Interesting article in Aerospace America:

QUOTE
Designing Dragonfly, NASA’s Titan Explorer

A planetary lander that can fly to new sampling sites will be able to do far more surface science than a slow, trundling rover. Easy flight in the super-dense atmosphere and ultra-low gravity of Saturn’s cryogenic moon, Titan, makes it the perfect celestial body on which to test the idea. Paul Marks spoke to the team behind NASA’s Dragonfly.

Indeed interesting. And Ralph's book on the Ingenuity and Dragonfly planetary exploration helicopters is an excellent primer to understanding these, uh, "Helirovers".

Great work by the Dragonfly team.

The article refers to the rotorcraft approach as "game-changing." Of course, there is basically one other world where long distance travel by rotorcraft would be new, so I hope we see that particular game be changed sometime this century with a Venus rotorcraft.

The next Titan northern solstice after Dragonfly's will be about 45 years from now, so I think waiting for such a mission to the northern seas, anyway, will fall upon posterity.

Solstice, with it's tilt toward the sun and Earth, is only necessary if the probe is doing direct to Earth communications (and if you want to do some imaging). There have been proposals for lake landers that are short-lived and relay their data back through their carrier craft. They can land and carry out their measurements in darkness.

Fixed-wing (or lighter-than-air) probably makes more sense for Venus. Rotorcraft only come into their own when accessing a planetary surface, which is challenging at Venus owing to the temperatures....

And Titan northern summer solstice is in 2046, which is only 23 years from now, not 45 years.. (recall Titan's year is only 29.5 Earth years long) But I agree that is a dismayingly distant epoch...
