Engineering marvel
Even though gravity of Mars is 1/3rd of Earth's which helped to offset the effect of the much lower atmospheric pressure (about 6 mbar). But even so, Ingenuity’s blades had to rotate at 2400 RPM (compared to 500 RPM on Earth) to provide the required lift for the 2 kg craft.
Just achieving such a rapid spin rate for the two 1 m long blades was a significant advance in propulsion technology.

The importance if Ingenuity's flight
Ingenuity's flight is a technology and engineering achievement.
- Flight requires lift. On Earth, with an average air pressure of 1000 millibar, a helicopter blade spins at a rate of 400 to 500 rotations per minute to create lift. On Mars, gravity is about one-third of Earth. Ingenuity...
