A sunset on Mars, as captured by NASA's Mars Exploration Rover Spirit back in 2005.NASA/JPL/Texas A&M/Cornell NASA's InSight robot, the newest Martian resident, has been busy in Elysium Planitia. After unfurling its solar panels and soaking up the sunlight, its instruments began to kick into gear, including both its state-of-the-art seismometer and its air pressure sensor. On December 1st, the ghostly, ethereal sounds of Mars were detected and recorded – and you can listen to them in the newly released video from the Jet Propulsion Laboratory (JPL) below. The first clip you can hear comes courtesy of the seismometer, which picked up the wind causing the solar panels to vibrate. It's barely audible on devices without a decent subwoofer, but fortunately, if you wait a moment, you'll hear the same sounds but two octaves higher.
