Seismometers deployed on the Moon by the Apollo astronauts from 1969 to 1972 detected moonquakes and impacts, and added to our understanding of the lunar interior. Several lunar missions are currently being planned, including the Commercial Lunar Payload Services (CLPS), the Lunar Geophysical Network, and the astronaut program Artemis. We propose a microseismometer for the Moon: the Silicon Seismic Package (SSP). The SSP’s sensors are etched in silicon, and are predicted to have a noise floor below between 0.3 and 3 Hz (similar to the Apollo instruments between 0.3 and 0.5 Hz, and better than Apollo above 0.5 Hz). The SSP will measure horizontal and vertical motion with the three sensors in a triaxial configuration. The instrument is robust to high shock and vibration and has an operational range from −80C to +60C, allowing deployment under harsh conditions. The first-generation version of this sensor, the SEIS-SP, was deployed on Mars in 2018 as part of the InSight mission’s seismic package. We will reconfigure the seismometer for the lower gravity of the Moon. We estimate that a single SSP instrument operating for one year would detect around 74 events above a signal-to-noise ratio of 2.5, as well as an additional 500+ above the noise floor. A mission lasting from lunar dawn until dusk, carried on a CLPS lander, could test the instrument in situ, and provide invaluable information for an extensive future network.

从1969年到1972年，阿波罗宇航员在月球上部署的地震仪检测到了地震和撞击，并加深了我们对月球内部的了解。目前正计划进行多个登月任务，包括商业登月有效载荷服务（CLPS），登月地球物理网络和宇航员计划阿耳emi弥斯。我们为月球提出了一种微地震仪：硅地震测井仪（SSP）。SSP的传感器采用硅蚀刻，预计在本底以下在0.3至3 Hz之间（类似于在0.3至0.5 Hz之间的Apollo仪器，并且优于在0.5 Hz以上的Apollo）。SSP将使用三轴配置中的三个传感器来测量水平和垂直运动。该仪器具有很高的抗冲击和振动能力，工作温度范围为−80C至+ 60C，可在恶劣条件下使用。作为InSight任务地震软件包的一部分，该传感器的第一代版本SEIS-SP于2018年在火星上部署。我们将重新配置地震仪，以降低月球的引力。我们估计，运行一年的SSP仪器将检测到信噪比高于2.5的情况下发生约74个事件，以及高于本底噪声的500多个事件。由CLPS着陆器执行的，从月初一直持续到黄昏的任务，
