NASA has it's own radio station! http://www.thirdrockradio.net/
The music is mainly New Rock and Alternative. JJJ listeners will enjoy it I think.
And of course you get all the latest Space News.
You can also download the app to listen on your smart phone or iPhone.
Thanks for that JJJ. They have been playing some cool stuff and yes I am a JJJ fan and they seem to play similar stuff.
Aussie DAB and internet station "Radar radio" is another similar to JJJ and Third rock.
