为火星初步地震调查研制了一种轻型三分量短周期地震仪。由于重量和数据速率的限制,维京海盗号的地震实验远非最佳,但它至少应该提供有关微震水平和地球地震活动上限的信息。如果火星是构造活跃的,那么我们就可以开始研究火星的内部结构、动力学和组成。适度大小的火星地震的良好分布将使确定火星是否有核心成为可能。核心的大小与行星形成的条件有关。
A lightweight three-component short period seismometer has been developed for preliminary seismic investigations of Mars. Because of weight and data-rate constraints the Viking seismic experiment is far from optimal but it should, at a minimum, provide information about the microseismic level and an upper bound on the seismicity of the planet. If Mars is tectinically active a start can be made on the problem of the internal structure, dynamics, and composition of the planet. A good distribution of modest sized Marsquakes will make it possible to determine if Mars has a core. The size of the core is related to the conditions of planetary formation.
