From the NASM
I have known Roger since he was at NASA. We have disagreed, but he's been an invaluable resource to me as I took my first steps into space history. I didn't realize until now that he had a blog, though. In this entry, he discusses a panel he's moderating: "a discussion on Capitol Hill, Rayburn 2325, on Friday, June 15, 2012, 10 a.m. EDT, about “Commercialization of Space Travel and Human Participation in Space Exploration." Near and dear to my heart - if I was in Washington, I'd head on over.
He also has an interesting entry here: review of a new book on a very important force in space exploration (at least it used to be), Soviet robotic probes.
