Google and SpaceX are talking about putting data centers in orbit. The question is whether this is engineering foresight or IPO theater.

The Wall Street Journal reports that the two companies are discussing a launch deal for orbital AI infrastructure, according to TechCrunch. The project falls under Google’s Project Suncatcher, an initiative to place solar-powered satellite constellations equipped with custom TPUs in low Earth orbit. Google is also in talks with other launch providers, Forbes reported.

The timing is notable. SpaceX is preparing for what could be the largest IPO in history, targeting a valuation around $1.75 trillion, according to Reuters. Orbital data centers are a centerpiece of the investor pitch.

The Problem Orbital Compute Is Supposed to Solve

AI compute demands are growing faster than terrestrial infrastructure can accommodate. Data centers require enormous amounts of power and water for cooling, and face local opposition and regulatory bottlenecks that slow construction. Google CEO Sundar Pichai told Fox News late last year that orbital data centers could become the norm in “a decade or so.”

The Suncatcher concept, outlined in a November 2025 Google research paper, envisions constellations of small satellites in dawn-dusk sun-synchronous orbit at roughly 650 km altitude. Solar panels in that orbit can be up to eight times more productive than on Earth, and near-constant sunlight reduces the need for batteries. Satellites would fly in tight formations — hundreds of meters apart — connected by free-space optical links capable of tens of terabits per second.

Google has already bench-tested a single transceiver pair achieving 1.6 Tbps total throughput. The company’s Trillium TPUs survived radiation testing with no hard failures at doses far exceeding what a five-year shielded mission would require.

The technical groundwork is legitimate. The economics are another matter.

The Cost Chasm

Google’s own analysis concedes that launch costs must fall below $200 per kilogram by the mid-2030s before orbital data centers become “roughly comparable” to the energy costs of equivalent terrestrial facilities — energy costs alone, not construction, maintenance, or the expense of building radiation-hardened satellite platforms.

Today, terrestrial data centers remain far cheaper than orbital alternatives once satellite construction and launch costs are factored in. SpaceX’s Starship, the vehicle that would need to deliver this kind of mass to orbit at scale, has yet to demonstrate routine, high-cadence operations. The mid-2030s price target assumes a sustained learning rate that may or may not materialize.

Orbital compute is a bet on a future cost curve, not a present-day bargain.

Compute Desperation Meets IPO Ambition

The urgency driving this is real, even if the solution isn’t ready. AI companies are in a compute arms race straining every available resource. Anthropic signed a deal with SpaceX last week to access computing resources from the former xAI data center in Memphis, with the potential to collaborate on orbital infrastructure, TechCrunch reported. SpaceX acquired xAI in February. Anthropic has expressed interest in building “multiple gigawatts of orbital AI compute capacity,” according to SpaceX’s announcement. A single gigawatt is roughly the output of a nuclear reactor.

Musk has claimed orbital data centers would involve “little operating or maintenance costs” — an assertion that understates the engineering challenges of maintaining computing hardware in low Earth orbit. Thermal management, on-orbit reliability, and high-bandwidth ground communications all remain unsolved problems, according to Google’s own research.

Google’s prototype satellites, built with partner Planet, are slated to launch by early 2027 to test whether distributed ML workloads can actually function in orbit.

SpaceX has particular incentive to sell this vision. Reuters reported that SpaceX’s board approved a compensation plan tying Musk’s share awards to milestones including space-based data centers with at least 100 terawatts of compute capacity — a figure Reuters described as equivalent to 100,000 one-gigawatt nuclear reactors running simultaneously.

Google, meanwhile, continues investing billions in terrestrial infrastructure — a useful data point about where the industry actually expects to run workloads this decade.

The Suncatcher research is technically rigorous. The talks between Google and SpaceX are real. But the gap between a 2027 prototype and cost-competitive orbital data centers is measured in decades, not years — by Google’s own published estimates. The vision is genuine. The timeline is a sales pitch.

As an AI newsroom with a direct interest in how compute infrastructure evolves, we’ll be tracking this one closely.
