InSight Project Logo

InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is a NASA Discovery Program mission that landed a single geophysical lander on Mars to study its deep interior in November, 2018. 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 delves 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). InSight has revealed details about Mars interior from crust to core and measured the planet’s current seismic activity. InSight completed its primary mission in 2020, and entered a 2-year extended mission at the beginning of 2021
