Presentation Time: 02:00 PM Pacific
Description:
The InSight seismometer (SEIS) has now been operating continuously on the surface of Mars for more than 2 years. In addition to SEIS, InSight comprises a diverse geophysical observatory including a heat flow and sub-surface physical properties experiment (HP3), a geodesy (planetary rotation dynamics) experiment (RISE), and a suite of environmental sensors measuring the magnetic field and atmospheric temperature, pressure and wind (APSS). SEIS has been providing near-continuous seismic monitoring of Mars, with background noise levels orders of magnitude lower than that achievable on the Earth. Since the first detection of a marsquake in April of 2019, the SEIS team has identified more than 500 events that cannot be explained by local environment or spacecraft activity, at least several dozen of which clearly appear to be of tectonic origin and can be analyzed to derive planetary structure. We present a summary of observations and results from the SEIS instrument as well as a summary of other geophysical observations made by InSight during the past two years.
