Cowboy Space FCC Application for Stampede Satellite Data Centers

FCC File No. SAT-LOA-20260323-00135 identifies Cowboy Space Corp.’s request for authority to launch and operate Stampede, a proposed non-geostationary orbit (NGSO) satellite system designed to provide data center services from space. The Cowboy Space FCC application places the company inside a new regulatory category: space systems whose primary business function is compute capacity rather than communications, Earth observation, navigation, or broadcast services. As of May 15, 2026, the filing should be treated as a proposal under review, not as an approved constellation, completed system, or operating orbital data center network.

Cowboy Space, formerly known as Aetherflux, is a San Carlos, California company building orbital power, compute, and launch infrastructure. A May 8, 2026 company announcement described Cowboy Space as developing vertically integrated orbital data centers and rockets after raising $275 million in Series B financing. The proposed Stampede system would move part of the data center stack into orbit, where solar power is available for longer daily periods than at most terrestrial locations.

The filing package includes a legal narrative, a Technical Annex, Schedule S technical data, and an ownership exhibit. Together, the documents present Stampede as a system of up to 20,000 satellites in dawn-dusk sun-synchronous orbits between 700 and 1000 km altitude. A sun-synchronous orbit is a near-polar orbit whose plane shifts with Earth’s motion around the Sun, allowing a satellite to pass over locations at roughly consistent local solar time. For Stampede, that orbit choice supports the company’s central power argument: place computing hardware near sustained sunlight and reduce dependence on ground-based grid interconnection.

The Schedule S form presents four representative satellites in four orbital planes, with listed apogees and perigees between 830 and 860 km and an estimated operational lifetime of five years. The Technical Annex and legal narrative, by contrast, describe the full system concept as scaling up to 20,000 satellites. That difference matters because FCC applications often combine structured form data with explanatory exhibits, and the exhibits carry much of the meaning for unconventional systems that do not fit neatly inside standard form fields.

Cowboy Space frames the application around artificial intelligence, data center power demand, and national capacity. Its narrative says AI infrastructure faces power, land, cooling, interconnection, and permitting constraints on Earth. The filing points to the growth of data centers and argues that terrestrial grid connection timelines could slow deployment of large AI compute facilities. External market discussion follows the same pattern: Goldman Sachs projected a large increase in data center power demand by 2030, and Lawrence Berkeley National Laboratory’s 2024 U.S. data center report gives policy and industry analysts a detailed reference point for U.S. data center electricity consumption.

The application is not an authorization. It is a request for the Federal Communications Commission (FCC) to permit launch and operation under Part 25 satellite rules. The FCC’s space station licensing process includes application review, public notice, International Telecommunication Union (ITU) filing steps where required, technical analysis, and grant or denial action. For Stampede, the legal and policy questions are broader than ordinary spectrum coordination because the proposal combines compute, solar power, optical links, and a very large physical constellation.

The main elements of the Cowboy Space filing can be summarized as follows.

The Business Case Built Around Power, Compute, and Launch

Cowboy Space’s business argument starts with the idea that AI compute has become an infrastructure business, not only a software business. Large AI facilities need steady electricity, cooling systems, specialized chips, fiber connections, secure sites, and construction schedules that can match demand. Terrestrial data centers compete for power with electrified transportation, manufacturing, residential load growth, and industrial expansion. Stampede proposes a different physical model: generate power in orbit, run compute in orbit, and move data through optical links rather than move electricity through the terrestrial grid.

The company’s May 2026 rebrand sharpened that message. Aetherflux began with space-based solar power, using satellites to gather sunlight and send energy toward receivers on Earth through infrared lasers. Cowboy Space keeps that power theme but adds in-orbit AI data centers and launch infrastructure. The May 8, 2026 company announcement says each upper stage in the proposed architecture becomes a 1-megawatt data center in orbit. That claim makes the rocket part of the product, not just transportation for the product.

