This year marks the 50th anniversary of the founding of the European Space Agency (Esa). It has launched spectacularly successful missions, but is different to other space agencies which generally represent one country. Esa is funded by 23 member states and also has cooperation agreements with nations such as Canada.
Esa operates cutting edge spacecraft designed to monitor the Earth, as well as space telescopes that study the distant cosmos. It has launched robotic spacecraft to other planets and to objects such as comets. It is also involved in human spaceflight – training European astronauts to work on the International Space Station (ISS).
