Rev 206 and T103 http://www.ciclops.org/view/7901/Rev206?js=1
T103 is another approach to the southern sub-Saturn hemisphere. An interesting area visible in the approaching T103 images is the region of Chusuk Planitia http://planetarynames.wr.usgs.gov/Feature/...AFF85346635F19C This area was imaged by VIMS in one of its highest resolution views of Titan’s surface (500m/pixel). An important paper in Icarus by Jaumann et al http://www.barnesos.net/publications/paper...on.on.Titan.pdf analyzed the VIMS spectral properties of the star shaped Bohai Sinus and adjacent Chusuk Planitia regions concluding that fluvial mechanisms and particle size/composition were responsible for the complex but systematic spectral changes noted. This paper was discussed before in this forum http://www.unmannedspaceflight.com/index.php?showtopic=4724 although not all had access to all figures and text. Since its publication there have been two equatorial storms (April 2008 http://www.unmannedspaceflight.com/index.p...c=6146&st=0 and Sept 2010 http://www.unmannedspaceflight.com/index.p...t&p=164604) and a SAR topo map http://web.mit.edu/perron/www/files/Aharonson13.pdf that lend support to the paper’s conclusion. The Chusuk Planitia region is under consideration for future missions to Titan 's surface. http://solarsystem.nasa.gov/docs/pr344.pdf EDIT: a new link to a more readable version of the Jaumann paper has now been inserted above. |

The T103 flyby 'Mission Overview' http://saturn.jpl.nasa.gov/mission/flybys/titan20140720/ is now up on the Cassini website.

Just curious how the basemaps are doing nowadays. The looking ahead depiction looks nice for the north polar region. What global image mosaic was used for the looking ahead (if it is available)?

Not certain where or if the Titan map files that are used in Looking Ahead are available. The Celestia Program 1.6.1 (I think thats still the latest version available) is used to create the images for Looking Ahead but the graphic map for Titan is not the one that is available with that program. My presumption is that Jason Perry (Volcanopele or VP) updates a custom map of Titan from calibrated and carefully processed ISS images and uses that in the Celestia program to produce the Looking Ahead graphics. Perhaps VP or John VV http://www.unmannedspaceflight.com/index.p...st&p=209464 can comment on this.

I do need to update my map
it also is not 100% scientifically accurate i remove seems and clean up the image I guess i could take a break from the 65535x32768 mercury map as i recall the cyclops map is the JPL one http://www.ciclops.org/view/6924/Map-of-Titan---April-2011 or the one colored by : Dr. Fridger Schrempp http://www.celestialmatters.org/?q=node/56 also the default titan texture in the SVN 5229 ( basically 1.7.0 ) CODE svn checkout svn://svn.code.sf.net/p/celestia/code/ celestia-code is the old 2006 map |

Terrific render T_oner !!! Can one load that into Celestia and use it with the program?

here is a "cleaned up" 4096 x 2048 ( -180 to 180 ) sepia toned map
the CYCLOPS 2011 map https://drive.google.com/file/d/0B6ZYAd08tZ...dit?usp=sharing some of the missing area in the north was added from the radar data a 1024x512 preview for those that do not know already The program Celestia uses images that have zero longitude in the center CODE +90 north -180 W to 0 to +180 E -90 south and there is a tutorial for using "SPICE" for the orbits and spacecraft trajectories http://forum.celestialmatters.org/viewforum.php?f=18 that whole section is on using the NAIF SPICE kernels |
