NASA绘制的内部构造图

北京时间7月23日消息,在“洞察号”火星探测器的帮助下,美国宇航局(NASA)首次公布了火星的内部构造图。这是研究人员首次对另外一个星球的地质构造进行绘图。

自从2018年11月登陆火星以来,“洞察号”在行驶过程中一直在倾听火星地震,并跟踪它们的地震波。学术期刊《科学》周四发布了三篇论文,利用了“洞察号”收集的数据。论文显示,火星就像一个大型糖果宴,它的地壳被火山巧克力分成了两层或三层。下面的地幔有一个异常巨大、坚硬,像太妃糖的填充物。火星核心出奇得亮,更像是一个糖浆似得核心,而不是牛轧糖似的中心。

再加上NASA和中国火星车近期在火星表面的活动,这些任务都表明火星和地球有明显不同。
