NASA released the first sound ever recorded on another planet – Mars – on Friday.

The sounds of the red planet’s wind was recorded by NASA’s InSight Mars lander, which touched down on Nov. 26.

InSight captured a bassy vibrating rumble deflecting off the lander’s 2-meter solar panels.

Scientists estimated that a northwest wind was blowing at about to 16-32 kilometers per hour. An air pressure sensor and seismometer detected the vibrations on Dec. 1.

“Capturing this audio was an unplanned treat,” Bruce Banerdt, of NASA’s Jet Propulsion Laboratory in California, which leads the mission, said in a press release. “But one of the things [the InSight mission] is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves.”

The raw recording is barely audible.  However, when cranked up two octaves, it sounds like a stiff breeze.

You can hear the audio in this YouTube clip posted by NASA:

InSight aims to help scientists learn about the early development of rocky planets and possibly to find water on Mars.