The company announced a $275 million Series B round at a reported $2 billion valuation, led by Index Ventures, with participation from investors including Breakthrough Energy Ventures, IVP, Construct Capital, Blossom Capital, SAIC, and Interlagos. NVIDIA’s space computing page states that Cowboy Space Corporation is bringing together NVIDIA Vera Rubin Space-1 Module, IGX Thor, and Jetson Orin to orbit to power AI-driven geospatial intelligence and autonomous space operations. That financing and supplier alignment give Cowboy Space more credibility than a paper concept, but they do not remove engineering, launch, regulatory, and customer-adoption risks.

The application’s theory of advantage depends on multiple linked assumptions. Solar access in orbit must translate into reliable electrical power for GPU-class hardware. Heat rejection must work in vacuum, where convection is unavailable and radiators carry much of the thermal burden. Optical communications must provide enough capacity, availability, and ground connectivity for the workloads Cowboy Space expects to serve. Launch costs must fall enough, or Cowboy Space’s own launch vehicle must mature enough, to make orbital data centers competitive with terrestrial alternatives.

The vertically integrated launch plan is especially important. TechCrunch reported on May 11, 2026 that Cowboy Space expects each satellite to have a mass of 20,000 to 25,000 kg and to generate 1 MW of power for just under 800 onboard GPUs. Those numbers imply a hardware class much larger than many communications satellites in low Earth orbit. A 20,000-satellite system at that mass would represent a launch, manufacturing, and capital program on a scale far beyond normal startup deployment patterns. Even if Stampede grows gradually, the long-term architecture would require an industrial base for spacecraft production, propulsion, power, avionics, thermal systems, ground stations, and launch operations.

Stampede also belongs to a larger orbital data center conversation. The FCC accepted SpaceX’s orbital data center application for filing in February 2026, involving a proposed NGSO system of up to one million satellites. Google’s Project Suncatcher paper, described by the company as a study of future space-based AI infrastructure, has added another large technology company to the debate. Cowboy Space differs by proposing to build launch vehicles around the data center payload itself, rather than waiting for third-party launch capacity to become cheap and abundant.

The practical commercial question is not simply whether compute can run in orbit. Satellites already use onboard processors, and spacecraft autonomy continues to improve. The harder question is whether high-performance AI compute can run in orbit at a cost, latency, reliability, and service quality that customers will buy. Early use cases may favor workloads that are tolerant of latency, can operate near space-generated data, or have defense and security demand that values resilience more than lowest-cost terrestrial performance.

How Stampede Would Use Orbits, Spectrum, and Optical Links

Stampede’s Technical Annex describes an NGSO system placed in dawn-dusk sun-synchronous orbital shells between 700 and 1000 km altitude. Those altitudes sit above many low Earth orbit broadband constellations and below medium Earth orbit. Cowboy Space says the selected shells are meant to maximize solar power availability and reduce overlap with large proposed SSO constellations. That is a strategic choice, because orbital altitude affects power access, visibility to ground stations, collision environment, deorbit timing, astronomical brightness, and coordination with other operators.

The use of dawn-dusk SSO supports solar exposure, but it also raises visibility questions. Satellites in sunlit orbits can reflect light during twilight, exactly when many astronomical observations occur. The Technical Annex says Cowboy Space will design and operate satellites to reduce reflectivity and will work with the astronomy community. It does not provide final spacecraft brightness values, final optical mitigation hardware, or a complete astronomy impact analysis. That gap is understandable for a system still in design, but it may draw attention during regulatory review because large constellations have already raised concerns among professional and amateur astronomers.

The communications design is unusual because Cowboy Space presents radiofrequency spectrum as a secondary tool. The Technical Annex says Stampede will principally rely on optical laser links among satellites, between satellites and the ground, and potentially with other NGSO systems under separate authority. Free-space optical communication can carry high data rates and use narrow beams, making it attractive for large data flows. It also requires precise pointing, atmospheric planning for ground links, and weather-diverse ground station networks if the system depends on optical downlinks to Earth.

