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's blades had to rotate about 2400 times per minute to provide lift, a significant advance in propulsion technology.
• Ingenuity doesn't have rear rotor blades for steering, and commands cannot be given in real-time. It takes 20 minutes for a command to reach the planet.
