ESA Explains Delay in Signing MaiaSpace Launcher Challenge Contract

The European Space Agency (ESA) has revealed that MaiaSpace’s decision to pursue a different funding arrangement from its competitors has complicated negotiations over its European Launcher Challenge contract.

Speaking during an ESA media briefing on 22 October, ESA Director of Space Transportation Géraldine Naja explained that MaiaSpace was the only one of the four companies to opt for support through launch service contracts.

“MaiaSpace is the only one of the challengers who has chosen to be supported in terms of launch contracts rather than in technical development,” Naja explained.

Under the European Launcher Challenge, funding was allocated through two components. Component A provides funding to subsidise launch service contracts, while Component B provides co-funding for the development and demonstration of upgraded launch vehicle capabilities.

During ESA’s 2025 Ministerial Council meeting in Bremen, member states committed €902.16 million to the European Launcher Challenge. MaiaSpace itself secured commitments totalling €183.4 million, all of which were allocated to Component A.

By contrast, the other three companies secured the majority of their funding commitments under Component B. PLD Space received commitments of €132.23 million, Isar Aerospace €173.8 million and Rocket Factory Augsburg (RFA) €175.21 million under the component. Each secured less than €37 million under Component A, with RFA receiving just €15.3 million.

On 27 August, ESA announced that it had signed European Launcher Challenge contracts worth a combined €543.6 million with the other three companies. Isar Aerospace secured the largest contract at €197.8 million, followed by RFA at €186.9 million and PLD Space at €158.9 million. At the time, the agency stated that “the contract award process with MaiaSpace is nearing completion and expected to resume in the coming weeks.”

During her 22 October comments, Naja explained that while MaiaSpace’s preference for launch-service contracts had made negotiations “a little bit more sophisticated”, the contract’s signing was a “question of days.” That was, however, three weeks ago, and ESA has yet to publicly announce that the contract has been signed.
