NASA played for the first time on Friday a recording of the sound of the blades of the Ingenuity helicopter, which succeeded in its fifth flight, in the thin air of Mars, taken by the Perseverance rover. The US space agency has posted on its Twitter account new images of April 30, this time accompanied by sounds. The video, lasting nearly three minutes, begins with the wind blowing over Jezero Crater, where Perseverance landed on February 18. Mars Helicopter then flies away and we hear the sound of its blades spinning at nearly 2,400 revolutions per minute for a round trip of 260 meters in total. <blockquote class = "twitter-tweet" data-lang = "en"> <p lang = "en" dir = "ltr"> Listen closelyđź‘‚ <br> The microphone on <a href = "https://twitter.com/NASAPersevere?ref_src=twsrc%5Etfw"> @NASAPersevere </a> 's SuperCam caught sound during <a href = "https://twitter.com/hashtag/MarsHelicopter? src = hash & ref_src = twsrc% 5Etfw "> # MarsHelicopter </a> 's 4th flight.

May 08, 2021 NASA first played a sound recording of the blades of the Ingenuity helicopter, which succeeded in its fifth flight, in the thin air of Mars, taken by the Perseverance rover for the first time on Friday.

The microphone on @ NASAPersevere's SuperCam caught sound during # MarsHelicopter's 4th flight.
The rumbling is Martian wind, but those rhythmic hums come from Ingenuity.
Scientists made it easier to hear by isolating the 84 Hz blade sound.
