The GEMS (GEophysical Monitoring Station) SEISmometer
Abstract
The seismic monitoring of Mars is the primary science goal of GEMS (GEophysical Monitoring Station), one of three missions undergoing Phase A development for possible selection by NASA's Discovery Program. This monitoring will be performed by a 3-component VBB (Very Broad Band) seismometer [1] (Figure 1), augmented with three Short Period (SP) channels (Figure 2). The VBB components have both velocity and position outputs. The VBB velocity outputs will be recorded at 20 Hz and at 2 Hz. The VBB position output will be sampled at 0.1 Hz. The SP sensors will be sampled at 100 Hz for normal operations and can be sampled at 200 Hz in a campaign mode. Fundamental interior structure information for Mars will be derived for the first time using state-of-the-art, single-station seismic analysis techniques.
