In some cases, sound can help the team diagnose the health of the rover's internal mechanisms or instruments. The rover may hear the other instruments, internal mechanisms, and hear when we drop off the sample tubes. The microphone also records sounds of Perseverance using its arm, coring rocks, and the wheels crunching against the surface. This gives the rover the chance to hear the sounds of Mars, such as the high-pitched sound of sand grains over the surface, the wind whistling around the rover mast, and low-pitched howls of dust devils passing by. SuperCam can listen for about 3.5 minutes at a time while performing science observations. All without ever driving up and touching it. For example, the hardness of the rock can help tell us whether the rock was formed in a lake or from wind-driven material, or how much pressure was involved in its formation. The intensity of the sound reveals the relative hardness of the rocks, which can tell us more about their geological context. The kind of "pop" it makes tells scientists about the mass and makeup of the rock. At the same time, the microphone hears the staccato "pop" as the laser strikes rock several feet away from Perseverance. SuperCam’s camera and spectrometer can "read" the hot gas to reveal the chemical makeup of the vaporized rock. Hearing the Sounds of a Laser FiringWhen SuperCam fires a laser at a rock, a small amount of the rock vaporizes into a hot gas called "plasma", and heat and vibration creates a shockwave that makes a popping sound. We may even be able to hear the sounds of the rover itself! SuperCam's toolkit also consists of a microphone that will help study Mars rocks and soil. It has Entry Descent and Landing (EDL) microphones that will record the sounds of landing. ![]() Recording the Sounds on MarsEngineers have equipped Perseverance to be a good listener. The Phoenix Lander had a microphone on the spacecraft’s descent camera, but that instrument was never turned on. ![]() Unfortunately, one of those missions, the Mars Polar Lander, failed. NASA spacecraft that traveled to Mars in the past have carried microphones twice. It will make it possible for our robots to not only touch and taste, but finally hear, the sounds of Mars. When the Perseverance rover arrives at Mars, it will have two microphones. Hearing is the last of the five senses we have yet to exercise on the Red Planet. Cameras have given us sight, robotic hands, arms and feet have supplied touch, and chemical and mineral sensors have let us taste and smell on Mars. It does not store any personal data.Robots have replicated much of the human sensory experience on Mars.
