I absolutely agree that they should immediately release data & images for more technically inclined section. However the reason for speeches is entire nation is watching this event across all age group, most of them don't understand technical things, I would say even image of moon surface wont connect to most of them. Basically speeches is the way to connect & artists impression images. To give some example, people thing entire rocket goes to moon, one of the politician was wishing "passengers" on the spacecraft, reputed news channel claiming "breaking new" that there wont be delay in landing as if we can push breaks like in car or traffic on the way. So you get the point, to connect to masses they are speaking in language that everyone understand
