Paris, France | 15 August 2026 – Novaspace's latest In-Orbit Services Markets report projects that emerging in-orbit services will generate approximately $3 billion in cumulative service revenues over the next decade, highlighting the early development stage of a sector poised to support next-generation satellite constellations including LEO platforms operated by SpaceX Starlink, Amazon Project Kuiper, Eutelsat OneWeb, and Telesat.

The market forecast underscores growing demand for orbital refuelling, debris removal, satellite servicing, and in-situ manufacturing—capabilities increasingly critical as mega-constellations expand and regulatory pressure on space debris intensifies across UK, EU, and global jurisdictions.

Understanding In-Orbit Services: Definition and Scope

In-orbit services (IOS) encompass a range of activities performed by robotic or crewed spacecraft on or near operational or defunct satellites in orbit. These include:

  • Propellant replenishment: Extending satellite operational life by transferring fuel to on-orbit assets.
  • Active debris removal: Capturing, de-orbiting, or repositioning non-functional spacecraft and launch vehicle stages.
  • Satellite servicing and repair: Upgrading avionics, replacing components, or extending mission duration.
  • On-orbit assembly: Constructing large structures or antenna arrays from modular components launched separately.
  • In-situ resource utilisation (ISRU): Mining or processing materials in orbit for downstream use.

Unlike traditional satellite operations—where end-of-life deorbiting relies on onboard propellant—IOS introduces a secondary economy where specialised service vehicles approach, dock with, and perform mechanical or chemical tasks on spacecraft that may belong to different operators or constellations.

The Novaspace Report: Key Projections and Market Drivers

Novaspace, a European space analysis firm, estimates cumulative service revenues of approximately $3 billion across the 2026–2036 period. The projection reflects several interconnected trends:

Mega-Constellation Growth and Propellant Economics

SpaceX's Starlink constellation has deployed over 6,000 satellites as of mid-2026, with Amazon Project Kuiper ramping production to reach operational status by late 2026. Eutelsat OneWeb and Telesat Lightspeed are in advanced development phases. Each constellation requires periodic propellant replenishment to maintain orbital position and extend operational life beyond initial design margins.

Traditional end-of-life protocols assume satellites carry sufficient fuel for final de-orbit burns. However, commercial and regulatory incentives—including Ofcom orbital debris mitigation guidelines and ESA Space Debris Mitigation Guidelines—increasingly favour keeping operational spacecraft aloft longer if propellant can be supplied externally. This economic shift underpins demand for on-orbit refuelling services.

Regulatory Pressure on Space Debris

The UK Space Agency, Ofcom, and the European Union Space Programme (EUSP) have strengthened orbital debris requirements. Ofcom's licence conditions for satellite operators now require end-of-life plans compliant with IADC (Inter-Agency Space Debris Coordination Committee) standards, including 25-year deorbit targets for LEO assets. Active debris removal services reduce collision risk and support compliance with upcoming EU Space Regulation orbital debris provisions.

Long-Duration LEO Operations and Servicing Economics

As LEO constellations mature, the cost-benefit calculation shifts. Launching replacement satellites becomes comparable to or more expensive than performing on-orbit repairs or fuel transfers. Service vehicles designed for multiple missions across different constellation operators create economies of scale, gradually lowering per-mission costs and expanding the serviceable market.

UK and European In-Orbit Services Capabilities: Current Status

UK Space Sector Positioning

The UK Space Agency has identified in-orbit servicing as a priority growth area within the National Space Strategy. UK-based companies including Tyvak (UK subsidiary of Axiom Space), Geoptic, and emerging ventures are developing servicing platforms, while established contractors such as Thales Alenia Space operate European research programmes in autonomous rendezvous and docking (AR&D) technologies.

However, UK industrial capacity in operational servicing vehicles remains nascent. No UK-based company has yet deployed a commercial in-orbit servicing mission, though government support through the Space Growth Partnership and grants from the Innovation Hub aims to accelerate capability development.

