I know, I know, it is not exactly ham radio, but look at it this way: electromagnetic waves from far, far away! REAL DX. And some very cool gear to receive the signals. And some recent repair and modification work... So you see, this is really not so far afield after all.
I've been a big fan of the Hubble Space Telescope for a long time. When I was closer to the equator (in Santo Domingo) sitings of the HST were quite common. I'm glad to see that the recent repairs and mods worked out so well. Here is a really nice video on the new and improved Hubble: Hubble Space Telescope Video
