Go Cassini! Ring-diving (using its large antenna as a shield) - should make for some very pretty pictures.

Cassini is back in contact and sending images - twenty-one more dives to go.

Cassini, having dived through the 'big empty' once, turns for a second go:

Emerging out of the Cassini mission, there's Dragonfly - a proposal from John Hopkins Applied Physics Laboratory to send a quadcopter probe to Titan:

Yes! A big thick atmosphere, mostly nitrogen, a little methane, traces of other gases. Surface pressure is actually a bit higher than Earth's.
You can hear the sound of Titan's winds, as the Huygens probe parachuted to its surface:

Low gravity too - similar to the Moon's, I think.

Yes – it should be possible for humans wearing wings to fly there, using muscle power alone.

I can see it now - flapping along merrily, through showers of methane rain, hoping it doesn't get too windy!
