I don't know why NASA TV lets those horrible hums at 1.33KHz and 2.66KHz out into the world, but I just filtered them out on my Mac using iZotope and Audio Hijack. 😬
@jsnell In general I'm struck by the relatively low production value, especially compared to something like a SpaceX broadcast. NASA has such a great opportunity to capture people's attention and a few graphics and better commentary would go such a long way.
