NASA’s Jet Propulsion Laboratory in California released this first-ever audio on Friday, just before Ingenuity soared on its fifth test flight.
You can hardly hear the low hum from the blades of a helicopter spinning at speeds above 2,500 rpm. It sounds like a distant mosquito or other flying insect in the bass.
This is because the 4-pound (1.8 kilogram) helicopter was more than 260 feet (80 meters) away from the Perseverance Rover’s microphone. The rumbling gust also obscured the chopper’s sound.
Scientists have separated and magnified the sound of the rotating blade to make it easier to hear.
The sound was recorded during the fourth test flight of the helicopter on April 30th.
Ingenuity, the first powered aircraft to fly on another planet, arrived on Mars on February 18 and clung to Perseverance’s belly. Its first flight was April 19th. NASA named the takeoff and landing area the Wright Brothers Field in honor of Wilbur and Orville, who flew the world’s first plane in 1903. Ingenuity features stamp-sized wing fabric from the original Wright Flyer.
The $ 85 million tech demo was scheduled to end a few days ago, but NASA has extended the mission by at least a month to increase flight time.
The test flight on Friday afternoon was aimed at twice the altitude (33 feet (10 meters)). The helicopter also headed for the new landing site.
Once the first phase of the helicopter is complete, Rover can begin looking for rocks that may contain microscopic signs of life in the past. Core samples are finally collected to return to Earth.