For radiofrequency operations, Cowboy Space asks to use 18.8-19.3 GHz for space-to-Earth transmissions and 28.6-29.1 GHz for Earth-to-space transmissions. These sit within the Ka-band, a frequency range widely used for satellite communications. The company says the radio links would support telemetry, tracking, and command (TT&C), launch and early orbit phase (LEOP) operations, end-of-life maneuvers, orbit raising or deorbit activity, and emergencies where optical links are unavailable. The request is narrow compared with broadband satellite networks because Cowboy Space is not asking to use Ka-band as the main path for customer data.

The Technical Annex says TT&C bandwidths would range from 1 to 10 MHz and use directional antennas. It also says Cowboy Space would operate on a non-protected, non-harmful interference basis with respect to co-primary non-federal NGSO fixed-satellite service users and federal operations covered by footnote US334 of the U.S. Table of Frequency Allocations. The company says it will coordinate with the National Telecommunications and Information Administration and federal users before Ka-band operations where required.

The Schedule S data gives more detail on representative beams. Receive beams in 28.6-29.1 GHz include left-hand and right-hand circular polarization options, antenna pointing error of 0.1 degrees, and rotational error of 3 degrees. Transmit beams in 18.8-19.3 GHz show multiple gain and effective isotropic radiated power combinations, including TGA1, TGA2, and TGA3 beam families. The Technical Annex includes power flux density (PFD) analysis for 700 km and 1000 km cases and states that the proposed downlinks meet applicable PFD limits.

Cowboy Space also asks for authority during transition phases before and after reaching authorized shells. That request matters because satellites do not appear instantly in final orbit. Launch, checkout, phasing, orbit raising, and disposal periods can create different interference and space safety conditions than steady-state operations. A system with thousands of satellites would magnify the importance of transition operations, especially if deployment happens over years.

Regulatory Waivers at the Center of the Application

The Cowboy Space FCC application asks for waivers of multiple rules, including sections 25.155(b), 25.157(c), 25.164(b), 25.165, 2.106(a), 25.202(g)(1), and 25.114(a)(1). Waivers are common in satellite applications, but the scope of this request reflects the unusual nature of Stampede. Cowboy Space argues that standard procedures designed for spectrum-intensive NGSO communications systems do not fit a compute-focused system that mostly uses optical links.

Sections 25.155 and 25.157 address processing of satellite applications and NGSO-like satellite operations. Processing rounds are meant to handle mutually exclusive applications and protect fair access to shared spectrum. Cowboy Space argues that Stampede’s limited spectrum use does not create the same risk of precluding other operators from using the same bands. In that framing, the system should not be delayed or constrained by a process built for competing communications constellations.

Sections 25.164 and 25.165 concern deployment milestones and surety bonds. NGSO licensees generally face milestones requiring 50% deployment within six years and full deployment within nine years. Cowboy Space argues that those rules address spectrum warehousing, meaning the hoarding of scarce spectrum or orbital resources without service deployment. Because Stampede would use radiofrequency spectrum sparingly, the company says the bond and milestone framework does not match the main public-interest concern.

The application also asks for waivers tied to spectrum use for TT&C. Section 25.202(g)(1) generally concerns the placement of TT&C signals at band edges unless another frequency band is assigned for those functions. Cowboy Space argues that Stampede needs spectrum agility inside the requested Ka-band segments to coordinate with other operators and use narrow channels during selected mission phases. The company also requests a waiver related to the U.S. Table of Frequency Allocations under section 2.106.

Section 25.114 sets application content requirements for space station authorizations. Cowboy Space argues that Schedule S and the FCC’s software cannot fully capture all technical details for Stampede, making attached exhibits necessary. This is a practical issue for systems that combine power infrastructure, compute hardware, optical links, and limited conventional satellite communications.

The waiver requests can be summarized in a regulatory table.

