Is the one on mars able to operate with really thin air because mars has less gravity?
A "balloon retrieval bot" using battery powered propulsion, launched by another platform such as a rocket (or another balloon!) might be a fun thing for someone at raytheon to pitch.
> The planet's atmospheric density is about 1⁄100 that of Earth's at sea level, or about the same as 87,000 ft (27,000 m), an altitude never reached by existing helicopters. This density reduces even more in Martian winters. To keep Ingenuity aloft, its specially shaped blades of enlarged size must rotate between 2400 and 2900 rpm, or about 10 times faster than what is needed on Earth.
Of course that helps, but the whole design was made for it. It's dual rotors were designed for the environment, and rotate at 2500 rpm+ vs 500rpm for a normal helicopter.
