Apparently, the Perseverance Rover builds quite a racket while driving on Mercian terrain. On March 7, NASA released an audio dio recording of the Roger Roger 90-foot drive, which was captured by its entry, descent and landing (EDL) microphone. You will hear the rover’s wheels fall on its red surface as it moves along the bangs and cracks created by the red planet’s mobility system. Vandi Verma, a senior engineer and rover driver at NASA’s Jet Propulsion Laboratory, said: “Many people don’t appreciate that the wheels are metal when they look at the images. When you drive on rocks with these wheels, they are really very noisy. “
It’s so noisy that Dave Gruel, the lead engineer at EDL Systems, said he would pull and call if he heard these noises while driving. Original and undivided 16-minute recordings include high-pitched scratching sounds with rover driving sounds. While Perseverance’s engineering team is still looking for where the high itch came from, they are already looking at a few possibilities. Noises can be made by a mobility system or by electromagnetic interference from one of the rover’s electronics.
That said, NASA has also released a 90-second version of the Dio that filters out some noise:
The Perseverance Rover is giving us the first sounds recorded on Mars. Next to the driving audio Dio, another microphone that is part of its supercam instrument also recorded the sound of Martian wind and the instrument’s laser z app ping rock. “The difference between Earth and Mars – we have a visual sense for that,” Verma said. “But sound is a completely different dimension: to see the difference between Earth and Mars and to experience that environment more closely.”
