Tehys-PIA07693.jpgOdysseus70 visiteOriginal caption:"Plunging cliffs and towering mountains characterize the gigantic impact structure called Odysseus on Saturn's moon Tethys. The great impact basin lies before the Cassini spacecraft in one of the best views yet obtained.
Quite a few small craters are visible inside Odysseus (450 Km - or 280 miles across), making it clear that this is not a very young structure. However, a comparison of cratering density between the interior of Odysseus and the surrounding terrain should show whether the large basin is at least relatively young.
Odysseus lies on the Leading Hemisphere of Tethys; North is up and rotated 18 to the right.
The image was taken in polarized ultraviolet light with the Cassini spacecraft narrow-angle camera on Dec. 24, 2005 at a distance of approx. 196.000 Km (about 122.000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 85. Resolution in the original image was about 1 Km (3,831 feet) per pixel. The image has been magnified by a factor of two and contrast-enhanced to aid visibility".

The camera was pointing toward TELESTO at approximately 12,230 kilometers away, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated".
Nota: ricordate il discusso Fly-By di Hyperion durante il quale questa piccola luna rimaneva completamente immobile durante l'avvicinamento di Cassini (vedi "Hyperion", di A. Feltri e P. C. Fienga su NEXUS)? Notate ora come Telesto, invece, cambi VISIBILMENTE posizione tra un frame e l'altro. Sar perch Telesto ruota su s stesso molto pi rapidamente di Hyperion o forse perch Cassini ha diminuito la sua velocit di crociera?
O magari perch queste immagini sono genuine e quelle del Fly-By di Hyperion non lo erano?...
Voi che dite?

Nota: secondo Voi il movimento della Sonda rispetto a Cassini che ha determinato il repentino cambio di posizione di Telesto in questi due frames, oppure Telesto un'altra - vera, questa volta! - "Tumbling Moon" (al pari - presunto - di Hyperion)?!?
