The seismometer of Nasa’s Insight lander has revealed details about the deep interior of Mars for the first time. But three research papers based on InSight’s seismometer data have provided much-awaited details on the depth and composition of Mars’ crust, mantle, and core. In the study, the scientists confirmed that Mars’ core, which has a radius of 1,830 kilometres, is molten. “It took scientists hundreds of years to measure Earth’s core; after the Apollo missions, it took them 40 years to measure the Moon’s core. InSight took just two years to measure Mars’ core.”InSight’s seismometer has recorded over 700 marsquakes and many of them between 3.0-4.0 magnitude, supporting the idea that the location is seismically active.
