Blue Origin and SpaceX are pursuing orbital computing, but neither has an operating space data-center service established by the available evidence. Blue Origin has announced TeraWave, a planned satellite communications network, while its separate Project Sunrise compute proposal is described in reporting on a regulatory filing. SpaceX has outlined its own orbital-data-center plans in a regulatory filing. The competition is real as a contest over future infrastructure; it is not yet a race between proven services.
Blue Origin’s plan pairs proposed compute with announced connectivity
Project Sunrise is the reported compute proposal
TechCrunch reported in 2026 that Blue Origin sought authorization for a Project Sunrise constellation of more than 50,000 satellites intended for orbital data centers. The reporting describes TeraWave as a communications backbone for the project. The available sources do not establish that Sunrise has been authorized, deployed, or assigned paying compute workloads.

TeraWave is a communications network, not an announced AI data center
Blue Origin announced TeraWave on January 21, 2026, as a planned network for enterprise, data-center, and government users. Its design calls for 5,280 low Earth orbit (LEO) satellites to connect customers and 128 medium Earth orbit (MEO) satellites to provide optical links, with capacity of up to 6 terabits per second (Tbps). Blue Origin says deployment is planned to begin in Q4 2027. Those are company-stated plans and capacity claims, not measured performance from an operating service; the announcement describes connectivity, not orbital AI computing.

How the proposals compare
| Dimension | Blue Origin | SpaceX |
|---|---|---|
| What is proposed | Project Sunrise is reported as an orbital compute constellation; TeraWave is the separate planned connectivity network. | SpaceX has described plans to develop and operate orbital data centers. |
| Disclosed scale and orbit | More than 50,000 satellites sought for Sunrise, according to TechCrunch’s 2026 reporting. TeraWave’s announced design is 5,408 satellites across LEO and MEO. | The cited filing describes a proposed configuration, but the sources summarized here do not establish a directly comparable total satellite count. |
| Schedule | Blue Origin says TeraWave deployment will begin in Q4 2027. No Sunrise deployment schedule is established in the cited reporting. | No deployment date for orbital data centers is established by the cited filing. |
| Connectivity and customers | TeraWave is aimed at enterprise, data-center, and government connectivity; Blue Origin describes it as a potential backbone for Sunrise. | SpaceX has presented orbital computing ambitions, but the cited material does not establish a paying customer or contracted workload. |
| Regulatory position | Sunrise is described in reporting on an authorization request; the cited sources do not establish approval. | SpaceX’s configuration and orbit-sharing claims appear in its own regulatory advocacy. The cited sources do not establish a final authorization outcome. |
| Evidence of operating compute service | No deployed Sunrise compute service or contracted workload is established. | No deployed orbital compute service or contracted workload is established. |
The evidence behind these entries is not equivalent: TeraWave’s numbers and schedule are from Blue Origin’s announcement, Sunrise’s scale comes from reporting on a filing, and SpaceX’s configuration arguments come from SpaceX’s own submission. SpaceX argues that its proposed orbital shells can accommodate other operators and describes coordination measures; those are company positions in a contested proceeding, not independent regulatory findings.

Why data centers in space are not simply solar-powered terrestrial data centers
Power requires more than sunlight
Suitable orbits can provide abundant sunlight, but a computing satellite also needs large solar arrays and storage for periods in eclipse. Those systems add mass and compete with computing hardware for launch capacity. A design’s ability to generate power continuously depends on its orbit and storage assumptions, not on sunlight alone.
Heat has to be radiated away
Computer chips produce heat, and vacuum does not carry it away through air as a terrestrial cooling system can. Heat must be rejected through radiators. Northeastern University professor Josep Jornet told the Associated Press that “An uncooled computer chip in space would overheat and melt much faster than one on Earth.” Radiator size, mass, and durability therefore form part of the data-center design rather than a secondary cooling detail.

Radiation and maintenance affect useful life
Radiation can damage electronics, while conventional repair access is absent for an uncrewed satellite. Operators would have to design for radiation tolerance, spacecraft lifetime, failure rates, and replacement cadence. Replacing failed or aging hardware means further launches and introduces costs that do not disappear just because the facility is in orbit.
Communications and utilization shape the business case
Compute is only useful if data can reach the spacecraft and results can return to users at acceptable speed and cost. Blue Origin’s TeraWave announcement is relevant as a planned connectivity layer, but it does not by itself demonstrate that an orbital compute service can meet terrestrial customers’ needs. Operators would also need enough sustained workload to keep expensive launched capacity in use; the cited sources do not establish contracted compute demand for either proposal.

What the available cost estimates say—and do not say
Novaspace’s 2026 white paper models a 1-gigawatt data center over five years at $46 billion in space, compared with $17 billion for its terrestrial case. These are scenario estimates under the white paper’s assumptions, not observed costs from an operating orbital data center. Novaspace says the space case remains substantially more expensive even with optimistic assumptions about launch and satellite manufacturing.
A separate technical-economic preprint by Slava G. Turyshev, dated April 29, 2026, models a representative 1-megawatt, high-sunlight scenario. It estimates beginning-of-life photovoltaic area of 5.64 × 10³ square meters and radiator area of 2.50 × 10³ square meters. These modeled areas illustrate the scale of power and heat-rejection hardware in that scenario; they are not measurements from a built system. Turyshev’s analysis points to space-native processing and communications-integrated edge computing as more credible early uses than general-purpose compute serving terrestrial users.

For investors and customers, the implication is that large announced constellations do not yet establish a viable data-center business. Launch costs, hardware lifetimes, repair limits, utilization, and connectivity all influence total cost, while the available estimates remain models rather than operating accounts. No cited source establishes a paying customer or contracted compute workload for either company’s proposed orbital data-center system.
Quick Recap
Milestones that would show whether the race is becoming a service market
- Regulatory decisions: official FCC outcomes for Project Sunrise and SpaceX’s proposal, rather than company filings or reported requests alone.
- Deployment evidence: whether Blue Origin begins the TeraWave deployment on its stated Q4 2027 schedule; that milestone concerns the announced connectivity network, not proof of Sunrise compute.
- In-orbit demonstrations: working systems that demonstrate compute performance, heat rejection, power through eclipse periods, and communications under operational conditions.
- Commercial demand: named customers or contracts specifying real compute workloads, instead of broad target-customer categories.
- Independent cost evidence: operating data on launch, replacement, uptime, and utilization that can be compared with terrestrial facilities.
