Wales no longer a unit of measurement

If a press release from the European Space Agency is anything to go by, the continent’s masters have de-recognised Wales as a fundamental unit of geography (e.g., “an area the size of Wales”).

The once noble but now old and decidedly shabby colony of England has been replaced by bright and bushy-tailed Slovenia when comparing 20,000 square kilometres of like with unlike, in this case a Martian canyon the floor of which lies nine kilometres below the surrounding plain.

This is a most grievous error, as observed features of the Melas Chasma look remarkably like Blaenau-Ffycin-Ffestiniog when viewed from the heavens.
