• NASA released a recording of wind on Mars in December 2022, the first time humans have ever heard a Mars-made sound.
• The recording was captured by the NASA Perseverance rover’s microphone, which was on for less than 85 minutes in the first year of the mission.
• Scientists used the sound to estimate the density of dust grains in the dust devil.
• The wind on Mars is gentle, with atmospheric pressure just 1 percent of Earth’s.
• Dust devils on Mars are caused by hyperlocal temperature differences, which create just the right conditions to kick up swirling dust devils.
• Sound is exceedingly rare in the universe, and scientists are hoping to listen to liquid methane on Saturn’s moon Titan.
