The Seismic Experiment for Interior Structure (SEIS) is a seismometer and the primary scientific instrument on board the InSight Mars lander launched on 5 May 2018 for a landing on 26 November 2018; the instrument was deployed to the surface of Mars on 19 December. SEIS is expected to provide seismic measurements of marsquakes, enabling researchers to develop 3D structure maps of the deep interior. Better understanding the internal structure of Mars will lead to better understanding of the Earth, Moon, and rocky planetary bodies in general.
SEIS detected marsquakes in Cerberus Fossae in 2019.
On 24 December 2021, the seismometer for the InSight mission on Mars detected a large seismic event with a distinct signature. The event was caused by a meteor impact on the surface of Mars, which was confirmed by satellite observations of a newly formed 150-meter crater. [3] As of 21 December 2022, which marks the official end of the InSight mission, SEIS has detected a total of 1319 marsquakes.[4]
