The helicopter Ingenuity has logged 36 flights, the longest lasting almost three minutes.
NASA plans to return these samples to Earth a decade from now.
A second microphone, part of the rover’s SuperCam instrument, previously picked up the sighing of Martian wind and the rapid ticking sound of the instrument’s laser zapping rocks to reveal details of their structure and composition. On the prowl for rocks that might contain signs of ancient microbial life, Perseverance has collected 18 samples so far at Jezero Crater, once the scene of a river delta. This first audio of a drive across the Martian surface joins a growing playlist of Mars sounds beamed back to Earth from Perseverance. The results "demonstrate just how valuable acoustic data can be in space exploration." A media teleconference about these sounds will be held today at 12:30 p.m. These recordings allow scientists to study the Martian wind, atmospheric turbulence and now dust movement as never before, Murdoch said. NASAs Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander, which touched down on Mars just 10 days ago, has provided the first ever 'sounds' of Martian winds on the Red Planet. It followed up with audio of the rover driving around and its companion helicopter, little Ingenuity, flying nearby, as well as the crackle of the rover's rock-zapping lasers, the main reason for the microphone. This same microphone on Perseverance's mast provided the first sounds from Mars - namely the Martian wind - soon after the rover landed in February 2021. Of the 84 minutes collected in its first year, there's "only one dust devil recording," she wrote in an email from France.
