Quick Summary

The European Launcher Development Organisation (ELDO) was established in 1964 by seven European member states with the goal of developing a space launch vehicle for Europe. ELDO was a precursor to the European Space Agency (ESA), which was formed in 1975 through the merger of ELDO and the European Space Research Organisation (ESRO). While ESRO was successful in science missions, ELDO struggled to design and launch a European rocket. The ESA, with 22 member states, has since developed reliable launch vehicles like the Ariane series, providing Europe with independent access to space and a significant role in the commercial launch industry.12
