Artist's Concept of InSight Lander on Mars: InSight is the first mission dedicated to investigating the deep interior of Mars. The findings will advance understanding of how all rocky planets, including Earth, formed and evolved.

    What are InSight's Science Tools?

    The InSight Lander’s three primary instruments, SEIS, HP3, and RISE, take the first-ever in-depth look at the planet's “inner space.” This trio will study the fingerprints of the process of planet formation, buried deep in the Martian interior. Their measurements shed light on just how warm and geologically active Mars still is, and provide essential clues on the evolution of Mars, and of all the terrestrial planets.
