The use of line scan cameras for a real-time color pattern inspection grew out of pattern recognition systems in the textile industry, where a single camera with ample lighting can image about 1-m-wide webs. In that application, the complete system was controlled by a 32-b Versa Module Europa (VME) bus microcomputer that also recorded an encoder input for web position.

Another interesting feature of Europa s light scattering near opposition is the double-minima shape of the negative polarization branch (see Figure 13). This effect recently was seen in telescopic observations of Galilean satellites and some bright asteroids [29,30,36]. 

From my chemical perspective. Clue 5 is strong. Right now, 1 think this happened, but if so, it has a lonely side to it. If UV light and dry/wet cycles are needed to form life s molecules, then the other liquid places in the solar system, such as Titan and Europa, are barren without UV-illuminated waters. They would be just as desolate as the moon.)...
