It has also, as you might expect, picked up on some bona fide marsquakes, which although limited in number are already beginning to reveal a little about the internal structure of Mars. Overall, the team have so far picked up on 100 seismic events, but only 21 are strongly considered to be marsquakes! 4:17 flat Earth - Pathetic sights and sounds from NASA InSight lander on Mars :( YouTube!! The others have no set origin, but it is possible that some of them may be shakes caused by meteorites slamming into the surface.

Insight lander sends back eerie noises from Mars
On the Moon however, seismic activity is far quieter but events can last much longer. That's because there's no running water to seal fractures, so they stay open and reverberate the sound waves for dozens of minutes at a time
But not all sounds are seismic. Insight has picked up plenty of other noises that the science team is learning to recognize. Wind whistling past the spacecraft is a common one, particularly during the Martian day. When the robot arm moves, it can be heard as a sharp, hollow noise.
The most fascinating noises though are what the science team has coined "dinks and donks". These short, repeating noises usually come out at night, and alternate between sounding like dripping water, ticking clocks, and tapping on a hollow metal pipe.

That's the sound of winds blowing across NASA's InSight lander on Mars, the first sounds recorded from the red planet Rather, an instrument designed for measuring the shaking of marsquakes picked up vibrations in the air — sound waves, in other words
Winds blowing between 10 and 15 miles per hour over InSight's solar panels caused the spacecraft to vibrate, and short-period seismometers recorded the vibrations
"You can think of it rather in the same way as the human ear, how we in fact listen," said Thomas Pike, a scientist at Imperial College London who is leading research with the instruments. "The solar panels are like the ear drum. The spacecraft structure is like the inner ear."
Thanks to the NASA InSight probe (and British tools), you can now listen to the sound of a Martian
Scientists working with the InSight's Seismic Experiment for Interior Structure (SEIS) instrument Have recorded four of the so-called 'marsquakes' since the instrument came online but the newly-unveilled 6 April event was the loudest. That date marked the 128th Martian day, also known as a sol, since the mission began and the other quakes occurred on March 14 (Sol 105), April 10 (Sol 132) and April 11 (Sol 133)

"This is what we what we were all waiting for, the first quivering of the planet picked up by our sensors," said Tom Pike, a professor of microengineering from Imperial University London, who helped build the tiny microseismometers for the SEIS.
