Love watching this stuff - brings me back to my childhood when they'd roll the tv's into our class rooms at school so we could watch the NASA launches.
LOL, I sure remember the teacher rolling in the "media cart" in the 80's. It always meant it was going to be a good day! My wife and I are both fans of anything space related. We were just in the area of the Kennedy Space Center but had no time for a visit, we were bummed.
