Cassini will fly by Titan today. This time it will image regions not yet covered (http://saturn.jpl.nasa.gov/multimedia/images/image-details.cfm?imageID=1460) (the "Lying H" area mostly).

For the latest images, see this link (http://saturn.jpl.nasa.gov/multimedia/images/raw/index.cfm) (check the newest button and click the Search Images button; "Browse Latest 500 Raw Images" often doesn't show the very latest images).

There are already cool close-ups of Rhea and Epimetheus. Looks like this time Cassini went through periapsis before reaching Titan.

The images are now online. There seems to be many pictures of Titan's crescent and haze layers.

This (http://saturn.jpl.nasa.gov/multimedia/images/raw/raw-images-details.cfm?feiImageID=36058) and this (http://saturn.jpl.nasa.gov/multimedia/images/raw/raw-images-details.cfm?feiImageID=36055) picture shows Saturn behind Titan's haze.

There are also several close-ups from the "lying H" region.

This and some other images seem to be covered with faint egyptian heiroglyphs! For example:
http://saturn.jpl.nasa.gov/multimedia/images/raw/raw-images-details.cfm?feiImageID=36165

Is this an artifact? What's the explanation? Anybody know?

These images are full of artefacts. That white spot is probably a cloud.

No, the white spot is another artifact. It appears dark in images taken with other filters, oddly enough. Must be some exotic material. :P

Cassini was supposed to pass within 1,500 km, but the nearest images I can find are at least twice that distance...did Cassini have a Bo Radley moment?

Wrong. Press release says 1,500 miles. That's about 2400 km. Images may not have been taken right at closest approach, either, if other experiments were more important at that point, and they required pointing Casini's imaging subsystem away from nadir and/or Titan's surface.

If you're referring to the round circles, that's caused by dust in the optics that is out of focus and thus causes a ring instead of a point on the image. The bright white spots a few pixels in size are due to higher energy photons hitting the CCD (ie, gamma rays) and saturating the pixels it hits. The fuzzy bright swaths look like glare to me.

New Titan Territory (http://saturn.jpl.nasa.gov/multimedia/images/image-details.cfm?imageID=1465)

The picture shows the "Lying H" area not imaged before in infrared light, but which has already been partially mapped with the radar.
