The last mission to the Hubble Space Telescope (HST) is about to roar into space. Space Shuttle mission STS-125 will be the final mission to update the HST. It will also be the final mission where planned non-ISS EVAs are undertaken. The Orion Crew Vehicle isn't suited for EVAs like this, so we'll probably never see these repair missions again. Here are a few resources that cover the launch and preparations LIVE: Nasa's own NASATV: http://www.nasa.gov/ntv but that isn't of very good quality video-wise. A much better alternative is http://www.spacevidcast.com/ which offers 720p quality live streaming. Great about this one is that with the ustream.tv iPhone app you can actually watch this on your iPhone too, and also participate in the chat! On regular TV there's Discovery Channel that will broadcast the launch and preps live from 19.30 CEST on!
