NASA showed the first Martian helicopter

NASA's Jet Propulsion Laboratory released a snapshot showing a flight sample of a Martian helicopter. This small aircraft will be launched on Mars this summer along with the Perseverance rover ("Persistence"). The photo was taken on February 14, 2019. An aluminum platform and side supports will hold the helicopter on the rover body.

The first Martian helicopter in history has a mass of 1.8 kg. It is equipped with two coaxial screws with a radius of about 120 cm, rotating at a speed of 2400 rpm. The helicopter’s body is cubic in shape with a side length of less than 10 cm. The maximum flight duration will be 90 seconds, the height will be up to 5 m. The initial project was more ambitious and assumed flights hundreds of meters, the rotor speed should be up to 3000 rpm.
