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.
