Submission + - Listen to the Ingenuity helicopter in flight on Mars (businessinsider.com)
quonset writes: NASA has released a short video of Ingenuity's fourth flight on Mars. However, a bountiful side effect is they were able to hear the hum of its rotors.
Perseverance's microphone was turned on during the flight, and despite Ingenuity being over 200 feet away, it was able to capture both sight and sound of the historic event.
While the majority of sound is Martian wind rustling against the microphone, NASA enhanced the sound to make the rotor sounds more audible. They are most apparent when Ingenuity returns to its takeoff spot and the rotor hum dies down when the blades come to a halt.