European Leadership: France and Germany

The European Space Agency (ESA) funds multiple in-orbit servicing demonstration projects, including Copernicus-linked initiatives and dedicated R&D contracts. French companies Clearspace and ArianeGroup, and German firms including OHB SE, are advancing debris removal and servicing concepts with ESA co-funding and commercial venture backing.

Clearspace's planned demonstration mission (originally scheduled for 2026, though subject to programme delays) aims to demonstrate capture and controlled de-orbit of a Vespa upper stage—marking a potential inflection point in the commercial IOS sector. Such demonstrations, even if delayed, validate supply-side interest and draw investment capital toward the sector.

Market Segmentation and Revenue Distribution

The $3 billion cumulative projection spans multiple service categories, with different maturity curves:

Propellant Resupply (Early Mover, Highest Near-Term Volume)

On-orbit refuelling is technically simpler than debris removal and requires fewer autonomous capabilities. Early commercial missions are expected to focus on refuelling high-value GEO assets—communications satellites with 15+ year design lives—where propellant margins are tight. LEO constellations will follow as servicing infrastructure matures.

Revenue outlook: Estimated $800 million to $1.2 billion over the decade, driven by mid-2020s launches of first commercial refuelling vehicles and gradual adoption across constellation operators.

Active Debris Removal (Regulatory and Insurer Pressure)

Insurance underwriters and orbital-use licensing authorities increasingly mandate debris mitigation. Novaspace's forecast incorporates growing demand for removal services targeting high-risk objects in critical orbital regions (e.g., near 900 km altitude, a Starlink-heavy zone).

Revenue outlook: Estimated $1.0 billion to $1.5 billion, contingent on regulatory mandates and insurance premium incentives for debris remediation.

Satellite Repair and Upgrade (Mid-Term, High-Value Niche)

Crewed or large autonomous servicers capable of component replacement or avionics upgrades serve premium communications or Earth observation payloads. This segment remains immature but offers highest per-mission revenue.

Revenue outlook: $300 million to $500 million, concentrated in 2030–2036 as crewed or heavy-lift servicing vehicles enter operational phase.

On-Orbit Manufacturing and ISRU (Speculative, Long-Tail)

In-situ resource utilisation—particularly water extraction from asteroids or manufacturing in microgravity—remains largely experimental. Novaspace's $3 billion projection includes modest allocations for demonstration projects and initial commercial operations, reflecting high technical risk and uncertain demand.

Amazon Project Kuiper and the Servicing Imperative

Amazon's Project Kuiper constellation, expected to reach initial operational capability by late 2026, will inherit the same servicing economics facing Starlink. Kuiper's licence conditions, granted by the FCC, require 25-year deorbit compliance, aligning with international standards.

As Kuiper deploys thousands of satellites into LEO, the constellation will become both a customer for in-orbit services (seeking propellant resupply and repairs) and a potential ecosystem participant if Amazon invests in proprietary servicing infrastructure. Industry observers expect Kuiper to follow Starlink's model of initially absorbing end-of-life costs but gradually adopting third-party servicing if economics improve.

Regulatory Framework and UK Ofcom Oversight

Ofcom's recent guidance on orbital debris mitigation and licence modification procedures now explicitly address in-orbit servicing as a compliance tool. UK satellite operators—including those supporting Starlink ground stations or terrestrial infrastructure—must demonstrate:

  • Adherence to IADC collision avoidance standards.
  • End-of-life plans aligned with 25-year deorbit targets (or variance with justification).
  • Tracking and notification protocols for servicing activities affecting licensed orbits.

Ofcom's orbital debris mitigation guidance (2023) provides the regulatory foundation, with updates anticipated in 2026–2027 to clarify servicing operator licensing and third-party liability frameworks.