The FCC does not have to accept Cowboy Space’s framing. Regulators can agree that Stampede is light on spectrum use and still conclude that a 20,000-satellite system creates public-interest issues beyond spectrum scarcity. Orbital debris, collision avoidance, astronomy, launch cadence, reentry risk, and international coordination all sit within or near the broader public-interest review. The strength of the waiver case may depend on whether the FCC treats Stampede mainly as a spectrum-light compute network or as a large physical occupation of heavily used orbital regions.

Orbital Debris, Astronomy, and Space Traffic Questions

A 20,000-satellite constellation would draw close attention even if it used almost no radiofrequency spectrum. Every satellite added to low Earth orbit becomes part of a shared physical environment. Operators must account for collision risk, maneuverability, end-of-life disposal, passivation of stored energy, reentry casualty risk, and operational coordination. The Cowboy Space Technical Annex says the company will comply with FCC orbital debris rules, but it also states that satellites are still being designed and that Cowboy Space will seek a modification once final satellite design is complete.

That approach mirrors a common regulatory tension. Early authorization can help a company raise capital, reserve program momentum, and coordinate future operations. Incomplete design information can make it harder for regulators and outside stakeholders to judge risk. For Stampede, this tension matters because the proposed constellation size is large, the satellites could be physically massive, and the target altitude range includes orbital regions where natural decay can take a long time without active disposal.

The Technical Annex says Cowboy Space will not intentionally release debris during normal operations and will not use separate deployment devices. It says each satellite will be designed so the probability of becoming debris through small-debris or micrometeoroid collision causing loss of control and preventing disposal is 0.01 or less. It also says the probability of collision with large objects during the total orbital lifetime, including deorbit phases, will be less than 0.001 unless effective maneuvering permits collision risk to be treated as zero during active avoidance periods. These are framed around FCC rule thresholds and the use of the NASA Debris Assessment Software or a higher-fidelity tool.

The final design will be important. A satellite with large solar arrays, radiators, optical terminals, onboard compute hardware, batteries, and propulsion systems may have a complex breakup and reentry profile. Thermal hardware may include materials that behave differently during reentry than ordinary aluminum satellite structures. Cowboy Space says all onboard batteries and propellant tanks will include failsafe mechanisms, stored energy will be removed at end of life, and no liquids that persist in droplet form will be present. Those commitments provide a framework, but detailed verification would require final hardware parameters.

Astronomy creates another review path. The Technical Annex says the company will reduce reflectivity and coordinate with the astronomy community. Professional concerns about large constellations usually involve reflected sunlight, streaks in optical images, radiofrequency interference, and unintended electromagnetic emissions. Cowboy Space’s limited spectrum strategy may reduce some radio concerns, but it does not answer all optical astronomy issues. Large satellites operating in dawn-dusk orbits could be visible during twilight, a time of special relevance for some surveys.

Space traffic coordination may be just as demanding as spectrum coordination. A 20,000-satellite system would require high-confidence tracking, maneuver planning, conjunction assessment, and communication with other operators. The application says Stampede will perform collision avoidance maneuvers throughout satellite life. Regulators may examine how autonomous maneuver decisions, operator coordination, and shared space situational awareness will work at scale. The FCC’s space station review process has become more important as NGSO constellations have grown larger.

International concerns may appear as well. Stampede would be a U.S.-licensed system, but satellites at 700 to 1000 km pass over many countries and share orbital regions with operators from multiple jurisdictions. International coordination can involve the International Telecommunication Union, national regulators, space safety organizations, astronomy groups, and foreign satellite operators. Even where the FCC controls a U.S. license, the external effects of a large constellation do not stop at national borders.

Defense and Security Uses Behind the Power Grid in Space

Cowboy Space’s application includes a defense and security dimension that goes beyond AI data center economics. The legal narrative states that the company secured funding through the Operational Energy Capability Improvement Fund for a proof of concept involving wireless space-to-Earth power transmission. The Department of Defense’s Operational Energy Innovation office describes the Operational Energy Capability Improvement Fund and the Operational Energy Prototyping Fund as programs that develop and prototype technologies to support operational energy needs.

