Perseverance used one of two microphones to listen like a helicopterIngenuity makes its fourth flight.Footage of a solar-powered flight captured by the Perseverance rover's Mastcam-Z camera, with sound from the microphone of the SuperCam laser device.

Scientists have explained that the laser directs its waveson stones, then studying them with a spectrometer to determine the chemical composition. The instrument's microphone records the sounds of these laser impacts, which provide information about the physical properties of objects, such as hardness. The microphone can also record ambient noise such as the Martian wind.

Since Perseverance was parked at 80meters from the helicopter take-off and landing site, the mission was not sure that the microphone would pick up any flight sounds. Even during flight, when the blades of the helicopter rotate at a speed of 2,537 rpm, the sound is greatly drowned out by the rarefied Martian atmosphere. In the first moments of the flight, it is even more drowned out by gusts of the Martian wind. However, they managed to record sounds.

The press service of NASA noted that as part of the fourth flight, the helicoptertook more pictures of the Red Planet than in previous tests.It is specified that specialists will get access to the images later. The first flight was made by an unmanned helicopter on April 19. Ingenuity was the first spacecraft to fly on another planet.
