Since the launch has been postponed again, I suggest you tune to the HQ3 channel on NASA tv, and watch that "Videofile" show. They run it several times a day. They're showing some pictures and time-lapse video of the huge radio telescope at Goldstone. Recently NASA spent a ton of money to do a renovation on it. The thing is 230' diameter, I believe. It's just amazing to me, to see this thing. The video is probably available on the NASA website too, but I didn't try to locate it there.
