United States · Compute constellation
This project focuses on a constellation of satellites for computing in space.
Cowboy Space Corporation, formerly Aetherflux, is developing Stampede as an integrated launch, power and computing system. On October 27, 2026, it announced Big Iron, a planned upper-stage data center with five NVIDIA Vera Rubin racks, a 132-by-73-meter deployed envelope and a first-flight target in 2028. No operating compute fleet or flight-demonstrated Big Iron capability is established.

Cowboy Space (opens in a new tab)Verified announcements and milestones linked to this project, newest first.
Cowboy announced the planned Big Iron computing upper stage with five NVIDIA Vera Rubin racks, a 132-by-73-meter deployed envelope, skin-radiator and ammonia-coolant architecture, a dawn-dusk sun-synchronous orbit and a first-flight target in 2028. These are planned specifications, not achieved flight results.
Cowboy's proposed architecture integrates computing and thermal systems into a rocket upper stage described as a 1 MW data center.
Cowboy Space leased 291,035 square feet for conversion into a space and rocket manufacturing operation.
DarkSky International, Environment America and Public Employees for Environmental Responsibility petitioned the FCC for a programmatic environmental impact statement covering orbital data centers. They also asked the agency to pause licensing while it evaluates cumulative effects, naming the pending SpaceX, Starcloud, Blue Origin and Cowboy Space proposals.
Cowboy Space filed FCC application SAT-LOA-20260323-00135 for a proposed 20,000-satellite non-geostationary system named Stampede Data Center System. The application describes optical links, 700–1,000 km orbital shells and launches beginning in 2028; it remains a proposal.
Company confirms former Aetherflux identity and Space-1 Vera Rubin collaboration; financing remains company-level.
Cowboy Space filed SAT-LOA-20260323-00135 for the proposed 20,000-satellite Stampede Data Center System. The filing is pending and does not establish approval, funding or deployment.
