The latest 'looking ahead' gives a nice description of the pi-transfer, introducing the curious concept of a 'rev' that is only half a revolution. It also contains this sentence:
"With Kraken Mare near the field of view, scientists can also use this effort to see how using polarization filters affects the appearance of large bodies of liquid methane on Titan." Titan followers here may remember why I'm excited about that. http://www.unmannedspaceflight.com/uploads...78901_thumb.jpg |

Another set of three using polarisers with the lake in frame today. Again differences are not immediately obvious but somebody might like to take a closer look and maybe make a blink comparison.
