This astronaut is equipped with two dedicated commercial microphones, one on the chassis and the other in the supercomputer on the probe rig, so they can record different sounds from the Martian environment.>
Location of perseverance drone microphones
In a video released with explanation from NASA experts, the perseverance-recorded sounds begin to play in about 1 minute and 30 seconds, and the first sound is heard from Mars. It is caused by Martian winds, which are accompanied by images captured by astronauts of Martian demon furnaces and dust movement.
In this video, the sound of a persistent astronaut moving on the surface of Mars can also be heard. Of course, this sound bears no resemblance to the sound of ordinary earth vehicles moving, and instead the sound of tapping and squeaking is created by the movement of six metal wheels on the rocks and sands of Mars.
The next sound in this video is laser blows to rocks. Includes Mars. The laser of the supercomputer tool makes a sound by hitting the rocks, and scientists can use this sound to learn more about the properties of materials. The Supercom Microphone has so far recorded the sound of more than 25,000 laser beats and provided much data to scientists.
Finally, the flight of the "ingenuity" helicopter is heard in the thin atmosphere of Mars. Scientists previously believed that the 80-meter distance between the helicopter and the astronaut on the fourth flight would prevent its sound from reaching the microphone. But the recorded sound shows that the Martian atmosphere is much better able to emit sound than originally thought.
These sounds provide valuable information to scientists, and "Nina Lanza" from "We've all seen these beautiful images from Mars, but when the sound comes with them, it almost conveys the feeling of being in the same environment," the Las Alamos National Laboratory said in the video. p>
