My unsolicited advice to the folks on this thread that were moved by todays launch: make time to travel to Florida and see one of these launches in person. If you have kids take them with you.
Years ago I took some time out of a very busy schedule to see STS-130, the last shuttle night launch. I've always been a space nerd but I wasn't prepared for how seeing, hearing and feeling a launch in person was so different than watching it on a rectangle. And I wasn't prepared by how profound the experience would be. It was one of the best on-the-whim-of-the-moment decisions I've made in my life. Do it. I guarantee a lump in your throat.
