Don't forget that today is the 40th anniversary of the Apollo 11 moon landing, and several great websites are doing live coverage to the second. The landing anniversary is at 4:10 pm EDT (1:10 pm PDT), and the walk is at 10:10 pm EDT (7:10 pm PDT).
We Choose the Moon (which I mentioned a few days ago) continues to live stream audio and CG renderings of the entire mission, and is a great place to be this afternoon.
Also, Jason Kottke has set up a recreation of the Apollo 11 live TV coverage with Walter Cronkite. Yes, you could watch it any time on YouTube, but as Jason notes, doing it live best fits the spirit of the original event:
I've watched the whole thing a couple of times while putting this together and I'm struck by two things: 1) how it's almost more amazing that hundreds of millions of people watched the first Moon walk *live* on TV than it is that they got to the Moon in the first place, and 2) that pretty much the sole purpose of the Apollo 11 Moon walk was to photograph it and broadcast it live back to Earth.
