This animation looks at a basic physical comparison of the Earth with our closest neighbor, Mars. In 2018, InSight put an IRIS seismograph on Mars. Why would we do that? The purpose is to study that planet's deep interior by monitoring any earthquakes that are generated and using the information to determine a general picture of what lies below the surface. It quickly answered the question, "does Mars have earthquakes?" It does. Is it a layered planet like Earth? How thick are the layers?
