Successful science communication: A case study, Ars Technica
"It is no secret that, in general, i.e. outside of dedicated science reporting venues and the occasional medical report on the evening news, the scientific community does a craptastic job of communicating with the general public. While I think we at Nobel Intent do it admirably, we are but an infinitesimal sliver in the pie of science. A report that appeared in a recent edition of the Proceedings of the National Academy of Sciences highlights a case study of effective science communication and deconstructs it to show what parts may be generally applicable to other areas of science."


In the science, planetary, astronomy and earth observations areas, NASA does a pretty good job on communications. Hubble and the past several Mars missions are good and positive examples.
Within Human Spaceflight, communications is an area that is not taken seriously. They bring in people with no background in NASA and none in communications, and make political assignments, thinking its probably the least important area to pay attention to.
Shuttle is passable but barely so, and then only because NASA Public Affairs highlights launches.
ISS is for all practical purposes non-existent to the public. Few inside or outside of NASA seem to understand what it is, how it functions, or what its for.
The Constellation people never seemed to know for themselves what their goals were, and they certainly never succeeded in communicating anything cohesive to others.
