Hanselman has been on a tear of late with his podcasts but one series in particular I’ve enjoyed is a series of folks who in some way are connected with NASA or the space program. Even though I was a kid who was geek enough to want to become an astronomer, often fondling worn out pages of a Space Atlas , I think just about anyone will enjoy these conversations.

Holly Griffith – former space shuttle and current space station worker (Space Tweep Society).

Mark Powell – senior software engineer at Jet Propulsion Laboratories

Paul Lutus – there are dudes and there are dudes. Paul Lutus is a dude.