Operational energy is a longstanding defense logistics problem. Military forces need power for communications, sensors, computing, electronic systems, and base operations. Remote installations can depend on fuel deliveries that create logistical exposure. A space-based power or compute system could interest defense users if it provides resilient service to locations where terrestrial infrastructure is weak, damaged, monitored, or politically difficult to access. That does not mean Stampede is primarily a military system, but the defense use case can help explain early funding and policy attention.

For AI compute, defense demand may center on data processing, autonomy, and resilience. Space-based systems can process sensor data near its source, reduce dependence on some ground facilities, and support missions where communications links are constrained. An orbital compute node could also serve space missions directly, including Earth observation satellites, communications relays, or spacecraft that need processing assistance. Those applications differ from terrestrial hyperscale AI training, which demands vast energy, enormous chip clusters, and high-speed interconnects inside controlled facilities.

The application’s emphasis on U.S. AI leadership also aligns with federal policy attention to data center infrastructure. Cowboy Space cites executive-branch actions on AI policy and data center permitting, including Executive Order 14318 on federal data center permitting and Executive Order 14365 on a national AI policy framework. That framing places Stampede inside a larger national competitiveness argument: if compute power becomes a strategic resource, new power and compute architectures may attract regulatory, defense, and industrial policy attention.

The national security case creates its own review questions. A large orbital data center system could become a strategic asset, and strategic assets require careful attention to protection, continuity, attribution, and escalation risk. Satellites face natural hazards, cyber risk, interference attempts, debris events, and ground segment vulnerabilities. Optical links can be narrow and hard to intercept compared with broad radio beams, but they depend on pointing, timing, terminal security, and ground infrastructure. A compute system serving sensitive workloads would need security controls that extend from chip hardware to command links, software supply chains, ground stations, and customer interfaces.

Defense and security customers may also demand performance features that commercial customers do not require. They may value availability in specific theaters, service under degraded conditions, hardened communications, and documented control over supply chains. Cowboy Space’s plan to build vertically integrated infrastructure could support that message if the company can execute. It could also increase schedule risk because rockets, satellites, compute payloads, optical links, ground terminals, and mission operations all need to mature together.

The FCC review does not decide defense procurement outcomes. It can authorize or deny communications-related space station operations and impose conditions related to its rules. Other government agencies would influence export control, launch licensing, cybersecurity, defense contracting, spectrum coordination, and national security review where applicable. Stampede’s defense relevance may help explain interest in the system, but it does not replace the need for technical proof, safe operations, and lawful licensing.

Execution Risks for a Vertically Integrated Space Data Center Plan

Cowboy Space’s plan is ambitious because it combines multiple difficult businesses that usually mature separately. Launch vehicle development is capital intensive and schedule-sensitive. Satellite production requires reliable supply chains and testing. In-orbit data centers need power electronics, thermal systems, computing hardware, radiation management, and software orchestration. Optical networks require ground terminals, pointing systems, cloud integration, and service-level design. Stampede asks investors, regulators, customers, and partners to believe that these layers can be integrated into one commercially useful system.

Thermal management is one of the most important technical issues. Terrestrial data centers use air handling, liquid cooling, chilled water, evaporative systems, and other methods to remove heat. In orbit, heat must move through conduction inside hardware and radiation into space. GPUs produce substantial heat under load, and a dense orbital compute system needs radiators sized for sustained operation. Large radiators can increase mass, drag profile, brightness, and mechanical complexity.

Radiation and reliability create a second issue. Space hardware faces charged particles, single-event effects, thermal cycling, vacuum, launch vibration, and long-duration exposure. Commodity data center equipment is not automatically suitable for orbit. Space-qualified compute hardware usually costs more and may lag the newest terrestrial chips. NVIDIA’s March 16, 2026 space computing announcement says the NVIDIA Space-1 Vera Rubin Module was introduced for orbital data centers, geospatial intelligence, and autonomous space operations, with availability planned for a later date. Turning modules into a commercial orbital data center service requires system-level integration, maintenance strategy, and fault tolerance.

