On November 2, human presence in orbit reaches 25 years. The International Space Station delivered a historic win. We learned how to build, crew, and operate a complex orbital facility. We proved that partnership at scale works in space.
What the ISS proved
We can assemble and sustain large platforms in low Earth orbit.We can run safe operations across disruptions in crew and cargo.We can generate value in microgravity and from Earth observation.
The ISS did its job as a first-of-kind experiment. It taught us how to build a station. It taught us how to operate one. It taught us which processes were effective and which added cost without adding value. It turned “space station” from concept into practice.
Prototype, not production
The ISS is a successful prototype. It is not a production system. Its layout, crew model, and governance optimize for learning and demonstration, not throughput. Maintenance and coordination consume too much time. As a result, the station cannot host the volume of market-facing activity that a healthy in-space economy requires.
That makes the ISS a cork in the bottle. It proved the concept, but the current configuration, method of operations, and age constrains the next phase: producing outcomes and services at scale.
Unlock the end products
Focus on outcomes, not stations. The next act should unleash products and services that improve life on Earth and build durable demand in orbit.
Biomanufacturing: tissue scaffolds, crystallography-enabled drugs, and biologics that need microgravity to form properly.
Specialty materials: optical fibers, alloys, and semiconductor structures with performance gains due to formation in microgravity.
Climate and resilience services: higher resolution Earth data for agriculture, disaster response, infrastructure, and insurance.
In-orbit services: inspection, repair, refueling, assembly, and safe deorbit as routine offerings.
Education and workforce: frequent, affordable access for universities, technical institutes, and apprenticeships.
These end products are tangible. They create measurable value that customers, taxpayers, and the public understand and will pay for. They are the reason to expand capacity in orbit.
Design targets for what comes next
To deliver outcomes, next-generation stations must hit clear targets.
Lower cost to build and operate. Drive down capex and opex per research hour.
More crew time on utilization. Reduce maintenance load. Automate routine operations.
Common standards. Docking, data, power, payload interfaces, crew safety, and logistics should interoperate.
Frictionless payload flow. Faster integration and approval cycles. Predictable cadence.
Outcome-based pricing. Buy research hours, production runs, and data products—not overhead.
Policy shift we need now
Public policy should enable a market with many providers and many users. Government should lead as an anchor customer, not as the sole proprietor.
Commit to continuity. Publish a no-gap plan so continuous U.S. presence in low Earth orbit continues post-ISS.
Fund for outcomes. Structure buys around utilization, production, and data, not platforms for their own sake.
Standardize and streamline. Set clear, minimal standards and cut latency in reviews for payloads and missions.
Broaden demand. Engage health, materials, climate, education, and national security users to expand non-NASA utilization.
Why now
The apprenticeship is complete. Demand signals are visible. Costs are falling. Delay risks a gap in presence and a loss of momentum. Moving now turns hard-won lessons into a resilient, outcome-driven ecosystem in orbit.
What success looks like by the end of the decade
Multiple stations. Interoperable systems. A higher ratio of utilization hours to maintenance hours. Measurable reductions in dollars per research hour. A diverse set of users—public and private. Continuous human presence in orbit sustained by demand for outcomes, not by a single government-run outpost.
The ISS deserves celebration and gratitude. It also deserves a worthy successor of its legacy: a productive, affordable, low Earth orbit ecosystem with many stations that delivers value on Earth.
