Listen to the first sounds ever recorded on Mars

For the first time, sound recorded on the surface of another planet has been beamed back to Earth.

But don't worry - it's not an alien demanding to be taken to our leader.

A recording made on Mars by NASA's recently landed InSight craft recorded the sound of its solar panels vibrating. The bassy rumble was caused by winds of up to 25km/h on December 1.

"Capturing this audio was an unplanned treat," said Bruce Banerdt of NASA's Jet Propulsion Laboratory.

"But one of the things [this mission] is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves."

In the original recording, the sound is barely audible - it's a lot clearer pitched up two octaves, as it is in a clip released by NASA.

"Hearing the first sounds ever recorded on the surface of another planet is a privilege - we have a great team, and we're doing incredible things every day at NASA," said administrator Jim Bridenstine.

NASA's next Mars rover is expected to have two microphones, and much better sound recording capabilities.

Two previous missions to the red planet were equipped to record sound, but the first one crashed and the second one's mics were left turned off over fears it would crash the fragile probe's computer.

While it's the first noise from Mars to be heard on Earth, music from our home planet has graced our neighbour since 2015, when Curiosity played 'Happy Birthday' to itself.
