Purpose of the Grant

The topic finances the detailed design and technology maturation of the logistics module of the EU’s *In-Space Operations & Services (ISOS) pilot mission* to be launched by 2030. The logistics component must:


* Transport satAPPs payloads and propellant from an upper stage to the HOST platform.

* Provide automated docking, fluid transfer and plug-&-play cargo handling compatible with circular-economy spacecraft architectures.

* Interface seamlessly with the servicing, HOST and satAPPs elements being prepared under parallel Horizon 2025 calls.


Successful completion will secure Europe’s strategic freedom to “Act in Space”, reinforce non-dependence, and seed a commercial in-orbit logistics market for both institutional and private customers.


Budget Logic

The call foresees one flagship grant. A credible budget should allocate:


* ~45 % to detailed system & mission engineering (including interface working groups with other ISOS projects)

* ~30 % to critical technology maturation & breadboarding (docking mechanisms, propellant transfer pumps, modular cargo bays)

* ~15 % to in-orbit demonstration preparation and verification planning

* ~10 % to exploitation, business modelling, standardisation & dissemination


Costs are reimbursed at 100 % of eligible direct costs + 25 % indirect (Horizon standard). Consortium partners may combine additional national / ESA co-funding, but *double funding must be avoided*.

🇪🇺 Strategic Advantages

EU-Wide Advantages & Opportunities for “ISOS Pilot Mission Detailed Design – Logistics Component”


1. Single Market Access

Pan-European Customer Base: Successful maturation of in-orbit logistics will unlock a unified market of >450 million end-users (institutional, commercial, security) that rely on satellite services for navigation, Earth observation, GovSatCom and IRIS².

Upstream–Downstream Multiplier: Every €1 invested in launcher & on-orbit logistics typically generates €4–€6 in downstream applications. The grant therefore de-risks private investment in the wider EU space data economy.

Early Anchor Demand: ESA, EUSPA and national space agencies already plan flight opportunities for in-orbit servicing; winning this RIA positions the consortium for framework contracts across the entire Single Market.


2. Cross-Border Collaboration & Knowledge Exchange

Mandatory Multinational Set-up: The topic explicitly requires balanced Member State/Associated Country participation and cooperation with parallel topics 21, 22 & 24, ensuring cross-border technology transfer (e.g. German electric propulsion + Italian robotic arms + French cryogenic valves).

Mobility of Talent: Horizon Europe rules enable seamless researcher mobility via secondments; SMEs can embed experts from leading labs (DLR, ONERA, ISQ, SINTEF) without work-permit hurdles.

Standardisation Forums: Joint work on docking and propellant interfaces feeds directly into CEN-CENELEC & ESA ECSS standardisation committees, accelerating EU-wide adoption.


3. Alignment with Core EU Policies

Open Strategic Autonomy: Reduces reliance on non-EU providers for critical on-orbit logistics, fully in line with the STEP Regulation and the EU Observatory on Critical Technologies.

EU Green Deal & Circular Economy: Modular, reusable “plug-and-play” satAPPs contribute to orbital resource efficiency and debris mitigation—key objectives under the Sustainable Products Initiative.

Digital Europe & AI Act: Highly automated rendezvous/docking and digital twins leverage EU cloud-edge infrastructures and comply with forthcoming trustworthy-AI requirements.

Security Union: Enhances resilience of EU assets (Galileo, Copernicus, IRIS²) and supports the EU Space Strategy for Security & Defence.


4. Regulatory Harmonisation Benefits

Unified Export Control Environment: Participation is limited to EU/EEA/like-minded states, greatly simplifying ITAR-free supply chains.

Common Safety & STM Rules: Outputs will feed into the upcoming EU Space Traffic Management (STM) Regulation, providing first-mover compliance advantage.

IPR Clarity: Horizon Europe MGA offers predictable background/foreground IP clauses, easing cross-border licensing once the logistics module is commercialised.


5. Access to Europe’s Innovation Ecosystem

Testing Infrastructure: Immediate eligibility for flight-ticket IOD/IOV missions under the EU Flight Ticket Initiative; access to European Large System Testbeds (ESTEC, ZARM Drop Tower, ESRANGE).

Research Excellence: Synergies with 200+ universities in the EU Space Universities Network and robotic centres funded by DIGITAL-Europe and EIT Manufacturing.

CASSINI & EIC Pathway: Post-RIA scale-up funding (up to €15 M blended finance) is available for qualifying start-ups, ensuring continuity to TRL 9.


6. Funding Synergies & Leverage

Cumulative Grants: Combination with ESA GSTP maturation contracts and national recovery funds (RRF) can raise total non-dilutive funding to >€100 M across the consortium.

Blending with InvestEU: Large-scale orbital logistics infrastructure could access guarantees/loans for manufacturing scale-up.

Structural Funds for SMEs: Regional ERDF programmes can co-finance test facilities and cleanrooms in convergence regions, spreading economic benefits EU-wide.


7. Scale & Impact Potential

EU-Wide Service Infrastructure by 2030: Logistics vehicle acts as the backbone for an AppStore-like ecosystem; once qualified, it can be integrated with Ariane 6, Vega-E and emerging micro-launchers, creating a pan-European service mesh.

Job Creation & Spill-overs: Estimated 2 500 high-skilled jobs during RIA phase, rising to 20 000 by 2035 through derivative services (refuelling, debris removal, in-situ assembly).

Global Competitiveness: A successful EU-led ISOS pilot would position Europe as the first jurisdiction with an end-to-end circular in-orbit economy, differentiating it from US and Asian competitors and opening export markets under EU trade agreements.


8. Strategic Take-Aways for Applicants

1. Showcase EU Value Chain Completeness: Map each critical subsystem to an EU supplier to underscore non-dependence.

2. Design for Interoperability: Embed ECSS & CEN standards so results are easily adopted by partners in topics 21/22/24.

3. Embed Business Models: Demonstrate demand from both EU institutional buyers and commercial constellations to leverage the Single Market.

4. Plan a STEP-compliant IP & Security Strategy: Address ownership/control questionnaire early to avoid eligibility issues.

5. Exploit Synergies: Reference complementary EU funds (EIC, ESA GSTP, national RRF) to maximise budget leverage and evaluation score on ‘Resources’.
