The European Union has not done enough to harness the full potential of its space programs, according to a special report published April 21 by the European Court of Auditors (ECA). While the satellite-based programs Galileo and Copernicus provide valuable services and data, more efforts are needed to capitalize on the significant investment made — around €18 billion so far — and to optimize the benefits they bring to citizens and the economy.
