European Launcher Development Organisation

The European Launcher Development Organisation (ELDO) is a former European space research organisation. It was first developed in order to establish a satellite launch vehicle for Europe. The three-stage rocket developed was named Europa, after the mythical Greek goddess. Overall, there were 10 launches that occurred under ELDO's funding. The organisation consisted of Belgium, Britain, France, Germany, Italy, and the Netherlands. Australia was an associate member of the organisation.

Initially, the launch site was in Woomera, Australia, but was later moved to the French site Kourou, in French Guiana. The programme was created to replace the Blue Streak Missile Programme after its cancellation in 1960. In 1974, after an unsuccessful satellite launch, the programme was merged with the European Space Research Organisation to form the European Space Agency.
