Massive Mountain Range Imaged on Saturn's Moon Titan
http://saturn.jpl.nasa.gov/news/press-rele....cfm?newsID=709 I'm not so sure I agree with their conclusion, but they seem to think that based on the appearance of the dark "stuff" to the east of the bright streaks at different wavelengths, that that dark "stuff" is topographic shading and that the bright streaks are mountain chains. I am not sure I agree with that statement. I can't go into detail why, but I think bright streaks are some kind of "stain" on the surface, not topographic. The more interesting news is the statement: QUOTE The composition of dunes that run across much of Titan is also much clearer. "The dunes seem to consist of sand grains made of organics, built on water-ice bedrock, and there may also be some snow and bright deposits," Brown said. VIMS was able to resolve the dunes and able to see the compositional differences between the dunes and the inter-dune regions. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
