Sounds from Perseverance rover on Mars surprises scientists
NASA’s Perseverance rover, which landed on Mars in February 2021, has two microphones that are recording hours of audio every day.
As the rover explores Mars, it’s almost unsettling to imagine its world where the wind is gentle, and the air is silent.

Perseverance seems to have a lot to say.
