Dione Options

[Guest_BruceMoomaw_*]

Cryptic comment from the latest Cassini status report: "The revised Mission Sequence Subsystem (MSS) D11 baseline plan, based on the final set of Engineering Change Requests (ECR), was presented at the Ground Software Monthly Management Review. There is one more likely ECR to be submitted for D11 addressing a data loss issue that arose in S06." Is this a reference to the data losses that Jason mentions during the Dione flyby?

I just set the f.o.v. of the lens to be 1 degree (I'm not sure what it actually is)

I also used PTGUI to make a Dione mosaic. The FOV for the narrow angle camera is 0.35 degrees and the focal length is 2000mm. Using these settings produces great results with PTGUI:

I have now finally finished doing a preliminary cylindrical map of Dione by adding some Tb images to a Voyager based map. I compensated only crudely for illumination so there are some obvious seams. Also it was somewhat difficult to reverse engineer the viewing geometry due to the low resolution of most of the original Voyager map and the fact that the distances given on the Cassini raw image page are incorrect. Apparently they apply to the trajectory planned before it was decided to double the Iapetus flyby distance. Other distances there are incorrect as well (e.g. the Iapetus images).

This means that the map of Cassini images has some visible mismatches between individual images.

I do not plan to do any high(er) quality seamless maps until I get PDS formatted raw images.

The map can be seen here:

^^WOW indeed!

Do I ever feel lucky that I found this forum! Thanks everyone for sharing all your hard work with the rest of us space tourists!

Great work!
