Chewing this over this AM I think the problem with the coverage is traditionally you had the networks between NASA/the PAO and the viewer. That meant sometimes but hopefully not too often the talking heads at NBC, BBC, ITV etc would break in to explain/illustrate a point.
That doesn't happen.now, it's often PAO in Mission control straight to viewer.
I did notice on a split screen last night that on the science room wall at one point they had the inflight image up and adjacent to it a pretty much identical computer generated view with labels...it's a shame that didn't go out on the feed occasionally.
