The T25 flyby page is now online; however, so far as I can tell, the mission description document isn't available publicly yet.

from the brief description of the SAR observation on the website, it seems like a very useful observation that will give different incidence angles to already observed terrain. Some useful science will come from that hopefully!

How much of an elevation difference will the different viewing angle be able to detect?
(Will we get an idea if the ring around the lakes is flat or a 10 meter cliff?) -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

According to abstract "First stereoscopic radar images of Titan" the heights of scarps around some lakes are up to 600 m!

600 m! Wow! Not much of a beach for surfing Titan.
If this is a general trend, this will make it difficult to spot seasonal differences as lake levels change. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

I would expect to mostly see visibility of features around lake margins change, rather than any obvious relief changes due to the possible fluid height variations. If we're seeing stuff "under the water" near the lake margins, they'll get more visible as the methane-ethane level drops.

QUOTE ISS: New Territory! The area north of Belet, Adiri, and Dilmun will be observed over the next several flybys with some of the highest resolution observations coming in T26. Nevertheless, the medium resolution global map observations at +5 hours from T25 will be very exciting.

Cool! So we can expect an updated Titan map around 2010, right VP?

They will try to extend the SAR observations to have a look at Hotei Arcus.
Could be quite interesting. I heard about several high altitude SAR observations (especially over Tortola) but never found any picture or other informations. What about it ? Marc. |

IIRC, someone recently mentioned the last attempt to do high altitude SAR didn't pan out.

The T12 HiSAR pass didn't pan out, that's correct, but several others have, such as a passes over the Huygens landing site, Tortola Facula, and western Xanadu. Since the RADAR team seems to be releasing products 5 months after they were taken, I would imagine that the Tortola Facula stuff is due sometime late next month, if they plan on also releasing HiSAR products (yes, I rolled my eyes too when I heard that they called their high altitude SAR products HiSAR
 ). But that's only because I am innundated with HiNames all day, every day.
