Helicopter to Saturn’s moon

Nasa like the idea of using a helicopter to move around Mars that they are doing one for Saturns moon....

Dragonfly aircraft would fly above the frozen Titan surface

Named Dragonfly, the spacecraft, which is set to launch in 2026 and reach its target in 2034, will function like a large drone, flying to numerous sites, where its science instruments will analyze surface composition, atmospheric properties, and subsurface oceans and lakes to search for chemical evidence of life in both the present and distant past, and determine how far pre-biotic chemistry has evolved.

During its 2.7-year-mission, Dragonfly will visit the most promising sites on Titan in terms of habitability, using the moon’s thick atmosphere to fly from one site to another. Composed of eight rotors, the spacecraft will be the first multi-rotor object to visit and study another world.

The probe will collect samples from a variety of geographic terrains, including the floors of impact craters that once harbored both water and complex organics, liquid reservoirs, and subsurface oceans. Current plans call for it to fly over 108 miles (175 km) around Titan during the mission’s duration.

Sems like a very interesting mission searching for the signs of early....

Helo will work a lot better in Titan's thick atmosphere than it will on Mars.

Re: Helicopter to Saturn’s moon

Which leaves energy in the form of some sort of kilowatt system such as what we are calling KRUSTY....
This is a thermal stirling to electrical power system...

Not much yet on the website for design details.

8 props that are short means high speed and lits of current to run and its 4 motors to drive them at a minimum.
