On May 5, 2018 the NASA Mars Lander InSight was launched to explore the inner geography of Mars. Although meant to study the planet's core InSight captured the sounds of wind rushing across the Elysium Planitia using geographic sensors. While winds on Mars are a common occurrence this is the first time the winds of mars have been recorded. NASA utilized the lander's seismometer to capture vibrations from a solar array nearby. InSight's air pressure sensor was also used to record Mars' winds and it captured the higher frequencies of the sound. Because these sensors pick up such low frequencies the recordings had to be sped up by over 100x in order to be audible to the human ear. Since Mars' atmosphere is composed mostly of CO2 the atmosphere is thinner meaning the wind's soundwaves have less energy than on earth, despite wind speeds of 10-30mph.
