Abstract
As part of the Payloads and Research Investigations on the Surface of the Moon (PRISM), the Farside Seismic Suite (FSS), will carry a pair of seismometers to the Schrödinger crater. One of these, the three-component Short-Period seismometer, is based on the MEMS seismometer successfully deployed by the InSight mission to Mars. This paper will describe the adaption of the Martian design to operate on the moon and potential future performance improvements made possible by operating in the low lunar gravity and vacuum conditions. Future possible developments of penetrator instruments and measurements in low gravity conditions leading to different deployment techniques will be briefly discussed along with the parallel development with JPL of a high dynamic range low frequency digitizer (DC-100 Hz) suitable for recording this sensor and other geophysical instrumentation in the space environment
