Thanks Craig, I'll have to have a listen.
I used to listen to AstronomyCast all the time when I was driving to work, but got out of the habit lately. It's a great podcast.
They also had an "Ice in space" episode a few months back, but it was about comets
I'm a big fan of Fraser and his work at Universe Today. It was my inspiration many many years ago when first starting IceInSpace.
