Hi,
as june begins, time to open this thread...  As said before there will be another Iapetus campaign in the second half of this month - from 17th until 27th. Unfortunately the minimum distance will only be around 1,3 mio. km, resolution about 8,1 pxl/km. Also the short Celestia-animation again:

Number of downloads: 816Just remove *.html and run the avi-file preferably on a DIVX-player. Bye. |

Hi,
the first two june-shots of Iapetus are online. Here an enlargement:
Date: 2006-06-05 Distance: 4.212.487 km (!) Filters: CL1 and CL2 Remarkable the 2 giant impact bassins, one at the dark-bright border and the other one at the bottom - more difficult to see - in the dark area. Bye. |

Hi,
CASSINI transmitted further 31 Iapetus images. Some widefield pics are also among them - maybe some positioning control or do they probably try to find some Iapetus coorbitals? But these should be about 30° before or behind Iapetus...  This was taken: June 21st - 11 tele/4 widefield pics June 22nd - 14 tele/2 widefield pics Here two takeouts , ~3x enlargement:
Date: 2006-06-22 Distance: 1.398.591 km Filters: CL1 and CL2
Date: 2006-06-22 Distance: 1.398.128 km Filters: P60 and MT2 And a widefield view:

Hi,
back again with some weird pics from Iapetus... An astonishing number of 151 images was taken on june 23rd alone. But there are 124 among them showing only star fields - no Iapetus at all! And these are no widefields! Have a look for yourself... Are they probably trying to find some Iapetus moons? Or are thes pics taken at the Lagrangian points? This was taken: 124 starfields 7 widefields 14 tele pics 6 half-Iapetian overexposures (3 of each half) Here some takeouts, ~3x enlargement:
Date: 2006-06-23 Distance: 1.343.121 km Filters: CL1 and IR3
Date: 2006-06-23 Distance: 1.343.092 km Filters: P120 and UV3 Note, the 'Moat / Snowman' is slowly getting visible at the right limb! Here two overexposured halfs stacked together:

Hi,
the next Iapetus image series is online, this time 47 pics. This was taken: 24 starfields 6 widefields 17 tele pics including 3 overexposures Here some takeouts, ~3x enlargement:
Date: 2006-06-24 Distance: 1.368.986 km Filters: CL1 and IR3
Date: 2006-06-24 Distance: 1.416.632 km Filters: CL1 and CL2 Hence CASSINI is slowly diverging from Iapetus, really too bad that the 'Moat / Snowman' is now getting more and more visible at the right limb... Overview through the Solar System Simulator:
Btw., any news on those starfield images? Bye. |

Hi,
I'm still curious about those starfield images, but I don't believe that they're tracking errors. In many pics Iapetus is pointed exactly! The only sense for taking those starfields I could guess is the finding of moons in the vicinity of Iapetus or Iapetian trojans 60° apart. 120° field of view from Saturn showing Iapetus and CASSINI, the Lagrangian points therefore are at the left and right image border:
Of course CASSINI is not at one of those Lagrangian points but as close to them as it can get in its orbit and there is plenty of time to take these photographs now even if there is no other target than Iapetus. Bye. |
