Listen To The First Marsquake Detected By NASA

As reported by NASA on April 23rd, the first Marsquake was detected by their lander’s seismometer ({SEIS} Seismic Experiment for Interior Structure) instrument on April 6th which marked the lander’s 128th day on Mars (or sol).
What makes this so unique is that it’s “the first recorded trembling that appears to have come from inside the planet, as opposed to being caused by forces above the surface, such as wind. Scientists still are examining the data to determine the exact cause of the signal.”
This event will help scientists understand why the astrological sign Aries needs an attitude adjustment when this is the first detected marsquake on their ruling planet.
Just kidding.
Scientists will be using this Martian Sol 128 event as a sort of x-ray to learn about Mars‘ interior. This will further help us understand how Mars was formed which will lead to a better understanding of how Earth and the moon were formed. They concluded that while the event was too small for any solid data of Mars’ interior, the marsquake was very similar to moonquakes detected during the Apollo mission. Since Mars is relatively quiet, this event also opened up a new field in space exploration, Martian Seismology. (uh oh! send your resumés to NASA!).
The event itself detected three distinct sounds as ground vibrations, “noise from Martian wind, the seismic event itself, and the spacecraft’s robotic arm as it moves to take pictures.”