Maintenance strategy may prove especially difficult. Terrestrial data centers replace failed servers, swap components, upgrade chips, and adjust cooling systems. Orbital systems have fewer repair options. A satellite data center must either tolerate failure, route work around degraded units, support robotic servicing, or accept shorter replacement cycles. Cowboy Space lists a five-year estimated operational lifetime in Schedule S. A five-year cycle may fit some satellite models, but data center economics often depend on hardware refresh schedules, depreciation, utilization, and customer commitments.

Launch economics also dominate the plan. Cowboy Space’s public statements suggest that third-party launch capacity may be too scarce or expensive for the scale it wants. Building a dedicated launch vehicle could reduce dependence on outside providers if successful. It could also move the company into direct competition with organizations that have spent years and large sums to reach reliable launch operations. The proposed architecture, where the upper stage becomes the data center, may reduce redundant structure. It also ties rocket design tightly to data center design, which can make changes harder once development choices are locked.

Regulation adds another schedule path. The FCC application is one part of the approval stack. A launch vehicle would involve launch and reentry licensing from the Federal Aviation Administration’s Office of Commercial Space Transportation. Export controls, ground station licenses, environmental review, spectrum coordination, cybersecurity requirements, and international operations could add further steps. The FCC’s licensing process provides a path for satellite authorization, but unconventional systems can raise additional review questions.

Customer demand is the commercial test. Some workloads may benefit from orbital compute, especially if data originates in space, service resilience matters, or power constraints on Earth create bottlenecks. Other workloads may stay on Earth because terrestrial data centers offer lower cost, easier maintenance, lower latency, and deep integration with cloud networks. Stampede’s success would depend on matching orbital strengths to customer needs rather than assuming all AI compute is equally suited to space.

What the Application Means for the Space Economy

Stampede would broaden the space economy if it advances beyond application and demonstration. Traditional satellite business models sell connectivity, imagery, positioning, weather data, hosted payload capacity, or government mission services. Cowboy Space proposes to sell compute from orbit, with the satellite acting as power plant, data center, and network node. That shifts the business case from moving information through space to moving part of the information economy into space.

Manufacturing would become an important part of the value chain. A 20,000-satellite concept would require repeatable production of structures, solar arrays, radiators, processors, power electronics, optical terminals, propulsion systems, and avionics. Suppliers in semiconductors, space-qualified electronics, advanced materials, thermal hardware, robotics, and ground equipment could benefit if the architecture matures. The company’s vertical integration plan may internalize some of that demand, but no large aerospace system avoids supplier dependence entirely.

Launch demand would be substantial. If Cowboy Space builds its own vehicle, it may create a new dedicated launch category for very large orbital infrastructure. If the company later uses external providers for some missions, it could become a heavy customer for medium or super-heavy launch. Either path would affect launch site planning, range availability, production capacity, insurance, environmental review, and workforce needs.

Insurance and finance would also matter. In-orbit data centers create exposure to launch failure, early satellite failure, debris collision, service interruption, cybersecurity events, and hardware obsolescence. Insurers and lenders would need to price risks that combine satellite operations with data center service commitments. Venture capital may support demonstrations and early deployment, but full-scale buildout would likely need a much deeper capital stack if the system grows toward thousands of satellites.

Ground infrastructure remains part of the story even if Cowboy Space bypasses grid interconnection for compute power. Optical ground stations, TT&C sites, customer network connections, security operations centers, mission control facilities, manufacturing plants, launch pads, and test sites all require terrestrial assets. Space data centers do not eliminate Earth infrastructure. They change which infrastructure is needed and where it sits.

