NASA TV Live stream: https://www.youtube.com/watch?v=21X5lGlDOfg
This one has commentary. https://youtu.be/0_vyZiVxEEo
FranLab and EEVBlog did a livestream together, there also was done by the Angry Astronaut, as well as one by the Everyday Astronaut. I'd say if you're on HN there's a decent chance you know at least one of these channels already, Youtube just isn't doing a good job of notifying subscribers to livestreams :)
Everyday Astronaut has some good coverage
Looking at Youtube now, there are clips from some feeds, so it was being streamed somewhere.
