Robot Perseverance belong to NASA re-transmit the sound recorded on the surface Mars. After previously sending out wind sounds and laser shots, this time we can hear how the engine and Perseverance wheels sound as they move around Mars.
This sound was recorded by the entry, descent and landing (EDL) microphone on March 7, when Perseverance underwent its first test drive at Jezero Crater. From the 16-minute recording, a clatter can be heard as six Perseverance metal wheels cross the rocky surface of Mars.
“If I hear a sound like this while driving a car, I will stop and call a tow truck,” joked Perseverance Lead Engineer Dave Gruel, as quoted by the Independent, Friday (19/3/2021).
“But if you take a moment to consider what was heard and where it was recorded, it makes perfect sense,” he continued.
NASA released two versions of this recording, the first, unedited, 16 minutes in length, and the second, which is shorter and has been edited to eliminate the noise behind it.
This first version of the footage contains a mysterious high-pitched scratching sound. The Perseverance team is still researching the origin of this strange sound, but they suspect this sound is being emitted by a mobility system or electromagnetic interference from one of the electronic boxes.
Perseverance has two microphones. The first microphone is used to record wind gusts and laser shots which are part of the SuperCam instrument, and the second microphone is supposed to be used to record the landing process.
This second microphone was unsuccessful in recording the sound of Perseverance’s arrival at Mars, but fortunately it can record sound during the first test drive.
“A lot of people, when they look at the pictures, don’t appreciate that the wheels are metal. When you drive these wheels on rocks, it’s actually really noisy,” said Senior Engineer and Rover Driver at NASA JPL, Vandi Verma.
Despite sending a fair amount of data, the Perseverance mission at Mars just started. Currently the rover is still looking for the right location to launch the Ingenuity helicopter, before starting to dig and collect samples to look for signs of life on Mars.
If this flight is successful, Ingenuity will be the first vehicle to fly on another planet. Ingenuity then has 31 Martian days to complete five test flights on the Red Planet.
