Dependency map
Prerequisites for power & compute outcomes.
Each outcome shows what already exists, what is being built, and the weakest missing link.
Orbital computing infrastructure
Computing in orbit may support Earth observation, communications, and data services, but scale is limited by power, heat, maintenance, and economics.
- Weakest link
- thermal rejection and economic advantage over terrestrial systems
- Closest equivalent today
- onboard processing, edge-compute demonstrations, and satellite data services
Utility-scale space solar power
Space solar power has demonstrations and serious analysis, but a utility-scale economic system remains unproven.
- Weakest link
- launch/assembly cost, safe transmission, maintenance, and terrestrial competition
- Closest equivalent today
- solar-powered spacecraft and power-beaming research
A Dyson swarm
A Dyson swarm is a civilization-scale imagination boundary, useful only as an extreme endpoint for power and industry dependencies.
- Weakest link
- everything from materials to autonomous industry to social purpose
- Closest equivalent today
- solar-powered spacecraft and early power-beaming research
Who is working on it
The organizations actually moving power & compute forward.
Agencies, commercial teams, researchers, and operators all contribute differently — and they're not all at the same stage.
NASA
Connected to power & compute through capability evidence, technology work, operations, or program demand.
Planned work
Active programs with real hardware behind them.
Near-term work is shown with its target type, current hardware state, and the sources that back it up.
Fission Surface Power
Continuous surface power could change the lunar night problem and later Mars base design.
- Target label
- Official government target: early 2030s lunar-class system goal
- Hardware state
- Design, fabrication, and test work is underway; no lunar reactor has been deployed.
What the teams are trying to prove
The specific tests and demonstrations that could change power & compute.
Each one is concrete because it clears a real dependency — it's not a milestone for its own sake.
laser communications demonstrations
in-orbit compute and storage tests
space-to-Earth power transmission research
large thermal-management studies
What remains unsolved
The hard problems still standing in power & compute's way.
These are the unsolved questions that will ultimately determine whether this pathway gets to routine — not whether it gets to demonstration.
Thermal management for large orbital systems
Radiators add mass, area, pointing constraints, vulnerability, and maintenance demands.
A large orbital platform demonstrates heat rejection at the scale required for power or compute service.
Sustainable economic demand
Many futures need demand outside government exploration budgets.
Multiple non-government customers buy repeat services that cover operations, maintenance, and growth.
Autonomous construction and maintenance
Robots must work with poor lighting, delay, dust, radiation, moving parts, and incomplete information.
A robotic system builds, inspects, repairs, or upgrades a mission-critical asset with limited crew intervention.
Governance and liability
Infrastructure needs standards and authority before routine operations become safe and insurable.
Clear interoperable rules support rescue, docking, traffic coordination, resource use, and accountability.
A day in this future
What power & compute would actually look like.
A concrete scenario paired with today's reality — so the future stays vivid without losing its honesty.
Scenario
A useful orbital data platform would need flown hardware, compute actually demonstrated in orbit, a paying customer, a clear scale advantage, radiation tolerance, high-bandwidth downlink, and heat rejection that does not overwhelm the spacecraft.
Reality check
Space can already deliver communications and Earth data. Utility power and large data centers remain frontier systems with no credible operating date.
- Already exists
- Solar-powered spacecraft
- Weakest link
- heat rejection, radiation, launch/assembly cost, maintenance, power-beaming economics, ground infrastructure, and debris
- Classification
- Operational Now / In Demonstration / Active Development / Plausible Frontier / Imagination Boundary
