First Marsquakes Ever Seen Shake up Science of the Red Planet
A marsquake recorded on the Red Planet on April 6 is the first tremor ever seen on that world. A four-decade long search to detect the first quakes on Mars has come to an end, giving birth to a new discipline — Martian seismology.
The Seismic Experiment for Interior Structure (SEIS) probe, carried to Mars with the InSight spacecraft, detected the tremor. This dome-shaped instrument is capable of sensing quakes deep within the surface of the planet, as well as tremors caused by weather or asteroid impacts.
