Has NASA's MESSENGER gone color blind? (obviously it has)
Apparently "Mercury's unseen side now seen!" is only available in those colors of gray. After all this time, and of our hard earned loot not so wisely spent, I'm actually rather disappointed in NASA's MESSENGER. Are we ever going to see the full visible spectrum scope and photographic color depth and contrast worth of our digital images, or merely as limited as to whatever gray pixels they see fit to share in B&W and of such limited DR to boot? Of course there's always the full scope of UV and IR spectrums of all those other secondary/recoil photons just outside of the human eye response (but not outside of the CCD eye), that as such could also be easily made available to us, especially if given the same eyecandy hype as accomplished on behalf of most everything else that's out of our reach. Perhaps it's just little old me deductively wondering, as to exactly why our spendy MESSENGER color imaging potential is being intentionally turned off or excluded from public review, and as to why their CCD dynamic range remains as so dismal. http://messenger.jhuapl.edu/gallery/sciencePhotos/ http://messenger.jhuapl.edu/gallery/...p?gallery_id=2 http://messenger.jhuapl.edu/gallery/...108821596M.png http://messenger.jhuapl.edu/gallery/...108826105M.png http://messenger.jhuapl.edu/gallery/...26040M_45M.jpg Thanks to our "no kid left behind" policy, as of prior to CCD camera imaging perhaps all of 0.1% of Americans even understood what photographic spectrum sensitivity and the associated DR(dynamic range) of B&W or color film even meant. Since the advent of commercial/ consumer CCD cameras and the continued dumbing down of America, I'd say that fewer than 0.0001% (that's one out of a million) of our supposedly educated population of mostly snookered and thus easily dumbfounded village idiots have so much as a freaking clue as to what either factor of spectrum sensitivity or much less that of what DR means. Of course this is perfectly good news for those of our cloak and dagger 'Skull and Bones', as well as for all those faith-based rusemasters within our NASA, and especially on behalf of those unfiltered Apollo Kodak moments that somehow never managed to get any such blue saturated images of our naked and physically dark moon like those recently accomplished by China and Japan with their quality bandpass filtered optics. Here's that other one of Venus by way of MESSENGER that's about as wussy/pastel worth of color and pathetic DR as you can possibly get, and still having just enough to call it color, especially weird since most cell phone cameras would have taken a better color image. http://messenger.jhuapl.edu/gallery/...=2&image_id=88 http://messenger.jhuapl.edu/gallery/...ch%20Image.jpg Remember the Earth flyby, whereas our easily color spectrum corrected as a dark-golden-brown moon was intentionally kept out of frame and otherwise as either too physically dark or perhaps it was invisible due to their intentionally limited DR usage, however the pastel color and/or dynamic range limited image of Earth looked quite nifty. http://messenger.jhuapl.edu/the_miss...galapagos.html http://messenger.jhuapl.edu/the_miss...lapagos_lg.jpg http://www.jhuapl.edu/newscenter/pre...005/050826.asp Is this lack of color imaging all because of Mercury being so gush darn moon like, with similar crater upon crater morphed terrain and of a low amount of albedo, but otherwise offering such a deposited and local mineral rich geology, and subsequently colorful surface as capably imaged by those spendy mirror optics, whereas at least one of which having an extremely good set of narrow bandpass filters and/or spectrum cutoff filters, and with each of those CCD imagers having such terrific DR(dynamic range of at the very least 4X film and that's not even including the extra +/- skew of their CCD DR). So, where exactly are those true colors of Mercury? Perhaps MESSENGER's color imaging potential can be fixed while on the fly, prior to eventually returning for their full orbital mission of mapping Mercury gets under way. . - Brad Guth |
