I'm guessing this must be a SpaceX spacewalk? I had not heard anything about it either. I would check the amateur radio frequencies and bands for any kind of relay of the audio like they did on the space shuttle. I guess it just depends if the frequencies are available, in the clear, and something we can monitor. I was thinking about this latest private manned space flight the other day wondering if the traffic would be in the clear or encrypted since this is the private sector and not NASA.
