellegrino, the company will focus on developing lightweight deployable structures and advanced thermal management systems that could enable future generations of large-scale orbital computing platforms.
The research aims to overcome one of the biggest engineering challenges facing space-based infrastructure: creating enormous yet lightweight structures capable of supporting computing systems while efficiently managing heat in orbit.
A Growing Market for Computing in Space
Demand for orbital computing continues to accelerate as satellite constellations expand and artificial intelligence increasingly moves closer to the edge.
Future applications include:
AI inference directly in orbit
Real-time processing for Earth observation satellites
National security and defense missions
Communications and autonomous satellite operations
Commercial low Earth orbit infrastructure
Instead of transmitting vast amounts of raw satellite data to Earth for processing, future spacecraft could analyze information in orbit, dramatically reducing bandwidth requirements while improving speed, resilience, and operational responsiveness.
With its newly patented architecture and expanded partnership with Caltech, Sophia Space is positioning itself to become one of the companies helping build the digital infrastructure that may support the next era of the orbital economy.
