Insight任务预计从2018年底开始在火星上运行一个地球物理观测站至少两个地球年。Insight包括一个地震计套装SEIS。MarSquake服务(MQS)是为了提供从火星返回的地震数据的第一次手动审查而创建的。MQS将探测、定位、量化和分类地震事件，无论是构造事件还是影响事件。已经开发了一套新的和经过调整的方法，以便能够使用单个台站在全球范围内对地震事件进行定位和量化，并开发了支持这些方法的软件框架。本文描述了SEIS将记录的预期信号，用于识别和解释这些信号的方法，并回顾了计划中的MQS操作程序。对于每个地震事件，MQS将使用所有可用的物体和表面相来定位事件，使用对火星结构的最佳估计，随着更多火星浮冰的识别和定位，这将变得更加准确。MQS将管理火星地震活动目录，所有事件都将重新定位，以使用修订后的结构模型套件，因为它们被引入。
The InSight mission expects to operate a geophysical observatory on Mars for at least two Earth years from late 2018. InSight includes a seismometer package, SEIS. The Marsquake Service (MQS) is created to provide a first manual review of the seismic data returned from Mars. The MQS will detect, locate, quantify and classify seismic events, whether tectonic or impact in origin. A suite of new and adapted methodologies have been developed to allow location and quantification of seismic events at the global scale using a single station, and a software framework has been developed that supports these methods. This paper describes the expected signals that will be recorded by SEIS, the methods used for their identification and interpretation, and reviews the planned MQS operational procedures. For each seismic event, the MQS will locate events using all available body and surface phases, using the best estimates of the Martian structure, which will become more accurate as more Martian marsquakes are identified and located. The MQS will curate the Mars seismicity catalogue, with all events being relocated to use revised suites of structure models as they are introduced.
