InSight is based on the proven Phoenix Mars spacecraft and lander design with state-of-the-art avionics from the Mars Reconnaissance Orbiter and Gravity Recovery and Interior Laboratory missions.
InSight is more than a Mars mission - it is a terrestrial planet explorer that will open a window into the processes that shaped the rocky planets of the inner solar system (including Earth) more than four billion years ago.
The mission was originally referred to as GEMS (Geophysical Monitoring Station).
