Hi,
CASSINI has transmitted 184 pics (!) over the last days. Here five takeouts, 3-4x enlargement: Date: 2009-09-06 Distance: 2.228.548 km Filters: CL1 and CL2 Date: 2009-09-08 Distance: 3.215.284 km Filters: P120 and GRN Date: 2009-09-08 Distance: 3.216.610 km Filters: P60 and GRN Date: 2009-09-09 Distance: 3.390.271km Filters: P60 and GRN Date: 2009-09-09 Distance: 3.427.313 km Filters: P120 and GRN Maybe somebody is able to combine some of those images to show more details. Bye. |

It's quite possible, I was just trying to spark some discussion. Zero phase behavior difference seen here could be pretty interesting. I'm not acquainted with photometry and backscattering properties of different materials. My comment was based on the fact powdery surfaces (very beaten up regolith) seem to show the strongest opposition effect. It could just as well be dependant on the specific materials. The shadowing effect is only a part of the equation, coherent backscatter (if that's what it's called) is I think more important at zero phase. These shots seem to suggest CR shows very little of that effect.
