A recent tweak to Cassini's trajectory allowed an even closer approach of 1,500 kilometers (930 miles) to the Saturnian moon, Tethys, than originally planned, and yielded unrivaled views of the icy moon’s cratered landscape and a look into the gargantuan canyon system called Ithaca Chasma.
What do you think about my 3-D anaglyphics rotating maps of a eleven Saturn's moons?
Using panorama software I created two mosaics from the raw data:
Using panorama software makes for pretty easy mosaics, but the result isn't perfect though. The missing piece in the large one should be rectangular for example. To fix that I'm redoing it by hand in Photoshop. Pretty hard to do and it takes many hours, so fo the time being I like the panorama software result fine ;)
Would Titanians(?) say: "What a big, hot, toxic planet that distant Earth is, so close to the Sun. It's 2/3 covered with molten rock - obviously uninhabitable!"
Size perspective: I always see things like "Tethys is 1/3 the size of Earth's moon". Or "Mars is 1/2 the size of the Earth." That's like saying a tennis ball is 1/3 the size of a soccer ball. Thus we get distorted ideas of how big worlds are. Volume - the true measure of "size" - is proportional to the cube of the diameter.
So in round numbers, Earth (12756Km diam.) is 6-1/2 times the size of Mars (6787Km). Titan (5156Km) is 1/2 the size of Mars. Tethys (1060Km) is 3% of the size of Earth's moon (3476km) or 1% of the size of Titan.
...Of course, if we want to know how many acres it has for golf courses, surface area is proportional to the square of the size.
Thank you ultomatt for writing about the Feb. 17 Mimas flyby. For me, it's interesting to get images of Herschel crater at higher resolution,too. In the actual list of the 2010 tour dates they rescheduled it to the 13th of Feb. , 2010. Shortly after the last one of the 2 very interesting 2009 Enc Nov. flybys there was a flyby of Rhea not listed as a "close" one, but nevertheless having enabled new looks of Rhea. ( with tectonic features similar to Dione ) This perhaps means that at Mimas this will be possible without a close flyby. That Rhea flyby was at 24000km, 15000 mls.
Thank you for writing here of those flybys: Rhea Mar. 2nd and Dione April 6th.
At the Equinox Mission there aren't planned any close flybys of Tethys. But I think that imaging of the remarkably large Odysseus basin ( not only being a 'crater' ) at many better resolution than the best images of it by the Cassini spacecraft available at this moment would be very interesting.
After looking at the actual list of the 2010 tour dates I found those flybys among other ones: On Jan. 10 at Methone at 27000 km, 17000 mls, On Feb. 13 at Mimas at 10000 km, 6000 mls ( as mentioned ) and on June 3 at Tethys, 53000 km, 33000 mls. Perhaps that Tethys flyby will include almost Cassini-class Hi-Res images of the Odysseus basin.
