Comment The "color" images look gray (Score 2) 97
Lame indeed. I just took a look at Messenger's supposed First Color Image of Mercury from Orbit. I thought I'd gone color blind. It looked so gray. Trying to reproduce the subtle shades in a color printer would be a terrible waste of ink or toner, as you'd be forced to go Cyan-Magenta-Yellow (CMY) to print out something not quite Black (K) or gray.
The mission may yet turn up some astounding scientific discovery, but Mercury isn't a very photogenic planet, as far as celestial bodies go.
