Although the atmosphere on Mars is much thinner than on Earth, it still has enough density to generate the boost for ingenuity. Moreover, it is very easy and can overcome the gravity of Mars so well. The helicopter weighs only 1.8 kilograms on Earth, which is about 0.68 kilograms on Mars.

The rotor blades have a diameter of about 1.2 meters and rotate much faster to generate enough buoyancy.

“Rotor leaves are much larger than normal. They are about 1.2 meters long “

I think you’re confused. The individual Leaves are about 60 cm long – but you probably mean the whole Diameter of the rotor.

yes I mean, of course diameter, thank you for the hint.

The lift of the small helicopter is facilitated by the low gravity on Mars, and it is still very light. In very thin air too, a lift can be generated, for example by larger rotor surfaces or by faster movement of the rotors or by more rotors.

The helicopter is also very light. This also works in a little thinner air. After all, there are real storms on Mars that redesign the surface.

by a very fast rotor.

To keep Ingenuity aloft, its specially shaped blade of enlarged size must rotate between 2400 and 2900 rpm, or about 10 times faster[34] as what is needed on Earth

2400 and 2900 rpm

This is really very fast: 40 to 48 turns per second! This corresponds to the wing beat frequency of a calibration …

Yes. He’s incredibly easy to do. But how to see it works:)
