It provides a different overall sound than the SuperCam audio recording from the mission’s first sol. Some wind can be heard, especially around 20 seconds into the recording.

Por NASA Podcast #Recomendado Tweet First Acoustic Recording of Laser Shots on Mars This is the first acoustic recording of laser impacts on a rock target on Mars from March 2, 2021, the 12th sol (Martian day) from Perseverance’s SuperCam instrument. The sounds of 30 impacts are heard, some slightly louder than others. Variations in the intensity of the zapping sounds will provide information on the physical structure of the targets, such as its relative hardness or the presence of weathering coatings. The target, Máaz (“Mars” in Navajo), was about 10 feet (3.1 m) away. Credit: NASA/JPL-Caltech/LANL/CNES/CNRS/ISAE-Supaero

Por NASA Podcast #Recomendado Tweet First Audio Recording of Sounds on Mars This recording was made by the SuperCam instrument on NASA’s Perseverance Mars rover on Feb. 19, 2021, just about 18 hours after landing on the mission’s first sol or Martian day. The rover’s mast, holding the microphone, was still stowed on Perseverance’s deck, and so the sound is muffled, a little like the sound one hears listening to a seashell or having a hand cupped over the ear. Just a little wind can be heard. Credit: NASA/JPL-Caltech/LANL/CNES/CNRS/ISAE-Supaero
