The NASA Insight lander on the Martian surface is equipped with an ultrasensitive seismometer to detect and record vibrations, from marsquakes to soft breezes to other unidentified vibrations. On Mars put ears to the ground, ears would not be detected marsquakes. Even the recordings taken by Perception are too low to be audible to humans, however by speeding up the audio and lightly processing it, you’ll be able to listen to marsquakes that Insight captured earlier this year.
The spacecraft’s exquisitely sensitive seismometer, known as the Seismic Experiment for Interior Structure, can pick up vibrations as refined as a wind. The instrument was provided by the Centre National d’Études Spatiales and its partners.
SEIS was designed to listen for marsquakes. Scientists want to research how the seismic waves of these quakes move via the planet’s depths, revealing the deep internal structure of Mars for the first time.
However, after the seismometer was set down by InSight’s robotic arm, Mars appeared shy. It did not produce its first rumbling until this past April, and this first quake turned out to be an odd duck. It had a surprisingly high-frequency seismic signal in comparison with what the science team has heard since then. Out of more than 100 events detected so far, about 21 are firmly thought-about to be quakes. The remainder might be quaking as well; however, the science team hasn’t ruled out other causes.
