Has Cassini spotted the formation of a new Saturn moon?
Check out the image. Quite fascinating, though the uncertainties here are quite large.
Using images from Cassini scientists think they have made their first detection of waves on a lake on Titan.
Cassini has obtained its highest resolution images yet of Saturn’s weird hexagon-shaped jet stream.
They’ve even turned it into a movie!
Using Cassini data scientists theorize that the lack of craters in the lowlands of Titan is because those lowlands were swamps that quickly erased the evidence.
Cassini has taken a spectacular full color image of Saturn’s hexagon-shaped storm that surrounds its north pole.

Why has Cassini detected no waves on the lakes of Titan?
Cassini has found hints of activity coming from the Saturn moon Dione.
The spacecraft’s magnetometer has detected a faint particle stream coming from the moon, and images showed evidence for a possible liquid or slushy layer under its rock-hard ice crust. Other Cassini images have also revealed ancient, inactive fractures at Dione similar to those seen at Enceladus that currently spray water ice and organic particles.

The science team for Cassini has released a spectacular mosiac of Saturn and its rings, backlit by the Sun.
New data suggests that the icy crust of Titan is twice as thick as previously estimated.
“The picture of Titan that we get has an icy, rocky core with a radius of a little over 2,000 kilometers, an ocean somewhere in the range of 225 to 300 kilometers thick and an ice layer that is 200 kilometers thick,” [said Howard Zebker of Stanford University]. Previous models of Titan’s structure estimated the icy crust to be approximately 100 kilometers thick.
This means that the methane lakes and rivers of Titan are flowing across a bedrock of ice, which at the cold temperatures there would be as solid as rock is here on Earth.

Data of the tidal fluxes on Titan by the Cassini spacecraft now suggest that there is a liquid ocean below Titan’s icy crust.
The team’s analyses suggest that the surface of the moon can rise and fall by up to 10 metres during each orbit, says Iess. That degree of warpage suggests that Titan’s interior is relatively deformable, the team reports today in Science1. Several models of the moon’s internal structure suggest such flexibility — including a model in which the moon is solid but soft and squishy throughout. But the researchers contend that the most likely model of Titan is one in which an icy shell dozens of kilometres thick floats atop a global ocean. The team’s findings, together with the results of previous studies, hint that Titan’s ocean may lie no more than 100 km below the moon’s surface.

Engineers have gone to a back up radio system on Cassini after a primary unit did not respond as expected in late December.
The cause is still under investigation, but age may be a factor. The spacecraft launched in 1997 and has orbited Saturn since 2004. Cassini completed its prime mission in 2008 and has had two additional mission extensions. This is the first time its ultra-stable oscillator has had an issue.
