In 2013 the European Space Agency will launch the ExoMars mission to place a fixed lander and rover on the surface of Mars. The payload of the lander includes a broad band seismometer package designed to determine the level and characteristics of seismic activity on Mars. One of the two seismometers constituting the package is an innovative micro machined silicon device covering a bandwidth from 0.025 to 200 Hz with an anticipated noise floor of 0.5 ng/√ Hz. The microseismometer has low mass and is hermetically sealed making it intrinsically suitable for missions where a high level of planetary protection is needed.
Details of the device fabrication approach are presented along with the anticipated performance of the device and the results of early testing. The likely level of seismic activity expected on Mars, the anticipated scientific return and the potential for extending measurements on future missions are discussed. The planned cross calibration with terrestrial reference devices and characterisation under simulated Martian conditions are also described.
