Why put a seismograph station on Mars?
This animation looks at a basic physical comparison of the Earth with our closest neighbor, Mars, with respect to size, relation to Sun, gravity, temperature atmosphere, etc. The reason we produced this is because NASA is going to put a seismograph on Mars on the next InSight mission and we thought we could show what we know now about the red planet. The purpose of InSight 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. Does Mars have earthquakes? Is it a layered planet like Earth? How thick are the layers?
InSight Mission to Mars. There is now a seismometer on the surface of Mars monitoring ground motion. Click here to learn more www.iris.edu/insight
