They are dubbed. And the sbs ones I used to watch were dubbed too. I suspect the reason the NHK news is raw is too much of a pain to add subs/dubs for every day. Especially since most people that would watch them are most likely speakers of Japanese anyway. Although I do like watching the russian news...
Astro is dubbed as well (I can't stand this version of Astro). Fruits basket and that other one are dubbed too.
IMO if a dub is well done, then I don't mind watching it dubbed. I watched Gurren Lagann Dubbed and thought it was ace as Kamina was excellently done. I prefer the english dub of Space Ship Yamato (Starblazers) as the main bad guy (Desslar) sounds like a truly evil dandy in the English version, as opposed to 'generic evil powerful male leader' in Japanese.
