Hi Dfrank<br /><br />It really helps when quoting to distinguish between that you said and what the other person said. It is quite easy, and the FAQ will help you. For this reason I will give your original statements/questions in italics, my response in yellow, your responses to these in bold, and my latest comments in normal font.<br /><br /><i>Why does NASA classify images?</i><br /><br /><font color="yellow">Not to my knowledge. Please give some examples.</font><br /><br /><b>This is something I read a while back, in what place I can not remember. It was in context to the face image I believe. Someone had to sneak the photo out. It had been tucked away in a folder. If this was true it means if they would tuck one photo away they might tuck another. The classifications would be, ones we will release and ones we want. Maybe someone has a better example or maybe I dreamed that up.</b><br /><br />Lots of claims get made, the issue is whether these claims can be substantiated. NASA is legally obliged to release all data from its Mars missions. Allegations that it has not are very serious and therefore need to be backed up by evidence. Your memory of reading something about what someone claimed to have seen is not, I am sorry to say, good evidence. With reference to the “face†(which has been discussed ad nauseum on these for a) we already have multiple data sets at the full resolution of the various systems that have been sent to Mars. Even if another image was available from (say) MOC) it would not show substantially different detail to what we have seen already<br /><br /><i>Why are all the MRO images shown in grayscale</i><br /><br /><font color="yellow">Not all of them. For most purposes panchromatic is quite adequate.</font><br /><br /><b>Adequate is an opinion I guess. False color and grayscale are not adequate to me. </b><br /><br />Yes, it is my opinion. I work with satellite, airborne, and ground imagery on a near daily basis.
