I guess they have a Union regulation never to mention "plasma". "Hot gas" is the closest they can get. Mentioning electrons is an advance: in the old days, x-rays were proof positive of million-degree hot gas.

"Turbulence" in gas at hard-vacuum pressure is impossible. What they are talking about is plasma fluid dynamics, charged particles in motion generating fields that affect other particles at a distance, without collisions. Anyone tackling that merits admiration.
