US space agency, National Aeronautics and Space Administration (NASA) on Thursday released the sound of lasers recorded by the Perseverance rover from its current location on Mars’ Jezero crater.
The sound was recorded by the microphone attached to the SuperCam mounted on the Perseverance rover.
However, the laser does not sound like what you’d expect it to sound like on Earth – instead of a zap or a ‘pew pew’ sound we’re used to hearing, the acoustic recording of laser shots on Mars sounds more like a continuous snap. The sound was produced from the laser hitting a rock.
Two other sound recordings were also shared, of what an ocean sounds like on Earth, vs what an ocean sounds like on Mars. Windchimes blowing in the wind, bells ringing and finally, humans talking, all of which were also recorded and shared on its Twitter page.
Things are sounding really good here. Listen to the first sounds of wind captured by my SuperCam microphone. This mic is located at the top of my mast. For this recording, my mast was still down so the sound is a bit muffled. https://t.co/0KpN30oIro

Did you know? Some sounds that we’re used to on Earth, like whistles, bells or bird songs, would be almost inaudible on Mars.

The rover carries a pair of microphones which which provides interesting and historic audio of the arrival and landing at Mars, along with sounds of the rover at work and of wind and other ambient noise.
“It is stunning all the science we can get with an instrument as simple as a microphone on Mars,” said Baptiste Chide from NASA’s Jet Propulsion Laboratory and a contributor to the ‘SuperCam’ microphone.
The way many things sound on Earth would be slightly different on the Red Planet. That’s because the Martian atmosphere is only 1 per cent as dense as Earth’s atmosphere at the surface and has a different makeup than ours, which affects sound emission and propagation.
“But the discrepancy between sounds on Earth and Mars would be much less dramatic than, for example, someone’s voice before and after inhaling helium from a balloon,” the US space agency said in a statement.
