Titan close flyby & gravity assist (T7) Altitude 1 075 km

Looking forward to the radar swath.








Note: As soon as a preview of the flyby is posted I'll surly link it.

VP will there be any NT on this encounter?

Posted by: volcanopele Sep 6 2005, 01:46 AM

There was a non-targeted encounter of Pandora, taking Cassini within 52,000 km of that satellite, today. Hopefully the images will show up later today or tomorrow morning.

My T7 preview is now up (now my longest post ever):

Odd. Very odd. Few small craters, one or two elongate craters (made by double objects, or made by things shaped like Atlas?)

Oh, and a set of linear parallel markings that look like the grooves on Phobos.

Volcanopele: "My T7 preview is now up (now my longest post ever):"

Really Good Stuff... but I wish you had a "printme" button or used a wider column. When I print out a text-selected chunk like the preview for my brother to read and then to put in the archive, it uses twice the paper it should.

Very Phobos-like indeed!

Anyone know why there appears to be so much noise in the background?

Posted by: tedstryk Sep 7 2005, 10:18 AM

Yes it does, although it is something like 7 times the radius of Phobos.

When Cassini is near periapsis but outside magnetic field lines crossing through the main rings, it's in the highest intensity and highest energy-per-particle section of Saturn's radiation belts. Voyager and Pioneer showed the belts more or less start at Rhea's vicinity and get stronger at Dione and Tethy's radii. and are very strong inwards of Enceladus. Close to this small inner moon, the radiation is near the max possible at Saturn.

Not a healthy place for anything more than a brief visit, then...

Posted by: um3k Sep 7 2005, 02:50 PM

Darn, I guess we won't be seeing a Pandora orbiter, then.

Posted by: gpurcell Sep 7 2005, 05:17 PM

Hm. Observe the shadow on only one rim of the elongated crater. It may be an optical illusion, showing an ellipsoidal shape due to the angle of the moon in that location.

Unfortunately, I can't create a "printme" button with the tools Blogger gives me. I have changed the template, so maybe that should help.

Titan images from T7 starting to show up:

I will be posting links to more on my http://volcanopele.blogspot.com/2005/09/t7-raw-images.html. Also don't forget to search the JPL raw images page for the latest images.

Wow! Is the upper-right feature in the first image "Bazaruto"? And is it a volcano? Where is a good place to catch up on all the recently named features of Titan?

Is the right-center feature that looks like an impact creater with central-peak an artifact of the image and not a real feature? (it seems to have a much higher resolution than the rest of the image).

At the bottom-right portion is something that looks like a large, partially buried crater.

Posted by: volcanopele Sep 9 2005, 01:45 AM

Bazaruto Facula is the ejecta blanket of an 80-km wide impact crater (that is yet to be named) at upper right in the first image. The impact crater is partially covered in dark material (as you can see in the image). A RADAR SAR view of Bazaruto and its crater is available http://photojournal.jpl.nasa.gov/catalog/PIA07368. The USGS has a list of features names as well as a map with names placed on them:

http://planetarynames.wr.usgs.gov/jsp/FeatureTypes2.jsp?system=Saturn&body=Titan&systemID=6&bodyID=30&sort=AName&show=Fname&show=Lat&show=Long&show=Diam&show=Stat&show=Orig

That feature at center right is an artifact caused by dust on the optics of the camera.

Re: the partially buried crater: Not sure which image you are refering to, but there is a known image artifact (a larger version of that donut at center right) right on the bottom right corner. You can clearly see the artifact in the second image.

I hope it was just Human error and not mechanical!?

Bummer. I was really looking forward to this flyby
Hope they fix it in time for the next flyby.

Two for the price of one

Dilo's posted a nice movie in http://www.unmannedspaceflight.com/index.php?showtopic=1384&hl=.

Posted by: volcanopele Sep 12 2005, 07:16 PM

I just want to clarify, this was a human/software error, not a hardware glitch. Project engineers expect to have recorder A back up and running by Tethys/Hyperion flybys.

Also, it looks like some of the SAR swath was salvaged, but I haven't confirmed that.

Posted by: Sunspot Sep 12 2005, 09:09 PM

I hope they managed to salvage some of the Radar data. Wasn't the first half of the radar swath over a more geologically interesting are than the second half?
