What this call funds

Expected Outcome:

The strategic objective of this topic is to develop capabilities to ‘Act in Space’ through demonstrating in space a pilot mission by 2030 related to ISOS. The envisaged ISOS pilot mission shall provide the necessary seed components for a future service infrastructure, available to the European in-space ecosystem (including the EU assets), driving the generation of a new in-space economy, providing enhanced in-orbit technology demonstration and maximising EU technology non-dependence.

This pilot mission will largely contribute to ensure EU’s freedom of action in space, increase the resilience and protection of EU assets in space and foster the development of the new in-space economy. A pioneering and a novel mission concept, which is unique compared to other initiatives among all space-faring nations is envisaged. The mission will build on previous R&I with an operational mission concept, focusing on application and service demonstration, with a concrete view to commercial and governmental usage. The detailed mission concept has been derived in close coordination with EU Member States and EEA countries through a dedicated Pilot Mission Advisory Group (PMAG).

This topic addresses the validation of the developed ISOS4I mission components in an integrated ground test. The setup will integrate all mission components in a suitable test environment, including necessary simulation and control of the engineering/qualification models. Furthermore, the topic will address the qualification and verification of the Universal Service Interface (USI) solution(s) identified through the consolidation work done in the CSA[1]. Moreover, the activity shall support public outreach activities for the ISOS4I pilot mission.

These are Bemzu's estimates from the call's structure (the number of stages and whether a consortium is required) not figures published by the Commission. Only the co-financing share is read from the call itself.

Where these conditions come from

Two kinds of row. Most are the sentence we read the condition from, quoted out of the call itself. Some say plainly that they are not a quotation but the programme's own rule for this type of action, the EU portal publishes a table of contents where the conditions should be, so for a Research and Innovation Action the rate comes from the rulebook rather than from the fiche.

ConditionQuoted from the call, or the rule behind it
Consortium sizeNot quoted from this call — Research and Innovation Actions under the Horizon Europe rules are at least three independent legal entities from three different Member States or Associated Countries, at least one established in a Member State.
Funding rateNot quoted from this call — Research and Innovation Actions under the Horizon Europe rules are funded at 100% of eligible costs for every participant.
MaturityScope: To tackle the above expected outcomes, the following R&I actions should be addressed in the shortest possible timeframe taking into account the provided technical annex[3]: • Supporting the ISOS Pilot mission detailed mission and system design, demonstrating in an integrated ground test (TRL6
