Every data center on Earth fights the same losing battle: cram in more compute, and you generate more heat that has to go somewhere. On the ground, "somewhere" means chillers, cooling towers, and increasingly, entire rivers diverted to keep server farms from cooking themselves. In orbit, there is no river. There is barely any air. And yet a growing chorus of AI infrastructure builders has started asking whether space — cold, sunlit, and free of zoning boards — might actually be the better place to put the next generation of data centers.

On July 14, 2026, Pasadena startup Sophia Space Inc. and Caltech were jointly issued U.S. Patent No. 12,679,564, covering a modular, solar-powered, passively cooled computing panel the companies call TILE. The filing, submitted in October 2024, describes a roughly 1-meter-by-1-meter, 1-centimeter-thick tile designed to generate its own power and dump its own waste heat directly into space — no pumps, no coolant loops, no moving parts to fail in the vacuum of orbit.

What the patent actually covers

TILE stands for Thermal Integrated LEO Edge, and the name is doing a lot of work. The core idea is modularity: rather than building one large, monolithic orbital computer, Sophia Space's design stacks or tiles together many identical thin panels, each one handling its own power collection and its own heat rejection. Because each tile radiates waste heat passively — relying on the panel's geometry and materials rather than active refrigeration — the system sidesteps one of the hardest engineering problems in space hardware: keeping electronics from overheating when there's no atmosphere to carry heat away by convection.

The patent lists seven inventors, spanning both institutions involved in its creation: John Brophy of NASA's Jet Propulsion Laboratory and Sergio Pellegrino of Caltech are named among them, reflecting the JPL-Caltech-industry pipeline that produced the technology in the first place.

From solar power research to server racks

The lineage matters here. TILE's modular-tile philosophy didn't emerge from a data center engineering team — it grew out of Caltech's Space Solar Power Project, a long-running effort originally funded by the Donald and Brigitte Bren Foundation starting in 2013. That project set out to solve a different but related problem: how to collect solar energy in orbit, convert it to radio frequency power, and beam it somewhere useful, all using the lightest possible hardware. Along the way, the team built what it describes as the lightest known integrated prototype to combine solar collection, RF conversion, and steerable wireless power transmission into a single modular element.

Swap "beam power to Earth" for "power an onboard processor" and "beam data instead of power," and you get the conceptual jump to TILE. It's the same bet — that thin, tiled, modular panels are the most mass-efficient way to do energy-intensive work in orbit — applied to a new target: computing itself.

Who's behind it

Sophia Space was founded in 2023 by Leon Alkalai, a retired JPL fellow, and operates as a portfolio company of Mandala Space Ventures. The company has raised $22 million to date. In the joint announcement of the patent, Alkalai framed the challenge in blunt terms: launching a data center into space means solving the "energy in and heat out" problem simultaneously, since there's no grid to draw from and no atmosphere to dump heat into. Brophy, for his part, pointed to the patent as an example of the kind of JPL-Caltech-industry collaboration that turns federally funded lab research into commercial hardware.

That collaboration isn't ending with the patent grant. Sophia Space and Caltech have signed a new sponsored-research agreement, extending the relationship beyond the technology already covered by the filing.

What happens next

Patents describe intentions; hardware in orbit proves them. Sophia Space says it plans an on-orbit demonstration of TILE in 2027, flying the hardware aboard an Apex Nova satellite bus — a commercial spacecraft platform built by Apex, one of a handful of companies now selling standardized "satellite chassis" the way cloud providers sell standardized server racks. Bolting a TILE demonstrator onto an existing bus, rather than building a custom spacecraft from scratch, is itself a signal of where this industry thinks it's headed: fast, modular, off-the-shelf infrastructure rather than bespoke missions.

Why It Matters

Space-based data centers have circulated as a thought experiment for years, usually dismissed on cost grounds — launching mass to orbit is expensive, and cooling electronics without air is genuinely hard. What's changed is the demand side: AI training and inference workloads have made terrestrial data centers voracious consumers of electricity and water, to the point that utilities and local governments are pushing back on new builds. That's turned "put it in orbit, where the sun never sets on solar panels and the cold of space is free" from a novelty pitch into something venture capital and national labs are willing to fund.

A patent alone doesn't prove TILE will work at scale, or that space-based compute will ever undercut a hyperscale data center on cost per operation. But this filing marks a concrete step: a named, testable engineering approach — thin, modular, passively cooled panels — backed by real Caltech and JPL research lineage, with a funded company and a scheduled 2027 flight test rather than a slide deck. If the on-orbit demo works, it will be one of the first hard data points on whether "compute in space" is an infrastructure category or just an appealing idea that runs into thermodynamics.
