The Perseverance rover makes a lot of noise while moving on the ground of Mars. NASA released an audio document from the rover's motion in the Jezero Crater on March 7, which was recorded by the Input, Descent and Landing Microphone (EDL). You will hear the rover wheels spin on the surface of the red planet as it moves, along with the bumps and cracks created by its mobility system.
According to Vandi Verma, senior engineer and rover driver in her Jet Propulsion lab NASA"Many people, when they see the pictures, do not know that the wheels are metal and what exactly it means. "You drive with these wheels on rocks so driving is really very noisy."
It is so noisy that Dave Gruel, the chief engineer of the EDL system, said he would ask for a tow if he heard these sounds while driving his car. The original and unfiltered 16-minute audio document contains a loud scratching noise along with the rover driving sounds.
Perseverance's team of engineers still do not understand where the intense scratching came from so they are considering some options. The sounds could have been made by the mobility system or could have come from electromagnetic interference from one of the rover's electronic boxes.
However, NASA also released a 90-second audio clip that filters out some of the noise:
The Perseverance rover offered us the first sounds recorded on Mars. In addition to this driving experience sound, another microphone that is part of the SuperCam instrument recorded the winds of Mars. "We have a picture of the visual variations between Earth and Mars," Verma said. "But sound is a completely different dimension: you see the differences between it Land and Mars and you experience the environment more effectively. ”
