Solar energy availability can change operating inputs but does not erase those costs. Suncatcher’s launch-price analysis is explicitly conditional and incomplete as a total economic study; its projected future launch input must not be presented as a current quote. A fair terrestrial comparison uses the same accepted workload, quality and service targets. Space-generated data reduction and ground-user interactive services can produce very different communication costs. A useful scenario identifies the assumptions that allow its budget to close and any unresolved constraint that prevents a useful service.\n\n1.  Choose a concrete workload and matching terrestrial service baseline.\n2.  Close energy, thermal and link budgets before assigning sustained useful throughput.\n3.  Include complete initial and recurring costs with a consistent lifetime and accounting boundary.\n4.  Apply availability and accepted-result criteria without double-counting utilization already in measured throughput.\n5.  Vary uncertain launch, mass, lifetime and service assumptions and identify where the preferred option changes.\n\n## Science and assumptions\n\n### Launch-only annualization\n\n$$\nC_{\\mathrm{launch}}=\\frac{p_{\\mathrm{launch}}m}{L}\n$$\n\nLaunch-only annualized cost per payload kilowatt is launch price per kilogram times mass per kilowatt divided by useful years.\n\nSymbols and units\n\nC\\_launch\n\nLaunch-only cost annualized per payload kilowatt\n\ncurrency/(kW·year)\n\np\\_launch\n\nLaunch price per delivered kilogram under the selected scope\n\ncurrency/kg\n\nm\n\nLaunched mass per payload kilowatt\n\nkg/kW\n\nL\n\nUseful operating life for the annualization\n\nyears\n\nplaunch is currency/kg, m kg per payload kW and L useful years; result is currency/(payload kW·year).\n\nAssumptions Only launch amortization; excludes spacecraft, ground, operations, financing, failures and other lifecycle costs.\n\n## Engineering example\n\nSynthetic $500/kg, 20 kg per payload kW and five-year life yields $2,000/(payload kW·year) for launch alone. Doubling mass doubles that component; no token rate or total ownership cost follows from it.\n\n## Distinctions and tradeoffs\n\nComparing launch-only annualized cost to a terrestrial electricity bill is not a full system-cost comparison.\n\nAn attractive launch assumption can be outweighed by ground-data traffic, short lifetime, low availability or expensive thermal support.\n\nAI workload fit determines useful results; no universal dollar-per-kW or MW-to-token factor can compare all terrestrial and orbital systems.\n\n## Specifications and interfaces\n\nEconomic boundary\n\nComplete lifecycle per accepted result\n\nLaunch-only cost is a component, not total cost of ownership.\n\nScenario status\n\nConditional assumptions and sensitivity\n\nFuture prices and fleet-scale availability require explicit uncertainty.\n\n### Interfaces\n\nPhysical and operational budgets Input\n\nMass, power, thermal, links, lifetime and service quality\n\nConditional service economics Output\n\nCost per accepted result and unresolved bottlenecks\n\n## Check your understanding\n\n### Which denominator makes an orbital and terrestrial comparison meaningful?\n\n1.  Only nameplate electrical power\n2.  Only peak accelerator FLOPS\n3.  Equivalent accepted workload results under matched conditions\n\nAnswer and reasoning\n\nEquivalent accepted workload results under matched conditions\n\nUseful service depends on quality, latency and availability, so identical power or peak arithmetic need not deliver identical outcomes.\n\n## Evidence and scope\n\nThe example is synthetic. The source’s mid-2030s launch-price projection is forecast evidence, not a current market price or a completed feasibility demonstration.\n\nNo current calculator directly models this lesson’s main mechanism. Use the library for related bounds while retaining their stated omissions.\n\n## Sources\n\n-   [Towards a future space-based, highly scalable AI infrastructure system design, v2](https://arxiv.org/html/2511.19468v2)\n\n[Published lesson data](https://semiaifoundry.com/ai-atlas/lesson-data/orbital-lifecycle-economics-5e1c75f1d1c56ba2.json) · [Atlas releases and licensing](https://semiaifoundry.com/ai-atlas/licenses.html)\n\n## Continue exploring\n\n### Foundations\n\n-   [Launch, replacement and end-of-life mass](https://semiaifoundry.com/learn/atlas/orbital-replacement-mass/)\n-   [Orbital optical links and contact budgets](https://semiaifoundry.com/learn/atlas/orbital-link-contacts/)\n\n### Related lessons\n\n-   [Orbital computing evidence ladder](https://semiaifoundry.com/learn/atlas/orbital-evidence-status/)"