Policy may become the largest shared issue. If orbital data centers become an active application category, regulators may need clearer rules for systems that are spectrum-light but physically large. Current satellite rules focus heavily on spectrum, orbital debris, licensing milestones, and service definitions. Orbital compute systems raise additional questions about brightness, heat rejection, cyber operations, on-orbit servicing, data jurisdiction, customer protection, and disposal of large hardware.

Cowboy Space’s filing may influence competitors even if Stampede changes shape. A serious application can reveal how a company wants regulators to view orbital data centers. It can trigger comments from satellite operators, astronomers, spectrum users, defense stakeholders, environmental groups, and potential customers. It can also give other firms a regulatory template to accept, modify, or challenge.

Summary

The Cowboy Space FCC application turns orbital data centers from a conference-stage concept into a licensing question. Stampede is proposed as a solar-powered NGSO system of up to 20,000 satellites, using optical links for most communications and narrow Ka-band TT&C for selected mission phases. The application’s core claim is that compute infrastructure can move closer to orbital sunlight and away from terrestrial grid bottlenecks.

The strongest part of the filing is its clear connection between AI power demand, space solar exposure, optical communications, and vertical launch integration. The weakest part, at this stage, is the amount of final design information still missing for satellites that could be large, bright, numerous, and operationally complex. Cowboy Space has financing, a public strategy, and a specific FCC request, but it still needs to demonstrate launch capability, orbital compute economics, thermal design, space safety performance, customer demand, and regulatory acceptance.

Stampede’s regulatory path may matter as much as its engineering path. If the FCC treats the system mainly as a limited-spectrum satellite network, Cowboy Space’s waiver arguments may have force. If regulators and stakeholders treat it as a large physical occupation of shared orbital space, the debate may center more on debris, astronomy, collision avoidance, reentry, and international effects. That distinction could shape how future orbital data center applications are reviewed.

Appendix: Top Questions Answered in This Article

What Is Cowboy Space Asking the FCC to Approve?

Cowboy Space is asking the Federal Communications Commission for authority to launch and operate Stampede, a proposed NGSO satellite system designed to provide data center services from space. The attached filing materials describe a system that could scale to as many as 20,000 satellites in dawn-dusk sun-synchronous orbits between 700 and 1000 km altitude.

Is Stampede Already Approved?

Stampede should be treated as a proposed system as of May 15, 2026. The application asks for launch and operating authority, but an application is not the same as a grant. The FCC can approve, deny, defer, condition, or require changes to the proposal after reviewing technical, legal, and public-interest issues.

Why Does Cowboy Space Want Data Centers in Orbit?

Cowboy Space argues that AI data centers face power, land, cooling, and grid interconnection limits on Earth. The proposed orbital model would place compute hardware near sustained sunlight and use optical links to move data. The business logic depends on making orbital power, compute, launch, and communications work together at competitive cost.

How Many Satellites Would Stampede Include?

The Technical Annex describes Stampede as a system of up to 20,000 satellites. Schedule S lists four representative satellites in four orbital planes, but the broader narrative and annex describe the larger system concept. Final deployment would depend on FCC authorization, spacecraft design, launch capacity, capital, and customer demand.

What Frequencies Would Stampede Use?

Cowboy Space requests use of 18.8-19.3 GHz for space-to-Earth transmissions and 28.6-29.1 GHz for Earth-to-space transmissions. The application says these Ka-band links would mainly support TT&C during launch, early operations, end-of-life activity, and emergencies. Routine data movement would rely mainly on optical laser links.

Why Are Optical Links Central to the Filing?

Optical links allow high-capacity communications through narrow beams and reduce reliance on scarce radiofrequency spectrum. Cowboy Space uses that point to support its waiver arguments, especially around NGSO processing rounds and spectrum warehousing. Optical links still require precise pointing, atmospheric planning, ground station diversity, and strong operational controls.

What Waivers Does Cowboy Space Request?

Cowboy Space requests waivers related to NGSO processing rounds, deployment milestones, surety bonds, TT&C spectrum placement, and Schedule S limitations. The company argues that Stampede’s limited radiofrequency use makes some standard rules poorly matched to the system. The FCC can accept that logic, reject it, or grant authority with conditions.

