Dragonfly is a planned spacecraft and NASA mission, which will send a robotic rotorcraft to the surface of Titan, the largest moon of Saturn. It would be the first aircraft on Titan and is intended to make the first powered and fully controlled atmospheric flight on any moon, with the intention of studying prebiotic chemistry and extraterrestrial habitability.

From what altitude will they cut Dragonfly helicopter loose on Titan and make it land itself, and what are the main factors determining this altitude?

Titan's surface pressure is about 1.5 bar and because the surface gravity is low pressure falls off much more slowly with altitude than it does on Earth. From Wikipedia's Atmosphere of Titan; vertical ...

How can they be so sure that Dragonfly will "freeze to death" as opposed to simply (and eventually) running out of RTG power? (238Pu decay)

tl;dr: "...will probably freeze to death...before it runs out of power..." If power keeps it from freezing to death and it hasn't run out of power, why would it freeze to death? Space.com's ...

Could a helicopter escape Titan?

Titan has 50% denser atmosphere than Earth and a fraction of the gravity. Could a helicopter-like probe, similar to the Dragonfly or Ingenuity, generate enough lift and velocity to escape Titan? Or ...
