Re: Tidal forces on Titan???

Could Titan be close enough to Saturn so that Tidal forces are constantly changing the surface similar to Jupiter's Moon Io and Europa?

Re: Tidal forces on Titan???

Titan is in a locked orbit, revolution is equal rotation.
HOWEVER, due to the eccentricity of its orbit of 0.029, there will be quite significant tides (far stronger then on earth) with a period of about half the revolution time around saturn.
The tides due to the forced eccentricity of Jo are 1-2 orders of magnitude stronger.
Decades ago, i wrote a short article for the german "Sterne und Weltraum" concerning the tides on Titan. I have the paper not at hand, but if I remember correctly, I think the calculated equilibrium tide hight (deformation hight of an iedal liquid) was about 34 m (on earth it is about 1.3 m)

Re: Tidal forces on Titan???

Preliminary data is sparse.  However, Titan appears fairly flat, Norbert.  A tidal rise anywhere close to 34 meters in a global scale ocean - even less than a quarter of that - would show up as apparent changes in topography every time Cassini passes.

Let's see if you're right.  (It should show clearly enough.)

the only thing is Titan's oceans aren't global, they are more like lakes actually, they can't slosh around like they do on Earth. Titan might have some other oceans however under its surface, much as Europa has.

Re: Tidal forces on Titan???

There have been ideas for planes, helicopters, submarines and balloons. Now its a sample return?

Scientists ponder how to get samples from Saturn's weird moon Titan

Re: Tidal forces on Titan???

If it were not for the billion dollar price tag I am sure Nasa would have done it long ago...

Lucas and Babin Urge NASA not to Diminish Planetary Exploration
http://www.spaceref.com/news/viewpr.html?pid=57465
'The letter comes on the heels of the first images sent back by China’s Mars rover, marking another milestone in the Chinese Communist Party’s (CCP) pursuit of leadership in space.

At the same time, NASA has announced delays in its execution of the Planetary Science New Frontiers Program, which is our primary means of exploring our solar system through missions like New Horizon’s mission to Pluto, Juno’s mission to Jupiter, the OSIRIS-Rex asteroid return, and the future Dragonfly mission to Saturn’s moon Titan. Instead of prioritizing exploration, NASA is increasing its focus on Earth Science and environmental observations.

“China’s accomplishment and the Biden Administration’s retreat from planetary science exploration present a stark contrast today,” Lucas and Babin wrote. “With the significant increase proposed for Earth Science, and the significant decrease from the previously proposed budget request for NASA, we are concerned that a significant reprioritization within NASA will undermine planetary science exploration.'
