In 1975, a convention was concluded at diplomatic and ministerial level to set up one ‘European Space Agency’, effectively merging ESRO and ELDO. The new Agency’s remit not only covered launchers and science but also operational space applications systems such as telecommunications satellites.
Following the entry into force of the ESA Convention in 1980, the founding members were joined by Ireland later the same year, then Austria and Norway (1986), Finland (1995), Portugal (2000), Greece and Luxembourg (2005), Czech Republic (2008), Romania (2011), Poland (2012), and Estonia and Hungary (2015). The latest to join was Slovenia in 2025, becoming the 23rd Member States.
