WASHINGTON: Nasa’s Perseverance rover has for the first time captured the low-pitched whirring of the Ingenuity helicopter’s blades as it flies through the rarefied Martian atmosphere.
The space agency on Friday released new footage shot by the six-wheeled robot of its rotorcraft companion making its fourth flight on April 30 this time accompanied by an audio track.
The nearly three-minute-long video begins with the low rumble of the wind blowing across the Jezero Crater, where Perseverance landed in February on a mission to search for signs of ancient microbial life.
Ingenuity takes off, and its blades can be heard humming softly as they spin at nearly 2,400 rpm on the 872-foot roundtrip.

NASA s Perseverance rover has for the first time captured the low-pitched whirring of the Ingenuity helicopter s blades as it flies through the rarefied Martian atmosphere.
The space agency on Friday released new footage shot by the six-wheeled robot of its rotorcraft companion making its fourth flight on April 30 this time accompanied by an audio track.
In fact, NASA has massaged the audio sample above to help listeners hear Ingenuity. Sounds below 80Hz and above 90Hz have been turned down in volume so that the 84Hz hum of the tiny computer-controlled craft s rotors can be heard.
A small team at mission control has been experimenting with Ingenuity’s limits for about a month. Over that time, the small autonomous aircraft has performed a series of flights at increasing heights and speeds. The flight data is uploaded to Perseverance and sent back to Earth for the team to study, and the video above is taken from Ingenuity’s fourth flight when it traveled 133 metres south and stayed in the air 117 seconds.
