The European Space Agency (ESA)

The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.

Formed in 1973, when a Ministerial Conference in the Hague approved a highly ambitious space programme to carry the European space effort into the new millennium.

Since the last ESMATS, Ariane 5 successfully completed its 100th launch and has an order book stretching into 2022. BepiColombo, Metop-C, EDRS_C, CHEOPS and Solar Orbitor have all been successfully launched. XMM-Newton has successfully completed 20 years in orbit and continues to provide ground breaking science; its sister spacecraft INTEGRAL, launched in October 2002 is also still operational and SOHO launched in December 1995 has completed  25 years of successful sun observation and comet spotting. The Cluster II satellites launched in the summer of 2000 are also still operational after 20 years in orbit.
