ESA is one of the world’s leading space exploration organizations and one of the few that is international in scope, representing 22 member states. Contrary to a common misconception, ESA is not part of the European Union and not bound by European law. In fact, ESA is not bound by any real-world law, either local or national—it’s governed only by its 130-page Convention and a set of internal regulations.
This international status grants the ESA and its staff privileges that are far superior to those afforded to its bigger sister and role model, NASA, notably the ability to maintain any internal documents as confidential.
When I lived to Austria I was appalled at how many American friends asked me about the surfing.
UN geoscheme lists it as such if you want something concrete. (Though it also puts the UK in Northern Europe, and leaves out Italy & Spain & Portugal (Southern), which I didn't mean either.)
It's a funny term. In UK use it means something like 'mainland Europe but not Russia or some former Soviet states'. It's about the bits you think of and travel to, I suppose. Although that makes it sound obvious, which it isn't, because nobody means India when they say Asia, but it's at least as much in the public psyche as anywhere else in continental Asia.
You know. "Fact" and "rigorous research".
