I'm looking for a recent map ot Titan. Steve Albers's page links to one done by Fridger Schrempp in April 2005. Cassini has done a dozen flybys since then. Does anyone know if an updated map has been released.

Greetings,
Here's a real quick 1K Titan map taking the latest official one from late 2006 and overlaying mosaics from a couple of the recent flybys. As usual this can be refined in the future. Perhaps even some north polar radar mosaics can be added if they are on a suitable projection - a certain map I noticed from EC comes to mind. http://laps.noaa.gov/albers/sos/saturn/tit...cyl_070621c.jpg -------------------- Steve [ my home page and planetary maps page ]

Greetings, Here's a real quick 1K Titan map taking the latest official one from late 2006 and overlaying mosaics from a couple of the recent flybys. Very nice! But it gets me thinking again about the global distributions of different terrains and climates on Titan. The overall picture seems clear: Titan is a semi-desert moon, wet at the poles, very dry around the equator, with an equatorial belt of sand-seas in (it seems) lower terrain. Which raises the following questions for me: 1) Why is the equatorial belt so irregular in shape? Just chance variations in elevation? 2) What constrains the desert belt to north and south? Or to put it another way, what's going on in the temperate zone in terrains that would be deserts if they were equatorial? |

Looking at the global view I see three different units: large areas of bright terrain, the dark 'sand seas' forming an incomplete belt around the crater, and below 30 degrees south a gray area. The gray area appears to have been overlooked in these discussions. Anyone have an idea about why it is it different that the bright terrain with a similar latitude in the northern hemisphere? |
