During this Phase I, Michigan Aerospace Corporation will adapt the design of an optical MEMS seismometer for lunar and other planetary science instrumentation. The optical MEMS based seismometer takes advantage of the high Q of morphological dependent resonances and can be sensitive to a few nano-g with a proof mass under 80 grams. The three-axis seismometer, originally designed for field applications, will be rugged, compact and low power (<160 mW per channel). During the Phase I effort, MAC will develop the design for the instrumentation, with specific attention to the environmental conditions encountered on the lunar surface, in particular the large temperature excursions and galactic cosmic radiation. During Phase II, an engineering model will be fabricated, tested and demonstrated.
