There are two microphones on board the NASA Perseverance mission: they recorded about five hours of different sounds, for example,
You can listen to sounds from Mars here.
Martian sounds contain strong bassvibrations, so when you put the headphones on you can actually feel them. I think microphones will be an important asset for future Mars and solar system science.
Baptiste Chide, a planetary scientist studying data from microphones
Sensors record how sound travels on Mars. Because the planet's atmosphere is much less dense than Earth's, high-pitched sounds are harder to hear.
Sound on Mars travels much further than we thought. This shows us how important it is to do field science.
Nina Lanza, LANL employee
The information obtained from the helicopter allowed the researchers to rule out two of three models developed to predict sound propagation on Mars.