What Are the Main Space Safety Issues?

The main space safety issues include collision avoidance, debris mitigation, end-of-life disposal, stored-energy passivation, and reentry risk. Cowboy Space says it will comply with FCC debris rules and submit updated details after final satellite design. Stakeholders may focus on whether a 20,000-satellite system can operate safely at 700 to 1000 km altitude.

Why Does Astronomy Matter for Stampede?

Astronomy matters because many satellites in sunlit orbital regimes can reflect sunlight and affect observations. Cowboy Space says it will design satellites to reduce reflectivity and work with astronomy interests. The final impact depends on spacecraft size, surface materials, orbital geometry, brightness mitigation, and the number of satellites deployed.

What Makes Cowboy Space Different From Other Orbital Data Center Concepts?

Cowboy Space is proposing vertical integration that includes satellites, power, optical transmission, compute payloads, and a purpose-built launch vehicle. The company’s public plan treats the rocket upper stage as part of the orbital data center. That model may reduce some redundant mass, but it also increases development complexity and schedule risk.

Appendix: Glossary of Key Terms

Cowboy Space Corp.

Cowboy Space Corp. is the company behind the Stampede application. It was formerly known as Aetherflux and is headquartered in San Carlos, California. Its public strategy combines space-based power, in-orbit compute, optical communications, and dedicated launch infrastructure for AI-related services.

Stampede

Stampede is the proposed Cowboy Space satellite system described in the FCC application. The filing presents it as a scalable NGSO system of in-orbit data centers powered by solar energy. It would use optical links for most communications and limited Ka-band spectrum for selected control functions.

Federal Communications Commission

The Federal Communications Commission is the U.S. agency that licenses many commercial satellite communications systems. For Stampede, the FCC review centers on space station authorization, spectrum use, orbital debris disclosures, waiver requests, and public-interest conditions tied to launch and operation.

Non-Geostationary Orbit

Non-geostationary orbit refers to satellites that do not remain fixed over one point on Earth. NGSO systems include low Earth orbit, medium Earth orbit, and other moving orbital patterns. Stampede is proposed as an NGSO system because its satellites would circle Earth rather than stay over one longitude.

Sun-Synchronous Orbit

A sun-synchronous orbit is a near-polar orbit designed so the satellite crosses locations at roughly consistent local solar time. Cowboy Space proposes dawn-dusk sun-synchronous orbits because they can provide long solar exposure periods, which supports the company’s power-centered data center concept.

Telemetry, Tracking, and Command

Telemetry, tracking, and command refers to the control and monitoring link between a spacecraft and operators. TT&C allows operators to receive spacecraft health data, determine spacecraft position, send commands, and manage mission phases. Stampede would use narrow Ka-band channels for TT&C in selected situations.

Ka-Band

Ka-band is a microwave frequency range used in many satellite systems. Cowboy Space requests access to portions of Ka-band for limited TT&C operations rather than ordinary broadband customer service. Ka-band use requires interference management, antenna design, and coordination with other users.

Optical Laser Link

An optical laser link uses light to transmit information through free space. In satellite systems, optical links can connect satellites to each other or to ground stations. They can support high data rates but require precise pointing and are affected by cloud cover and atmospheric conditions for ground links.

Orbital Debris Mitigation

Orbital debris mitigation covers practices that reduce the creation of long-lived space debris. It includes avoiding intentional debris release, limiting explosion risk, designing for disposal, managing collision risk, and assessing reentry hazards. Large constellations face close review because each satellite adds to the shared orbital environment.

Processing Round

A processing round is an FCC procedure for considering mutually exclusive NGSO satellite applications that seek access to the same spectrum. Cowboy Space argues that Stampede’s limited radiofrequency use should reduce processing-round concerns. The FCC may still examine broader public-interest effects beyond spectrum access.
