Space infrastructure company / Luxembourg
01 / mission
Make orbital compute usable as infrastructure
The goal is not to make space sound futuristic. The goal is to make orbital compute technically credible, commercially accessible, and operationally dependable.
Model 1
Mission engineering
Define the flight gates, spacecraft interfaces, orbital assumptions, and verification plan.
Model 2
Payload systems
Design compute, storage, power, thermal, RF, and fault behavior as one payload.
Model 3
Software infrastructure
Make orbital capacity usable through APIs, scheduling, receipts, and customer delivery.
Model 4
Commercial partnerships
Connect spacecraft, launch, hardware, ground networks, cloud platforms, and early customers.
02 / company model
A company built around systems integration
Orbital data centers require spacecraft, software, thermal, storage, operations, and commercial infrastructure to come together as one service.

Spacecraft + software + thermal + ops one team
STELLAR / COMPANY / OPERATING MODEL
STELLAR operating model
Four engineering disciplines, five partner classes, one orbital service. Each discipline owns a slice; partners compound external leverage; integration is the actual product.

Orbital service · compute + storage + verified delivery
One orbital service, four integrated disciplines
Mission baseline → integrated payload → usable capacity → customer pull. Integration is the deliverable.

Start with Node-1, scale toward mesh
STELLAR begins with Node-1, a hosted payload program designed to validate the interfaces, software, thermal constraints, and operating model required for orbital data-center services.
