In a nearly three-minute-long historical video, which can be seen on the Youtube page of the US space agency NASA's Jet Propulsion Laboratory, you can see and hear how the small helicopter Ingenuity hovers just above the ground on the red planet.

The video was filmed at a distance of 80 meters on April 30, during Ingenuity's fourth flight on Mars - and it is the first time that a spacecraft has recorded sound from another spacecraft on an alien planet.

- This is a nice surprise, says David Mimoun, professor at the ISAE-SUPAERO space institute in Toulouse, France, who has led the scientific work on the microphone used on Mars.

Recording sound there makes completely different demands than on earth.

The thin air makes all sounds much weaker on Mars, in addition, the cold - the average temperature on the Martian surface is 63 degrees below zero - makes sounds travel more slowly, writes AFP.

Already late on Friday night Swedish time, the mini helicopter made its fifth successful flight.

The 1.8-kilogram spacecraft landed on Mars in February, along with the six-wheeled vehicle Perseverance, and will help explore the planet.
