It is the first-ever mission by NASA dedicated to exploring the deep interior of Mars. It will also be the first Nasa mission since the Apollo moon landings to place a seismometer, a device that measures quakes, on the soil of another planet.
About the mission:
InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is a NASA Discovery Program mission that will place a single geophysical lander on Mars to study its deep interior.
But InSight is more than a Mars mission – it is a terrestrial planet explorer that will address one of the most fundamental issues of planetary and solar system science – understanding the processes that shaped the rocky planets of the inner solar system (including Earth) more than four billion years ago.
By using sophisticated geophysical instruments, InSight will delve deep beneath the surface of Mars, detecting the fingerprints of the processes of terrestrial planet formation, as well as measuring the planet’s “vital signs”: Its “pulse” (seismology), “temperature” (heat flow probe), and “reflexes” (precision tracking).
