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. |

We might note a correlation between degree of darkening, altitude, and longitude in the light/dark coverage.
Seems like a mathematical model or simulation analyzing sun exposure (insolation), local slope, altitude, longitude, and the Iapetan parameters of ~80 day long 'days' and introduction of a gaseous discoloring agent at aphelion could be made. Program needs to be recursive, the darkening modifies the local temperature and facilitates further darkening. Interesting if someone comes up with some random topology to run through the program to see if it generates Cassini Regio like stains on the object. |
