火星地震学与内部结构研究

Martian seismology and review of Martian interior structure

目前世界多国掀起了第二次深空探测热潮.火星是人类重点关注甚至有移民愿望的行星.美国2018年发射了“洞察”号前往火星探测其内部结构,其科学目标是理解火星形成和演化过程.洞察号搭载了三套科学设备,其中火星地震仪是最为成功的,并取得了若干的研究进展.本文首先阐述火星地震学与内部结构研究进展,包括火星地震事件的识别过程、火星内部结构认识等.然后介绍美国Insight计划实施过程中地震学相关的科学家团队、科学装备以及科学软件平台建设及相应的组织形式,并讨论其对我国开展火星内部结构探测的启示及发展建议.

Recently many countries have initiated the second upsurge of deep space exploration.Mars is the planet that human beings focus on and even desire to emigrate.The United States launched the InSight lander to Mars in 2018 to explore the interior structure of Mars to understand its formation and evolution.The Insight is equipped with three sets of scientific equipment,among which the Martian seismometer is the most successful and has achieved a series of results.This article first describes the research progress of Martian seismology and interior structure of Mars,including the identification of marsquake and the implications of the internal structure of Mars.Then we introduce the seismic team of scientists,scientific equipment,and scientific software platform construc-tion and corresponding organizational forms during the implementation of the Insight project.We also discuss its enlightenment and development suggestions for China's exploration of the interior structure of Mars in the future.
