Instrument class · Ground motion (seismic waves)
Seismometer
An instrument that senses the tiny ground motions of quakes and impacts, probing the interior structure of a world by how seismic waves travel through it — as InSight did for Mars.
Instruments of this class
InSight's ultra-sensitive seismometer, which detected hundreds of marsquakes and, for the first time, revealed the internal structure of Mars.
