The US Aeronautics and Space Administration (NASA) unveiled the first audio recording from one of its “Ingenuity” helicopters’ flights on the surface of Mars.

“NASA” reported that the Perseverance probe, which landed on Mars last February, with the small helicopter on board, recorded the sound with a microphone on the fourth flight of “Ingenuity” at the end of April.

This is the first audio recording of a flight on Mars and the first recording made by a spacecraft of another separate spacecraft on another planet.

The helicopter’s sound was not heard well, as the probe picked up the recorded sound from about 80 meters away in the conditions of the Martian atmosphere.

But planetary scientist David Maimon considered the faint, audible sound “a very good surprise”.

He said, “We have done tests and simulations that lead us to the conclusion that the microphone barely captures the sounds of the helicopter, as the atmosphere of Mars dampens the spread of sound strongly.

” “This recording will be a goldmine for our understanding of the Martian atmosphere,” he added.

The Perseverance probe, which weighs about 1,000 kilograms and is the size of a small car, traveled 472 million kilometers on a 203-day journey to reach the Red Planet.

The probe took 8 years to build and cost about $ 2.

5 billion.

Perseverance’s mission is to search for traces of microbial life on Mars and study the planet’s climate and geology
