Much to my surprise, a chunk of the T16 Sar swath as been released:
http://photojournal.jpl.nasa.gov/catalog/PIA08630 An abundance of lakes can been seen. Some appear to be crater lakes (or sinkholes), like the lake at far left on the top cutout. That lake appears similar to Crater Lake in Oregon, with a little island in the middle (you can kinda see the attenuation of the signal surrounding the island as the methane gets deeper). Some lakes appear quite distinctive from the surrounding terrain, like the features on the right part of the bottom cutout. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

In terms of Titanian skygazing, note that the ratio of sunshine (daytime) vs. saturnshine (selected nighttimes) would be much smaller than sunshine vs. moonlight ("moonshine"?!) on Earth. Something like ~6 magnitudes. It would probably be bright enough to read by saturnshine on a Titan night. Has anyone estimated the illumination levels on Titans surface during day/night? Has the Huygens probe measured this directly? Typically, for earth conditions, the following levels are typical: Twilight - 4 lux Full Moon - 0.2 lux No Moon - 0.001 lux |
