On March 7, the Mars 2020 Perseverance Rover drove for 90 feet (27.3 meters). The EDL microphone recorded the sounds of the driving for a whole 16 minutes and the Mars 2020 Perseverance Rover sent it back to Earth. Our 1:2 Perseverance Mars Rover Replica will also have the EDL microphone and it will be a real microphone so that the user can record sound. The Mars Rover Replica’s EDL microphone will have the same appearance strcuture of the real Mars 2020 Perseverance Rover’s EDL microphone.
Unlike a normal vehicle, the Mars 2020 Perseverance Rover does not have inflatable tires. Instead, the tires are metal, alluminum alloy. Most of us probably wouldn’t know what it is like to be in a vehicle that has metal wheels. The metal rolling against the ground, dust and rocks will generate annoying noise, and the ride will be much bumppier. As expected, you can hear from the video the metal clanking sound, wheel scratching sound, and the motor sound. It is not a pleasant sound but it is exciting to hear just because it is from the Mars 2020 Perseverance Rover on Mars. Our Peseverance Mars Rover Replica perfectly replicates the appearance structure of the Mars 2020 Perseverance Rover’s wheels, steering motors and driving motors. So users can expect to hear the same sound as he or she controls the rover to drive with the remote.

This audio was recorded by the EDL microphone, which was not expected to surrive the landing but it did. Therefore, it was a surprise we receive the audio of the driving from it. However, since the EDL microphone was off the shell and was not designed to do scientific analysis, when the team hears unusual noise, it presents some difficulty to figure what that anomoly is. Some guess it is electromagnetic interference.
