Some workloads are easier
to run above the atmosphere.
The thesis is not that computers belong in space. The thesis is that some of the hardest constraints on Earth-based computing are energy, heat, and land — and that orbit changes the shape of those constraints for specific future workloads.
Energy
Orbital photovoltaic systems operate in sunlight for most of the duty cycle, without the diurnal swings, weather variability, or grid-interconnect delays that constrain terrestrial clean power. Power becomes a function of array area and orbital geometry — not land use or transmission capacity.
Cooling
There is no air in orbit. Heat leaves through radiation — engineered via large emissive surfaces designed to dump thermal load at the right wavelengths. This removes the need for evaporative water loops and local heat-island effects. It also demands serious thermal design; nothing about this is automatic.
Land & permitting
Orbital infrastructure does not compete with housing, agriculture, or ecosystems for space. It does not trigger the years-long permitting and interconnect processes that gate new terrestrial builds. For certain workloads, that alone changes the economics.
Water & grid strain
A share of hyperscale data-centre footprints consume significant volumes of water for cooling. Shifting a portion of workload off-planet can reduce pressure on local water systems and grid capacity, especially in regions where both are already constrained.
Workload fit
Orbital compute is not for real-time user traffic. It is for workloads that tolerate orbital propagation delays: large-model training, batch inference, scientific simulation, long-baseline data processing, archival pipelines, and compute tied to space-native data sources.
Niche-first
Inorbii is explicit about this: we are not replacing Earth data centres. We are building an additional class of infrastructure for the workloads where orbital deployment may become economically and technically meaningful over the next decade.
Radiative cooling is the
central engineering problem.
In orbit, the only outbound path for waste heat is electromagnetic radiation. That makes the radiator field as critical as the solar array. Its area, orientation, emissivity, and materials define how much compute the platform can sustain. Thermal design is not a constraint on the platform. It is the platform.