Technical Challenges and Deployment Barriers

Despite optimistic market projections, several technical and commercial hurdles constrain near-term growth:

Rendezvous and Docking Autonomy

Most LEO satellites (particularly Starlink and Kuiper units) were not designed with standardised docking interfaces. Servicing vehicles must employ autonomous computer vision and AI-driven navigation to approach, match orbital velocity, and contact uncooperative spacecraft—a capability still in demonstration phase.

Operator Liability and Insurance

Third-party servicing introduces collision and property damage risks. Operators and underwriters must develop standardised liability apportionment and insurance products, a process that may slow commercial adoption until precedent is established.

Regulatory Approval for Debris Removal

Active debris removal—particularly capturing or de-orbiting objects from other operators—requires explicit international coordination and permission frameworks. Current space law remains ambiguous on removal of non-functional objects, creating legal friction despite technical feasibility.

Forward-Looking Analysis: Market Maturation and UK Opportunities

The $3 billion decade projection represents conservative consensus, with significant upside if regulatory mandates accelerate or constellation operators adopt servicing more rapidly than baseline forecasts assume. Several scenarios merit consideration:

Bullish Case: Regulatory Mandate Scenario

If the UK, EU, or international bodies mandate active debris removal for high-risk orbits (e.g., Starlink/Kuiper dense zones near 550 km), service demand could exceed Novaspace's baseline, pushing market revenues toward $4.5–5 billion. This scenario reflects growing political will to enforce debris mitigation but remains uncertain pending formal rulemaking in 2027–2028.

Base Case: Organic Market Growth

Constellation operators gradually adopt third-party refuelling and repair services as commercial providers establish track records. Market grows to $2.8–3.2 billion, with propellant resupply dominating volume and debris removal following as regulatory pressure increases. This aligns with Novaspace's central projection.

Conservative Case: Technology and Cost Delays

If autonomous servicing technologies advance more slowly than anticipated or if insurance/liability frameworks remain unresolved, commercial deployments could lag 2–3 years, compressing the decade's revenue window and reducing cumulative totals to $1.8–2.2 billion.

UK Industrial Strategy Implications

The UK Space Agency and Department for Science, Innovation and Technology have signalled commitment to in-orbit servicing via the Space Growth Partnership and targeted R&D grants. To capture share of the emerging $3 billion market, UK firms must:

  • Accelerate autonomous rendezvous and docking demos: Partner with ESA or international consortia to validate technologies by 2027–2028.
  • Address liability and insurance frameworks: Engage Ofcom, Lloyd's of London, and international bodies to develop standardised risk models.
  • Target propellant resupply first: Lower technical barrier and clearer near-term demand from GEO and LEO operators.
  • Develop modular servicing payloads: Design mission-agnostic tools and platforms to reduce per-mission development costs and improve addressable market size.

Conclusion: In-Orbit Services as Constellation Support Infrastructure

Novaspace's $3 billion in-orbit services market projection reflects maturing recognition that mega-constellations like Starlink and Kuiper are not one-off deployments but evolving orbital ecosystems requiring ongoing maintenance, refuelling, and debris management. The forecast is neither exuberant nor pessimistic—rather, it signals an emerging but still-nascent market where technical capability, regulatory frameworks, and commercial incentives are aligning gradually.

For UK operators, infrastructure providers, and manufacturers supporting LEO connectivity, in-orbit services represent both opportunity and regulatory imperative. As Starlink and Kuiper operations mature, demand for servicing capabilities will grow, creating roles for UK-based suppliers in propellant logistics, autonomous systems, and mission assurance. Regulatory clarity from Ofcom and alignment with EU Space Regulation will be critical enablers.

Over the 2026–2036 period, cumulative revenues of $3 billion are credible but not foreordained. Market realisation depends on timely technology demonstrations, resolution of liability and insurance frameworks, and deliberate policy decisions by constellation operators to adopt third-party services rather than absorb end-of-life costs internally. The UK space sector's ability to participate meaningfully in this market will reflect both industrial investment and strategic alignment with constellation operators' long-term servicing plans.
