euesa1-8, Exercise 3: The weather forecast chain

Model answer:

Three kinds of organisation: ESA, which develops and builds the Meteosat and MetOp satellites with industry; EUMETSAT, the separate European weather-satellite organisation, which operates them; and a national weather service such as the Met Office, which processes the data into forecasts. The EU also uses the data.

Space is rarely "one thing" because each stage, from funding to building, operating and using, is often done by a different organisation with different members and rules, so no single body is the answer to "who does space in Europe".
