What the study found
The paper argues that European space institutions developed through fragmentation, with separate launcher and satellite programs rather than a single unified system. It presents the 1975 merger of ELDO and ESRO into ESA as part of a history shaped by national interests, political compromises, and institutional overlap.
Why the authors say this matters
The authors conclude that this history helps explain Europe’s continuing difficulties in space exploration and the uneasy relationship between ESA and the EU. The study suggests that the case also challenges functionalist approaches in international organizations law, because political and economic factors played a major role in shaping ESA’s evolution.
What the researchers tested
The paper uses a historical case study of the merger between the European Launcher Development Organization (ELDO) and the European Space Research Organization (ESRO) into the European Space Agency (ESA) in 1975. It analyses this merger to examine how European space institutions were formed and how that case speaks to broader approaches in international organizations law.
What worked and what didn't
According to the paper, the original vision of a unified scientific effort like CERN did not hold, and European space efforts were split into launcher and satellite programs. The paper says ELDO’s technical failures and ESRO’s financial constraints showed the costs of this fragmentation. It also states that the merger did not remove the underlying divisions, which persist in the ESA-EU relationship.
What to keep in mind
This summary is based only on the abstract, so detailed evidence, examples, and limitations are not available here. The paper’s claims are presented as an argument from one historical case study, and the abstract does not describe other cases or any formal comparison.
