I’m was very pleased with ISDC 2009. It was well organized and there were a lot of very good talks by various presenters at the different tracks during the conference. The kids space station design contest (NSS-NASA-and I forget the 3rd organization)  inspired a lot of grade school teams from around the world!

My presentation, “Stealth, Invisibility and Deep Space Radiation Shielding” was very well attended. There were more than 40 in the audience, and many, many questions. I’ve posted the presentation and video at iSETI LLC’s white papers.
