The instrument includes two independent 3-axis seismometers: a Very Broad Band (VBB) and a Short Period (SP) seismometer. The instrument package is deployed onto the surface and is covered by a thermal and wind shield to protect the instrument from thermal and wind induced noise. The package is connected to the lander by a flexible cable tether.
